Subject: Tube alignment problems Sent: Sunday, December 31, 2000 16:05:06 From: SKBROTHERS@aol.com Finally, after receiving my ETX-90EC for Christmas I had a small window of opportunity (Break in the clouds) to see the Moon, Jupiter, Saturn, and Venus. All I can say is WOW!!! This scope has renewed my father's interest in amateur astronomy and may lead him to purchasing an ETX-125 in the near future. The moon was absolutely jaw dropping. I will say that I was a little disappointed in the view of Saturn. The rings were very crisp and distinct but the planet as a whole was very small, even with the 2x Barlow/26mm Super Plossl combo. I am hopeful that the addition of a 9.7mm super Plossl will remedy this situation. I do have a question. I tried to align my autostar and in doing so discovered what I think may be a flaw with my scope. My declination setting circle I feel is not properly installed. When I level my tube I get a reading of 81degrees not 0 degrees as is indicated in the manual. To get a reading of 0 degrees My tube ends up slightly off of the zenith. Have you encountered this issue before? Can the declination circle be manually reset (my tentative attempt to manually rotate the circle was fruitless). Let me know what you think. I'm looking forward to a lifetime of use out of this fantastic piece of equipment. email@example.com P.S. What eyepiece do you recommend for viewing nebulas. I zero'd in on the Orion Nebula and couldn't resolve any of the cloud with my 26mm super plossl. Will a 40mm be better?Mike here: The DEC setting circle is adjustable. Just slightly loosen the DEC lock knob and reposition as needed. Retighten the knob. With the 26mm eyepiece, you'll get a good view of M42 in Orion. You really can't resolve details in many nebulae but with dark skies and dark-adapted eyes you can see some wisps. More aperture and/or perhaps a nebula filter (see the Accessories - Filters page on my ETX) can help too. Lower power can also help with some nebulae.
Subject: Thank you & 3 questions Sent: Sunday, December 31, 2000 11:59:41 From: Chad Shahin I have known about ETX for a while but seriously started looking at it a few days ago when I came across a Discovery store. I ran into your site last night and as a long time user of the Web, I was very impressed with the depth of your information. Everything I ever buy I research the heck out of it on the net first. On your site I finally got to see actual pictures of what to expect out of the ETX and that was one of the best things about your site. I also now have a better understanding of what extras I need and a big question on whether or not to buy used was answered (eBay prices are not far from the new and with the risk of problems and like the support of a dealer is the way to go if you are looking to get into this for the long run). So Thank You very much for your time, and I will repay you by spending many hours reading every part of you site. Now three questions: I am already tapped out for x-mas, but looking at the tripod offer that ends today is tempting (the ETX-90EC). I assume the tripod is very useful. So I guess the question is if this tripod offer is the kind of thing that comes around again soon (or even the Autostar instead - since I am going to get it also)? $200 is quite a bit of savings. I live in Irvine, CA and also spend a time in San Pedro and Torrance area (I lived in San Pedro for half my life and lots of friends that I still visit in that area). Are there any amateur groups in either South Orange county or South Bay? I assume that in time I will come across the site that lists them but I thought since you're from the local area you might know the site that lists them. I live in North Irvine - near the hills (relatively speaking). So kind of like area. Is it correct to assume that is dark enough? I have read that sometimes being in sub-urban area, the brightness factor is mitigated by the fact that the microclimate above such area helps lessen the air disturbances above.Mike here: Sales and promotions come and go. No way to predict them except by noting they seem to occur around holidays, financial quarter ends, and year ends. As to user groups, there is the South Bay Astronomical Society that meets in Torrance. There is also a group somewhere around Irvine or Oceanside but I forget their name. Your local telescope dealer might be able to help. Depending upon what you expect to see, your location may or may not be dark enough. For the planets and Moon, you'll be OK. For the brighter nebulae and galaxies you'll be OK.
Subject: Re: Celestron E-support Sent: Saturday, December 30, 2000 23:57:56 From: firstname.lastname@example.org (Rob\Karen Elgert) I have noticed that in the last couple of posts, you mention that both Meade and Celestron have no e-mail address. While this is technically true of both companies, at least Celestron has a tech support page on their site to which you may send the tech department questions and requests. Both times I have used this service, tech support has e-mailed me back within 1 working day. It's not e-mail exactly but it works just as well and the responses are quick. Infinitely better than Meades "ignore em and hope they'll get tired and go away" policy regarding e-mail. Just wanted to clear that up - RobMike here: Thanks! I missed that when I was checking their site; I was looking for an email address.

