ETX USER FEEDBACK
This page is for user comments and information of a general nature and specific items applicable to the original ETX model (now known as the ETX-90RA). Comments on accessories and feedback items appropriate to other ETX models are posted on other pages. If you have any comments, suggestions, questions or answers to questions posed here, e-mail them to me and I'll post them. Please use an appropriate Subject Line on your message. Thanks.
Mike here: On Friday, 24 November, I gave a talk on small telescope astrophotography at the Loscon 27 Science Fiction Convention in Burbank, California. It was well received. I demonstrated how any telescope, using the ETX as an example, could be used to take good photographs of the Sun, Moon, Planets, and sky with film, digital, and video cameras. I showed examples from the Astrophotography Galleries, both mine and the guest contributions. There were many "oohs" when the really good photos were shown.
Mike here: On Saturday, 18 November 2000, I attended the Oceanside Photo & Telescope "19th Annual Winter Telescope Demonstration, Star Party, and Sale". This was Meade Day (Celestron/Televue/Discovery Day was 11 November). See the "OPT Meade Day" report on the "Just for Fun" page.
Subject: Accurate angles for Polar alignments Sent: Thursday, November 30, 2000 21:17:11 From: email@example.com (Paul Loughman) For those who use Polar alignment for astronomical viewing, are using a tripod, and want to ensure that you have set the degree of tilt accurately, then I want to let you know about the Mayes Angle Finder. I wanted to be as accurate as possible when adjusting the latitude setting on my Meade Deluxe Field tripod head. I was not satisfied with the degree marks on the tripod head; too 'coarse.' I wanted a level that could accurately display the tilt angle. The Mayes Angle Finder displays tilt angles from 0 to 90 degrees in 1 degree increments. The price was under $10.00. Now I can easily set the needed tilt angle to within 1/2 of a degree. I purchased this item at Fred Myers (tool section). -- Paul O. Loughman
Subject: rumors, rumors... Sent: Thursday, November 30, 2000 20:15:22 From: firstname.lastname@example.org (richard seymour) from the LX-90 egroup: ( www.egroups.com/message/lx90/135 ) Got off the phone with Oceanside and they have 16 lx90's and were going to call back to see if they were all taken. The guy said the lx90 is quieter than the lx200, more of a higher pitched less grinding sound but still quieter than the Nexstars (slewing only) while on the phone, I asked his opinion on Meade vs. CI optics and he said they were very close but Meade had slight "image shift" problems that CI seems to have eliminated? the discussion was "how noisy are they?", but the "16 at Oceanside" caught my eye... and the "image shift" sounds like the ETX family. (i even have it in my 90!)(but only really noticable if i'm using the electronic focuser) --dick
Subject: Good ETX prices!!! Sent: Thursday, November 30, 2000 18:29:56 From: email@example.com (slider2253) First of all thank you for earlier helping me to solve a problem I had with my scope. I've noticed a ton of people looking for a place to get a good price on an ETX. Well I know of a place that discounts all models and is a meade dealer. I got my 90ec with a free electric focuser for $519 about a month ago. As I said they also carry the 60 and 70at, discounted as well. I have no affiliation with Woodland Hills Camera, just want to help more people find a good deal. Check them out at- www.telescopecity.com
Subject: do you have info? Sent: Thursday, November 30, 2000 13:39:35 From: firstname.lastname@example.org (Raymond Hansart) A while ago i started to work in a store who sells telescopes of the brand Meade. I would like to be able to inform the clients more detailed then i do now. Could you please tell me what his strongest features are, and if you have other comment please send it to Scattach@hotmail.com . Thank you very much in advance. Greetings fie.Mike here: If your customers are interested in the DS or ETX models, send them to this site. For LX200 models send them to MAPUG.com.
Subject: Subject: Solar Filters Sent: Wednesday, November 29, 2000 14:06:16 From: email@example.com (Calvin Martini) Was checking out the updates and noticed the solar filter comments from Noah(LooneyRoo). I too bought an Orion solar filter for my etx-90 a few weeks back. I have only used it once or twice, but I have nothing but good things to say about it so far! The color is great, orange/yellow, and it fits nicely on my etx(I only had to add one foam insert to the inside rim to get a nice snug fit). It appears to be a high quality glass filter and I am really glad that I decided to go with a full aperature glass filter. I live in Canada and the service was fast! I emailed Orion inquiring about the shipment and they responded promptly to my request. All in all, a great company in my opinion. I live on the East Coast, New Bruniswick, and we should see nearly 60% of the sun covered!! Well, that is if the weather co-operates and it is sunny--crossing my fingers big time on that one :). The one thing I had not realized would be so difficult is trying to find the sun without the use of any type of finderscope! It turns out to be harder than you think!! Thanks to Noah for the idea of using the eclipse glasses from the Astronomy today issue, what a great idea. Does anyone have advice/comments on using the solar glasses for making a filter for the finderscope? Since I am a newbie any help is always appreciated. Would the film need to be lose like the mylar type solar filters or would it simply work as is? Any advice would be great, who wants to fry their eyes figuring that one out! As always, great site! VernitaMike here: See the next message for a warning on the solar filter glasses.
Subject: Re: Solar Filters Sent: Wednesday, November 29, 2000 05:32:05 From: firstname.lastname@example.org (Tony Miles) This is directed to Noah and any other person out there who got the Astronomy issue with the solar glasses. They need to read page 99 of that issue where it states that those glasses are for the naked eye and not designed to be used with binoculars or a telescope. After reading that I would be very careful trying to use them as a make-shift finderscope filter. Take care, Tony Miles
Subject: Solar Filters Sent: Tuesday, November 28, 2000 17:09:59 From: LooneyRoo@aol.com I just ordered the Orion solar filter for my ETX today. I'll let you know what I think of it when I get the chance to use it. Now I'm all ready for December 25th! I also received the January issue of Astronomy today. They included two solar glasses with this months issue, so that the readers can get a glimpse of the eclipse without telescopic equipment. What occurred to me just as I opened the pages of the magazine is that the film on the glasses can make great solar filters for my finderscope! Pretty nice of Astronomy to provide finderscope filters for everyone! ~Noah
Subject: WATCH OUT!!! Sent: Tuesday, November 28, 2000 11:58:45 From: email@example.com (Scott Horne) Just a little hard-earned warning. When using bolts to mount the ETX-60AT to a surface, be ABSOLUTELY sure that the bolts do NOT extend more than three-quarters of an inch into the mounting inserts! There is no cap on the inserts, and the bolts will protrude into the base and cause damage! My '60 is on it's way back to meade because of this..... The azimuth slew is pretty much wrecked.... This probably applies to the ETX-70 as well. Don't know about the 90 or the 125. regards ===== Scott Horne http://starjourney.net 21:20:49.150N 157:54:18.374WMike here: This likely applies to all ETX models.
