Subject: 125EC Sent: Wednesday, October 31, 2001 15:11:07 From: email@example.com (Paolo M) I was wondering if you could possibly shed some light on a problem I have with a recently purchased 125. When I put the tube level the dial on the side indicates about 23 and when it is set to 0 it is pointing to the ground.... curious?! The other problem I have is that the marking counter around the base is lose (it is a kind of tape) and can fall off the base. I havent had either of these problems with my 70! Thanks in advance for your help. Paolo MelettiMike here: See the FAQ for the DEC (Altitude) scale problem. The tape is just that; you can reglue the ends that are connected to make it tighter. DO NOT glue to the base; as indicated in the FAQ it should be free to move.
Subject: ETX70A Sent: Wednesday, October 31, 2001 12:30:45 From: firstname.lastname@example.org (Graham) Have read your review of the above and as a relative beginner to the hobby, have used binos to do some astronomy but am now looking for something a bit more serious. I am unsure if it would be better to go for something like the Meade or a bigger scope such as an 8inch Newtonian. Any thoughts or advice on this? Regards and good seeing GrahamMike here: You need to decide how you will use a telescope and what your expectations are. Then check your wallet for $$$. Small, portable telescopes are perfect for some things and large telescopes are perfect for some things. So, determine your requirements first; then we can help guide you.

Subject: Planetary scopes Sent: Tuesday, October 30, 2001 19:30:40 From: firstname.lastname@example.org (John M) I want to get a telescope to view mainly planets. Whats the best scope to get thats affordable, as opposed to the ETX-70, since this scope is best for other than that.Mike here: The ETX-90EC or larger makes a fine planetary instrument, depending upon your expectations and what you can afford. You might even enjoy using a Dobsonian. The larger the scope the more magnification you can get, subject to limitations of the instrument and local viewing conditions.
Subject: Online maps of the moon Sent: Tuesday, October 30, 2001 17:03:46 From: email@example.com (Alwyn Botha) I visited your Meade gallery. I made two photographic maps of the moon available (for free) online at www.moon-phases.com/ This website also has 300 quizzes about these maps of the moon. Each question has a small picture of a part of the moon. You have to identify craters, rills, mountains, etc. You are welcome to link to any of these maps of the moon - or the website itself. I have other educational astronomy websites too - some are listed below. Thank you. Alwyn Botha www.moon-phases.com www.the-solar-system.net www.the-planet-jupiter.com

Subject: LEONID METEOR SHOWER REVISIONS! Sent: Tuesday, October 30, 2001 9:09:23 From: firstname.lastname@example.org (Clay Sherrod) I wanted to let everyone know who has had difficulty logging onto space.com to access the five-part series I have done on the Leonid Meteor shower that they have fixed the problem and you can access the FIRST of the series at: www.space.com/spacewatch/index.html This is an easy-reading series for the general public and walks you through the history, the origin, predictions for 2001 and observing tips for November 17-18. Also note that there is an extensive review of the Leonids appearing on this ETX web site as well. REVISED NUMBERS: estimates from Australian astronomers have revised the peak of the meteor shower to favor LESS the United States and more the western Pacific rim, where 8,000 to 10,000 per hour are expected. Although exact numbers are not given, U.S. observers west of the Mississippi River should expect at least 2,000 per hour (hopefully more) in a peak that I am predicting will hit around 4:15 to 4:45 local time.

