Subject: Photography with ETX Sent: Wednesday, June 30, 2004 18:19:35 From: DANNY CAMERON (email@example.com) My name is Danny Cameron & I live in Inverness in the Scottish Higlands. I wrote to you before about photography with the Nikon D100 digital camera. Just got a T-Adapter & T-Mount today as well as my Laptop back from repair, going to try some landscape photography with the ETX-105 tomorrow, send some results if any are good. Do you host a Terrestrial photography page on your site? & if not will you be intrested when I finish mine? Bye for now! Danny CameronMike here: Haven't done a specific page for telescope-based terrestrial photography but always interested in the results!
Subject: Trouble with the DEC lock on ETX -90 Sent: Monday, June 28, 2004 15:42:17 From: Joan M. Grebe (firstname.lastname@example.org) I am puzzled by my ETX -90 Dec lock. When I tighten it, it tightens and then suddenly loosens like something is slipping. The telescope is still functioning but something seems wrong. It is about a year old and did not do this when I first received it. Thanks in advance, Doug GrebeMike here: Do you mean that the locking knob actually rotates when it loosens?
When I am tightening the knob it will start to get snug and then it will become loose again. It is just about tight enough when suddenly it is loose. I try to not tighten it so much that it loosens but it does need to be tight. This is not really all that tight. Just when it starts to snug up using two fingers only and not gripping the knob that tight it will suddenly loosen. Thanks again for helpingMike here: If the lock is not engaging then it is likely that the mechanism is "stripped". You can see article "DEC lock mod" on the Telescope Tech Tips page, which might help. Even better could be the "ETX-90EC DEC fix" article, or perhaps "ETX DEC Lock Not Tightening Fix".
Thanks Mike, It appears that the head of the bolt is turning in the plastic knob, the knob has several cracks in it.Mike here: You might be able to fix that; I believe one of those articles discusses that.
Subject: Re: ETX125 Clicking Sound Sent: Monday, June 28, 2004 13:54:10 From: Douglas Spalding (DSPALDING@kc.rr.com) Amazingly the store (Discovery Store) where I bought the telescope agreed to exchange my telescope for a new one since I have been a good customer. I was well beyond there normal 60 day cutoff for exchanges. I called Meade anyway. They feel that I must have hit a stop and ground the teeth off. I told them that I'm real sure I never hit a hard stop. They then blamed a defective part. Here is some advice they gave me: - Starting position: Turn the OTA counter clockwise all the way to the hard stop. Then go back clockwise about 90 to 180 degrees. They recommended aligning the OTA with the control which on my setup is about 90 degrees. However, on my my setup the OTA is aligned with my North pointing tripod leg at 180 degrees. They said that is OK as a starting position. The telescope always drives clockwise from the start point so they want the telescope to be turned most of the way CCW. I'll just have to be sure I never manually drive it CCW to the hard stop. - I asked what they recommend in terms of storing the telescope. He told me they recommend storing the telescope with the vertical and horizontal locks tightened. It is interesting that they don't ship their telescopes that way. The new one I picked up was not locked in either direction. I'm not sure that any of this is the "right" answer. I just thought I would pass on what I was told. Thanks for your response. It's so nice to know you're there. Doug SpaldingAnd this:
From: Bill VanOrden (email@example.com) Mine did just this when I first got it. I had decided with Meade's terrible QC and equally poor Customer Support that I would purchase mine locally from a dealer. He took the scope apart and found the screws holding the RA drive assembly were very loose. HTH Beevo (aka Bill VanOrden)
Subject: cleaning the optics after dew attacks Sent: Sunday, June 27, 2004 17:30:47 From: David Blackborow (firstname.lastname@example.org) Is it possible to easily clean the optics inside a etx105 after dew attacks? The front lens is easy, a lint free soft cloth, however inside the scope the optics are clearly affected by dust and grime, how do i clean them. Can anyone help? Regerds DaveMike here: To clean inside you would have to remove the corrector lens, which is NOT recommended unless you are willing to take the risk of messing up the optical collimation.