Two nights ago i disassembled that arm on my ETX90/ec to perform the "tune up" degreasing procedures listed at http://www.weasner.com/etx/techtips/tuneup.html The aluminum disk is completely separate from the knob, and floating free on my scope, which was assembled on April 13th, 1999. (or at least QC'd that day, based upon the scribble at the end of the optical tube, seen when looking into collimating it.) When you clamp the Dec lock, it pinches the disk between the plastic of the drive shafts and the knob. I even had aluminum shavings collected on the ends of my shafts. I can't comment on relative shininess of plastics. --dick
Subject: re: fuzzy image with an ETX90 Sent: Saturday, December 30, 2000 21:17:54 From: firstname.lastname@example.org (richard seymour) To: email@example.com Another possible source of the fuzziness is a mis-assembled eyepiece. It can either be not fully screwed together (does it rattle if you shake it? it shouldn't) Or one of the lenses in backwards. That's harder for a first-timer to tell, but the outermost surfaces should be fairly (but not -dead-) flat. If one end's lens bulges a lot further out than the other end, then the bugly end is probably in backwards. The -best- fix is to take it to a good telescope store and have someone there flip it. You -can- certainly do it yourself, but you need to be -CAREFUL- and do it on a lint-free SOFT surface. (you WILL drop a lens... and you don't want it to bounce or chip). When reassembling it's REALLY REALLY easy to cross-thread the holders. good luck --dick
Subject: ETX 90 Questions Sent: Saturday, December 30, 2000 18:49:51 From: firstname.lastname@example.org (Cullen Demko) I just purchased an ETX-90EC and have a couple of questions. First, when checking it out and setting it up during the day, I focused on a telephone pole some distance away and was a bit surprised at the fuzziness of the image. I attempted to focus, slowly as the manual suggests but to no avail. Am I expecting too much? I assumed I would be seeing crystal clear images. The image in the viewfinder was good. Also, I'm probably putting the cart before the horse a bit, but I've always been interested in astrophotography. Is the ETX suited to producing decent photos? How about with a CCD imager? Do you have any experience with SAC's imagers? Being on a bit of a budget, the price of theirs is pretty attractive. I appreciate you taking the time to answer my questions, I'm sure with time I'll come up with more. Thanks again Sincerely, Cullen DemkoMike here: You'll find tons of answers to your current and probably future questions on this ETX site. If you were viewing that telephone pole through a window or screen you were distorting the image. Take it outside and try it. If you were outside then there should be no fuzziness if the pole was hundreds of feet away. Try the Moon or a planet and see if you can reach a sharp focus. As to astrophotography (film, digital, and CCD) look through the examples on this ETX site. Also check the Accessories - Showcase Products page for comments on the SAC CCD.
Subject: ETX 90 lens cap stuck Sent: Saturday, December 30, 2000 13:59:33 From: email@example.com (Mark Hanford) I was wondering if you've heard of this problem. I bought an ETX90EC two days ago at Scope City in San Francisco. When I was in the store, one of the salesmen was on the phone with a woman who purchased an ETX and was having problem getting the lens cap off -- she claimed it was stuck. The salesman told me he'd had several calls complaining of the problem. Before I purchased the scope, he unpacked it from the box (which had obviously never been opened) and check the lens cap to make sure it would come off easily. It did. He then screwed it part way back on and warned me not to screw it on too tightly. Not a problem. I got it home and had no trouble removing the lens cap and trying it out. Then, I replaced the cap, being careful not to tighten it down, though I think I did screw it on a bit farther than the sales guy. The next night, when I went to remove the cap, it was stuck! Try as I might, I couldn't get the damn thing off. I ended up getting a small screwdriver and carefully and lightly pried on the edge of the cap. That seemed to do the trick, as I was then able to unscrew it normally. It was like the cap was cross threaded, but I definitely didn't cross thread it when I put it on. My theory is that the cap can be screwed on to the point that the threads on the cap drop below the threads on the inside of the scope. Have you heard of this problem? Is there a missing gasket or o-ring on the lens cap which normally keeps this from happening? I'm going to try to solve it by putting a couple of rubber bands around the cap so it can't be screwed all the way down. Or maybe I'll go get an o-ring. Anyway, it was a frustrating problem to have with a brand new scope. Thanks. MarkMike here: Sometimes the cap can become stuck and users have loosened the corrector lens assembly. Cross-threading or just putting it on too tightly are common causes. It is easy to cross-thread in the dark or even in the light. I have noticed this myself but have always been able to unscrew it with a little extra effort (and care). I'd be cautious about adding rubber bands or an O-ring; debris from the rubber material could be flaked off and get onto the corrector lens.
Subject: The Story of Three Scopes Sent: Saturday, December 30, 2000 13:25: From: firstname.lastname@example.org (peter zimmerman) Early in December I fell in love with the idea of getting the ETX-90EC to replace my original ETX-90. The idea of a GOTO telescope seemed fantastic, and once I got my 'scope aligned correctly (much harder than the adverts, reviews, and instructions indicate), it was great. I could snap between M42, Jupiter, Saturn, and M31 in just a few minutes with a few key pushes on the Autostar and get each object right in the view of my 40 mm eyepiece on the first try. Felt almost like cheating, and the ETX-90 optics are very, very good. But the mechanicals are not, and I am now on my third ETX-90EC in four weeks. Let me describe this not very pleasant story. Telescope 1) Bought in early December. Everything seemed fine, except that when I tried to put a camera on the camera port I found that the mirror pivot was binding. It squealed like the proverbial stuck pig, loud enough to scare my cats and to get my wife's attention from the far end of the house. A couple of flips and it became obvious that this was not just the result of sitting in one position for an extended period. In all likelihood the pivot and axle hadn't been lubed at the factory, a pure failure of quality control (QC) and final inspection. I called Meade and was advised to try squirting WD-40 on the pivots from _*inside*_ the camera port and with the mirror in the 'up' position blocking access to the OTA. Even so, I was unwilling to squirt a greasy aerosol into a cavity with direct access to the optics and opted to return the telescope. I wasn't entirely upset, because the collimation of the tube, while acceptable, wasn't up to the collimation on my original ETX-90 RA Telescope 2) Lordy, what beautiful optics! Unfortunately, it wasn't mechanically as good. The DEC lock had a lot of play, more than 5 degrees, and the clutch had to be tightened rather more than I was comfortable doing in order to initiate tracking. In addition, the little tape that serves as the RA setting circle was binding and would not move, no matter what I did under Meade's instructions. And the DEC setting circle was 10 degrees off, but that's trivial to fix and should probably be trued up once in a while anyway. But the real problem was in the cover plate for the right fork arm assembly. Two days ago I was standing next to the telescope on its tripod when I heard a 'sproing' and felt the impact of a small pellet. The pellet was a chip out of the ring around the pseudo-setting circle under the DEC lock knob, and the sproing was a significant crack in the plastic. No, the DEC lock was not overtightened; in fact it was fairly slack. I called Meade for advice and to request a new cover plate. They declined to provide a part ("it would void your warranty to dig that far into the telescope, sir; it's more complicated than it looks") and advised me to return the telescope for an exchange, which I did yesterday. Discovery was again very generous about making a swap. This seemed to me an example of poor design or poor checking of parts coming in the door (or both), and an example of what happens when you fail to implement W. Edwards Deming's principles of designing in quality and doing it right the first time. Inspecting for quality costs money in rejected items and may cost even more money in warranty claims which can ruin the profitability of a company. I have to believe that Meade has lost money on me, because they've sold me three telescopes for the price of one. While they may be able to sell the first return at their outlet store (if they have one) after reconditioning or lubing, I don't think they can do that so easily on the second. Telescope 3) Mechanically, this is definitely in a different class than the other two. Everything seems to be working very smoothly and accurately, but I don't have a check on the optics. Last night it was quite cloudy, so I couldn't look at a star and had to make do with a porch light a quarter of a mile away -- not quite the same thing, but it did exhibit a clean collimation pattern. Tonight should be clear since Washington, DC seems to have dodged the big storm. I want to give a vote of thanks to the Discovery Store people. They honored (under a little protest) the old guarantee of The Nature Company, their predecessor in my area, and allowed me to trade in the original ETX-90 although not at full price ($595) but only at the price of today's ETX-90RA ($495), which I thought was more than fair on a three year old instrument.And additional:
More on the multiple ETX saga: Telescope 3) I still haven't had a chance to star test it; it's still daylight as I write. However, I have gone through the reset/calibrate/train routine and have poked around at terrestrial objects. Telescope 3 is definitely somewhat different mechanically than its predecessors. First, the 1/4 x 20 screws to cover the tripod holes are made of a slightly shinier plastic, and at a very subtle level the texture of the body plastic seems just a bit glossier. When you turn the DEC lock knob the pseudo-setting circle underneath rotates with it. Yes, with finger pressure you can stop that, but there seems to be something different about the mechanism. Also the M trademark seems to be under a more jewel-like bezel. Not _sure_ of that since I don't have the other to compare to it. But I am sure of the following: the motors are quieter except in fast slew and sound (slow slew) more like the ticking of a clock. There does seem to be less backlash to be taken up when you start a motion as well. Does anybody have any ideas whether or not Meade slipped in some running design mods and improvements? I don't think a reader of this list would recognize the differences unless he had been handling the instruments one after the other over a short time period. They are subtle, but all seem to be in the direction of better operation. We shall see.Mike here: The above is an update to an earlier email from Pete. In that earlier message he asked about an email address for Meade tech support. I responded with the following:
As to Meade not having an email address, well neither does Celestron (according to their web site). Neither does Intuit (a well-known software vendor) for technical support questions. So not having an email address is still not that unusual even as we approach the 21st Century and the 3rd Millennium.
Subject: A little info...if you have time. Sent: Saturday, December 30, 2000 09:21:32 From: email@example.com (Bill Humbert) I ran across your ETX site this morning. WOW! I'm impressed. I bought an ETX from Sams yesterday for $350.00. Specifically, the box says ETX Astro telescope Model M. It has a 90mm aperture and came with 9 and 25mm eyepieces. I think this is the predecessor to the ETX-90RA. Or is it the RA? Do you have any further information about the Model M? I set it up last night and enjoyed views of the moon and venus (I believe in half phase). But I have to admit I was a little disappointed. I expected more power and resolution. Of course, this is my first telescope so expectations were exagerrated I'm sure. Anyway, this morning I disassembled and packed it up (after painstaking borsight the finderscope) to return it. I then began looking for more information. I found your site and I think I've changed my mind. I guess I just need patience. In taking pictures with this ETX, should I always guide the scope? Also, how do you accurately guide with only a single axis drive motor? I'm suree I will have more questions later. For now, thanks for all the work. I will be at your site often. Maybe one day, I'll submit a photo or two. Best Regards and Happy New Year, Bill Humbert Ft Walton Beach, FLMike here: Since you are new to the site, I'll forgive you for not seeing all the comments that the Model M is the same as the original ETX Astro (now also called ETX-90RA). Once your expectations match the capabilities, you'll find that it is a fine telescope. Look through the Astrophotography Gallery pages for information and examples of what you can do. Guiding is only required for long duration photos and except for piggyback photography you really can't do long duration photography with the ETX-90RA.
Subject: Hello Again Sent: Friday, December 29, 2000 21:48:02 From: firstname.lastname@example.org (Ron McCafferty Jr) I recently bought a used 1987 vintage Celestron Super C8. I wasn't really planning on buying another scope but a friend of mine was getting out of astronomy and made me a deal I couldn't refuse. I did a side by side comparision to my ETX 90RA. I looked at Jupiter, Saturn, the Pleides, and the Orion nebula. The best analogy I can think of is the difference between adjusting your computer screen resolution between 640 and 1024 pixels. This is in light polluted conditions. The C8 is bigger and heavier but not really harder to set up. It is definately more stable but then again I'm using a heavy duty video tripod as my ETX mount. I want to do more comparisions but I left batteries, which corroded, in my ETX and had to send it to Meade for repair. I want to compare moon views. Having said all that I have NO plans on getting rid of my ETX. If I had to make a purchasing decision today on 2 new scopes and factored in money the ETX provides big bang for the buck. Ron
Subject: View Distances Sent: Friday, December 29, 2000 16:26:49 From: email@example.com (Ashley Dias) I have an ETX-90EC and I have been trying to learn how to use it and I don't understand how the telescope can see so far into space yet will only increase views only miles away when looking at objects on the ground. I have the standard eyepiece. I am just curious how that works, or am I overlooking something. ===== ___________ ! _____ ! ! ! ! ! ! !_____! ! !___/\/\/___! !!! !!!Mike here: For starters I suggest reading "How Telescopes Work" on the Meade web site: http://www.meade.com/support/telewrk.html. And then you need to know that stars are so far away that even with the largest telescope you CAN'T afford they remain as pinpoints.
Subject: date fonts Sent: Friday, December 29, 2000 10:37:36 From: firstname.lastname@example.org (Dean Schwartzenberg) I have noticed that the dates showing beside each new update, except the main page, have a weird, block style font. I really cannot even read them. This seems to have just started recently. Is it just my computer or a translation error from the Mac to PC? Thanks, Dean. Have you got your hands on a LX90 yet? They are great! Just like an etx on steroids.Mike here: I haven't changed any of the font stuff; just a font size="1" to make the dates slightly smaller than normal, except on the main page where it is size="2" for all the links and dates. It should be showing in your normal font face in your browser prefs.
Maybe that smaller size is whats messing up. I did have to completely reload this computer awhile ago and maybe my resolution settings are off, come to think of it, I do remember seeing this 'weird font' on some other stuff being e-mailed to me. It looks like we are getting several 'converts' from the nexstar group that have changed from the nexstar8 to the lx90 with lots of good things to say about it. Meade may have learned alot about new product introduction from all the ETX problems associated with rushing it to market. Maybe Meade will mistakenly send you back a LX90 instead of the 125?! Thanks, Dean.

Subject: ETX-90Ec and Super Plossl 9.7mm (4000 series) Sent: Friday, December 29, 2000 07:52:22 From: email@example.com (felch, richard) I received a ETX-90EC for Christmas. I went out and purchased a Super Plossl 9.7mm (4000 series) eyepiece. When I got home I found that it did not fit into my scope. Have you ever heard of this problem before? The 26mm lens that came with scope fit perfectly. Any thoughts? Rich FMike here: By not fitting I presume you mean that it could not be inserted into the eyepiece holder on top of your ETX. It should as long as it is the same 1.25-inch diameter as the included 26mm eyepiece. Check for some metal "burrs" on the eyepiece tube as some users have reported this; just carefully file them off.
There were no burrs, it looks like it was just "machined" to the wrong size. Thank you
Subject: Re: Guest Planet shots Sent: Thursday, December 28, 2000 21:14:12 From: firstname.lastname@example.org (Rick Krejci) I would find it hard to believe as well if I didn't actually do it myself. And just look at Jim Berry's web site...incredible stuff. I use his freeware capturing SW and I use freeware Astrostack for combining...both great programs. Like Mike said, luck plays a great part, as about 10 minutes after capturing that shot, my pics didn't look nearly as good. Also, hand-picking the nicest shots (out of 200!) help alot, but is very time consuming...I was seeing Jupiter in my sleep for a while. The key is quantity AND quality. The electric focuser is a REALLY nice accessory to have as well. I also had major troubles keeping the images into view until I went back to equatorial mount and the default controller. Much smoother and better control. I still get drift ( I don't spend much time aligning), but a small amount of drift actually makes for better shots, as it nullifies some noise. Rick

Subject: ETX 90 vs. ETX90EC Sent: Wednesday, December 27, 2000 10:50:52 From: email@example.com (Bill Walker) I bought an ETX90 (RA?) and the following year Meade released the ETX90EC. After 6 months of letter writing and phone calls Meade finally said there was no upgrade to the EC model, only buying the EC outright. They thought there might be someone in the Chicago area doing conversions. Bottom line is this: what can I do with my ETX90 to get it the capabilities of the Autostar system without having the EC drive base? Is there 3rd party hardware that I can use? Suggestions? Regards, Bill WalkerMike here: As has been pointed out on this ETX site since the ETX-90EC came out, there is no upgrade path from the original model ETX (ETX-90RA). Shutan (www.shutan.com) was doing trade-ins or you can sell the original and get a new one. There are some third party add-ons that can provide some of the capabilities of the EC models but you still won't be able to use the Autostar.
Subject: EXT-90EC Focusers Sent: Wednesday, December 27, 2000 10:01:19 From: CoghillTG@alyeska-pipeline.com (Coghill, Thomas G.) I live in colder climates and found that focusing my new EXT-90 EC can be painful without gloves (temperatures here -10 F to -40 F) and shaky (vibration) with or without gloves. What are your experiences with electronic focusers and has anyone come up with a fine adjustment knob for the EXT? I was thinking something like a piece of 24-inch surgical tubing with a larger disk at one end and the other end fitting over the existing knob. Has anyone done this? Does it work? Any suggestions would be greatly appreciated. Thanks in advance for your help and advice, TomMike here: There are several alternatives available: see the Accessories - Miscellaneous page on my ETX site as well as the Accessories - Showcase Products page for several focusing aids. Some users even attach a clothes pin to the knob; this provides better control at an extremely low cost (assuming you have a spare clothes pin around).
Thanks! I think the clothes pin idea is great. I can do that with gloves. I looked at your site and found another item that I can't live without. I will order it today (Dew Cap).