Subject: quickcam Sent: Tuesday, October 30, 2001 8:38:07 From: Albert.Mennone@yale.edu (Albert Mennone) I'm interested in modifing a quickcam/webcam to use with my ETX125. I was wondering if you are aware of a review or comparison of available models especially with respect to light sensitivity and chip size. I want to control it from my powerbook (Mac) via a USB. There is a lot of info at your site from quickcam users, but It seems as though there are many types being used with varied results. Great job with your site! Thanks Al Mennone Research Associate Yale University School of Medicine Department of Internal MedicineMike here: Yep, there are several models of Quickcams and web cameras. I'm not aware of any specific comparison resource. You might search the web using Sherlock.
Subject: leonids - photographing with the ETX Sent: Tuesday, October 30, 2001 2:36:45 From: firstname.lastname@example.org (Clay Sherrod) The Leonid meteor shower is expected to peak in only about two weeks so observers should be making plans on how and where to observe what may be a once-in-a-lifetime event. The ETX scopes are IDEAL for piggyback meteor photography; since meteor showers are best seen with the naked eye, why not put that ETX to good use and strap a camera onto it via a good piggyback mount, such as those reviewed here from Scopetronics or find some other creative way to attach. This allows for the meteors to be caught on film with a wide angle (50mm or 35mm or wider lens) view, while star images of the constellations will remain fixed and not streak. Merely set the camera lens wide open (f/1.8 or f/2.0, for example) and turn the focus to infinity. Use the fastest film possible and begin a new photo every 10 minutes to prevent reciprocity from ruining the picture OR if you think you have captured a bright Leonid....stop and start anew. I am sure that Mike Weasner will welcome your photographic contributions to this site if you are lucky enough to catch one of these. By the way, the latest estimates on the storm are calling for about 3,000 to 2,500 in the United States, Canada and Mexico, while about three times that many are expected down under and in the western Pacific and Japan! Tune in for more!! P. Clay Sherrod - email@example.com Arkansas Sky Observatory www.arksky.org
Subject: Dew shields, eye pieces Sent: Monday, October 29, 2001 21:25:56 From: firstname.lastname@example.org (darkjc) I have a ETX-90RA model M. I was wondering if its worth buying the Meade dew sheild or is there a better one out there. If so, could you tell me how I can get it. Also I had a question about eyepieces. I have a 26mm and a 9mm eyepieces. What do you reconmed me geting next, and what brands, I like to look at nebulas, such as lagoon, Orion and may others. I also like to look at the major planets and sometimes faint galaxys. I thank you for any help that you can give me.Mike here: Dewshields are effective in some environments. Whether you should buy the Meade one (which I have but not yet written up) or one of the other types (see the Accessory Reviews - Miscellaneous page) or make one yourself, is up to you. Regarding eyepieces, see the Accessory Reviews - Eyepieces page as well as the Buyer/New User Tips page for some suggestions.
Subject: ETX-125 finderscope screws Sent: Monday, October 29, 2001 20:53:50 From: email@example.com (B.Boulware) Braved the cold last night (mid 30s) to observe the moon for about 20 minutes and try out the Meade lunar filter I bought. Very happy with it. Afterwards, I was looking over the ETX after it had come back up to room temp. I noticed one of the nylon finderscope screws has a decided curve to it. It looks like the screw tip has moved from where it should be. Not sure how it happened but looking at it I am sure the alignment is now off. I remember not being too tickled about these screws when I first brought the scope home. Is there a replacement nylon screw available locally (Lowes, etc.) or do I need to call Meade for a replacement? Been a regular to your web site for over two years. Keep up the good work! -Bobby
Subject: Fixing the Zero Declination Angle Problem Sent: Monday, October 29, 2001 11:43:42 From: firstname.lastname@example.org (W. Falicoff) I have read the FAQ concerning " My Declination (altitude) setting circle is off, what do I do?" Could you please be more specific in telling how this is accomplished. What are you referring to when you say loosen the knob on the DEC scale fork arm? Is this the vertical lock knob (number 6 on figure 1) as shown in the manual. Is the vertical lock the same as the DEC Lock? Is this the same as the "knob on the DEC scale fork arm"? I only see two plactic knobs on this mount that relate to declination. The first is the vertical or declination lock # 6 which engages and disengages the motors. The second is the plastic knob on the side with 0 degree pointer to the declination angle. What I did with my telecope was to loosen # 6 and turn the second one (with the numbers on it) until it the 0 degree decination pointer lines up witht 0 degrees on the dial when the axis of the OTA is horizontal to the base of the telescope. It took some force to turn the dial to accomplish this. Is there some other adjustment knob I have not seen on this telescope? I bought a second telescope for a friend and want to work out any problems with my unit before I give it to him as a present. Mine seems to be working fine now but I don't want to ruin the telescope using an improper method of adjustment. Sorry for the length of my communication. I guess a picture is worth 10,000 words. Mr. W. Falicoff San DiegoMike here: You got it right. The DEC (or Altitude) Scale knob is on the fork opposite the lock. It is the big round knob in the middle of the dial.
Subject: Question Sent: Sunday, October 28, 2001 23:23:31 From: email@example.com (David A. Wortz) I have a couple questions for you, and to be honest I felt a little foolish making a post on your site, so I hope you don't mind me e-mailing it to you directly. But you seem to be the right guy to answer these questions so here we go. I recently bought a Meade ETX-125, and just have some basic (very basic) questions about what it is I can actually see with it. I have beginners knowledge of the night sky, where the planets are, and some galaxies, things of that nature, but what I am unsure of is what it is supposed to look like when I see it in the scope. On your site I see people with the same scope that I have, but they have beautiful color photos of say, orions nebula with blues and reds. When I look through the scope at orions nebula, I see nebulosity, but it is just a fuzzy white structure around the stars. I am curious if color is visible through the scope, or if it has something to do with the fact that the photographs they are taking are altered by adding color to them later. Also andromeda galaxy, for lack of a better word is just ugly. Nothing more than a blur of faint light, absolutely no definition at all. My first concern was that maybe the optics of the telescope were messed up in some way, but Jupiter looks beautiful, and can easily see four moons and at least four or five bands, Saturn's rings appeared crisp and a couple of nights ago I could slightly make out the cassini division along the sides of the rings, so I ruled out faulty optics. This has actually been kind of upsetting to me, because the pictures on your site of some of the deep sky objects were what ended up being the decision maker to buy this scope. My main reason for buying this scope was to observe the objects the way they looked in the pictures on your site, but so far this has been a pretty disheartening experience. Although it has been a lot of fun to scavenge around the sky looking for star clusters and such, galaxies and nebula, have all just appeared as fuzzy blobs, and all together not very exciting. I was curious if this is just the way they are supposed to look and I was expecting too much from the scope, or if it is possible that something is either wrong with the scope or something I am doing. Not having ever looked at these objects through a scope has been a draw back, because I have no basis for comparison and no knowledge of if what I am seeing is good or not. Any advice or suggestions would be greatly appreciated. I thank you in advance for your time, I hope this was no inconvenience to you. Sincerely, Dave W.Mike here: Yes, most nebulae and galaxies appear as what I call "faint fuzzy blobs". Photographs will show more than your eye will see, both details and color. Most nebulae will appear greenish, with some shape to them. Galaxies will be similar, with the shape being the most obvious characteristic if they are large enough to show a shape. The larger the telescope the more you can see so keep in mind that a 5" telescope is more limited.
Subject: Quick question? Multiple cameras piggyback on ETX Sent: Monday, October 29, 2001 2:35:50 From: firstname.lastname@example.org (Jay Friedland) Great site! Here's my question: I'm traveling to see the Leonids and I want to set up an simple camera array and track it (see delpsurf.www.cistron.nl/haas_array.html for the idea!) I'm going to use either 3 or 4 Canon T70s w/28mm lenses. My choice for a mount was going to be a Barn Door tracker (see google: trott "type 4" for the best designs) but then I saw that Costco has meade ETX60s for $128 bucks! Could I build a bar and counterweights and run my 3 cameras on top of the little pup or would I be crazy? Please let me know what you think! Thanks, - JayMike here: Well, you can add a camera piggyback on the ETX-60AT. But four? Depending upon the weight and orientation you may or may not have tracking problems. The most likely problem will be that the locks will slip, ruining the tracking. But if you try it, keep in mind that you will need to track in Polar mode.
One final question - do you have any feeling for how much weight the ETX fork can handle (again with counterweights). Thanks so much!Mike here: Not specifically. It can handle a single camera along with the ETX telescope itself. But the locks won't handle a piggybacked ETX on an ETX, at least not a -90 on a -90.

Subject: Lunar photos Sent: Sunday, October 28, 2001 11:48:31 From: email@example.com (Ken W Anderson) I had a question about lunar photography. In your judgement is black and white with a polarizing filter or color iso 100 with polarizing filter better for taking pictures of the moon.Mike here: Since there is so little color visible on the Moon, certainly B&W can do the job. However, if you want to try to capture the Moon's "color" you'll have to use color film.
I was just wondering if there was a differance where detail is concerned and whether or not a moon filter will make a differance.Mike here: A moon filter will help reduce the possibility of overexposure with faster films (or some digital cameras). And yes, B&W film is typically finer grain than color, so more details can be captured (depending upon the telescope and seeing).
Subject: re: dusty flip mirrors Sent: Saturday, October 27, 2001 20:13:32 From: firstname.lastname@example.org (Richard Seymour) To: email@example.com short answer: Don't worry too much... the dust you see is in a fairly inconsequential spot in the light path. Therefore it won't hurt your image anywhere near as much as a poor cleaning job might. The mirror is "front surfaced"... the reflective coating is waiting for physical damage without taking proper care. Camera stores rarely deal with front surfaced mirrors, hence they may damage the mirror trying to clean it. Read thru the archives of Mike's site, especially the Telescope Hints for articles by Clay Sherrod on cleaning things. It certainly -is- possible to clean the flip mirror, but it isn't easy... if i were going to clean mine, i'd disassemble the rear of my ETX90 so that accidents with cleaning fluids even pure water) wouldn't wreck something else. Find (in your library) books on Amateur Telescope Making, and read their chapters on cleaning and coating mirrors... then you'll at least have the full story with which to make your own decision. Dust is temporary and (usually) inconsequential... scratches last forever (or until you have the mirror replaced/recoated) good luck, take care... --dick

Subject: Reflector or Refractor. Sent: Thursday, October 25, 2001 19:54:25 From: JOHNSPAAR@prodigy.net (JOHN E SPAAR) I currently own a Bushnell "Voyager 760" and a Galileo astrophoto system. I have a chance to purchase a Polaris DS 114 Alt-Az reflector with autostar for $248 or a Polaris 60At refractor with autostar and claiming 565 power over the reflectors 325. I know the reflector has more light gathering and I would like my daughter to see a little more than the moon or mars. I have heard some of the relflector tracking problems and I have a friend who has the Saturn 114 from Meade and has going through 3 autostars including the last one driving vertical over the top and needing motor rework. Meade of course is very happy tosend another and the present one has been running for 3 months. I am torn and not sure which way to go. Help is appreciated. JohnMike here: Well, remember the max theoretical magnification formula: twice the aperture in millimeters. That blows out "565X" for a 60mm telescope. Yes, you could do it but you would be VERY disappointed in the results.