Subject: LX90 manual Sent: Monday, November 27, 2000 19:02:23 From: firstname.lastname@example.org (richard seymour) The LX-90 manual is available online... not at Meade (noooo...) but at http://www.egroups.com/files/lx90/LX90+Meade+Documents/lx90.pdf (969kbyte PDF file) --dickMike here: Hey, that's a pretty good manual. Lots of nice info on the Autostar.
Subject: camera for etx90ec Sent: Monday, November 27, 2000 15:30:21 From: email@example.com (chris farber) i am wondering what would be the best digital camera for taking both astro and land photographs using my meade etx90ec? if u have two or three different models that u suggest i take a look at and maybe even suggest a good program for my laptop for transferring images, enhancing them things like that. if u need to know the platform i will be running the image software on is a dell latitude 650mhz 12gb harddrive pretty much a kick-ass laptop. thank u for any and all information. please respond to Farb7276@excite.com.Mike here: Some cameras come with editing software such as Adobe PhotoDeluxe. This may be sufficient for your needs. There are also shareware applications for Macs and PCs. At the other end of the scale is Adobe Photoshop 6.0. It is an excellent but expensive package. As to a camera, if you look through the Astrophotography Galleries on my ETX site you'll see that many cameras can be used to take good photos. Some suggestions for minimum requirements: real zoom (not digital) to get the camera lens close the eyepiece, manual exposure control, manual focus control (may or may not be needed), tripod mounting hole (in case you want to put it on an adapter like the Scopetronix Digital Camera Adapter), and a self-timer (to let vibrations dampen out).
Subject: Video astronomy? Sent: Sunday, November 26, 2000 11:30:24 From: firstname.lastname@example.org (ours) I saw your trip to the OPT and I was checking out there webpage when I came across this. I was wondering if anybody you know or have you tried this out it sounds really good,please let me know thanks Jim
Subject: image - opposite??? Sent: Sunday, November 26, 2000 10:12:50 From: email@example.com (Julius Baradas) If you don't mind but I have two simple questions to you from an extreme amateur like me. First, I just recently bought an ETX-90EC. The salesperson showed me how powerful this telescope is by focusing the "EXIT" sign inside the store. I was amazed on how powerful this telescope yet able to to focus on an object that close (30-40 feet). When I got home I finally tried the ETX-90EC on a somewhat clear night in Los Angeles. When I tried to focus my telescope to focus (or align) my viewfinder I noticed all objects I focus with alphabets (street and building signs) were the OPPOSITE. I mean as if I was reading the newspaper through the mirror in the bathroom. I was wondering if you ever encountered that before or from your readers in your website??? My second question is regarding about the standard eyepiece that came with the ETX-90EC. Can you please recommend a standard set of eyepieces to someone like me since I noticed I could not see any galaxies with the standard eyepiece (SP 26mm). Thanks again!!! JuliusMike here: Maybe you missed the comment in the ETX manual (page 17 in mine, under the optional accessories: Erecting Prism) but when using the normal eyepiece position on the top of the ETX, the image is upright but reversed. So letters on terrestrial objects will appear backwards. As to optional eyepieces, check the Buyer/New User Tips page and the Accessories - Eyepieces page on my ETX site.
thanks.........i actually found it after sending you my email. thanks again.
Subject: Etx 90EC Alignment/Collimation question Sent: Sunday, November 26, 2000 03:06:04 From: firstname.lastname@example.org (Sam) I was wondering if you could answer a question for me. I am new to astronomy and this scope. I took it out last night and centered it on Jupiter. Wondering about collimation problems I read about on your site I turned the focus knob until Jupiter turned into a wide circle with black hole in the center. I noticed that the outer circle was not round it was more of an oval, slightly cut off at the bottom. I slewed the scope so that the image was slightly higher in my view and the wide circle became perfectly round. Does this mean that my scope is out of Collimation of mis-aligned in some way?. I tried the same test with another ETX 90 and found that the circle was perfectly round when centered in the eyepiece, which seems correct to me. Thanks in advance for any Information you can give me on this, and by the way; Great Site!!Mike here: If you move the focus to an extreme you may see some cutoff, probably due to the small size of the flip mirror. As long as the rings are concentric circles and not ovals, the collimation should be OK. If you want to check whether it is the flip mirror causing this, mount an eyepiece in the rear port using an appropriate visual back and adapter. This will eliminate the flip mirror from the light path.
Subject: Jupiter and Ganymede Sent: Saturday, November 25, 2000 20:18:40 From: email@example.com (Larry Smith) I had a good night viewing Jupiter tonight with both my new ETX and my 6" f/5 Newtonian. It was an interesting comparison. Jupiter was particularly interesting because the red spot was visible, and Ganymede was moving across Jupiter's disk at high latitude. For about 1/2 hour the seeing was excellent, and at 140x the ETX revealed both features. Ganymede was interesting, since at the high latitude, where the planet disk is darker, I could see both the moon and it's shadow clearly. Usually the eclipses are at lower latitudes, and the moon is difficult or impossible to see since it's about the same brightness as the planet, leaving only the moon's shadow clearly visible. The comparison with the 6" was interesting. I've read that a 6" Newtonian should reveal about as much planetary detail as a quality 3" refractor. Also, the 3.5" ETX should perform similarly to a 3.5" apochromatic refractor. It appeared that both estimates were true, indicating that both my scopes are up to par. I could just glimpse some additional detail with the 6", but fleetingly. The images through the ETX were much steadier, and therefore easier to view. It appears the the ETX makes an excellent planetary telescope.
Subject: Cracked base Sent: Thursday, November 23, 2000 09:57:10 From: HOYNACKIJJ@aol.com Your information sharing program is excellent. GREAT! I have an ETX Model M, which I carry on our motor home travels. I have been keeping it in foam lined plastic tool box. To my sorrow I discovered the tool box is too small for the major diameter of the base. I have cracked the plastic base (plastic piece through which the R. A. control knobs are attached). Is this base critical to the system which must now be replaced or is it only a cover which I can patch with duct tape? (Scotch tape looks better) I would appreciate your comments. Jerry Hoynacki Johnson City, TNMike here: The base is part of the support of the telescope and so a cracked base is going to weaken the whole system. However, depending upon the extent of the crack, it may or may not be a problem. You can try taping and see if you have problems. If you do, contact Meade for a repair.