Subject: ETX125 Clicking Sound Sent: Sunday, June 27, 2004 13:13:40 From: Douglas Spalding (DSPALDING@kc.rr.com) My ETX125 just developed a problem with the horizontal drive. After having to exchange my first Meade telescope due to a drive problem, this telescope has worked fine. The last time I used it, it performed flawlessly. I had recalibrated the drives a few days earlier. I then went over 6 weeks with bad weather and travel conflicts. I finally pulled it out last night. While performing the "easy alignment" the horizontal drive began to skip and then quit moving and started making a loud clicking noise. I checked the horizontal lock and it was tight. I then loosened the lock and checked for interference. The telescope turned freely in both directions. It was nowhere near a stop. I tried several more times in both directions, then realized it had to be a problem within the gear drive not with anything I was doing wrong. I've read numerous posts/responses on your web page and it looks like I need to return the telescope to Meade for warranty repair. I'll call them tomorrow. My concern is whether I could have done anything to prevent this since it worked well 6 weeks ago. I stored the telescope in my den so it didn't see any extreme conditions. It was stored with the horizontal lock in the tight position. Is this just a bad component problem or should I be doing something different to take care of the drives? I've only used this telescope about 10 times so it's a real bummer to lose it so early and during a time when my schedule allows me time for astronomy. I would appreciate any insights you have. You helped me earlier with an Autostar issue and I have frequently found answers to other questions on your web page. Thank you for developing and maintaining the web page. The Meade site offers very little technical assistance. Thanks again, Doug SpaldingMike here: While it may or may not be related, I recommend not locking either axis when the telescope is not in use. Let me know what Meade tells you.

Subject: Re: Refurbed ETX 70 CHANCE Sent: Friday, June 25, 2004 18:10:49 From: Ledley (email@example.com) The refurbed ETX70 was delivered Wednesday.It came well packaged and in fine shape.I had a chance to take it out that night.I found that if the directions are followed closely,set up was easy.However,I would recommend that one gets the feel of things in the daylight,at least the first time.Once it was set,I'm happy to report that the targets came into the FOV as advertised...even with the 9mm eyepiece in. I did notice the usual annoyances as reported by others right away.Especially the focus knob.But for $129.00 delivered,it's hard to complain. Greg
Subject: ETX 105 will not slew right Sent: Friday, June 25, 2004 14:44:34 From: Jim Beston (firstname.lastname@example.org) On setting up my ETX tonight I found that it would not slew to the right. A loud clicking noise - indicating a gear slipping could be heard. Slewing to the left or up and down was fine. It was not caused by being against a hard stop. Before I take the base of tomorrow to see what is causing this, I thought I'd ask if you could point me in the right direction. The only thing that I can say that might have caused this problem is that the 'scope was inadvertently subjected to a temperature of around 30C for some hours since the last use. Thanks and Regards JimMike here: High temps are not good but I don't think it necessarily caused this problem. It almost sounds like a wire might be caught. When you open things up, look for a wire near one of the moving parts.
Well Mike, I only wish it had been a trapped wire that was preventing my 105 from slewing right. As the attached photo shows the plastic retaining ring (which I think is open ended)holding the last plastic drive gear in the drive chain has cracked. Under the torque of the turning this allows the smaller gear, indeed the whole gear box to lift away from the large plastic gear at the end of the worm drive causing the drive to momentarily disengage and hence the clicking sound.And more:
I have no idea how this happened since the scope was working perfectly last time I used it. In my opinion a telescope with brilliant design and optics is ruined by cheap, plastic gears. I note from your web site that many people have had trouble with the gear mechanism not just backlash type problems but parts phisically breaking. I would be happy to pay more for decent, metal, gears and thermal overload or mechanical protection of the gearbox and motor. I copy this to Meade, not only for their information, but in the forlorn hope that they might consider revising the ETX gearbox! My ETX is sill under warrenty but, like a lot of other people I don't want to be without it (and we have no Dr Sherod in the U.K!) so I'll have to bear the cost of a new gearbox. Regards Jim
A temporary fix with a nylon cable tie - see photo. Seems to work O.K.
Subject: I need your advice about etx 125 Sent: Wednesday, June 23, 2004 18:15:25 From: Kaan Cindemir (email@example.com) I am writing you from turkey.I hope you can have time to reply my questions.I have been searching for telescope for several months.After visiting your web site i decided to buy Meade 125 etx with uhtc. I also like to take some pictures with it. what should i order for this aim ( i mean most required accessories) and is there a big difference between etx 90 and 125... kind and best regards Kaan CindemirMike here: See the Helpful Information - Astrophotography page as well as the Buyer/New User Tips page and the various Accessory Reviews pages. Which accessories you might want will depend upon how you plan to use the telescope. And yes, there is quite a difference in the views.
Subject: ETX125 Sent: Thursday, June 24, 2004 00:52:44 From: KvnFor9@aol.com (KvnFor9@aol.com) I have just purchased an ETX125 and noticed the build quality of the plastic case is not particularly good i.e. minor chips around screw fittings and the bottom of the case around the lip scratched, etc. in addition there are one or two splashes of what appears to be the purple coating on the plastic. Has anyone seen something like this before, is it normal? The tube itself is free from any obvious defects, however, this does leave one thinking. the ETX125 was brought new and is the new type with UHTC and I checked the mounting arms for the bearing modifications as per one of your site ideas, however, the box it came shows it as a -01. Regards, Kevin FordMike here: Marks in the plastic can be a normal result of it being, well, plastic. Paint shouldn't be there though. Does your dealer assure you it is "new" rather than being a product that was returned by another customer?