Subject: I really need some advice - ETX70 and dust related issues. Sent: Thursday, October 25, 2001 5:11:11 From: firstname.lastname@example.org (Monty Coward) Greetings Mike, First of all, if anyone else other than Mike has some input, I'll really appreciate it!! Yesterday evening was perfect ... nice clean atmosphere and showing my youngest daughter the value of appreciating the Moon. I changed eyepieces ... and as doing so, looked at the mirror as the EP was placed in the holder. I was horrified in as much that there "seemed" to be a lot of dust on the mirror. On completion .. that is .. later and inside I inspected the mirror more closely and found that is was quite dusty. Now, I do not expect you to know what my interpretation is of dust particles is .. but as you can appreciate ... under bright light it looks horrendous. Questions: 1. Is this normal, that is, when changing EP's and general use to gather dust? 2. Is it wise to flip the mirror when not in use ( stored ) .. or when changing EP's. Surely this will help. 3. How much dust is to much? I do not know what to expect as acceptable loss of image. 4. Are there any solutions to these problems? 5. When would I want to sent it to my dealer to clean .. when it REALLY looks caked? 6. Can one vacuum the dust out .. surely by vacuuming (removing the dust) it would work? I thank you in anticipation Montague CowardMike here: Well, I won't respond other than to say that viewing the optics surfaces under a DIRECT BRIGHT light is misleading.

Subject: A few more questions for you... Sent: Tuesday, October 23, 2001 15:16:32 From: Scott9482@aol.com Thanks for your advice so far. I have a few more questions that you might be able to help with. Just to remind you, I have the ETX 125. I've only had 1 good clear night for viewing so far. When I was using the 26mm SP, everything was crystal clear (Jupiter and Saturn were amazing). However, when I put my 9.7mm SP in, I was extremely disappointed. Everything was very fuzzy. I hear everyone talking about seeing the Cassini division etc., all I saw was a dark fuzzy ball. I went back to my 26, and the image was nice and crisp! But I want Jupiter, Saturn, and Andromeda galaxy to appear as they appear on the back of the box. I have read most of the comments on the ETX 125. I was just wondering, which eyepieces and combinations do you recommend I get. Because the 9.7 was very disappointing. I need more power than the 26, while maintaining the crisp, clear quality image that the 26 gives... Any suggestions...Mike here: Not gonna happen with almost any telescope for visual observations. Yes, the 9.7mm can give nice views, depending upon the atmosheric and telescope stability. Remember, you are not only magnifying the planet (or other object) but the airmass between the eyepiece and the object! You can use a 2X Barlow Lens with the 26mm eyepiece to double its magnification but even then you will lose some clarity.
Subject: ETX telescope Sent: Tuesday, October 23, 2001 8:40:10 From: email@example.com (Gary Adams) My name is Gary Adams. I just found your web site and have been enjoying it. I'm new to astronomy, and own an older ETX telescope which is in excellent condition. Is it possible/economical to retrofit this telescope with an Autostar controller and an automatic focuser? Thanks for your time. GaryMike here: See the "How do I upgrade to an EC (Autostar capable) model?" on the FAQ page.
Subject: What is the difference... Sent: Tuesday, October 23, 2001 3:29:40 From: firstname.lastname@example.org (Fred & Rose Lieberman) I am really enjoying your website. What is the difference between ETX 90 RA and the ETX 90 M? I appreciate your answer. FredMike here: They are the same. This is the original ETX model design from 1996.
Thank you for the reply. Do you have any idea when they stopped manufacturing the ETX 90 M? Also, were the quality of the optics in the 90 M the same as the ETX of today? I do appreciate the help. FredMike here: Same optics as today's model. And I don't know if Meade has actually stopped making the original ETX model. There does seem to be a market for it, at least until the price of the ETX-90EC comes down further.
Meade is in the process of discontinuing the astro model (RA & M). I think it is a good entry model for those who cannot afford the EC. What I like about the ETX 90 is the portability. It is a great scope. If they substituted the 8x finder for a 1x finder, they would have the perfect beginner's scope at a more affordable price. Then, for another $200, they could make the EC base available to anyone who wants to upgrade it. Since that base is already available, they do not have to create anything new. The profit is still there. Anyone can change the base on their own. They do not have to be a rocket scientist to do it. Chan Sing's photos of Saturn http://www.weasner.com/etx/guests/guests_planets.html shows the true potential of the scope. They impressed me. I also took a look at his site. I would recommend that site to anyone. Fred

(Part III) by: valblatz (M/Brampton,MI) 10/22/01 10:10 am I am going to give a 100% "hell yes" to Clay Sherrod's "Supercharge" service for the ETX. I have had 3 chances to use it since it was returned and it is in much better shape than ever before! Although I didn't keep track of exact numbers for finding objects, with the Autostar I would say it was in the 85-90% accuracy range. That is to say it put the object in the low-power eyepiece that many times. I would say that I looked at approximately 40-55 objects in the three trials. This is much better than it has ever performed. I would say this is what you should expect from your ETX/Autostar combination. Also as I noted in an earlier post, the tracking is much better. A few things to reiterate: Your scope MUST be as level as possible. The better this is done, the better the accuracy I have found. Use your low-power eyepiece (I Have been using a 40mm Super Plossl)--things are much easier to find! I have taken Dr. Sherrod's advice and am not relying on batteries. Near home I am using a 12v power supply and when I take it on the road I am going to use the auto-power. In short for the $185 I spent it is WELL worth it. If you think you need this service, Dr. Sherrod's e-mail is: firstname.lastname@example.org or go to: http://www.weasner.com/etx/techtips/tuneup_service.html Let me know if anyone out there gets (or has gotten) this service!

Subject: International Dealers Sent: Monday, October 22, 2001 0:32:27 From: email@example.com (CWC) Thanks so much for your prompt response which immediately solved the problem. Meade did rather poorly on their manual. The situation I was stuck in should be avoidable, if a notice was made in the first page of the manual or on a separate page. I am starting to enjoying the scope. Thanks to you. May I bother you with another problem, which I also raised to Meade by fax (Cannot imaging a company like Meade not having an email address for customer supports - at least not listed on the web site): I bought my EXT-60At at Costco in Taiwan. Then when I looked for some optional accessories, such as hard cases, tripod, and extra eyepieces, none of the dealers (including Amazon.com) can ship them internationally. I do not know what and whose policy dictates that. Any way, do you know any companies who ship Meade accessories internationally? Taiwan does not have a Meade distributor/dealer (according to Meade's web site). Best regards, CartonMike here: Meade is not the only company NOT providing email support. And there are international dealers. See the dealer section of the Astronomy Links page. I don't know which of them will ship to Taiwan.

Look forward to your reply. Sharon Winton ...email...email@example.comMike here: Both telescopes are fine when used for their intended purpose. The ETX-70AT is a good wide-field instrument with limited magnification capabilities. The ETX-90EC is an excellent general purpose telescope, with good magnification capabilities. Both are portable. But the ETX-90EC, Autostar, tripod, and case will cost more than for the ETX-70AT system.

Do you know of anyone that might have tried these side by side to compare? Is the Nagler worth the extra money? I am trying to think of the future in that I might someday have an LX200 also. Any help would be useful as there are no places to try these out in Cumbria, England.