A number of people mention Astrocap and Astrostack software. Do you have any links to where I could get these? Much obliged!

Subject: Meade Tripod Mod Sent: Wednesday, November 22, 2000 08:39:42 From: firstname.lastname@example.org (Kate and/or Tom Harnish) Do you have an e-mail address for someone at Meade that will send me the free leg mod for their tripod. Mine's starting to slip. BTW, tried the idea of putting something heavy in the lower legs (I used Instant-Rock from Home Depot) and aside from the fact that that it got hard much faster than they said it would it worked great. Makes the whole contraption much more stable. Guess I won't be lugging it to Hawaii again, though! Speaking of which, spend the night on Haleakala last month (huddled behind the USAF Space Surveillance Complex in between some Univ of Chicago shacks to get out of the wind. Frustrated to exasperation trying to get my digital camera working with the ETX. Got a couple of decent pictures of the moon, though and sure enjoyed the view of the milky way and visual observing. But attempts to image the Milky Way were wasted.... "But try, try, try again for who knows what ye shall accomplish" Tom
Subject: Meade eyepiece size Sent: Wednesday, November 22, 2000 07:15:09 From: TSCDH@aol.com I noticed a system that will attach an Olympus 3030 digital camera to the ETX-90 telescope, in your Sept. 2000 archives. I am using the Photosolve system. The problem I have encountered is with the physical size of the SP 40 mm eyepiece. The eyepiece has to slide into an Orion adapter which has an inside diameter of 1-15/32 inches. I have been told that the SP 40 mm eyepiece is 1-1/2 inches in diameter. Could you give me the actual dimensions of this eyepiece i.e.: Diameter, overall length and the length from of the body ( black portion only ). Can you also send me the physical measurements on the SP 32 mm eyepiece. Thanks... TedMike here: I don't have these Meade eyepieces. Hope someone else can supply the info.
Subject: Questions Sent: Wednesday, November 22, 2000 07:05:16 From: MREYNOLDS@expl.com (Mike Reynolds) Thanks for the information. What's a red light spotting scope? The ETX 90 spotting scope is hard to use when the scope is aimed high. I saw Jupiter and Saturn last night for the first time with the ETX 90. They were exciting to see but rather small in size. Which tripod do you recommend?Mike here: See the Accessories - Finderscopes page for info on red-dot finderscopes like the Scopetronix LightSight. See the Accessories - Tripods for info on tripods.

Subject: Putting the little scope that could through its paces Sent: Tuesday, November 21, 2000 10:25:20 From: firstname.lastname@example.org (Charles Piso) Charles from Massachusetts here again. I did several things two Fridays ago, first I met Joe Hartley from Frosty Drew Observatory in RI. They are a great group of people there, always willing to take the time to answer any questions and let you try whatever scopes are around for comparison. Then I brought out my ETX, and in between waiting to get on the 16 inch scope a small group of die-hards, and myself put it to the test, the ETX 90EC never ceases to amaze me. It was a cloudy night at first but we actually got in quite a bit viewing as it got better and better the later it got. Jupiter and Saturn were first on the list and both provided stunning views, with Saturn its brightest in the last 25 years it has been a particular favorite of mine this last year, one moon was visible and the rings never fails to impress those seeing them for the first time. Jupiter was no less spectacular showing clearly its banded pattern and with 26 mm ,and a Celestron Ultima barlow the great red spot was visible, a little washed out but there the images were sharp and clear right to the edges, I think I have to give the Ultima barlow a plug because it slightly edges out the Meade shorty in its performance characteristics. Next we turned to the Ring Nebula [M57] the best views with the ETX were obtained with A Tele Vue 32 mm plossl and Orion Ultrablock filter. The little smoke ring is joy to see under dark skies and the contrast added by the filter was so impressive that I am going to purchase one very soon. We also took in [M27] the Dumbbell Nebula, again very impressed with the filter even with my Tele Vue 32 it has never been an easy target from my yard. The great Orion Nebula [M42] took on spectacular proportions filling the eyepiece with much more detail and filamentary structure present. Trapezium's fourth star was blinking in and out of view. Next were a group of clusters [M15] the Great Pegasus Cluster is one of six globulars brighter than 7th Mag. visible in the northern hemisphere. Because of its greater distance it appears both fainter and more compact than [M13], but it is a great target for the ETX, and for me it is also seen better with averted vision showing some of its spider like structure under dark skies. Then [M35], [M36], and [M37] were targeted by both the 16 inch and the mighty little ETX. This trio of open clusters is stunning in any scope and for me the 32 mm and 26 mm are about the best possible EPs looking at this type of cluster. Later I aimed the little scope at the Double Cluster in Perseus this object is one of the finest celestial showpieces in the northern sky and are cataloged as [NGC869] and [NGC884] usually viewed best in a rich field scope the whole structure is visible with the Tele Vue 32 mm, and I think this was by far the most commented on object seen through the ETX. Given the competition though that's not surprising. The observatory's 16 inch LX200 however the little scope kept them coming back to the eyepiece all night, and disappointed no one. Joe thought he saw the faint nebulosity of the Pleiades [M45] the seven sisters for the first time using the Tele Vue EP but then thought again, due to some cloudiness, call me an idealist I think he was right the first time. Although I bought the 32 mm for use with my six inch scope I believe it to be one of those eyepieces that proves itself perfect for any type of use and would highly recommend it to other ETX owners. All in all a great night of viewing given the ever changing New England weather, horizon to horizon clouds and mist, horizon to horizon stars and planets, and on the way home a rain shower and a snow squall. I know with your user group Mike I am preaching to the choir but if you want to get the most out of any scope learn the basics (the constellations and star hopping), and know the limitations of your equipment. Visual astronomy is one of the best ways to find serenity and a sense of balance in this life. The ETX 90 is probably the best innovation in astronomy in the past twenty years. I own several scopes, but this little wonder is easily my most used, and that's what really counts Clear Skies To All Ps. Another shameless plug look up your local group there are alot out there. One of the best in my opinion is Frosty Drew Observatory www.frostydrew.org/observatory. The life list put together by Les Coleman is a great starting point and everything on it is visible to the ETX Added later: I was lucky tonight had crystal clear skies for the leonids the moon was not very cooperative, but it and the four visible planets made for some interesting distractions. Early in the evening I pushed the ETX to 181x on Venus low on horizon but still good views would say it was gibbous looking very bright sharp images with 13.8mm superwide and ultima barlow. later did the same with Mars vivid color, but the horizon and the moon working against me tonight. Jupiter and Saturn were their usual showpieces they really strutted their stuff with the Meade 13.8mm. I was counting about 27-30 very bright fireballs per hour, when I got tied and put the ETX on the Moon the new EP again showed that Meade has a winner with the 13.8 superwide.