Thanks for the reply, unfortunately shop owner's in the UK are well not always that honest so unless I could come up with some concrete evidence I guess I would have no way of telling, may be I am a little to choosey. The main thing is the optics are clean and there is no evidence of wear or play in the unit, the remaining items from the box were sealed and it has a Mead quality tag. You have an excellent web site keep up the good work. Regards Kevin Ford
Subject: ETX-125 Sent: Tuesday, June 22, 2004 23:51:55 From: Mike Lind (LindCochez@Comcast.net) My 125 is 6 months old and has been used maybe 20 times. Lately it has developed a problem tracking East to West (not in polar mount). It makes the normal motor noises as it tracks but every minute or so it clicks and jumps to the west. If you are tracking a planet the planet jumps about one quarter of the way through the field of view in a 26mm eyepiece. Also, there seems to be some slop in my ability to slew right and left. I've trained the drives and still have the problem. Do you have an idea? Have you had this experience? Mike Lind Woodinville, WAMike here: The catching and jumping could be due to a broken gear or a wire catching. if the latter, if the wire gets eventually cut you would have a problem. Or you could be overtightening the axis. But since the telescope is still under warranty, if it is a mechanical problem you should contact Meade.
I do crank down on the AZ axis quite a bit. I'll try less and see what difference it makes. I can't understand why that would make a difference however. Thanks for your response. Oh, and I read on your site about adjusting the Az and Dec percent. I tried that but did not make a thorough evaluation yet.Mike here: It is a friction lock so the more torque required to overcome the friction the less smooth the movement might be.
Subject: Outletting ETX-125? Sent: Tuesday, June 22, 2004 23:43:41 From: anselmo (firstname.lastname@example.org) First of all, congratulations on your SUPERB web on the Meade ETX 125. It is really THE page! My question is: Do you know why Meade is selling its ETX series in some countries at the same prize than in the US (So I guess they loose money in VAT, importing fees, etc), but ONLY this series? I'd like to buy an ETX but I am afraid they're selling here outdated models or, much worse, (slightly) fawlty ones, or at least items rejected in their US Quality Controls? Regards, Anselmo Perez SerradaMike here: International pricing is subject to many variables. Pricing is probably set by Meade International.
Subject: DSX vs ETX Sent: Tuesday, June 22, 2004 17:05:41 From: Wells (Wells@WanderingWells.com) We are just starting with telescopes and trying to decipher all of the modelsthe Meade seems to be the best, but we cannot find any information that really explains the difference between the ETX-90-AT and the DSX-90-AT? Can you help? BTW Love your Websitean amazing amount of information! Many thanks, Linda and Chester WellsMike here: As you can see from the photos linked from the top of the ETX-90 feedback page, the DSX model is on a different mount than the ETX model. The tripod is fixed in Alt/Az mode for the DSX whereas the tripod with the ETX is adjustable and works in Alt/Az and Polar mounting. There is also the single vs dual fork mount. The DSX finderscope is likely more usable when pointed at the zenith than the ETX one due to the angled arm on the DSX. Also, there is the difference in the tube color. But other than these, I am not aware of any other differences.
Great info, Mike. Many thanks for responding. I don't find anything about the DSX having the UHTC coating (which I understand is a significant advantage. Many thanks again! LindaMike here: I would not expect to see UHTC on the DSX line. And UHTC is a good option to consider.
Many thanks, Mike! I bought the ETX-90-AT with UHTC and am looking forward to setting it up. I appreciate all of your help!
Subject: Using Solar Filter with UHTC Sent: Tuesday, June 22, 2004 11:25:25 From: Andrew McKelvy (email@example.com) I've heard that exposing the UHTC coatings of your scope to sunlight for extended periods of time will fade them and eventually destroy them, but would the use of a solar filter prevent that damage or would it still occur? What other things must I take into consideration before using a solar filter on a scope with UHTC? how would heat affect the scope and its different parts?Mike here: I haven't heard that properly "filtered" solar energy will damage the coatings but with focused UNFILTERED solar, light many things can be damaged, including the optics, plastics, glue, your eye, camera, etc.
Subject: ETX70 AT Sent: Tuesday, June 22, 2004 00:01:52 From: Wouden, Jeroen van (Jeroen.van.Wouden@plannederland.nl) I Bought a ETX70 AT, Yesterday I could finally see some stars, en a bit of the moon. I packed out my ETX 70 and till my suprise. I saw that on the front of the OTA a little scratch, not that bad, it does not have any consequences when I took a vieuw at the moon. But what should I do, should I bring the ETX back? I'm a little bit uncertain. Thanx in advance, Jeroen van Wouden Amsterdam, The Netherlands, Sorry for my bad English, I'm not that goodMike here: If you are certain that you didn't scratch it, then yes, I would return it to the dealer. Do you know if it was on display where others could have scratched it? Or perhaps it was one that was returned by another owner.