Whereas there are some difficulties using them for astrophotography (but certainly it is being done), the brighter daytime viewing using these will likely be satisfactory to you.
i want to inquire about some informations about etx70et. im searching for a way to operate etx70 from far. display the image at pc or tv screen! [color-bright-clear]same as i see it by eyepieses. remaining at the view on land with no need to move only when i need to change the view. second. can i use the Camera Support Bracket to any kind of video camera? video camera with a video out signal cable that plugs into any standard video device such as a TV monitor, computer, VCR, etc. for example: like any standard securety camera! looks By positioning the camera lens directly over an eyepiece. is it possible to do something like that.? anyway i live in a high place and i have a nice view around me. so i want to use it for land view only. i donot have etx yet but im willing to buy it if its will fits my needs. thats all for now. i need your advice with lots of thanks. sulaiman othman.Mike here: (See my above comments) Yes, you can use a Scopetronix Universal Camera Adapter to hold a video camera but only really lightweight ones. Otherwise the axis locks will slip.
thanks for your answer . but what about if i need it at night? and what do i need to buy? thanks a lot. sulaiman.Mike here: See the Accessory Reviews - Astrophotography page as well as the Astrophotography page.

Subject: The Mighty Supercharged ETX-125 Sent: Friday, October 19, 2001 3:41:28 From: firstname.lastname@example.org (Dave Adriance) To: email@example.com Hi Clay, Had a wonderful night last night and just had to write you about it... The evening looked like it was going to be clear, and today is a national holiday here in Kenya, so I set up the scope on the balcony and got ready for a night of viewing. Sagittarius is still fairly high in the sky down here, until around 21:30 or so (gets dark by 19:00), and last night there was no moon to speak of. After two-star alignment, I proceeded to go through the entire list of Messier objects in the Sherrod Observational Guide for Sagittarius. Out of 20 objects, the ETX put 18 of them within the field of view of my 26mm eyepiece - and the other two were just outside the edge! I could have thrown my finderscope away and it wouldn't have made a whit of difference. Not that I'm going to, of course, but last night was a vivid testimony to the benefits of supercharging one's scope... as well as one's enjoyment of the night skies. Best regards to you and yours, D.____________________ Dave Adriance

Subject: Thanks again and..... Sent: Wednesday, October 17, 2001 19:55:17 From: email@example.com (Frank Tralongo) Just a quick note to again thank you for your recent help with the 494 autostar. BTW your ETX site is GREAT!!! I also have 2 more questions: 1. Do you run an EXT club and if so how would I go about joining? 2. Been thinking of getting a second scope, the three I've been kicking around are the 90mm ETX, 102ETX and a 127ETX. I love the portability of the 90mm and the ST reviews were great but I am not sure it's "a big enough bucket". The 127 ST review seems to be saying something between the lines ie. not quite as optically sound as the 90mm. And haven't found any reviews on the 102. Since there are no clubs in town I've never had the chance to view through any of them my only info is through word of mouth, ST reviews and those with ETX experience. Most of my use would be backyard viewing stars and planets some limited deep space with possible future ccd photography in addition to dragging the scope with me on rv trips. BTW I love the goto technology, any suggestions/comments on a direction I should lean? When I lived in San Jose I had an 8" F6 reflector on an EQ mount which was soo big and heavy that I found any excuse not to drag it out, plus the darn city lights were a great source of frustration. Here in Kanab Utah I'm within 20 miles of pure desert darkness but I can be a tad lazy .>:) PS Also loved the reviews of the LX90 8 inch, sales types tell me this is the one but my fear is this might fall into my old scope's catagory Big Heavy and unused. Warmest Regards, Frank firstname.lastname@example.orgMike here: The ETX-105EC falls into the almost nearly as portable as the ETX-90 whereas the ETX-125EC goes into slightly less portable than the ETX-90. Certainly you get more light gathering power with the 125 vs the others so you have to make a trade-off. Optically, the ETX-125 is good (the older reviews cite problems with the initial batch). As to a "club", nope. Just the online community. Although we did have our first "Annual Mighty ETX Star Party" last month. I hope to continue that once a year, moving the location around the country.
Subject: leveling tripod Sent: Wednesday, October 17, 2001 13:46:04 From: email@example.com (gary) I'm new to Astronomy, and i need to know what is the proper way to level the Tripod. I have tried to use a level but there is no place to really set it to show true level. If the scope is truned (even tho it reads level on top of the tube) it will not align up with any of the alinement stars. The sope is level and pointed north, but the Tripod is not.. This is really getting to me because i cant track anything. Please help me.. thanks Gary.. PS. Great site...Mike here: Couple of points. If the telescope tube and base are horizontal but the DEC (or Altitude) scale does not read 0 then the scale is off. See the FAQ for adjusting it. Or you can ignore it if you just eyeball the leveling and use an Autostar in Alt/Az mode. The same applies to leveling the tripod. I usually just eyeball it and let the Autostar compensate (which it does once aligned). But if you really want to level things, put the ETX on the tripod and place the level on the flat portion of the ETX base. Then you can orient the level in several directions to ensure "levelness".
Subject: etx-60at or 70at do these scopes come off? Sent: Wednesday, October 17, 2001 10:58:49 From: firstname.lastname@example.org do these scopes come off of there mounts? Can the mount attach to a 1/4 20" thing. Also, what is the difference between the m AND ra MODELS OF THE ETX ? aLSO, DOES THE ETX 90 M & RA COME OFF THEIR MOUNTS? hAIMike here: The ETX-90 models can be removed from the fork mounts for use as a spotting scope. However, the ETX-60 and -70 models are not intended to be removed and remounted. It can be done but you run the risk of damage. The ETX-90 Astro M and ETX-90RA are the same telescope. This is the original model ETX pre January 1999 and is not upgradable to the EC/Autostar capable model.
do the etx-90 models come off via a 1/4 20 screew off their mount? i.e. can I mount a camera on the etx-90 mount.Mike here: The ETX-90 has eight small hex screws that you remove (4 on each side). Then you can attach the telescope tube to a tripod using one of the two standard photographic tripod mounting holes on the bottom of the tube. Yes, you can attach cameras; see the various astrophotography pages on the ETX Site.

The ETX125 came like this...should I take it back to the Store or Contact Meade ?? Thanks BillMike here: What you do depends upon WHAT kind of spotting you are seeing. If it is anything except for having been caused by moisture, return to your dealer for an exchange (assuming still under warranty). If due to dew or other moisture, see the "Cleaning Optics" article on the Buyer/New User Tips page.

Will be looking for the "Mad Bull of Crete" as soon as we have less cloudy skies here in SE-MA. Thanks again Clay. I would also like to mention to the group that my last modification to the ETX125, of which I noted on this user group several months ago, is still working like a charm. The -125 is now a real pleasure to use. A total of about 20-30 outings since my 'mad' modification. Trying to align the DSC's on our PDHQ 12-1/2 so that my wife and I can make our second round of the skies more informative and breath-taking. I can't help but ask myself "Where was I all my life"? What a heavenly sight the heavens are. Take Care Blais Klucznik email@example.comAnd:
From: firstname.lastname@example.org (Clay Sherrod) Thank you so much Blais....I truly hope that many observers enjoy the Constellation Guides; with nearly half of them done now, there are many folks out there using them for very productive observing...some colleges have even written to me expressing a desire for support materials as they are using some of these in observational astronomy classes. Glad your modification is successful....you have put a lot of work into the scope and now you are reaping the rewards! Always good to hear from you! P. Clay Sherrod