I find it hard to believe that one can get that level of resolution with an ETX90 and any CCD device, nevermind a low-res QuickCam. What do you think? PaulMike here: Combining images to improve the results is a standard technique. So, yes, with patience, luck, proper software, and reasonable shots to start with, you can get results like that.
Well, I am impressed! I can't even get jupiter to stay in the field of view long enough to get one immage with my SAC IVc!

I thought you might have a bit of advice for me...I noticed that you have experience taking Photo's with the "Ricoh RDC-4200 digital camera mounted using a Scopetronix Digital Camera Adapter) on an ETX-125EC". I am using the exact same setup (Ricoh 4200/ETX125/Scopetronix adapter) and I am having difficulty getting anything other than Moon shots, due to the camera's inability to hold the shutter open for long exposure times. Do you have any ideas? Maybe one can get adequate exposure of higher-magnitude objects like the Pleides (sp?) cluster or M43? There must be other things up there that one can snap photo's of, using that Ricoh digital camera, other than the Moon... Brian ___________________________________ Brian Leggee, Technical Director Responsive Technologies "Engineers Placing Engineers" San Diego, CA (760) 839-0400 firstname.lastname@example.org www.responsivetech.com ___________________________________Mike here: You can take digital camera photos of the brighter planets but nebula are beyond the reach of that Ricoh model (and most digital cameras as well). You can adjust the exposure level in the Ricoh's menu and you should use the self-timer to let vibrations dampened out.

Subject: my experiences with an ETX in England. Sent: Saturday, December 23, 2000 05:29:46 From: Garvinf@pollock83.fsnet.co.uk (Garvin Pollock) I saw an advert in a newspaper for a second-hand 4.in Meade Newtonian for 150.00. To cut a long story short I purchased it for 100.00 from an American who had bought it in California.I took it home and set it up.I found because of the wooden tripod it vibrated every time you touched it. The moon looked great but otherwise it was a waste of time.So I part exchanged it for a new ETX90RA this was before the EC came out.I was very happy with my 90 until I went to a Star night where I had a chance to look through a 8in LX200 .which I could not afford to buy .Decided to build a 6in Dobsonian as some one had given me a 8in Plastic tube 48ins long. This turned out to be one of the best 6in telescopes in the star club I had joined. The only trouble was carrying it around in the back of the car, because I had to recaimate it each time, and it weight half a ton.So I sold it and bought a second hand 7"LX200 .Known as a Mac 7. This gave me many enjoyable evenings, the only trouble was weight again. I even put it on a low steel platform with industrial castors. This worked quite well as I always kept my scopes in the garage so they were always cool enough to go straight out for viewing. I then heard about the ETX125 and thought this was the scope for me.It was the GOTO part I liked as I knew I would never be able to find M45 etc etc. I ordered one from the Meade main agents in London.UK. There was six months waiting list, so I borought a ETX90EC and had a lot of fun GOING to all the stars I could never find. It was then I came across this web sight and started reading about the problems you chaps in the USA were having with the 125, infact I nearly cancelled my order.It was then my 125 turned up and I part exchanged for the 90EC. Well gentlemen I experenced every type of fault you had written about.In the end I took it back and they exchanged it for a mark 2. I had the feeling that Meads had sent a batch over to England that had been sent back to them.7000 miles away ,out of sight out of mind. I was very happy with the 125 and it did every thing I wanted.the only trouble was the weight. I wanted to take it abroad with me. The Hard case was too large to carry onto an aircraft, and I did not want it to travel out of sight. So I purchesed a second hand ETX90EC and exchanged the 125 hard case for the 90.To crown it all I purchased a second hand LX50 tripod and the first time I used it with my 125 . I closed the up and over garage doors forgetting the tripod was 4ins higher. The door caught the 125 and knocked over smashing one of the side arms right off. I now have an ETX90EC on the LX50 tripod and the optics of the 125 which are still perfect thank god onto a Equatorial tripod. The best thing I bought was a electric focuser which gives me pin sharp views of the rings of Satan and the terraces inside the craters on the moon.I am waiting to see if my insurance company will pay up. I am not certain if I will buy an ETX125 ,at the moment I can travel any where with my 90, and the 125 is great in the back garden. One other item I can recommend is the computor program "Starry Night." Before I go out I always look at Starry night because it tells me what I can see and where all he planets etc are. One spooky thing happened with it. I put my self in Israel on the 20th of April 3AD at 14.00 hrs and there was a total eclipse of the sun for nearly three hrs. This was the day Christ was crucified???
Subject: Views Sent: Friday, December 22, 2000 22:10:23 From: email@example.com (Paul) Tried out my ETX 90 tonight. First, I tried out the star colimation test you suggested and I do see a concentric circle one way and a reasonably concentric circle the other way. When I looked at Saturn I could see rings quite easily but I can't even imagine how one could see a cassini division with the image resolution I was getting. With Jupitor, I was seeing a very bright almost solid white almost featureless mass with a suggestion of three bands. Four planets were quite obvious. The images really were not much different from some of the less impressive guest photos on your site, however I thought viewing the planets directly should give better resolution than astrophotography not a little less (I know deep sky objects are seen much better with astrophotography). Is this because many of the photos have been computor improved or do you think my resolution is not as good as it should be? Can you think of any other way I can test the scope to make sure all is well? Unfortunately, I've never used this scope before and I have nothing to compare to. Thanks again, PaulMike here: Keep in mind there are many variables when viewing astronomical objects. Atmospheric conditions ("seeing") can affect your views as can dirty optics. And then there are user expectations. On a good night you can see the Cassini Division in Saturn's Rings with the ETX-90 and the standard 26mm eyepiece. However, higher magnification makes this easier. Some of Jupiter's cloud bands are easily seen but as you note, there isn't much contrast in them. You can enhance the views by using certain filters (see the Accessories - Filters page). Again, good seeing and higher magnifications will help.

Subject: Can I ask one last question in 2000...? Sent: Thursday, December 21, 2000 13:50:19 From: MFRiesco@directvla.com (Riesco, Michael F) Dear all-knowing Mike -- Firstly, I REALLY appreciate your taking the time to answer questions -- you very kindly responded to an e-mail I sent you earlier this week (asking about the Meade 2x Barlow lens, Model 140). Can I trouble you with one more request for advice, and then I'll leave you to your Happy Holidays! I will shortly be getting an ETX-90EC, and my question is this: I know that the scope comes with a 26mm Super Plossl eyepiece, yielding 48X magnification. I want to invest in one more eyepiece (at least for now), to have the ability to go to higher magnifications. If you were going to recommend one more eyepiece, which would it be? I think I've narrowed it down to either the Meade 6.4mm Super Plossl (which would give me about 195X) or the Meade 9.7mm Super Plossl (which would give me about 128X). Obviously, each of these could be doubled with my Barlow lens. What is the "down-side" of going with the 6.4mm vs the 9.7mm? I would imagine that there is an optical "price to pay" for the higher magnification of the 6.4mm (vs. the 9.7mm) -- what is the tradeoff? Or, am I barking up the wrong tree with either of these 2 eyepieces, and if so, what type of eyepiece would you recommend? Again, thanks so much for your help. I promise no more e-mails from me for awhile!! Mike Riesco (email@example.com)Mike here: Glad to be able to help. Asking questions is good, whether I can answer them or let others answer them. That is why this ETX site became and remains so popular; we help each other out. In choosing between the 9.7 and the 6.4, personally I'd go for the 9.7 (which is what I did in 1996). Double-ing the 9.7mm is doable with the ETX on bright objects but doubling the 6.4 will likely not yield very good results. So, if you were to get the 6.4, in reality you'd only have three magnifications, not four, to work with.
Subject: ETX-90EC and Cold Weather Sent: Thursday, December 21, 2000 13:30:47 From: firstname.lastname@example.org (Jamie Hawley) I'm a complete newbie. I have absolutely no telescope experience... However, I have always been fascinated with the night sky. I started doing some research and came across your site. It is wonderful and very informative. I have been able to scratch the surface in understanding all the technical terms of this science. Through the info on your site I decided to purchase an ETX-90EC, Autostar and a couple of starter accessories (different Plossl and moon filter). Here's my question, we have a cottage in northern Wisconsin that we will be at between Christmas and New Years. It's freezing up there (single digits). I'd like to bring the scope and do some observing (learning) from the deck. Will I damage the scope using it in such cold conditions? Again Mike, thanks for the site, it's really helping me to decipher all of this technical jargon that is Greek to me. Best Regards, Jamie HawleyMike here: See my comments to the "Cold weather viewing" email further down this Feedback page.
Thanks a lot. I found the related post. I'll let the scope cool down gradually and the same with warming it back up. I'd hate to have to wait 'till spring to use the scope! It was brutal here last night -10, too cold! I hope it warms up a little by the time we get to the cottage.