This is where the ETX actually out-shines the 16"! Even with our widest FOV eyepiece (the 40mm University Optics MK-70 Konig) we only get about 2/3rds of a degree for a field. This means we can't get more than one of the two clusters in the field at any one time! In the ETX, it's two handfuls of diamonds on velvet! > Added later: I was lucky tonight had crystal clear skies for the leonids > the moon was not very cooperative, but it and the four visible planets made > for some interesting distractions. We were very lucky to have a superb display at FDO despite the moon. From 1:30 to almost 3, we were seeing hundreds per hour. As 3:00 AM approached, Les commented that it was as fine a display as he'd ever seen. I commented that all we lacked was a big fireball, for which the Leonids are known. Almost at 3:00 on the dot, an enormous fireball, mag -5 or -6, streaked across the sky from just past the zenith heading due west. This was followed by a few dozen smaller meteors within the next 10 seconds. Like the grand finale to a fireworks show, this signaled the end of the evening, as things trailed off significantly after that. Thanks for the kind words about FDO. We're open every clear Friday night all year around for our public sessions. -- ====================================================================== Joe Hartley - Technical Director - Frosty Drew Observatory 12 Emma G Lane, Narragansett, RI 02882 - 401.782.9042 email@example.com - http://www.frostydrew.org
Subject: Meade ETX 60 Sent: Tuesday, November 21, 2000 07:50:59 From: firstname.lastname@example.org (xzhang) Thank you very much to put on such a infomative site. I have been always like to purchase a telescope. From the comments on your site, ETX60 or ETX70 maybe a good start. But I do have one concern. Some people said, through small telescope, most planet and deep sky object are black and white because they are too dim. They will not look as colorful picuture on the telescope box. Is that true? Will photos looks better than what I will see using my eyes? Thanks. SeanMike here: The eye is a pretty lousy astronomical instrument compared to CCDs and film. In low light situations, like when looking at nebulae and galaxies, colors are lost due to the construction of the eye. So yes, long duration photos will look more colorful than what you see with the eye.
Subject: Christamas confusion Sent: Monday, November 20, 2000 09:53:22 From: email@example.com (Bingo Wall) Help! I am hoping you can give me some advice because I am shopping for a telescope and know NOTHING about such! Any pointers you could provide would be appreciated. I am looking for a scope in the $350 to $500 range that can be used by a college student (hobbyist only - not related to her studies) both in Massachusetts and in Africa while she is doing her semester abroad. It must be super portable (no long tube) and hopefully come with (or have available) a battery charging system for European current. However, I would hope she could enjoy the darn thing for many years to come in the States just viewing standard planets, stars, etc. I have been looking at the Meade ETX-90 and the Astroscan 2001 Wide Field Telescope w/ Image erector on the Internet. Any thoughts? Advice? Am I nuts? Clothes would so much easier to buy but much less fun. Thank you. Jenny WallMike here: Certainly the ETX-90EC will make a nice portable, long-lived telescope. It runs on AA batteries (rechargeable or not). Check the Buyer/New User Tips for some info on accessories. Recent Feedback pages have more thoughts on what to consider when purchasing a telescope.
Subject: Foam For All Cases Sent: Monday, November 20, 2000 07:44:22 From: David.Ferber@allgon.com I have been using your website since last year to assist in evaluating telescopes. Based upon your membership's feedback, I purchased a ETX-90EC for Christmas last year and have not been disappointed. I have since been looking at different cases to transport it, the Autostar, the original control, multiple lenses and other accessories. There are some terrific case suggestions on your website. However, none of them mentioned where I could get foam padding to put inside. Having spent a tidy sum on the ETX equipment, I wanted to ensure that my investment would be safe. I could have "borrowed" foam from work, but the would not have the done the nice job that I wanted. I have found a retail distributor that carries charcoal R65 cubed foam padding for these great case suggestions. Right now, they only sell two different sheet sizes: * 14.5"x19.25"x2" * 14"x18.875"x2" Each sheet costs $4.50. The company is: Dallas Foam Inc. 2171 East Southlake Blvd. Southlake, Texas 76092 USA (817) 481-5551 This will give your membership and readers a venue to get this foam to protect their investments. If they begin to see an interest in this product, they will consider expanding the sizes, colors, etc... that they carry.

I didn't check what currency was being used but the list price in US Dollars is $595, which is the same as their "deal price".
I've never understood that, either, Mike...their sale price is $595, then deduct $100 if you take the order over $600, then another 20% off the total if you go through MSN Passport...FWIW.

Subject: hy-alpha work with ETX Sent: Saturday, November 18, 2000 07:57:42 From: email@example.com (Richard Bailey) The red pre-filter I use on the LX50, and previously on a LX200, is the one supplied by Thousand Oaks when I bought their h-alpha prominence filter. Iy has always worked OK with my other Meade SCP's. I am asking Thousand Oaks whether they make a pre-filter for the front of an ETX, so that their h-alpha prominence filter can be used on an ETX as on other Meade LX scopes I have used successfully.

Subject: etx-90ec Sent: Saturday, November 18, 2000 05:56:52 From: Rmtc09@aol.com Please excuse my most simple questions, but I am new the this area, and want to make good decisions when it comes to purchasing my etx telescope. I am looking at either the etx 70-at or the etx-90ec. Is there a dramatic difference between them that would justify the extra cost of the 90? I don't mind paying the extra cost, but just want some indication that it is the right thing to shoot for. Second, I am not clear about usability. Is the field tripod a necessity or a near necessity? When looking at the 70-at, the indication is that all that is needed is a flat surface, and this would seem to imply that a table outside would work. Yet when I read about the 90ec, indications seem to imply the field tripod ($200.00) is needed. What accessories are reasonable to make the scopes usable and practical. It makes no sense to buy the telescope and not have the NECESSARY accessories to make it usable. Any advise or recommendations will be appreciated. firstname.lastname@example.orgMike here: You will see more through the larger telescope, as to be expected. The -90 has a larger aperture and a longer focal length than the -70. This means you'll see fainter objects and you'll be able to use higher magnifications on the -90. Any stable flat surface will work with either model provided you have the Autostar (which is an additional purchase item with the ETX-90EC). With the Autostar, the telescope will track the sky when mounted in what is called "Altitude/Azimuth mode" or Alt/Az for short. If you don't have an Autostar and want the telescope to automatically compensate for the earth's rotation, then you have to mount the ETX-90EC in "equatorially", also called "polar mode", where its vertical axis is tilted to match your latitude. That requires either the optional table top legs for the ETX-90EC or a sturdy tripod. As to accessories, see the Buyer/New User Comments page.
Thank you for your help. I appreciate your time.
Subject: Re: It ain't natural!!! Sent: Friday, November 17, 2000 22:01:18 From: email@example.com (Larry Smith) I have the ETX Model M (90 mm). I have confirmed that my clock drive isn't working. The motor is, but the drive gear isn't. I assume the gear box has something stripped. Out of the box, I didn't notice till I read the hints on your web page, but I think the screw attaching the base was too tight, and it probably stripped the gears. No problem, I have a small equatorial mount to put the ETX on for now, with a clock drive. Do you think when I send in the warrantee I can simply ask for a new drive train? Or, failing that, only send in the mount, so I can use the scope? Anyway, the scope is fantastic, and soon as the clock is working, I have no heartburn with the mount either, though for home use I may still just use the equatorial.Mike here: I would suggest checking with the dealer where you purchased it. Maybe they will exchange it. Otherwise, contact Meade; they will provide warranty return information.