Subject: Kochab's Clock Sent: Sunday, October 14, 2001 16:29:13 From: DonMcClelland@webtv.net (Donald McClelland) As most people that visit this site know, Clay Sherrod has contributed tremendously. He's most famous for his Supercharge Service to the ETX family of scopes but he also has outstanding observational suggestions. Who better than a retired professional astronomer! I recently received a new Questar. I came into some extra money and always wanted one and took it to a star party last night. It tracks in Polar mode only so I needed to align it properly. I used Clay's Kochab's Clock method to find the true Celestial North Pole and boy did it do a great job. I've always hated the thought of using manual setting circles mainly because I didn't think I would align it well enough. Of course accurate Declination was important to align the setting circles. I matched a bright objects (M8) RA setting and for the rest of the night had no problem finding things. Naturally tracking was absolutely perfect (for visual use) and Polar alignment probably took less than 5 minutes. Thanks Clay and keep up the outstanding work helping us all out! Don

Subject: Dr. Clay Sherrod and the "Supercharge" service Sent: Saturday, October 13, 2001 14:49:52 From: firstname.lastname@example.org (Mike Greenzalis) I wanted to take a moment to let your readers know about a special service and a special person. Recently, my LX200 8" made the trip to Conway Arkansas for Dr. Sherrod's "Supercharge". My LX200 was purchased after approximately four years of gentle use and it looked great but I still wanted know how it was performing mechanically and optically. Dr. Sherrod performed the service, kept me up to date and sent it back expeditiously. What happened next would make anyone "cry". The shipping service delivered the LX200 with a hole in the side of the box! A rod had punctured the box and hit the focus knob square. Thank goodness for insurance as Dr. Sherrod stood with me to persuade the shipping service to pay. More important, Dr. Sherrod encouraged me to send the LX200 back to see how bad it was and if it could be salvaged. I received the scope a week ago and am thoroughly enjoying it. Thanks Clay! I offered to pay him for his time and the work performed but he refused for a promise of a pizza next time I am driving through Conway! I hope to "pay-up" some day soon. What tremendous service and commitment! Keep it up Clay and thanks again! -- Mike Greenzalis Southborough, MA email@example.com

Subject: Goober tackles the ETX-125 tune-up Sent: Thursday, October 11, 2001 20:23:18 From: email@example.com (Ronald Bacon) After reading the instructions on how to do the ETX-125 tune-up, I though to myself " No sweat, I can do that in an afternoon and fix some of those slop problems ". I should have known not to mess with it . . . I was already having a bad week. I forgot, somehow, to turn off the power on my kid's computer before unplugging the video card. He was happy about getting a new computer though. Stuff I had ordered from a supplier in the midwest for a client was somehow "delivered" to the wrong address, causing a two week delay for the project. Things had been going wrong all week, but hey! This would be fun, and a snap really. Got all the way through the instructions and was on my way to reassembly, when I was called away to dinner. When I came back, I was short about a quart of blood in the brain (the digestive process you understand) and I could not for the life of me remember how the base motor was suppose to be plugged into with the four wire plug. So I figured, "Well, just follow the curve of the wire, dummy, and let the plug fall naturally in place." Did that, and guess what? It didn't work. Oh nuts . . .visions of dead video card's in my head, I now have to wonder if I have reversed the plug. And now I notice that you can turn the thing end for end and have a different color coded sequence of wires plugged into pins one through four. Why oh why didn't I finish the wiring while it was fresh in my head, instead of going to dinner? Or at least right it down? Nothing is so bad that you can't make it worse, so of course I tried every combination of plugging those wires in that I could think of: reversed the leads, reversed the fork arm bundle, switched fork arm plug with base plug, etc. No go. Must of fried the encoder boards. Great. So I take the OTA and mount it to my Bogan tripod for the next month, while I try to save up the money to send it to Dr. Sharrod. In the mean time, I take the drive apart again and go through it in a very methodical way, taking notes as I go. I put it back together - still dead, with no motor movement at all. Autostar is happily saying everything is working, while I am looking at a dead mount. Great - this is really affecting my confidence. Wife is asking me to start working on the deck, but I am - by now- certain that I will slice off my arm with the circular saw if I start work on the deck. In despair, I call Dr. Sharrod in Arkansas, and he spends almost 45 minutes on the phone with me talking through various procedures trying to get the mount to work. We narrow it down to a loose wire, a bad power distribution board ( what you plug the Autostar into ), or a twisted and broken bundle of wire going to the fork arm. Tells me to try all the plug connections again and to check the continuity of the bundle going to the fork arm. So . . . I check the continuity of the fork arm bundle - all OK. Try all the plug connections again ( pins one through four on position one through four on the moulded plug ), but this time I turn the plug that goes to the base motor upside down ( wires facing away from the power panel , actually making a loop over the top of the plug). I had done this before with no joy. Guess what? The motors started working! One reversed plug had shut down the whole scope. Wow. Called Dr. Sharrod, and he asked me to post this sad tail. I guess he wants you to know that with perseverance you can fix many of these things yourself. I mean, what the heck -it's already broke, try it and see what happens. It looks like you can plug in the plugs completely wrong and not blow it up. You might not be able to say the same about the inside of the Autostar or messing with the actual circuit board of the encoders though. Now . . on to the deck!

Subject: ETX 125 The value of a supercharge. Sent: Thursday, October 11, 2001 19:46:56 From: email@example.com (D. Ray East) I am totally amazed at what Dr. Sherrod has been able to do with An ETX125EC that I sent him. Not only was the work fantastic but he was able to do all of the work in less than Two months. This was including the fact that he sent the scope back to Meade as well. I cant imagine just sending the scope to Meade and getting it back in that period of time let alone sending it to Meade and then doing his 83 point inspection that he does as well. Shall we get to the nuts and bolts of this. I own a machine shop. The reason I sent the scope to Dr. Sherrod in the first place was to see what type of work was being done out there. If I felt that the quality of work was not up to my standards I might have decided to go into the scope upgrading business. As it is not only did the scope come out that good. It far surpassed any work I have seen by anyone in this field. After spending several nights now checking everything I could think of to check. I have come to two conclusions. This has to be the all time best ETX125EC I have ever seen and the work done by Dr. Sherrod has made it so right out of the box so to speak. It will cleanly split many double stars. High power with the small column of air it views through makes this scope a wonder at higher powers. Granted Living in Redding CA I have some of the best viewing condition available. (That is why when I retired I moved to Redding.) Saturn at higher power is a very wondrous sight to behold. I bought the ETX125EC to hold me over till the LX200gps was released. I having just sold my LX200 12 inch scope. With the fantastic work done on the ETX I have decided to send my new scope to Dr. Sherrod just as soon as I receive it from Meade. I will of course check the scope to make sure it is up to par at least. Then I will also avail my self of Dr. Sherrod's knowledge of how good the scope really is. If it takes 6 months to get it right that is fine also. Still knowing what miracles he has performed so far I doubt it will take more than a few weeks. Now you ask what I am being paid to come up with all these fine comments. I will tell you. I now own one of the finest ETX's around and that is payment enough. Thanks again Clay for all the fine work, upgrades and care you gave my newest possession. dray * * * * * * * D.Ray EastAnd:
From: firstname.lastname@example.org (Clay Sherrod) Ray - thank you so much for those wonderful comments; just having the scope working again was reward in itself for me and this is the frosting!

Subject: Help please Sent: Thursday, October 11, 2001 8:51:31 From: firstname.lastname@example.org I think that I might caused a bit of a problem. I purchased a new ETX 70 and noticed that their seemed to be a lot of dust on the inside of the telescope when using a flashlite. I took the tube apart and flushed it out with warm water and some w/p liquid. I do not seem to be able to clean the main glass properly or get al the water out of the tube. Do you have any suggestions.Mike here: Well, you would probably have to disassemble it for best results but as long as there is no spotting on the optics (or rusting of metal) then letting it air dry for several days may be the best. Alternatively you could contact either Meade or Clay Sherrod for cleaning. If you open up the tube you will void the warranty and you may find it difficult to reassemble it correctly so don't do that.