Subject: Televue Starbeam on ETX Sent: Thursday, December 21, 2000 05:41:31 From: email@example.com (resident) I was curious if you knew of any way to mount a Televue Starbeam ( zero power finder ) to my ETX 90. I really find the finder to the best I've ever used in conjunction with my Televue refractor, and think it would make an excellent substitute for the existing finder on the ETX which is ( literally) a pain in the neck. Thanks for any assistance you may be able to offer! Seasons Greetings, GeoffreyMike here: Velcro, pads with glue, superglue, plastic cable ties, rubber bands (don't laugh; I use rubber bands to mount the Rigel Systems QuikFinder)?
Subject: new 'M' model at Sam's Sent: Wednesday, December 20, 2000 16:13:48 From: Lawmic@aol.com I'm not sure how fast you get a chance to respond but if you see this quick and can get back to me I'd appreciate it, as I'm under the gun looking for a Christmas gift for my daughter. I've become almost thoroughly confused trying to decide which model to buy and in fact right now have both a 70AT and a 60AT tucked away. I gave $314 for the 70 at Natural Wonders, so I got the nicer numerical autostar, but then I found a 60AT for $269 with a free tripod by mail. While I was ready to pay the $50 for the upgrade, this is now close to $145 when the free tripod is tossed in. Now I notice Sams has a ETX model M, that looks like an ETX 90 in disguise. It's going for $349. So now I'm really confused. I can pay an extra $100 for the Autostar and pick up a tripod later. Have you seen this Model M and if so what can you tell me about it? If there's any chance you can send me a direct reply to save me the hunt around your web sight I'd appreciate it. Thanks, LarryMike here: The ETX Model M is the same as the original ETX model (also now known as the ETX-90RA). It is NOT compatible with the Autostar and CAN NOT be upgraded to be compatible.
thanks for the quick reply
Subject: Barlow Lens Question Sent: Wednesday, December 20, 2000 14:54:38 From: MFRiesco@directvla.com (Riesco, Michael F) A quick (& hopefully not too dumb) question for you -- I plan to buy an ETX-90EC sometime next year. However, I just bought a Barlow lens for my son's small Celestron 60 mm refractor which, like the -90EC, accepts 1.25 inch eyepieces. The Barlow lens I bought is the Meade model 140, which is their more-expensive ($85) 2X apochromatic model, with a 1.25 inch diameter. My question is: will this lens be compatible with my future ETX-90EC? I ask because I read somewhere that the "short-focus" Barlows are well-suited for the -90EC, and this Barlow that I bought is NOT a "short-focus" lens. Thanks in advance for your response!! Mike Riesco (firstname.lastname@example.org)Mike here: I searched the site for "140" and found the answer to your question: it does work according to a report.

Subject: Purchased my ETX-90EC this week! Sent: Tuesday, December 19, 2000 21:02:01 From: SKBROTHERS@aol.com After pouring through the info. on your awesome sight I finally pulled the trigger and purchased an ETX 90EC from ehobbies! I'm impressed with the optics thus far but want to add a Barlow lens. Would you recommend the standard Meade 2x for about $40? I have also seen a 3X version, is this worthy of consideration? I want to maximize my investment and get the best Barlow available. I checked your eyepiece link but didn't find a comparison of Barlows. Is a Barlow a Barlow or is Meade, Celestron, or Televue optically superior? Thanks for your help! email@example.comMike here: I find a 2X Barlow worthwhile as it effectively doubles the number of eyepieces you have. Yes, you could get a 3X but that complicates things and with the ETX-90 model might be overkill. High optical quality is important in a Barlow Lens so don't get a cheap one. The #126 Barlow from Meade works well.
Subject: Meade ETX90 Question Sent: Tuesday, December 19, 2000 20:29:42 From: firstname.lastname@example.org (Spagnoli, Peter J (US - Parsippany)) Today I received by Meade ETX90 from astronomics.com. I have a question that I am hoping you can answer for me. I am new to astronomy but for the last several months I have been studying the sky with a star map and a pair of binoculars. My interest increased so I purchased the ETX90. However, now I am debating whether the $600 would have been better spent purchasing the Meade 4" refractor for $600. Can you please provide some guidance. I would really appreciate it. Thank you! PeterMike here: Aperture vs portability is always a key decision that must be made. Your decision depends upon how you want to use a telescope and what your expectations are.
My expectations are not drastically high.. I guess I am somewhat suspect of the long term reliability of the motors within the ETX90. I'm also questioning "how much better" would the 4" refractor be when compared to the ETX90. I'm curious.. you dedicated an entire website and a lot of your personal time to the ETX90. Why? What "sold" you on this scope?Mike here: As I state on the ETX site home page, I've had my original model ETX since September 1996. Its looks, size, capability, and price were what initially attracted me to it. After using it for a short while I found that its optical quality also made it a fine astronomical instrument, a "mighty" telescope for its size. I've never had any problem with its motor (it only has the original RA drive). From the success of the ETX line I guess I'm not alone in liking the ETX.

Subject: Telescope evaluation Sent: Tuesday, December 19, 2000 06:22:18 From: email@example.com (Copenhaver Thom) I currently have a Celestron 60mm refractor with an impossible-to-align finder scope. Other than the finder, I'm pleased with my current scope. I >>DO<< think that not having a good finder limits my star hopping. I have the opportunity to borrow and optionally purchase a used loaded Meade ETX-90EC (with Autostar, hard case, field tripod, several eyepieces, for $300). The guy who's selling got a bigger Celestron with GOTO for Christmas, and he doesn't need the ETX anymore. Here's the question: What should I look for (on the scope and in the sky) when considering a scope upgrade? For the couple of weeks that he's letting me borrow it, are there any particular DSO's that would be useful test cases for proving the value & quality of this scope? Are there any common issues to address when buying a used scope? Even without trying it out, I'm almost positive that I want this scope. I believe that the optics alone would be worth the money, and if the Autostar is easy to use, well, that's just great. However, it's always a bit of a commitment to get a new scope....

Hopefully you have time for one more. I had decided to purchase the 70AT as a nice big-boy's-toy for $349 and enjoy the auto-finding features -- Then, I'm walking thru Sam's, as if it was "meant to be" and see a Model M for $399 which I impulsively add to my cart. Now, I'm searching the Web to see what I got, but to no avail. Is the Model M is a discontinued item, and/or worthy of consideration? Also, if I stick with it, which I am now inclined to do, I will wonder forever how well any auto-find feature would have worked. Your thoughts ??

Your answering all my questions, except one. Here are all my facts: I have recently purchased the ETX125/motor drive/Autostar. I live in Michigan. It's REALLY cold here this time of year. I do have many years experience in photography, none with telescopes. Here is my question: What preventive maintenance should I do to the scope before taking it outside in the winter here? I'm sure that it will be anywhere from 0-20 degrees F next week when I plan on using it. Are there any possible ill effects for the telescope? Or should I not even take it outside in the winter? Hope I'm not out of line here writing in a question to you like this, Thanks for all your advice!!! Christopher D. SorgatzMike here: Cold temps are OK as long as you don't subject the telescope to a cold shock but taking it from a real hot indoor location to sub-zero temps. Try to let it cool down at a slow rate. Same for the reverse. Condensation might be a problem coming back inside so watch for that. The Autostar display may blank when it gets cold so try to keep it in a pocket when not actually using it. Battery life will go way down in the cold temps so AC may be a better choice.
I'll look forward to getting out next week and trying out the telescope.
Subject: Primary mirror shift while focusing ETX Sent: Sunday, December 17, 2000 20:18:03 From: email@example.com First of all, thanks for a great site. I hope you can help me with the problem I've got. (Or maybe I don't, who knows?) I have noticed the shift in the image when I turn the focusing knob on my ETX90. The supplier where I bought the scope claims that this is normal for a "Mak" because the primary mirror is being moved forwards and backwards. They also claim that a certain amount of movement is acceptable and that I should not worry about it. This is OK with a standard 26 mm eyepiece, but when I use a 6.3 mm eyepiece, the star I'm watching shifts significantly from side to side and sometimes gets out of the field completely. I am very careful during the focusing and I've got a flexible focuser, so that the vibrations are kept to a minimum. Have I got a faulty telescope? Or this is indeed normal... Please help. Thanks VedranMike here: I've never seen the image shift entirely out of the field of view when using a 9.7mm eyepiece + 2X Barlow Lens (effectively a 4.8mm eyepiece) on my ETX-90RA. But some shift is normal due to the design of the ETX.
Thanks, Mike! Should I contact Meade for this?Mike here: Wouldn't hurt. I'd be interested in their response.

Does Meade make a telescope that is that LARGE? or is that just a PhotoShop computer job? thanks Tim And what do you think is the best telescope for your money....if you had to pick one what model would it be??Mike here: As I have mentioned earlier on the site, the photo is edited to get across the idea that the ETX is a "mighty" telescope for its size. And yes, Meade makes LARGE telescopes, up to 16 inches, just not in the ETX line. Since I don't own every telescope in the world, I really can't say which telescope is the best for the money. I certainly would like to own an LX200 12" but I'll keep the ETX-90RA for now.

But there is a "sac-iv c" on their website that has a special feature : "The integration program now comes with auto tracking for the Meade LX200 line, ETX line and the DS line. This allows the camera to integrate a large number of images. It also allows you to use the SACIV for auto tracking when imaging with other brands of cameras that don't have auto tracking." <- (text from www.sac-imaging.com) The questions are now : a)Has anyone buyed the c-version of the sac-iv and tested this tracking - feature? b) What precision can i get (using a standard ETX-90EC/Autostar)? c) Will it work as an autoguider for a piggyback - mounted SLR (over more than the 1 - 4 minutes with possible with the autostar alone)? And, finally, d) is there a standalone - software that will do tracking with any (modified) USB - Webcam? (because sac-imaging won't sell the software without the cam. i've asked them.) Hey, thanks a lot for your great website. It's very helpful if you got an ETX (especially in germany :-)).