Subject: "Help with a decision" Sent: Friday, November 17, 2000 08:57:50 From: email@example.com (mike dunlap) Not sure if I am knocking on the correct door with my question but here goes! I have been looking at the Meade ETX-90, ETX-125 and the Celestron NexStar5 for our "first" telescope and was hoping you could point me in the right direction. We live out in the country in WI and enjoy both astronomical and land viewing. I am not the "diehard" viewer that many of you are but I don't mind investing more up front to insure a quality item for a lifetime of enjoyment. It will get used everyday in both land and sky views! We have 3 young children so I know they will enjoy the views as well....... Any other suggestions or comments are very much welcome!!! Thanks for your time and efforts in this matter. Happy Holidays! Mike Dunlap PS I enjoyed reading your comparison between the ETX-125 and the NexStar 5 I am still having a hard time deciding which way to go.....or if the ETX-90 would do just fine for us........or something else..........Thanks again!!Mike here: For daytime use the ETX-90 would be the more obvious choice. The larger size of the ETX-125EC and NexStar5 would be wasted on day viewing. However, for nighttime viewing, the larger aperture of the 5" telescopes comes into consideration. However, you will sacrifice some portability with the larger scopes.
Subject: Re: Meade ETX-90M Sent: Friday, November 17, 2000 07:04:21 From: SKBROTHERS@aol.com Thanks for your prompt response! I also received a response back from someone at Shutan. I assume you inquired about the unique model number (ETX-90-M) from Sam's Club with him. One final question for you then I will make my decision on this scope. I have seen many many message board posts that really tear down the quality of the ETX-90-EC drive gears. Many say they are inferior, noisy, break often, and in general don't track objects accurately. Do you have any insight on this topic? I do feel the autostar would greatly enhance my interest in the night sky as it's been 10 years since I took astronomy in college. If the mechanical integrity of the ETX-90-EC is questionable I am not real interested in throwing the extra $200 at it. Additionally, I just stopped into Natural Wonders and they are selling the Celestron models now. Including a new Nexstar 4 for $699. The focus knobs look like they're easier to work with, there are more objects in it's computer tracking database and the computer controller is included. Additionally, I've been told the tracking motors are quieter than the Meade's. I think it has roughly the same aperture as the ETX-90 series. I can't find any good reviews of this product. What is your knowledge of Celestron and the Nexstar 4 specifically. I understand Celestron has been bought by Tasco; which doesn't fill me with confidence. Hate to keep leaning on you and I promise this is my last extended question. I found your last reply very concise and helpful. As a result, if my decision is between marginal mechanical integrity or manual star hopping I will definitely choose the latter. Again, as always, thank you for your assistance. firstname.lastname@example.orgMike here: Bob Shutan (owner of Shutan Camera and Video) frequents our ETX site and contributes a lot of good information. The ETX optics are the better component while the mechanical systems are less than optimal. But a better drive mechanism would mean more cost and that is not the target market for the ETX line. It does the job. Yes, it would be nice if it were better with NO backlash, NO slop, and NO errors. But even the NexStars can't make this claim from my brief experience and from what I have seen on the Net. So, there will always be tradeoffs in making your decision.
Subject: It ain't natural!!! Sent: Thursday, November 16, 2000 20:58:30 From: email@example.com (larry smith) Nice web page -- excellent in fact. Since I was a tad (a few decades ago) I've read about the incredible things one can see with a 3.5" Questar. More than once I decided I'd save up and get one, only to come to my senses and realize there's no such way such a small scope could do that. So I've owned numerous other scopes, mostly Newtonians, 4.25" to 10", now back to an f/5 6". Bought the Meade 392 refractor (90mm) for planetary work, was very disappointed in it, then learned it was a Chinese import. For the last few years, the ETX radicals began putting forth that same unbelievable Questar-ian rhetoric about the new ETX. I briefly thought about buying one, remembered the useless Meade refractor I had, and thought better of it. Then, the other day I stumbled across the ETX in a Sam's Club for a price hard to ignore. On impulse, I bought it, figured I could get most of my money out of it if need be. I've used it the last few nights to view Jupiter and Saturn, and a few stellar objects. It's hard to admit it, but I'm now a believer. I should have bought that Questar when I was a kid, I'd have enjoyed the heck out of it all thoses years. The only complaint I have so far about the ETX is that the clock drive on mine runs too slow. Maybe with use, bearings will break in and it'll work better. The rest of the mount is fine by me, if it holds up well. It's enormously portable, non-shakey, pretty easy to use. But the images. I can hardly believe the definition, after all those moderate to poor images I've seen on those Newtonians and the import refractor. The detail on Jupiter knocks my socks off. Cassini's division pops out (with good seeing) as well as those fanatics said. I'm sold. For stellar, I still love my 6". I can move the entire apparatus around without disassembly, and get great wide field star images. But now, finally, I have a supurb lunar/planetar scope that's even more portable.

Subject: H-alpha solar observations Sent: Thursday, November 16, 2000 12:53:47 From: email@example.com (Richard Bailey) I have just checked out your web page....all good stuff !! I have been thinking of buying an ETX90 for solar observartions, which I do at present with a Meade 7" LX50 Maksutov-Cassegrain. I use a Thousand Oaks H-alpha Prominence Filter, plus a red prefilter over the Meade, with a binocular viewer plus eyepieces. Do any of your ETX users know whether this H-alpha/binocular viewer system will work with an ETX90 ? The smaller 'scope would be more portable than the Meade LX50 !!! Richard Bailey Barham,Canterbury, UKMike here: You need to have the solar filter at the objective end of the ETX to avoid damage to the telescope. But beyond that, an H-alpha filter should work fine on the ETX. And binocular viewers do work in the ETX.
Thanks for the prompt reply about using an ETX for h-alpha work on the sun with my h-alpha system. The prefilter I use on the front of my Meade LX50 has a red glass of about 72mm.diameter to let light through for h-alpha filter viewing, with the binocular viewer in the end of the h-alpha filter. As a thought, would this red glass 72mm.diam, prefilter not be effectively reduced in area by the ETX secondary mirror ? What is the diam. of the ETX secondary for comparison ?Mike here: A red filter on the front of the ETX will not be enough to avoid damaging the telescope. You will need a solar filter of some sort (full aperture ones do exist; see the Accessories - Filters page). Whether they will let enough light through to allow the use of the H-alpha filter, I don't know.