(here in Seattle it'd be "Display and Costume", for example). They have clear styrene balls (two half-spheres with a joining surface) in a wide variety of sizes... and if they don't have it in stock, they can order it. There are also (at builder's supply warehouses) "Sun Tubes"... a skylight system consisting of a clear dome above a Sonotube which passes from your house's roof down to the living spaces. Somewhere amongst the ETX90 web-ring (see the bottom of Mike's page) is a (theoretically) web-accessible ETX90 with camera... that system must be in a dome, so email to the owner might shed light...

Subject: ETX Dome? Sent: Wednesday, October 10, 2001 16:52:34 From: email@example.com (Charlie Coburn) I have come across your site twice in the last couple of weeks. First as the result of a search engine, and today at the suggestion of Meade's Tech support staff. An astronomer friend of mine told me that he had seen a Plexi-glass dome for the ETX. He said it was available from Edmund Scientific for about $100.00. Well... Now that I have told someone I can do a remote camera system for them, I can't find the dome anywhere. I am looking to house the ETX inside a weather tight housing. There will be a video camera mounted to the scope, and it will be mounted on the roof with the controls inside the building. Targets are all terrestrial, so Elevation isn't really important. Any ideas? I'm about to run down to TAP Plastics to see if they can fabricate anything like this. (Maybe a clear cake serving tray cover wouuld work! ;) ) Another option would be to make a housing that could travel with the OTA and camera while leaving the Azimuth mount protruding below. As you can see a clear dome might be the ticket. If I have to fabricate something, I'll let you know what worked. Any Ideas you have would be appreciated.

Now Im writing a comprehensive article for our association journal. Amongst other facts Im very interested to show all possible data about the Double-Double stars. From all the sources I could find, Im still missing some important values. Ill appreciate very much if somebody will guide me where I can find a comprehensive table including those orbital elements: P - Period of revolutions in years. a - Semimajor axis of the true orbit in seconds of arc. The data that I need must be for each pair of the double stars separately and data relating to both pairs of the Double-Double stars together. I also need the measured trigonometric parallax to enable me to calculate the distance from sun. Ill be very grateful to receive your reply.

Sent: Tuesday, October 09, 2001 2:38 AM Thanks so very much for the great scope you sent back to me. It is certainly much different than what I shipped out to you. I could not believe what those battery's did they were brand new out of the box as well. Just goes to show you what happens with much that is made in this day and age. It is past midnight here I have been out playing as I was up before dawn this morning trying to get some things done. Still it was worth everything to get the scope doing what it could be able to do. I will say this much this little 5 inch scope looks to be able to hold its own with the 8 inch ones I have seen. The moon had just come up and it was just crystal clear. so bright that it hurt your eyes but boy did this scope show off all the little details. The terminator line was incredible. So much to see so little time. As good as the optics are one this scope now I don't think I will ever sell it. I am getting one of the new lx200gps 12 inch one soon as I get my new dome built which I hope is by March of next year. Still I am going to keep this for star parties and such. Many is the time I go over the mountains between here in Redding and Reno NV. It is so clear up at a mile high you can see forever. That and having all the dense trees around there is just crystal clear air. If for no other reason than to make use of the scope for those trips. I have to get to bed now but I will write more later. This scope is fantastic now thanks to you. dray * * * * * * * Ray
Subject: My report on Supercharge service followup Sent: Monday, October 8, 2001 19:52:58 From: email@example.com (Matthew Gertz) I thought I'd take a few minutes to report on a part of the Supercharge service that's rarely discussed (mostly because it's normally not an issue) -- Dr. Sherrod's followup care of a Supercharged scope, which is great. If you could post this testimony on your excellent "Mighty ETX" website, it might answer some questions for people who are thinking about getting their scope supercharged but are unsure as to how problems would be followed up. I bought my ETX-125 EC telescope last February, and although I and my sons were enjoying it, the fact was that there was a lot of play in the gears, and so my GOTO's, though very close, weren't quite on the money. My scope was a perfect fit for Dr. Sherrod's Supercharge service, and so I made arrangements last May to ship the scope to him and get it overhauled. Normally, the story would end there -- satisfied customer relates how Dr. Sherrod kept them informed during the process, updated and trained their Autostar, and so on. Indeed, Dr. Sherrod did all of that, and I was very pleased with how I was kept up-to-date with what was going on. It happens, sometimes, that things sometimes just go wrong, for no other reason that... well, things happen. I got the scope back, and I immediately got derailed from any use of it due to the birth of my daughter in early June. After the dust had settled, I finally got a quick opportunity to try out the scope in early July (this being the Seattle area, my viewing was rather limited due to the late sunsets enjoyed (?) here in the summer, and the unusually cloudy weather we had this past season). I set it up on my porch, let it cool down for a couple of hours, and then tried a two-star alignment in polar mode to get me going. After alignment, I decided to slew over to a Messier object I'd been hankering to see for a while. Well, I couldn't find it. So, I slewed back to one of my alignment stars (Arcturus, if I remember correctly) to see how accurate the scope was. It was way, way off. Not even close. Huh. Well, I ran through my checklist again, making sure all of the values in the Autostar were correct, and re-aligned (Arcturus and Castor, I think I recall). After alignment, I slewed back to Arcturus. No, it was way, way off. After some experimentation, I was able to determine that declination was *dead-on*, but R.A. was off by 2 hours on the slew back. Well, I'd had some AC adaptor problems in the past, so I picked up a Meade AC adaptor, and tried that a couple of nights later. Still bad (which made sense, since the problem was overshoot, not undershoot). Rats! I had some correspondence with Clay on the issue, and I said I'd try a few more tests, but I had to set the scope aside for another couple of months as the baby duty became a little busy for a while. Finally, last month, I was able to take the scope out again. It turned out that the R.A. slop was cumulative -- a loss of 1 - 2 hours per slew, until finally it would hit the hard stop. Clay and I then began a busy correspondence of a half-dozen e-mails a day, with me trying various daytime tests we'd devised together. Clay was very concerned about getting my scope working right, and was right there all the way trying to help me figure it out. After a day, we'd eliminated the Autostar software and the Autostar itself as culprits. That left a hardware issue. There were two possibilities: a clamp failure, or an encoder failure. A clamp failure would have caused this problem simply due to gravity & the weight of the tube, and would therefore affect only Polar mode mostly; an encoder failure would certainly repro in both Polar and Alt/Az mode. I switched it to Alt/Az mode and, voila! Alt/Az was freaking out even worse that Polar mode. Clay asked me to ship the scope back to him, and he would examine the scope further, with no charge to me for the additional labor. Sure enough, Clay was able to determine one of my encoder arrays had gotten fried; my personal guess is that it was probably due to the non-Meade bargain AC adaptor I'd been using -- probably got zapped the second I tried out my updated scope. (The good doctor's reputation, therefore, remains secure -- a bad encoder has nothing to do with a Supercharge!) Clay had some encoders on hand, so I bought one of his (we didn't have to ship the scope to Meade, thank goodness!); he installed it, retested, re-aligned, and rechecked the scope from top to bottom -- essentially doing another Supercharge on the scope. The encoder fix worked, and he shipped it back to me. Seattle is forecast to have heavy overcast for at least the next week; however, I was able to run all of my indoor tests, and the scope performed beautifully -- RIGHT ON THE MARK each time! (Can't wait for the skies to clear... ) Yeah! So, a word from a satisified customer: 99% of the time, everything goes right with a Supercharge -- witness all of the happy customers testifying on Mike Weasner's wonderful Mighty ETX site. Sometimes, just by pure bad luck, though, something might go wrong. Hey, y'know, that happens. No fears, however, because Dr. Sherrod is on hand, and happy to work with you to get the scope working. Allow me to reiterate that, EVEN THOUGH the error had NOTHING WHATSOEVER to do with Clay's supercharge service, it was still important to him that my scope worked for *me*. He worked with me all the way -- he even threw in the labor free on the encoder fix, and bumped me to the "front of the line" to get the work done. He just really likes a satisfied customer, and that's exactly what I am. If you're contemplating a Supercharge, and have been worried about "well, sure, but what happens IF...", well, you can stop worrying. Clay will make *sure* your scope works for *you*, bottom line -- his work is guaranteed, and he's a perfectionist when it comes to telescopes. --Matt--* P.S. Another tidbit for your readers: if anyone's curious as to whether or not the new Autostar downloader program works on the forthcoming Windows XP, I can attest to the fact that it does -- I was able to download 2.2Er via Windows XP (RC1) to my scope during the tests that Clay and I ran, and no workarounds were required. ---------------- Dr. Matthew GertzAnd:
Matt - thank you so much. I wish you some very clear skies soon! I am glad I was able to help. Clay Sherrod
Subject: Tripod Adapters Sent: Monday, October 8, 2001 16:35:38 From: Wryword@aol.com Hi. I've just come across your ETX website, and it is extremely well done and informative. I have a question that if you have the time I hope you can answer. I've not been very happy with the aluminium tripod I have with my 125. I have a much more substantial Meade tripod that I used with an older 4" SCT. It has a wedge and all, but theETX won't mate with it. However, I saw in one of the pictures on your website that someone apparently found an attachment that will let you mate the ETX with the older, steel tripods from Meade. This is just what I am looking for, but where can such a thing be found? Thank you. John HenryMike here: Many dealers carry adapter plates. Try Scopetronix, Shutan, or OPT.