He should be commended, and I totally agree. However, without your site, Dick, Meade and myself would probably not exist. I commend you all for a very exciting and informative site to visit. What have I learned? Only about a billion things I never thought I'd ever need to know, but what fun it has been, and exciting because its all new and unexplained to we novices. The heavens are truly mysterious, and that make it all the more appealing. The International Space Station and its huge solar panels have even given some excitement to my wife. We've both seen satellites before,but none of them had humans onboard. This beast is awesome on a clear evening. Some good buddies of mine have flown in the shuttle (several times), but I never saw live pictures from space before like this last mission. Xmas time, which means I have to show of the scope. No problem, I did choose to go with Alt/Az because its lighter and easier to set up. But it has been almost too cold to use this beast, like -19 F That should put the ol Autostar to the test. Keep up the good work, more on cold temps later, Tony Bulat
Subject: ETX Model M Sent: Friday, December 15, 2000 15:12:40 From: email@example.com (Dave and Tracy McVicker) Which of your headings would direct me to information concerning the scope I have? The ETX 90 Model M (Manual). I have enjoyed perusing your wonderful sight. It will definitely be a favorite.Mike here: The ETX-90M is the same as the original model ETX released in 1996. It is also known as the ETX-90RA. See the "User Feedback" page for user comments.
Subject: Meade 4504 & Starfinder 494 (yes 494) Sent: Friday, December 15, 2000 00:57:08 From: firstname.lastname@example.org (Wayne Scharphorn) Hi Mike..great site, thanx Meade Customer support tells me the handcontroller supplied with my model 4504 is a #494 Starfinder model of the Autostar (no numeric pad,otherwise it looks like the 497 or 495).. When it initializes it flashes "c Meade [1.0] STARFINDER" and requests date..time..etc. Do you know if this can be updated? I've looked on your site and Meade's but can't seem to find any info specific to Starfinder or #494..Meade is vague in my request for info but they did say this model can be updated and requires a #506 cable set but wouldn't be more specific...?? Thanx for any help you may offer Wayne P.S. Someone asked in the feedback section of your site if the drives could be put in "neutral"... on my Starfinder if it is tracking and I push "Enter" for about 2 sec. it beeps, the drives stop and the display reads "enter to sync"; the drives only start tracking again after pressing "enter". I have no idea if this "feature" is specific to my model.
Subject: Re: HI Mike Sent: Thursday, December 14, 2000 19:55:19 From: Misterjingle@aol.com Thanks for the replay and the information. So would you say if a person was to make the jump that he should to the ETX 125 then? By the way I have read alot of what people had to say about all the ETX models....Your site has theBest information on the Web forsure! Thanks, CraigMike here: It depends on how you will use it and what your expectations are. Check the recent Feedback pages; I've answered this question a lot in the past couple of days.
And a response:
Oh yes, I understand Mike.....Thanks for having a great web page. I've decide that I'm going for the Meade 125, If I feel I love looking at the stars! thanks again!
Subject: ETX Sent: Thursday, December 14, 2000 07:06:00 From: DuchyDog@aol.com Saw you web site so I thought I would write. I just received my first telescope which is an ETX-90EC with the Autostart controller. In fact, I have yet to open the box. Should I try an upgrade to the 125 while it's still brand new? Is it worth the difference? My uses are basically unknown since this is my first telescope. Thanks, GaryMike here: The extra aperture of the 5" is nice and noticeable (for smaller and/or fainter objects), if you can handle the decrease in portability (although the 5" is still generally portable). The ETX-90EC makes a fine first and last telescope. But you really need to decide how you want to use the telescope.
Subject: Buying an ETX. Sent: Wednesday, December 13, 2000 16:41:05 From: email@example.com You asked that I let you know about my progress in buying my first telescope, so I'll tell you. It is painful. I live near Princeton, NJ. The University has a public viewing night where I hoped to do a little viewing & make contact with other amateurs & get some local advice. Unfortunately the weather has not cooperated and the last two sessions have been cancelled. The ETX series appeals to me because I live in a small valley with tall trees all around. Any real viewing means putting the scope in the car & driving up to some nearby fields. Portability is important. I also visit family on the Eastern shore, & taking it there should be very rewarding. I like the idea of the Autostar because it will allow me to see a lot of identifiable objects rather than "points of light." & speed a learning process that probably should have started many years ago. The best thing about the ETX is your website, because it's been the only source of "real world" info on the ETX. Trying to find an ETX 90 or 125 isn't easy. Most stores are out of one or the other, and I had hoped to compare them side-by-side. One store had only and ETX-90, and they wouldn't even take it out of the box to let me look at it! Tonight I found a "Knowledge Store" nearby that said that they had both in stock, so there I went. The 90 was on a tripod & the 125 was under a plexiglass box that they would not remove. Nobody in the store had the faintest idea how either of them worked or could answer any questions. Because of lessons learned from your website comments, I wanted to know if the unit needed warranty repair it could be exchanged there or if I would have to send it back to Meade - blank stares for a while, then a suggestion that I exchange it under their "gift receipt" program within 30 days. After some fiddling, I could slew the 90 up,down, left, & right, but since the farthest object was @ 75 feet away there wasn't much to learn from looking through it. If you were my friendly, local telescope salesperson I'd discuss the following: I'm 54 years old with several daytime & summer pastimes. One month ago I had my first look through a telescope (a 4" Meade Refractor) & saw 4 of Jupiter's moons, plus a very good look at our moon. I want to see more. I hope to see a lot and keep note of what I see, but have never had much interest in photography. Portability is important, as well as a wish to avoid a maintenance headache. Some questions: 1. I don't mind spending money, but I hate to waste it. For someone who probably won't advance beyond the hobbyist level, will the 125 provide noticably better views and/or offer a qualitative advantage over the 90? Simply put, is the cost delta worth it? 2. I read the Sky & Telescope comparison of the Celestron & Meade 5" M-Cs, & it seemed that the things that are important to me favored the Meade, but I'd like to hear your comments. 3. Since there seems to be no value in buying from a local store, which mail order house will be the most helpful if I need service? 4. For either model that you would recommend, what accessories are essential for the first few sessions? Since it appears that the first time I will be looking through either scope will be after I own it, I thank you in advance for your answers to these questions, and any other suggestions that you might make. Bob ThompsonMike here: Sorry you had some rough experiences. Fortunately, not all dealers are like that but there are probably more than there should be... At any rate, the extra aperture of the 5" is nice and noticeable (for smaller and/or fainter objects), if you can handle the decrease in portability (although the 5" is still generally portable). I have some realworld comparisons of the NexStar5, C-5, and ETX-90EC and ETX-125EC linked from the top of the current ETX-125EC Feedback page. Mail order dealers frequently mentioned on this site as good include Oceanside, Scopetronix, and Shutan. Others are mentioned, just not as frequently or vocally. As to accessories, check the Buyer/New User Tips page for some thoughts. A 2X Barlow Lens is a good first accessory since it essentially doubles the number of eyepieces you have. As you add more eyepieces, you can continue to double the number.
Don't know how I missed this page (the comparisons), but it was just what I wanted. Thanks. The 125 it is.

Subject: RE: Digital Camera Sent: Wednesday, December 13, 2000 06:13:08 From: GSkoubis@ussco.com (Skoubis, George) Thanks Mike! I think I'm going to go with a "multi-use" digital camera for the money I will spend. George
Subject: Digital Camera Sent: Tuesday, December 12, 2000 07:28:38 From: GSkoubis@ussco.com (Skoubis, George) I'm looking for a digital camera for astrophotography. The first that came to mind was the SBIG ST-4. Have you heard anything on this performing well with the ETX 90? Does it have enough light gathering capabilities for some of these nice ST-4 pictures (one-hour exposures) I've seen. If I can't really find feedback on this, I was going to purchase a regular digital camera and use it for taking regular images as well. Thanks in advance -GeorgeMike here: It will be a challenge to track for hour exposures. Other than that and the expense of the ST-4, it should work.
Subject: digital cameras Sent: Monday, December 11, 2000 21:55:39 From: email@example.com (Tony Bulat) If you had all the money in the world and you wanted to purchase the best digital camera that was compatible with the ETX-125 with a #64 T- adapter, and the T-ring adapter and the basics 1.25" camera adapter, what would you buy? Kinda putting you on the spot,I know, but I feel there's a lot of confusion out there and some of your guest astrophotographs try to explain what they shot and how they shot it, but put it in terms that are really hard to decipher. Seems there is a bunch of good stuff available on the market, but digital cameras that don't allow a person to change focus, F-stop, and exposure time are a waste of time. Zoom capability is one of those things that doesn't interest me in the slightest. Prime Focus or Eyepiece Projection with a digital camera seems far superior to A-Focal projection. Am I wrong? The beauty of a digital camera is it's ability to take several shots over a short period of time, and then stack the results and play with them as one sees fit to make the photo look better through enhancement. That's very enticing since my old SLR is even older than yours. A Cannon Pellix circa 1970 with non-movable mirror. Good ol buddy takes some damn good pics, got combat photos to prove that, including some friends of yours if I wasn't so lazy to dig them out You take care and check six good buddy, Tony BulatMike here: Since I don't (currently) have all the money in the world (the Pledges haven't been THAT forthcoming, at least not yet...), I haven't done all the research necessary to formulate any opinion. To do what you want will require a digital camera with a removable lens OR you can purchase one the new "digital film packs" that replace a 35mm film can with a CCD at the focal plane. The last time I read about them they were about $1000 for a 12-shot version. You'd then need a 35mm camera with a removable lens.
Thanks for the info, as usual. I do have just such a camera, the trusty old Cannon Pellix with the famous bayonet. You sparked my interest with the "digital film packs". I had not heard of that option before, even though C-Net sends me all kinds of stuff on digital equipment. One of your readers just recently mentioned the "Olympus C-3000" that has a threaded lens barrel that permits direct mounting to the scope via a T-ring adapter. Sears has these for about $585.00 vs. $799.00 regular price. Makes me nervous, but this is the kind of critter I think I'm looking for since all my other Camera accessories would also work. BTW, the info on the Olympus was posted either on the 10th or 6th of Dec. I'll check it out some more, meantime have a Merry Merry Christmas. Tony Bulat P.S. Having fun looking at the ISS every night since the solar panels were deployed. It's been a while since I've observed a satellite in orbit, let alone one with humans on board. Cool.