Subject: User feedback ? Sent: Thursday, November 16, 2000 06:25:54 From: email@example.com (Scott Powell) I saw a post in the user feedback section from SKBROTHERS@aol.com who was trying to decide between an ETX90-M (no autostar) vs a -60 or -70 with Autostar. My two cents worth - if he can't afford a -90 WITH an Autostar, I would recommend getting the -90 without and getting a good book such as "Turn Left at Orion". I originally had a -90RA, and last year upgraded to the ETX-125. I still feel that using the Autostar is a bit of cheating - yes it makes it much easier to find things, but doing it the way "Turn Left at Orion" shows is a lot more fun! (in my opinion, of course) Thanks, Scott
Subject: Meade ETX-90M Sent: Tuesday, November 14, 2000 20:17:02 From: SKBROTHERS@aol.com I am considering the ETX-90-EC as a first scope. However I was walking thru Sam's Club and found a skid of about 15 ETX-90M telescopes. Any idea what this unit is? It appears to be the same thing as the ETX-90-RA. There is no hand controller or any provision for one. There are two switches on it's base: one for North or South Hemisphere and one to engage the tracking motor (One speed I think). The thing is that the price on this scope is only $399.00. Initially I was considering the ETX-60-EC for it's price and autostar capabilities. I have since decided that I might be better served with the optics of the ETX-90 series. What are your thoughts on the autostar vs. larger optics. The $399 is appealling but will I regret not getting the duel drive motor with autostar? The ETX-90M has the little tripod legs and I don't know if it can be mounted on a tripod. Could this be a refurbished unit? Any thoughts would be appreciated. I intend to buy a scope for Christmas. Thanks!!!!!! firstname.lastname@example.orgMike here: The ETX-90M apparently is the same as the original ETX, now known as the ETX-90RA. $399 is a good price for that model. It is certainly a capable telescope as evidenced by its original success. Until the ETX-90EC was released, this model was the only ETX model and so most of my site up until January 1999 was about the original model. The original ETX was what motivated me to even start this site! It can be mounted on a tripod (see the Accessories - Tripods page). Certainly the extra aperture and focal length of the -90 model make it a more capable telescope than the smaller -60 and -70 models. Will you miss the GOTO capabilities? That depends upon your familiarity with the night sky or your willingness to learn it. It is worthwhile to remember that mankind observed the sky for several centuries without a computer. But as some have noted, if you live in light polluted areas having the Autostar will possibly let you locate objects that would otherwise escape your notice. Will you get more out of observing with an Autostar? Sure, because it does a lot of the work for you. Is that worth the extra money? Only you can say. Always trade-offs! Good luck with the decision.

But to check a used scope try to actually star test it. Pick a bright star like Sirius. Run the focus from one side of exact focus to the other out-of-focus side; in the out-of-focus positions you will see some rings. Symmetrical rings show that the optics are in collimation. Check the physical condition (motor drives work, optics clean and not scratched, and general cleanliness), plastics not cracked, etc. Don't forget to check the accessories. Check the play in the axis with the locks engaged; should not be excessive (more than just a few degrees). Check the battery compartment for corrosion. Check the base mounting holes for stripped threads. Run the drives normally and verify there is no excessive jumping or other oddities. Check all the buttons on the standard controller and Autostar. They should all work. Hope this helps.

Subject: Meade day Sent: Monday, November 13, 2000 05:11:08 From: email@example.com (Dean Schwartzenberg) I have a LX90 on order. They are supposed to ship this week to us. Will you get a chance to look at it? Possibly compare drive train and autostar to etx and lx200. I have never used an LX200 but know that they are near 100% perfect in goto. According to the meade adv. the lx90 should be nearly the same. Also the mount is a concern after dealing with the 125. The LX200 tripod I am sure is fine, but the actual forks and telescope base? Since this scope is a 'hybrid' of the etx & lx200, do you think you may have a section on this scope? With the autostar being the same, it sounds like it will be a very similar scope in operation. Hopefully all earlier autostar bugs have been fixed. Thanks, Dean.Mike here: I hope to check out the new LX90. As to whether we'll have a section on here, remains to be seen. It does use a version of the Autostar so from that standpoint it would make sense. On the other hand, it is a pretty large telescope, going beyond the ETX models up to 5-inch. Decisions, decisions, decisions.
Subject: RE: RE: #126 Barlow Sent: Sunday, November 12, 2000 21:21:30 From: firstname.lastname@example.org (James A. Cleland) I can focus on either side of "focused", so it's not a range thing. I can see at what point the object becomes as clear as it is going to, It's just not absolutely clear. Even the moon, you can tell there is a little fuzziness to it. I'm going to get a nice rag out and clean it tomorrow to see if this helps. If not, I may just try another lense. Perhaps this one is defective. Also, is it normal for things to be completely out of focus when you insert the barlow after they were in perfect focus with just an eyepiece? I'm speaking of a 9.7 Plossl. Thanks again! JamesMike here: There are eyepieces and Barlows that are "parfocal", meaning they focus at the same setting. But the 26mm is not parfocal with anything else. However, you can attempt to make things parfocal by some experimentation and not inserting eyepieces all the way in.
Subject: #126 Barlow Sent: Sunday, November 12, 2000 17:35:33 From: email@example.com (James A. Cleland) I love the site. Bet you get that alot :) I thought you might be able to answer a quick one for me. I have been having a little trouble with my Barlow lense and I don' t know if it's defective or if this is normal, but I have a heck of a time getting a good focus with it. Actually, I never really get a good focus. I have been using this lense for some time now and I don't think the halo's that I'm seeing are problems induced by the atmosphere. How do you feel about the image quality you notice with the barlow and various eyepieces? BTW, I'm using it with the 26mm, 18mm, 9.7, and 6.7UWA. Thanks for any input! James A. ClelandMike here: You didn't indicate which telescope you use the Barlow with but on my ETX-90 and -125, it works fine with the 26mm eyepiece. On the -90, things do get a little fuzzy on faint objects with the 9.7mm plus 2X Barlow Lens. But other than that, I've not seen any halos. Could yours just need cleaning? I assume you don't see any halos when you don't use the Barlow.
Thanks for the response! It's a 90. I have checked the optics pretty well and they seem to be spotless. I don't clean my optics often so as to preserve the coating, but I do occasionally wipe them gently. I could check it out again. I noticed there is another 2x Barlow (#122) that is much longer than the #126. What's the difference?Mike here: The short #126 Barlow is recommended for the ETX. If you can't reach a good focus you may have to adjust the position of the focus knob. If you turn the focus knob and it hits the back of the ETX before reaching a good focus, just loosen the setscrew on the side of the knob, slide the knob just slightly outward, and retighten the setscrew. Be careful to not let the shaft fall inside of the ETX tube (point it upwards before loosening the setscrew).

Subject: weather effects on 125 and double stars (not related) Sent: Sunday, November 12, 2000 12:40:07 From: email@example.com (Emory Braswell) Mike, I am bothering you and your extremely useful site again--I need some technical kinds of info. First; does anyone know how much weather the 125 will take? I live in Connecticut which can be quite damp, and occasionally cold or hot. If the scope was left out on its mount with a heavy plastic bag over it--is that enough? What about moisture condensation and possible freezing--How about leaving it in an unheated garage? Now the second more complicated issue. I am getting interested in doubles. There is a standard way of representing them, as if the brighest one straddled the zenith. Then recording the angle from N for the fainter star and of course the distance between them. Well one doesn't wait to record this only when the star gets to the zenith. Therefore there must be a simple trignometric transformation between the angle measured with relation to a vertical (or some other reference) and the LST of where you are and the RA of the star. I understand that this was (once?) done with a "filar micrometer". Where can I learn more about this and doubles in general? Thank you for your time and anyone else who will supply me with some answers. Regards to all, Emory BraswellMike here: Most consumer telescopes are not really meant to be permanently left outside. And freezing it would not be good for the plastics, glue, and optics. Moisture can cause problems as well. Dew is not a long term problem (except for cleaning) but rain would be. As to double stars, I did some research for you by starting with the Sky & Telescope web site and checked their Resources area. From there I ended up at the ad.usno.navy.mil/dsl/ Double Star Library site. Isn't the web amazing!