If I could impose one other question, do you think the 125 OTA would be too large of a spotter for a 12" LX200? Gaze On! DaveMike here: Thanks. And the red-dot is a LightSight from Scopetronix. I've seen some pretty large scopes on LX200 models so it could work with adequate mounting AND counterbalancing.

With any scope purchase, they are including a Meade Electronic Eyepiece ($99 value). It is not available for sale separately. I had not come across this as an accessory before. The one on display was mounted in the 45 adapter, although it would fit as any other 1.25" eyepiece (about as long as a Barlow/12.5 combination) Output is NTSC for direct feed to TV, VCR, Camcorder. Didn't see any other specs- other than it provides "monochromatic views of lunar, planetary and other objects" and it has a brightness adjustment. Looked like the chip is about 1/8 x 3/16. Must be battery powered (only had one cable). Doubt it performs like a Pictor1616, but it could be fun for small groups or "remote controlling". Regards, Tom Craig Raleigh, NC

Subject: 883 Field Tripod Fix from Meade Sent: Sunday, October 7, 2001 11:36:24 From: email@example.com I haven't found mention of this field repair from Meade, so disregard if it's already in your archives somewhere. The 883 tripod (ETX90) started seriously slipping after about six-month's use. I recently contacted Meade and they mailed me a set of three reinforcement plugs and instructions for disassembly and installing the plugs. Its straightforward and takes less than a 1/2 hour to accomplish. Basically it consists of plastic plugs that are inserted into the height-adjustment-knob side of each leg. Since these legs are hollow and easily deformed this provides rigidity and tightening the knob is no longer a feat of strength. In short, it works (for now anyway) and I'm a bit happier about the tripod.Mike here: Thanks for the reminder. There is discussion of this on the Accessory Reviews - Tripods page.

Subject: Piggy backed 80mm refractor Sent: Friday, October 5, 2001 20:40:07 From: firstname.lastname@example.org (John Wood) I have mounted a Vista 508 80mm short tube refractor to my ETX 125EC using the Scopetronix Piggy-back mounting ring exactly as John Theodossy suggests. The motors handle the weight with no difficulty. The refractor has a double ring mounting cradle and I had thought that two Scopetronix rings might be needed for stability but this does not seem to be necessary. Focussing the refractor adds considerably to it's length. With a focal reducing lens added it still extends over the ETX eyepiece but you can use this port to hold a ccd video camera mounted in a 35mm film cassette. The plan is to use this to guide the assembly. .....John

Some people recomend the nexstar4 instead of meade......... I think the size will be 3.5 to 5 in. I fly to New York next month and thought I would buy a telescope than, Its much cheaper. If you can give me some good advice I`ll be glad. KentMike here: The ETX-105EC does seem to be a nice telescope but it is slightly larger than the ETX-90 models. The larger size has its good points and its bad points. So, if you more portability go for the -90; if you want more aperture in a slightly larger telescope, go for the -105. Keep in mind that you may not be able to carry either telescope as carryon baggage right now. And the ETX-105EC in an appropriate case may not qualify either.