Subject: etx90 Sent: Sunday, December 10, 2000 19:28:32 From: firstname.lastname@example.org (Dave Stevens) Hi thanks for the web site, im a 1yr. owner of a etx90 astro scope, all that i can see is the moon and a tiny saturn and jupiter. i was told that i could see other galaxies and other nebulas etc., what do i need to buy too see these things. when i do look at other stars its just blobs of unfocused light. please help. thanks! daveMike here: You didn't indicate if you have more than just the standard 26mm eyepiece that Meade supplies with the ETX Astro scope. Stars, like the Moon and planets, should appear in focus, assuming that you can focus on the Moon and planets. If you can't get these in focus, you may have to reposition the focus knob a little further out on the focus shaft. You can see galaxies and nebulae but you have to know where they are (you need some astro charts) and you need to realize that most will appear as faint fuzzy blobs. Some, like M42 or M57, will have distinct shapes. Also, trying for maximum magnification is not always what is needed, especially on faint objects.
Subject: ETX question Sent: Sunday, December 10, 2000 18:38:12 From: David.P.Morley@Hitchcock.ORG (David P. Morley) Just discovered your ETX website--it's terrific! I have an ETX 90/EC. Looking at the opening pix on your website, I wondered what exactly you have threaded on the rear cell (flip mirror port) of your ETX. Could you just explain what accessories you have added to your scope?? Looking at your pix suggested to me that possibly I could attach a high power eyepiece to the rear cell of the ETX and at the same time keep the normal 26mm eyepiece in it's normal right angle position--thus being able to flip back and forth from high power to low power without having to be changing lenses in the dark. Is this possible? If so, what parts would I need? Any help you can render will be greatly appreciated. DaveMike here: That device at the rear port is the "Shutan Wide-Field Adapter", described on the Accessories - Showcase Products page. Full details on this page. And yes, I do the same thing of keeping an eyepiece at each port.
Subject: newbie needs help with a meade purchase Sent: Sunday, December 10, 2000 14:26:27 From: email@example.com (Nathan Smyth) I know you are probably very busy, but if you have a minute, could you help a newbie? I am looking at three entry level models: Meade DS-127, ~$500, 127mm, ~350X Max Meade ETX-90 EC, ~$600, 90mm, ? 350 Max ? Meade ETX-125 EC, ~$900, 125mm, ? Max ? I guess I have three questions: 1) If you had it all to do over again, would you go with Meade, or with another company? (Does someone else have a clearly superior product in this price range?) 2) Which gives a better view: the traditional long tubes (DS-Series) or the newer short tubes (ETX-series)? 3) Is the ETX-125 worth the extra $300 over the ETX-90? (Is it clearly superior?) Thanks!!! Nathan Smyth firstname.lastname@example.orgMike here: 1. If I were to do it over again I see no reason to not still pick the ETX-90 model. For the money, I think it is the perfect scope to match MY needs. You needs and expectations may require a different scope. 2. Depends upon what you expect to see. Contrast is higher on the ETX model due to its optical design. That is good on planets. 3. Aperture is good, but for some people (me included) portability is also good. Again, it depends on how you plan to use your telescope.
Subject: Dear Mike! Sent: Sunday, December 10, 2000 11:21:26 From: email@example.com (Billy) I recently bought an ETX 90-RA. I am a "newbie" and have very little knowlege of anything. Last night I was looking at Jupiter and Saturn (b/c those are the only two objects I know besides the moon 8-) and my problem is that I was having a problem focusing! It was soo difficult to get the image crisp! (actually, it took me a long long time to get it crisp on saturn). I own a refractor (piece of crap 60mm) and i had better focus than this!(well, maybe a little exaggeration there) I just bought it and so I dont understand..am I doing something wrong?? I focus on it, and its just not crisp and clear as the reviews Ive read say I would get from this scope. Some of the reviews I've read are from Sky and Telescope etc. Thank you for your time.. Bill TerrellMike here: Sorry you are having a problem. You didn't indicate whether this was a new or used ETX-90RA. If used, there are several possibilities. If new, there are some possibilities. In either case, there is one thing you can easily do IF there is not enough travel in the focus shaft. If the knob reaches the back plate on the ETX, then point the ETX upwards (to keep the focus shaft from falling inside the tube), loosen the small setscrew on the side of the focus knob, slide the knob a little further out on the shaft, and then retighten the screw. Try focusing again. Repeat if it appears that this is correcting the problem. If this is NOT the problem, do the star test described on the "Purchasing a Used Telescope" (linked from the Buyer/New User Tips page. If this is a used telescope you may have to adjust the collimation ("Collimating an ETX Mak" on the Tech Tips page).
Thanks for your quick response. I just bought this new ETX 90 RA a couple of days ago. I tried it out for the first time last night. My problem is not having enough room on the focus shaft to focus. My problem is just that it was EXTREMELY difficult to get objects in sharp focus. I could get objects in a pretty close focus. But at the slightest turn of the focus nob it would go from one side of really close to the other side of really close..but not right on the money focus. for a slight instant i might see it focused but it would shoot right past it as i slightly turned the focus nob. I've seen @ scopetronix taht i could buy a larger focus nob, would that help? I also noticed something else. When I would go to focus an object...it moved the scope sligtly. The blob of light would be right in the center of view, but as i focused it moved the scope, which means as im focusing I would have to use my ra nob to keep it in view. Im thinking about buying the flexi-focus..in hopes that the larger nob might allow me to focus easier. If you think that would help let me know. I dont think its out of collimation..but then again..it might be slightly. the moon was full last night(i think 8-) and it looked real sharp in my 25mm lens. When i move to my 9mm...its much harder to focus finely. Thanks for your help.Mike here: OK, we've ruled out the knob-shaft problem. It now sounds like you are just having difficulty reaching a fine focus. This can be due to the small knob, atmospheric turbulence, unstable mounting, and a lack of patience when focusing. A larger knob (including the "clothes pin" trick) can help as can the Flexifocus or electric focusers. Of course, patience (letting the hand-induced vibrations settle down) or waiting for better "seeing" conditions may also be required.
Subject: Quick Telescope Question Sent: Saturday, December 9, 2000 23:08:56 From: nitro5955@Home.com (Mike Fawcett) I'm not to knowledgeable about telescopes but I wanted to ask you a quick question. My wife has a Bushnell 340X60 telescope and I am looking at getting her a better telescope. I was looking at the Meade ETX-60 or 70 but not sure if it will be much better. If you could be me some good ideas on some telescopes I would greatly appreciate it. Thanks for you help, Mike FawcettMike here: Well, it might be a "quick question" but it does not and should not have a quick answer. Do your research (as I've said to others on this site). But to begin to address your question, the ETX-60AT and ETX-70AT make a fine beginner's instrument. The only question is whether your family will outgrow its limited capabilities. The ETX-90EC also makes a fine beginner's instrument, and it is one that you may end up keeping for life. However, if your visual expectations are grander you might want to consider the ETX-125EC (or other larger telescopes, perhaps even Dobsonians).
Subject: Starfinders and rs232 cables... Sent: Saturday, December 9, 2000 22:40:08 From: firstname.lastname@example.org (richard seymour) To: email@example.com The big question (since i've never seen a Starfinder) is: does it have an rs232 port? Or does it simply have the AUX port like the ETX60/at? IF the latter, then you need a #506 cable/converter set, and the simple build-it-yourself #505 clone WILL NOT WORK. The 506 has active electronics (left out of the 494 Autostar) to convert rs232 to i2c bus signals. It's not just a set of wires. --dick

Subject: Looking to buy a telescope Sent: Saturday, December 9, 2000 06:41:42 From: firstname.lastname@example.org (David Blyth) It looks like you're the man to talk to on the internet when it comes to the Meade ETX-90 telescope. I recently sent an e-mail to a retailer here in the UK but I wasn't entirely convinced with their response after having looked at your website. Here's what I want to do. I have a sony PC5E digital camcorder, this is very small (smallest in the world) and very light, it can also take digital stills. Rather then looking through the eye-piece all the time I want to take the DV or SVHS link from the camera and feed that into either the capture card on my PC or TV monitor. When I see an image I like I can then either capture a photo from the DV output, via the memory stick or the cameras RS232 port. I also want to be able to control the telescope from my computer to be able to point-and-click on a star and have the telescope automatically orientate itself. The UK retailer (http://www.sherwoods-photo.com) had some positive & negative comments about what I was trying to do, here are some of the comments. >The ETX would be the best contender at 549.00 but I feel that putting a >camcorder on the back is going to cause you two problems. Firstly the size >of the cameras is going to foul the mount when looking near vertical and >the other is the weight, the scope is not really designed for continuous use >with a camera strapped to it. This may cause problems with motor strain. >In theory the scope can be used to point and aim using a PC with software >packages such as Sky Map Pro 7 etc but for your type of 'arm chair >observing' it is not going to be possible with the budget in question. >You would need to look at something like a Meade LX200 (or LX50 if you can >find one with a Magellan II) range of scope which are considerably more >expensive but do have the advantage of better tracking and more clearance. Do you think he's right? Can't the vertical viewing problem be solved with a stand? Did I see something on your website that put the base of the ETX at a 45degree angle? And is 'arm chair observing' such a bad thing. I've just started to get my 2 year old daughter interested in using the computer, already she loves looking at the stars and moon. If I can combine the two, she'd love it. Looking at your website you seem to be putting quite a lot of weight onto the ETX. In one case I saw a second telescope and a large camera with telephoto lens all mounted on the one ETX, did you experience motor problems with this? The LX200 is way out of my price range, although it looks very impressive and it would appear to give the clearance for vertical viewing The Sony PC5 only weighs 0.5Kg (1 lb 2oz), so I would have thought the lens attachment could hold the weight of the camera. If I'm wrong do you have any thoughts on how best to attach it (its 25mm). I hope you can help regards David Blyth Horsham West Sussex EnglandMike here: What you want to do IS possible with the ETX-90EC. But there are challenges and limitations that you'll have to understand going into this. The dealer's comments are valid. Extra weight can cause problems; that "dual ETX" you saw had drive slippage in some orientations. As to extra clearance, there are two solutions: yes, you can use an equatorial wedge to potentially avoid the clearance issue when pointing near the zenith. You can also just mount the camera at the normal eyepiece position on top of the ETX. The Autostar can not easily recover from drive slippage (due to the extra weight) so once slippage occurs the pointing accuracy (from your computer) will be degraded. As to an adapter that might work for you, see the "LE-Adapter" described on the Accessories - Astrophotography page. Finally, you should consider whether this camera-computer-telescope combination will meet your expectations. Once you have everything working, viewing the Moon and the brigher planets will likely be OK. But do you want to observe fainter objects this way? If so, your expectations may exceed the capabilities of the small aperture when combined with the video camera. If you do pursue this, let us know the results (positive or negative).
Thankyou for responding, I feel more confidant about preceeding. The LE Adapter is quite expensive so I'll try and shop around a little first. I won't have the money I need for the whole setup until April, so I have plenty of time to study and learn about all the things I need to know. Does using a camera mean that you can't view the sky with maximum magnification?Mike here: There are two methods to using a camera with a telescope: prime focus and eyepiece projection (or afocal photography). Prime focus images the object directly onto the film (CCD) plane. There is no eyepiece or camera lens involved (the telescope acts as a telephoto lens). If you use an eyepiece then you can get various magnifications (with or without the camera lens still attached). Note that higher magnifications mean smaller field of view on the film (CCD) and that you will need a very steady mounting to avoid vibrations.
Now I know how my trainees feel when I'm teaching then about control systems for the first time. Can you recommend some books that can teach me the basics from scratch. Assume I know very little about photography as well as telescopes. Hopefully theres one nice book that will get me started to build the 'pc-telescope-digcam' system. I think I'll get more from your web site once I understand the application and all the jargon a bit better. Thanks again.Mike here: See the Book Reviews page on my ETX site for some info. Couple of books you might want to consider:

NASA has a nice Java applet called Skywatch which will tell you when it can be seen: http://spaceflight.nasa.gov/realdata/sightings/ Not just the ISS but other objects too. A while back I tried to track (manually) an ISS transit with my ETX-125EC. I could keep it in the finder but it moved way too fast to get it in the EP! I guess theoretically the AutoStar should be able to track it if you can get it in view fast enough. Steve

Subject: ETX Astro help Sent: Friday, December 8, 2000 10:08:58 From: Thom_Tarter@usairways.com (Thom Tarter) First let me congratulate you on a very nice site dedicated to the Meade ETX family. Right before the ETX 90/EC was introduced, your site contained some technical "suggestions" about modifying the Astro for better performance. Things like teflon pads in the drive base, a power light, etc. I was wondering if you might still have some of that information as I do not plan to purchase an EC anytime soon and would like to make some of those mods to my Astro. Also, can you recommend a book on astrophotography? I plan to catch the Christmas partial eclipse. Any help you can provide would be greatly appreciated. Sincerely, Thomas TarterMike here: All of the past information is still online. Search for "teflon" and you'll get lots of hits. As to a good book on astrophotography, there are many good ones. Browse the your favorite book dealer. Get one that has info on the type of astrophotography you plan to do. As to the solar eclipse on 25 December, be certain you use PROPER PROTECTION, both for your eyes and your equipment.
Subject: Dealers Specials Sent: Thursday, December 7, 2000 21:35:05 From: firstname.lastname@example.org (Dan Schmitz) Are you ready for astrophotography and digital imaging in general? Now is the time to act. After weeks of homework on the web I settled for the Olympus C-3000 digital camera and the Epson Stylus Photo 870. The camera has superb optics, a zillion features including a remote (no shutter shake), is so lite the scope barely knows its there, and a threaded lens barrel that permits direct mounting to the scope via t-ring. The printer just can't be beat for print quality. Now for the DEAL. Sears has a price matching policy that applies to web prices also!! Result, $799.00 camera for $585.00, and I don't have to deal with those questionable merchants in Northeast. (if you've tried those discount sites in NY and NJ you know of what I speak.) First camera had minor flaw, back to Sears, exchanged, no problem. The printer, normally $299.00, now can be had for $249.00. And if thats not enough, if you purchase that model printer and ANY digital camera between now and Dec 31 you qualify for a $50.00 rebate. ($100.00 if you opt for the Stylus Photo 875DC, normally $349.00) Lets see, total savings of over $300.00,,,,with that its time for a larger memory card , case, lens extention, filters and t-rings with $$ left over. Just dosn't seem fair.(But I won't lose any sleep over it) See you soon in the Guest photo zone,,,clear skys
Subject: ETX-90 EC Sent: Thursday, December 7, 2000 07:34:05 From: email@example.com (Leo Eastham) Contemplating purchase of above tele, any suggestions on where i could get the best deal on one? Thanx, leoMike here: As I've noted many times on the ETX site, deals are hard to come by since the ETX is so popular. However, watch for sales or other events where there might be discounting. Sometimes I hear from users who see such sales and I post them on the Feedback page. I've also started a new "Dealer Specials" page, which hopefully dealers will use.
Thanx for quick response. I saw the etx-90 mc at sam's for $399 but I'm looking for the ec. Leo

Sent: Thursday, December 7, 2000 07:12:23 From: firstname.lastname@example.org (Eric Ball) Yes, I realised after further study of the manual that the R.A. dial needs to be adjustable separate to the R.A. axis - oops! I'm busy looking at the information on your site re Autostar cables, my Starfinder control panel has only four 'cursor' direction keys, a 'enter', 'mode', 'goto', 'up' and 'down' arrow keys along with a 'speed/?' key. it has a full goto ability with some 1400 internal coordinates. It would appear that if I follow the instruction re interface cable I should be able to guide the telescope from my laptop's RS232 port using proprietary software supporting ETX or LX telescopes.

Subject: re: slipping RA circles on 4504's Sent: Wednesday, December 6, 2000 21:24:53 From: firstname.lastname@example.org (richard seymour) To: email@example.com Hi... I saw your question on Mike's site. My ETX-90 also has (slightly) slipping circles... especially when the cords drag them along... My solution? a small piece of blue masking tape to hold the circle fixed against the moving part of the scope. You point the scope at a known target of known RA, Line up the target's RA number on the scale to the fixed pointer on the 4504's base, and then apply the masking tape so that the motor-driven part of the scope drags the RA scale with it. have fun --dick
Subject: RE: 4504 site? Sent: Wednesday, December 6, 2000 13:11:33 From: firstname.lastname@example.org (Eric Ball) Thanks for the reply, it's appreciated - you must get hundreds! Is Autostar a 'grown up' version of Starfinder? Incidentally perhaps you could help me. I received my Meade 4504 yesterday and upon assembling it this evening I note the R.A. setting circle calibration ring moves independently of the axis, in other words when I rotate the telescope around that axis the calibration ring either remains stationary or moves fitfully as it sometimes gets carried along by the axis - surely this can't be right?? All assistance gratefully accepted :) Eric Eric Ball tel +44 (0)1952 813558 cell +44 (0)7884 468272 E-mail email@example.comMike here: Yep, I do get a bunch of email. I don't know if I would call the Autostar a grown up version of the Starfinder (I don't have one). But certainly it is a capable system. As to your RA setting circles, they are probably designed to be adjusted (set to a known RA) at the start of a session and then it should stay "calibrated" as the scope is moved in RA. This allows you to locate objects by RA by moving the scope until the RA setting matches the object desired.

Subject: International Space Station Sent: Tuesday, December 5, 2000 12:00:55 From: firstname.lastname@example.org (David Langham) First of all, I understand that your site is dedicated to use of ETX telescopes, which I am proud to say that I own an ETX-90. However, I was hoping that you might have some knowledge about viewing the International Space Station. I have read that as soon as they are finished extending the solar panels, the space station will be one of the brightest objects in the sky. Anyway, I have gone to NASA's and the Discovery Channel's websites and all they show is a "picture" of where the station is. Do you know of any websites that would offer exact location coordinates (declination,etc.) of the space station? I wonder if Meade would have information like this that could be downloaded into the Autostar such as many satellites are? Well, thanks for considering this question.Mike here: Visit the Heavens-Above web site. It has predictions for your location.
Subject: Telescopes Sent: Tuesday, December 5, 2000 09:56:19 From: Joseph.A.Meschino@dupontpharma.com (Joseph A Meschino) I hate to do homework before buying anything. So before I make a bad mistake in the purchase of a telescope could you kindly take a couple of minutes to guide me on the following: I would like an instrument that - can be used for celestial as well as land viewing - is for amateur use - is reasonably simple to use - is in the $500 to 1200 price range I have been looking at the Celestron 114 GT and NexStar 5 I have not looked at any of the Meade ETX instruments. What do you advise? Thanks. JoeMike here: I advise: do your homework. You'll be happier with your decision, or at least understand why your made your decision. Know your requirements and expectations before hand. Browse through my ETX site for lots of comments on the ETX line.
Thanks for the sage advice.
Subject: Foam Sent: Monday, December 4, 2000 19:58:26 From: email@example.com (Tommy Connell) Nice site! I have not been here until I got an ETX90Ec for my son for this Christmas and found out about your site. It's been a great help. I have an LX-200 8" myself and got the ETX for him as he wants to look at things every time he and his family come down here from Athens, GA. Now, my question for you is, do you know of a good place to get good quality foam to line cases with. I have a couple of old aluminum Haliburton camera cases that I want to make into eye piece cases and accessory cases. It seems to me that I say either here on your site or on the MAPUG site someone making the comment that they had found a good source for the foam sheets in like 1 and 2 inch thicknesses, but I have done a search on both sites and haven't come up with anything. If you remember something about this, I would like to get the info from you. Thanks a bunch, and God Bless to you and yours on this great Christmas season.

Subject: tiny etx mods Sent: Monday, December 4, 2000 19:06:52 From: firstname.lastname@example.org Greetings, I have tried several of the modifications on this site; now it's my turn to contribute. I painted the small RA and Dec indicator triangles with white enamel. (Black triangle on black case, at night...) I cut a narrow (2 or 3 mm) strip from a self-adhesive mailing label. I stuck this on the top of the OTA as a front "gunsight". By sighting over the eyepiece, I can aim quickly and accurately. YMMV. I used an adhesive sticker instead of paint so I could adjust the mark later. I now want to add sighting marks on the sides of the tube for adjusting declination by eye. I later touched up the triangles with some glow-in-the-dark paint, but it really didn't seem to make much difference. Gloss white model enamel shows up nicely in the light of a red flashlight. I bought one of those little stick-on clocks and set it to UT. It came with a velcro pad. I stuck bits of complementary velcro on my tripod. Now I can stick the clock to a convenient surface, depending on where in the sky I am looking. When I made a dewshield from craft foam ( $0.99 ) and self-adhesive velcro patches ($1.49), I had some left-over foam. I made an itty-bitty dewshield for the front of the finderscope. This last is not my idea, but I tried it: hang a sheet of red acetate over your computer monitor. You can still use sky software (even when it claims to be in "dark" mode) and not fry your dark-adaptation. dark skies, Robert Lane
Subject: ETX-90-EC Sent: Monday, December 4, 2000 13:58:48 From: email@example.com (terry) HELP! I live in the u.K. Europe, and i am interested in buying an etx 90 ec from the states. I have seen one advertised at telescopes for less for 595.00 Dollars.