Subject: ETX-90EC is AWESOME! Sent: Saturday, November 11, 2000 19:48:05 From: firstname.lastname@example.org (Rick Towns) Great site! I traded in my Celstron C8 for an ETX-90EC this week (you read that correctly - I traded an 8 inch SCT for a 3.5 inch MAK). I finally got some clear skies tonight (I live just north of Toronto, Canada) and took my ETX for a run. All I can say is "WOW"! This little scope easily out performs my C8 for crisp, clear images and amazing colour contrast. I noticed that the central obstruction on the ETX is really, REALLY small as a percentage of the entire corrector plate. I assume this plays a role in the superb and sharp images. I owned the C8 for over 4 years, and although it was a decent instrument, let's face it - it's *THE* entry level 8 inch SCT. The optics were decent, but this ETX just plain blows it away. With poor seeing, I was still able to observe excellent detail on Jupiter's surface (5 bands were viewed) at over 200x. What would normally turn into an amorphous fuzzy ball in my C8 was crisp and clear with a sharp, defined edge. Saturn gave the same startlingly excellent view as well. I have the AutoStar computer and a full size field tripod, and all I wanted to say to ANYONE considering the ETX-90EC - DO IT! You'll never regret it (I picked this scope over the similarly priced but completely plain jane Tele Vue Ranger). Thank you.

Subject: Lens cleaning Fluid Sent: Thursday, November 9, 2000 08:48:26 From: email@example.com (Calvin Martini) Have a quick question for you or any of your guests. I just bought a lens cleaning kit with cleaning fluid from a small camera shop in a mall. I asked the clerk if the cleaning fluid would be suitable for telescope oculars, since camera lenses are coated too etc., they said that it was suitable for any type of lens. It looks identical to a kit sold thru the dealer that I bought my ETX-90 EC from this past summer, but at nearly 2/3 less. Does anyone agree that it is suitable for all lenses? I would not want to find out after the fact that I was misinformed! I am pretty much a newbie and I dont want to make any expensive mistakes. I already know that I should do as little cleaning on my oculars as possible. I just want to make sure the fluid is safe if I ever need to use some. What do you think? I also want to say again how much I love your site. It is so informative and helpful! I used the reviews and comments from the filters section to do some of my research before buying my Solar filter and color filters....it was very helpful. I bought a full aperature glass filter from Orion. They were prompt in filling out my order and it should arrive on my door step any day, I can't wait!!! You do such a great job at keeping this site up and running. Keep up the good work! Clear Skies, VernitaMike here: I have successfully used various lens cleaning solutions (extremely SMALL amounts) on eyepieces and the outside of the correcting lens on the ETX. I have not tried it on a mirror surface. However, I _strongly_ recommend reading the telescope instruction manual on maintenance. Here's a link to the ETX-90EC manual section on cleaning:
Subject: Aperture Rant Sent: Tuesday, November 7, 2000 06:32:52 From: Mnev326@aol.com This is response to Brian Straight's rant about aperture on the Editorial page. First of all I don't think his evaluations were valid. If you're going to compare scopes you need to operate them at the same magnification. He used just a 26 mm. With this eyepiece the 5 inch was at 73x, the 6 inch at 35x, the 8 inch at 77x, and the 16 inch at 154x. I also think he's blowing collimating out of proportion. I have a 10 inch DOB that I collimate every time I use it. It normally takes under a minute. Also, I like to have the ability to collimate to optimize my scope. If your ETX gets out of collimation it needs to be sent back to Meade. He also states that what he saw visually wasn't worth the price difference between the ETX and the LX200. I think people that buy a 16 inch LX200 are buying them to do advanced astrophotography. A fairer comparison would be the 16inch Meade Starfinder DOB which retails for about $1200.00. About what you would pay for a ETX 125 with the autostar and tripod. Now which gives more bang for the buck. I've used scopes from 2 inches up to 25 inches and believe me if the seeing is good the larger apertures always give better views. But, don't take my word for it join your local club and go to their starparties and look through as many scopes as you can and make your own decision about aperture. Mark
Subject: ETX Model M Sent: Monday, November 6, 2000 11:13:47 From: ELIZABETHA1@prodigy.net (ELIZABETH E ADAMS) no nothing about scopes and want to find one for wife for xmas. what do you think of the ETX model M @ $400 at SAMS? I know it is not on the upper price end but would it do a nice job at that price? any help would be appreciated since you know about the ETX series.Mike here: Supposedly, the ETX Model M is the original model, also known as the ETX-90RA. The current model is the ETX-90EC, which supports the Autostar. $400 for a new ETX-90RA is a good price, assuming it comes with all the original equipment: including the table top legs, 26mm 1.25" eyepiece, and 8x21 finderscope.