If you need any help please feel free to write anytime. Regarding home position, alignment, etc., check out all the TECH TIPS on Mike Weasner's ETX site....almost any question you might have will be answered somewhere on that great tool to all astronomers! Great skies and bright comets! Clay Sherrod ----- Original Message ----- Dr. Clay I finally made my mind up to try the ETX-90EC first. I think it will do what I want to do right now and if I stay in the hobby maybe I can sell my 8" Newt and then buy a LX-90. I am afraid to put that much money in one scope right now and maybe the ETX-90 will let me know what I need to know. I sold enough Ham Radio equipment to purchase everything for the ETX that I need so I didnt have to put any money with it and that keeps the Wife Happy :) I appreciate your help and Mikes great site is also a great help. I got a package deal from ScopeTronix and I hope it gets here this week so I can try it out this weekend. Is there anything I should do first when it gets here? I have read alot about training the drives and bad grease in the gears? I hope that im not disappointed in the little scope, I plan to take it on trips and do a little bird watching. I will try some pictures on the moon and planets a little later on but right now im just interested in seeing if the tracking, GOTO and everything works as it should. Thanks again and let me know if I can be of any help to you. Thanks Ronnie
Subject: Image brightness vs magnification Sent: Monday, October 1, 2001 12:49:42 From: Briguy730@msn.com (Brian Gaines) is it good to get a 40 or 50 mm eye pieces for nebular or galaxy sights...will they be brighter or sharper... I noticed that when i put the Barlow in with my 26 mm the image was dimmer and i couldn't resolve it that well at all compared to the 26 mm How much brighter would the Adromeda galaxy be if i put a 40mm eye piece instead of a 26mm Thank u for your web siteMike here: Less magnification reduces the area that the image brightness is spread over. So, yes, the image would be brighter with a longer focal length eyepiece. More magnification increases the area, so images appear dimmer, as you've seen when using the Barlow Lens. Would a 40mm eyepiece provide better views of galaxies and nebulae? Yes, sometimes, but keep in mind that just using a longer focal length eyepiece can not make up for what the telescope by itself can't provide.
Subject: ETX focus control - a $.25 necessary improvement Sent: Monday, October 1, 2001 10:01:31 From: firstname.lastname@example.org (Ted Lin) I have been bothered by the sensitive vibration of the ETX focus knob control, and was thinking about getting a electronic focuser, but was not sure about that due to its price and repeated report about the control issue. While searching for some ideas, I found the famous laundry pin solution, and other adaptive version from the motor control. I also read some info about Scopronic's a flexible wire to extend the control knob, and about how it behave when the tube is pointing right up. I think if I can find a flexible tubing, I can give it a try. I ended up bough a spiral spring at the local Beasy Beaver hardware shop while looking for some plumbing parts. It sells for $.23 cents/foot, and was originally for repairing lawn mower choke/valve control. Took the knob down using the included hex screw and inserted this spiral wire, and insert another screw at the free end for easy turning. Took it out for a test run, and it works beautifully. I guess MEADE should include this $.25 cents wire in the scope. I guess you can use any flexible hose as long as the inner diameter is small than 3/16" (1/8" will be tighter). I think next weekend I will get a good quality rubber vacuum line from the auto-parts store, and that will even damp out the tremble better as compared with the steel spring. Just want to share this with you ETX owners. Ted LinAnd an update:
Well, I picked up at Sear Hardware store one foot of 3/16" Good Year fuel line rubber tubing yesterday, and put on the scope last night. Worked beautifully, much better than the steel spring since it really damp out the vibration from my hand. The tubing has actually 1/8" ID (I guess it is rated as 3/16" because it assume the rubber will give a little, but it fit perfectly on the ETX125 focus shaft. The outside diameter is little less than 1/2", and I really like it since it extends out from the end of OTA, and you hand can just hold it anyway you want, the further away from the shaft, the smaller the image trimmer. When the OTA is pointing straight at Vega, the soft rubber bend gently and has essentially no effect on the turning of the focus. I am not sure why no one has suggested this at all. Try it out, it's only $.93 a foot at Sears, and I used only about 5". Ted
Subject: Eyepiece edge sharpness Sent: Monday, October 1, 2001 9:55:14 From: email@example.com (TLN) Concerning edge sharpness with the 9mm ETX60 eyepiece: I found that the lense in my 9mm eyepiece was loose. I could here the lense rattle if I shock the eyepiece. I tightened (SNUGGED)the lense from the telescope end of the eyepiece using a small screwdriver inserted into on of the 4 slots in the threaded lense retainer ring. Tom Nagy
Subject: ETX 90 RA Sent: Monday, October 1, 2001 5:34:38 From: Dsteele@focusnet.co.uk I bought the ETX 90 RA the other day, used it most of Saturday night and was very pleased with the results. The only problem I had was with the Meade 2x Barlow Lens. When looking at Jupiter and Saturn with the 9mm Plossi it was fine but wanted to get closer. The Barlow took me closer but the focusing quality was rubbish. Do you think if I bought one of the following eyepieces I would get closer and better results for viewing the planets. If so which one do you reccommend. Meade series 3000 Plossi- 5mm or a 6.7mm Meade series 4000 Plossi- 6.4mm Bear in mind I have the 2x Barlow, 25mm eyepiece and a 9mm eyepiece. Many thanks Daniel Steele ie. Does the automatic focuser you can buy only work on the ETX 90 EC version. Because I read on one of your pages you need to focus using the Autostar.Mike here: The Electric Focuser does not require the Autostar; it has its own controller for those who don't have the Autostar. As to using a Barlow to increase magnification, keep in mind that the theoretical maximum magnification for any telescope is twice the aperture in millimeters, or 180x for the ETX-90 models. When you double the 9mm you will exceed that max. You can exceed the max with good quality optical components on bright objects. But you will see some "breakup" or "fuzziness" when looking at planets with too much magnification. Yes, you can use those other eyepieces but you may still be disappointed.
So a 7mm eyepiece should be perfect because it only exceeds 178.5X magnification.
Subject: reassembling the Meade 14mm UWA eyepiece Sent: Monday, October 1, 2001 5:03:39 From: firstname.lastname@example.org (Clay Sherrod) To: email@example.com I saw your post on the Mighty ETX site about your 14mm UWA lens coming apart. You really have a mess and I will try to walk you through it. You will have five (5) components that are actually composed of eight (8) lenses, some of which are cemented into place as a "lens group". I will call each one of these (both the cemented combos and individual lens elements) a number from "1" to "5" STARTING with the group CLOSEST to the EXIT PUPIL, or that lens closest to the eye when observing. You will reassemble ONLY in this order, with the first group needing to be put in first, followed by each other one in succession: group 1 - One of two cemented doublets that will show a concave surface on one face and a convex surface on the other. This is a fairly large doublet, but is the SMALLER of the two (#3 is the second similar group). Place the CONCAVE surface facing out of the eyepiece, or toward your eye. group 2 - a single lens, very large, convex on both surfaces; this is the one that you likely might get in backwards, since in is MORE convex curved on one side than the other; use a tissue paper on the flat surface of a table to determine which side is more curved....the face that has the greatest curve goes against group #1 that you just put in. group 3 - identical to group #1, but this is the largest of all groups; the concave surface is only very slightly concave, and that surface faces the group #2 that you just inserted. group 4 - an easy one to identify, this is a meniscus lens with nearly equal concave and convex surfaces on opposite sides....put the convex side facing the group (#3) that you just put in, or toward the eye end of the eyepiece. Group 5 - another easy one....there is a spacer between this tiny lens doublet and group #4 that you just put in. Put the space inside up against group #4 already in the eyepiece barrel and then insert group #5 with the concave surface facing group #4...this will put the FLAT side of this doublet facing the opposite, or back side, of the eyepiece. Good luck! Clay Sherrod P. Clay Sherrod Arkansas Sky Observatory firstname.lastname@example.org
Subject: shipping etx internationally? Sent: Monday, October 1, 2001 4:38:35 From: email@example.com (Gilberto Cutrupi) Hi I'd like to know if there are any dealers shipping etx scopes outside the States. it seems unbelievable to me that for the same scope (an etx-70), which is sold throughout the States for US$299, in Europe can be found at the "cheap" price of 470 US$, almost the price of an etx-90. I'm aware of tax issues and customs, but these don't affect so much other items like computer equipment for example. Why then penalizing those who'd like to start learning astronomy in other countries? Thanks, GilbertoMike here: I suppose it depends upon the dealer and their distribution agreements. I don't recall seeing any reports however.

Rounds) Here is a link to my AstroPhotography page on my web site. www.jvlnet.com/~drounds/astro.html I just purchased a scanner (after getting the digital camera!), so I was able to scan some of my older photos and post them. The photo of Mars was taken by hand-holding the Canon S100 digital camera to the telescope eyepiece. You may either post a link to the page or download the images and post them on the apropriate pages of your web site. Each image is stored on the web site in two sizes, a small 5-30k image, displayed on the web page and a larger 15-400k image displayable by clicking on the displayed image. Dave Rounds
Subject: Meade Electric Focuser Sent: Monday, October 1, 2001 0:38:12 From: email@example.com (Tatsuo Yamamoto) The 9V battery in Meade Electric Focusers runs out very quickly. I measured the DC current and found out the focuser draws 4mA even if it is not in use. I also found out by detaching the cable to motor unit, it will not draw current. When it is in operation, it draws approximately 30mA. Because of the idele current, battery dies in a few weeks. I am not sure if my focuser is defective or if this is a common design issue. Regards, Tatsuo YamamotoMike here: This was a common report right after the Meade Focuser was released. But thanks for pointing out it for those recent purchasers.
Thanks for the prompt response. Has there been a fix to this problem ? Regards, Tatsuo YamamotoMike here: Not that I recall.