TERRY AND PAULINEMike here: Check the UK dealers listed on the Astronomy Links page.
I was interested in buying one from the usa. They charge too much for everything in the uk. Sorry you were not able to advise as to who would be the best to buy from.

Subject: ETX Question Sent: Monday, December 4, 2000 13:57:14 From: WJAlspaugh@aol.com Sam's Club is selling an Meade telescope package designated as ETX 90RA-M and including some kind of auto-tracking motor drive and a "$79.00 value" Sky Software Package. Their price is $399.00. Do you think this is a good deal, or should I look at the more expensive ETX 90EC instead? Thanks a lot. I love your website. Jack Alspaugh WJAlspugh@aol.comMike here: This is the original ETX model. It does not accept the Autostar and there is no upgrade path other than selling the old one and getting an EC. Both are excellent first telescopes. The original price was $499, then it was raised to $599, so $400 sounds OK.

It really is one of the best sites I have had the pleasure of Bookmarking. I am a "Newbie" and I have recently obtained a used 90 RA with tripod. I live in Canada so I have had limited use of it lately. I also am stuck on afternoons the last two weeks but I still couldn't resist looking at Saturn at 04:30 in -8 celcius weather. I was amazed that I could see the rings, I was using the standard 26 Plossel but I could still make out the rings. I can't wait until the weather warms up so I can spend more time in the backyard. I also have a cheap 2X multiplier, could you recommend a good next lens to purchase.

Subject: Question regarding the Solar filter in Astronomy magazine (User Feedback 11/29) Sent: Sunday, December 3, 2000 22:21:43 From: email@example.com (Dave Rounds) This is in regard to the comments in your User Feedback 11/29/2000. Apparently there must be two different versions of the December Astronomy magazine. The copy on the newstands in southern Wisconsin have red/blue "3-D" glasses. I did not find any references to solar glasses, although I did see some info on the partial solar eclipse. DaveAdded later:
I got my own answer to my inquiry...one of the guys I work with also told me about the eclipse glasses today. I usually buy the magazine in the local Wal-Mart around the middle of the month and did not realize that the new issue (i.e., January, in this case) actually comes out almost a month early. Our local store was still selling the December issue when I checked on Saturday. Now today, Tuesday, they started selling the January issue--the ones with the eclipse glasses. None of the messages I read indicated that it was the January issue, not the December issue that had the eclipse glasses. I do not buy the magazine every month--depending on content. Thanks for your time.
Subject: ETX90M Sent: Monday, December 4, 2000 05:49:26 From: firstname.lastname@example.org (T. Belastock) 2 questions: Question#1: What model to choose. I'm considering an ETX90M for my first (and probably only) telescope. It will be used for both terrestrial and astral applications. (about 50/50) I would appreciate your opinion regarding the choice of the "M" versus the "RA" or "EC" or "Spotting" models. Is the "M" a good choice, or is one of the other models better? Question#2: Price. The best price I've found on the "M" model is $ 399.99. I have no idea if this is a really good deal or not. Can you advise if the $ 400.- is worth it or if there's a better deal around? I appreciate your time. Thanks, TomMike here: The M and RA models are essentially the same. This is the original ETX model. Neither accept the Autostar and there is no upgrade path other than selling the old one and getting an EC. Both are excellent first telescopes. The original price was $499, then it was raised to $599, so $400 sounds OK.
Thanks very much for the reply.
Subject: Newbie ETX-125EC Owner Sent: Sunday, December 3, 2000 10:02:27 From: email@example.com (John Bedford) I found your site fascinating! Thanks! I am getting close to retirement, and we own a home in Anguilla BWI (18S63W). I have always been interested in astronomy, and with the prospect of more spare time on my hands, I plunged and purchased the 125, with the basics plus Autostar controller and carrying case. I did discover that the case does not fit in the overhead or under an airline seat, so had to entrust same to the risks of being handled by AA baggage handlers in Perto Rico. The 'scope survived with only minor damage - One of the plastic fork-mounting arms broke, I made a temporary repair, and plan on ordering a replacement arm. Which leads to my question - I had quite good results for a "first-timer", and was able to get real good views of Jupiter and Saturn, Orion Nebula, etc. However, I was plagued with telescope shake, due to the constant (and quite gentle) tradewinds which are hard to avoid in my viewing location (and they do provide comfortable viewing conditions!) I did not purchase a tripod yet, I have a very stable balcony with wide cement rail at just about the right height for alt/az alignment, and I am confident that the base is very stable. Does anyone have suggestions? I had thought about trying to devise some kind of wind shield, but I feel this would be quite cumbersome. I would also like to set up a viewing site on the flat roof (requiring a tripod of some type) to give me a 360-degree view, but up there the wind problem would be even greater. John BedfordMike here: You might want to look into the tent-style observatories. See the "TeleDome Portable Observatory" review on the Accessories - Showcase Products page for one such observatory.

Subject: Field of view Sent: Saturday, December 2, 2000 16:53:18 From: email@example.com (Paul Valent) Can you tell me what field of view is? I realize that it pertains to how much of the sky you can see through an eyepiece but the numbers I read mean nothing to me. My 4 year old wants daddy to buy a telescope, would you recommend an EXT? My only concern are some of the problems I read about the Autostar. Thank you very much! Paul "still learning" ValentMike here: Apparent field of view is the angular size of the image as seen through the eyepiece. True field of view is the angular size of the sky seen. The ETX (any model) makes a fine beginner's telescope. The smaller ones probably won't be satisfactory if the interest in astronomy grows while the -90 and -125 models can be the only telescope you'll ever want or need.

Subject: ETX125 and Meade Off-Axis Guider Sent: Saturday, December 2, 2000 05:56:32 From: email@example.com Do you know anybody thats tried (or have you tried) using the Meade off-axis guider, reticle eye piece and 35mm camera. It should be possible to use the SCT Adapter from Shutan to mount the guider and attach a camera using the standard T-ring. The only problem you will have is the scope clearance through the forks, but you should be able to get some degree of sky coverage in Polar mode. I understand that the ETX is not the best scope for long exposure through the telescope photography, but it may be possible to get some ok results with this setup. It has to beat using the camera view finder. Anyone tried it? Best Regards ChrisMike here: I've been wanting to try an off-axis guider but haven't done so yet. Anyone used one with the ETX?
Subject: ETX 90 or ETX 125EC ? Sent: Friday, December 1, 2000 10:55:40 From: firstname.lastname@example.org (Matson, RollandX E) I have really enjoyed your site and all the contributions users have added since I started researching new telescope products during the past few month's. After reading hundreds of articles on scopes of all types& trying to get a"feel" for what is right for my rekindled interest in astronomy, I have focused on the ETX line as a likely next step. My experience goes back 25 years with a 60mm refractor and its obvious limitations. The question in my mind is, if you were to step into this hobby with some experience but a 20 year gap , which model would you chose? From surveys and comments posted on the web it would seem that the ETX 90 has left a more favorable impression on its users. I suspect this is because it has been on the market longer and some of the " bugs" have been worked out. Since you now own a 125EC does the added apperature make viewing significantly better. I understand the limitations on astrophotography with these instruments, that is not my primary interest, but viewing is. Do either of these provide truly satisfying deep sky views? I would appreciate your thoughts. Sincerely Rolly MatsonMike here: The ETX-125EC I have is on loan from Meade. I only own the original ETX model. There are arguments that can be made on the side of either scope but it comes down to whether you want the increased portability of the ETX-90EC or the larger aperture of the ETX-125EC. Your choice. Your decision.
Subject: 4504 site? Sent: Friday, December 1, 2000 09:32:36 From: email@example.com (Eric Ball) Love the site, found it around 18 month ago when I really wanted an ETX but couldnt really justify the cost. Then recently got the bug again and discovered the 4504 selling here in the UK for some $430.00 or so and decided, its now or never! My 4504 arrives next week and after learning how to assemble I shall be packing it for a 3 week vacation in New Zealand. Any suggestions re set-up when I get down there? Also, love all the astrophotography it just goes to show that even comparative amateurs can get stunning results with patience and ingenuity. Do you plan to broaden the site to include more other Meade telescope information or, if not do you know of a similar site covering the Newtonians? All the very best and thanks for a really great site. Best regards, Eric Eric Ball tel +44 (0)1952 813558 cell +44 (0)7884 468272 E-mail firstname.lastname@example.orgMike here: The discussion about expanding the site to include other telescopes came up earlier in 2000. To avoid too much fragmentation I elected (without a recount...) to keep the site focused on the ETX line and related scopes (such as the DS models which include the Autostar). It remains to be seen if the LX90 8-inch is system that should be added to the site. Since it uses the Autostar, an argument could be made (but not in court, please) that the site should cover it. We'll see as the scopes get out in the field now that dealers have them.
Subject: Solar Filters Sent: Friday, December 1, 2000 08:56:13 From: email@example.com (Dave Atkinson) I'd like to echo Calvin Martini's comments about the Orion solar filter. I am very satisfied with both its quality and price. I too was taken aback by how hard it is to locate the sun when using the filter. The density of the metal film is such that the sun is the only thing you can see, and it's not as big as it looks! Attempts to point the scope by minimizing its shadow were both useless and frustrating. I solved this problem by inventing my amazing film-can finder. I drilled a small hole in the lid of a black plastic 35 mm. film canister, then snapped the lid onto a translucent white film can. With a little persuasion, the film can was pressed into the mounting ring for the ETX's otherwise useless finder scope, with the opaque pinhole end facing forward. (The finder was long ago supplanted by a Daisy red-dot sight). Both the film can and the mount ring's interior have slight tapers, so the rearward set of adjusting screws can be used to help retain and align the film can. The pinhole projects a white spot on the bottom of the film can, and when it is centered in the middle of the little central bump, the sun is usually at least partly in the field of view. A piece of tubing longer than a film canister could be used to make a more precise version of this finder. This is my 1st contribution, though I have been a long-time "lurker". My thanks to you, Mike, for maintaining a really invaluable site. Regards, Dave Atkinson