Subject: Re: place to buy? Sent: Saturday, November 4, 2000 05:15:25 From: email@example.com (Michael R.) I gave scopecity an order based on free electronic focuser. The salesman just wanted to take the order and get off of the phone. I hope that focuser is worth it because I saw a nice ETX90 discount at Shutan that caught my eye. I'm leary about buying a ETX90 by mail order out of concern of damage or whether it will be a return or a second. There was a return at Natural Wonder in Tulsa for $505 but I took a pass on that. I really wish your web page had a faq list for newbies of ETX90 accessories ranked in order of REAL importance. Also a faq on what to do to check out the scope when you first open the box. This may sound really dumb but to me it's not. Thanks again for your web page. Mike Reynolds, CPA, MBAMike here: Each user's needs vary as to what accessories are more important. Some want a new finderscope right away while others want more eyepieces and/or a Barlow Lens. Filters of various types can be handy for some users and less useful to others. Of course, some would rank a tripod high on the list where for others it would be low. And then you come to accessories for taking photos. The list can go on and on. Review the Buyer/New User Tips pages for some suggestions. Regarding the FAQ for what to check out when receiving a new (or especially used) telescope, that's a good idea. Maybe someone already has something written up that they could submit.
Subject: Meade sale items Sent: Friday, November 3, 2000 16:26:12 From: firstname.lastname@example.org (THOMAS) Some of the Meade products are on sale at Natural Wonders. Web site: www.naturalwonders.com We purchased a ETX-90EC for $505.00 on sale.Mike here: As I recall, NW is dropping Meade.
Subject: place to buy? Sent: Friday, November 3, 2000 04:40:58 From: email@example.com (Michael R.) I've been checking places to buy an etx-90, both local or mail order. Scope City is tossing in a free electronic focuser. Do you know if Scope City is reliable or should I stay local and pay full price? BTW: Thanks for your site. I'll be a supporter as soon as I get my scope. Mike Reynolds Tulsa, OKMike here: There used to be a Scope City near me but they closed that store many years ago. I've don't recall ever seeing any complaints about the Scope City chain.
Thanks. I hate how Meade is trying to fix retail scope pricing.
Subject: cooling time Sent: Thursday, November 2, 2000 23:29:59 From: firstname.lastname@example.org (zen420) I purchased an ETX 90EC in May 2000. I love my telescope. I have sold them in a retail store since 1997. I didn't know anything about telescopes before I started working there. We recently started carrying Celestron instead of Meade. One thing that is mentioned as a benefit of the Schmidt-Cassegrain over the Maksutov-Cassegrain is that the primary mirror has a slower "cooling time". What does this mean and how does it affect my telescope? Thanx! Also, I really enjoy touring around your site! It's very informative and interesting. JenniferMike here: "Cooling time" is actually the "thermal equalization time" for the optics, or the time it takes for the components in the telescope, including the air in the tube to reach the same temperature as the outside air. For some telescopes, with only small holes for the air to move through, this can take a couple of hours. For other telescopes it can take 20-30 minutes. While some would dispute this, I think most small telescope users will never notice much difference whether they wait 30 minutes or 2 hours or just start observing when the bring the telescope outside. Of course, if you move from a 78 degree temperature to a 20 degree temperature, there is a more noticeable affect than if you move from 78 to 70 degrees. What with all the heat sources around most homes, if you take your telescope to the backyard, this is enough disturbance going on that deciding what is due to the telescope and what is due to other heat sources is going to be difficult for most users to determine.
Subject: ETX-90 Sent: Thursday, November 2, 2000 13:19:14 From: BGJAKU@aol.com I'm new to astronomy and will be purchasing either a 90 or 125 very soon. I have one question I have not been able to get a real clear answer on. I thought maybe you could help. When people speak of "tracking" with the out of the box controller, they mean tracking by pushing the remote buttons in place of knobs, right? Does the autostar controller allow for tracking stars in the sky without touching any buttons? And do you recommend the 125 as a beginners scope? I spoke with a local dealer and he tried to talk me into the 90 because it is more widely used. Sounds strange to me. Thanks in advance Mike, Bryan KubschMike here: Tracking usually means that the scope moves to compensate for the Earth's rotation to keep objects in view. And yes, the ETX-90 models (and all ETX models for that matter) will track if the telescope is mounting equatorially (also called Polar mode). If you mount the telescope in Alt/Az mode you will need an Autostar to automatically track. In any case, the ETX standard handcontroller and the Autostar use buttons to move the telescope to locate objects. Or you can move the telescope manually by unlocking the Right Ascension and Declination locks and move the telescope tube. As to which scope makes a better beginner's telescope will depend upon your expectations (a topic which is covered a lot on my ETX site) and how you plan to use the ETX. Larger is not always better if it stays in the closet.
Subject: re: camcorder on an ETX90 Sent: Wednesday, November 1, 2000 19:54:05 From: email@example.com (richard seymour) To: firstname.lastname@example.org Thomas, I saw your note on Mike's site, and another factor to consider is that the ETX90 cannot handle much off-center weight. Its clutches and drives are plastic, and too much weight hanging off-balance will slip the clutches and can damage some of the internal pieces. You -can- hang a counterweight on the barrel, but if the camcorder is at all bulky, the effective weight will be changing as the telescope slews up and down. So the counterweight may have to be adjusted for each target. As mike says, even a 1-lux camera cannot handle dim (and almost everything is dim, except for the moon and major planets) targets. "real" astronmy CCD cameras work by either taking long (5, 10-minute) exposures, or by frame-grabbing many individual images and adding them together (this has other advantages, too). Simple video-taping of the dim targets will probably be disappointing, but using the camera to supply frames to your PC/MAc for post-processing can work very well. Try chasing some of Mike's links involving CCD and QuickCams to see what the ETX can be convinced to deliver. have fun --dick
Subject: search... yes, i use it Sent: Sunday, October 22, 2000 22:17:52 From: email@example.com (richard seymour) Of course, just a zipped whole-year's-digest would also serve... i could download -that- and use a word-processor on it. Compared to multiple downloads of the 75KB keyset it'd almost be faster on busy weekends (there was a day i download many, many months of archives for multiple searches) --dick
Subject: Search Feature Sent: Thursday, October 19, 2000 13:56:55 From: Kurt.Sowers@dtn.com I saw your question about use of the Search feature and wanted to share my experiences with you, which I assume are pretty typical. I found your site in May of this year; I was searching the net for information on telescopes because I wanted to purchase my first scope. Although I found a lot of useful information on other sites, yours is hands-down the most useful site I've found yet. Initially I spent a great deal of time reading the posts and combing through the archives gathering information about the ETX. Primarily because of the information on your site, in July I took the plunge and bought an ETX-90EC and have been very happy with it. I continue to visit your site a couple times a week. I sometimes have a problem or question and remember reading something about it on your site, but don't remember all the details. I have used the Search feature to find the information I'm looking for with great success. The information on your site has saved me a great deal of time trying to figure things out on my own. I know it seems like people aren't using the Search feature (judging from the questions you receive), but I think there are may others like me who do use the Search feature, and so you don't hear from us very often (the silent majority theory). I find this feature very useful. Personally, I'd rather invest a little time searching the archives for information and receive an "instant" answer, rather than to submit a question and wait for a reply. Although you are very timely in responding to questions, usually you direct the inquirer to use the Search feature anyway (As you should!), because the information is already out there. I suppose they think it will be easier to just ask the question rather than look for themselves. They could save you a great deal of time if they'd just spend a little time looking. Your site has been, and continues to be, an invaluable resource for me and other ETX users. If I can be so presumptuous as to speak for all of us, I'd like to sincerely thank you for the work you put into maintaining this site, and for all the help you have given us. I have no doubt that there are thousands of ETX users who would be unhappy or unsatisfied Meade customers if not for the information you have gathered here. Thanks again, Kurt Sowers

I've used the search feature several times (looking for parfocal measurements and fixes for that wonderful 26mm plossl, tripod info and product fixes. Though not necessary it is a uesful feature. Hope its not too much extra work for you. Thanks so much for keeping up such an excellent source of knowlege. The information sharing has been invaluable.
Subject: SEARCH Feature Sent: Monday, October 16, 2000 14:16:06 From: RBSAUER@aol.com Thanks for the wonderful site. A many others have said, my decision to purchase an ETX-90EC was highly influenced by your website. As for the Search feature, I have used it many times successfully. I will say that I have been frustrated at times while utilizing it. However, I realized that the information for which I was looking was not on your site but on another. I guess that is the nature of the beast when the site has so much info...I assumed I must have seen it on the Mighty ETX Site. For newcomers, like me, I think it is invaluable. After looking through many of the Archives it is virtually impossible to remember, days later, where you read that factoid of current interest. If it is not too time consuming to keep up to date, my vote is to keep it. Ron Sauer