I'm not certain that I didn't scratch it, but at least I can try to get another ETX I just got it for 3 days. It is at least not that bad as the guy that bought a brand new LX200GPS that was written on your site.
Subject: AutoStar Problem Sent: Monday, June 21, 2004 21:20:47 From: Morgan Wolfe (firstname.lastname@example.org) I have recently purchased and installed the Meade #1244 Electric Focuser I installed it using a combination of the directions included from Meade as well as the Electric Focuser Installations from the Warnings! Section of your website. I encountered two minor setbacks. First: I was left with an extra piece (photo attached) that was not included in any manuals/editorials/reviews/etc
Second: The directions that came with the #1244 kit claim that I can integrate my electric focuser with my Meade AutoStar #497 controller. According to the directions from Meade, I should push the MODE button for 2 seconds and then scroll down in order to find a FOCUS sub-menu. The FOCUS menu/setup was not to be found. I went ahead and upgraded the firmware aboard the AutoStar controller to the latest software from Meade (v. 31 I believe) still no focus option anywhere! I must be making a simple mistake (I hope) or else something is seriously out of whack. Any help would be much appreciated! Thanks, Morgan PS My electric focuser work great with the provided controller but that runs on a 9v battery and I wish for everything to be integrated into one controller i.e.: AutoStar or from a PC with the AutoStar Suite. However, I am very concerned about this extra piece I received in the #1244 kit it was not listed in the package manifest, but I want to know for sure I did not leave anything out.Mike here: That piece doesn't look at all familiar. Since the focuser works fine without it we'll presume all is OK. As to the Autostar not recognizing it, you have plugged it into the AUX port, correct? When the ETX is powered up with the focuser plugged in, it should be recognized by the Autostar and the focus control visible by pressing the MODE key 2-3 seconds and then releasing it.
Hmmmm.... I plugged the focuser into the same port (on the AutoStar hand controller, not the computer) that I plug into in order to update the firmware aboard the AutoStar controller. So, if I plug the focuser into the computer port that says AUX next to where the HBX jack is, I'll be good to go? Thanks Mr. Weasner! Morgan WolfeMike here: Yep, goes into the AUX port on the telescope base, not the Autostar RS-232 port.

Subject: [none] Sent: Monday, June 21, 2004 15:25:50 From: Philip (firstname.lastname@example.org) We recently purchased a Meade etx-90ec with Autostar. We are novices. We did lock the vertical and horizontal and pointed it towards the North Star 1st. We then instructed it to focus on Jupiter and the moon. We are having 2 problems. 1. Each time when autostar finishes moving the telescope, neither viewfinder is focused on the target. We end up having to switch to manual to move it up to the target. 2. When we then manually focused on Jupiter at 1st what we saw was a large golden ellipse with a dark ellipse in the bottom section. We thought we were seeing the dark spot on Jupiter. However, when we then manually focused on the moon (since again the autofocus was not on target) we saw the same thing as we saw when we focused on Jupiter-a large golden ellipse with a dark ellipse in the bottom section. Any idea what are the solutions to these problems?Mike here: First off, as indicated on my ETX Site Home Page, please read the Email Etiquette item.

Subject: Supercharged by Dr. Clay Sent: Monday, June 21, 2004 14:47:11 From: Jack Fox (email@example.com) Dr. Clay: We had clear skies at last, last night and I was able to test the 125 for a couple of hours. I wrote you last week about a drifting problem after the GOTO stopped and then centering the object with the keypad. I am glad to say that the drifting no longer happens. I calibrated the motors before alignment as you suggested and perhaps this cleared it up. As for your Supercharge Service, the scopes optics are now very sharp and clear, the image shifting while focusing is almost non-existent, the motors are smooth and quiet, the keypads are responsive to manually slewing in all directions at low speeds and the GOTO's are accurate (within the field of view using a 26mm eyepiece). I expect the accuracy to improve as I take more time with the alignment process. All in all, I am very pleased with the scopes performance and will let the members of Mike's site and the EXTASTRO newsgroup know of my satisfaction with your service. Highly recommended if your scope is not perfect out of the box. Best regards. Jack Fox

Subject: Alignment of Meade mod 97E...Similart to ETX series? Sent: Saturday, June 19, 2004 23:00:33 From: Dale Harder (email@example.com) I am not a newbie to astronomy or telescopes, but I recently aquired a Meade model 97E spotting scope and I have notice that it is somewhat out of alignment, giving oblong images of stars or planets. Not severe, but enough. The manual does not cover any info on alignment as is custom with my SCT's . I was told that even tho it is not manufactured any longer (Made in 86) that the accessories for the ETX series will fit it. Are there any alignment techniques for the ETX? I have included a picture of the scope.Mike here: If truly the same design as the ETX then the collimation articles on the Telescope Tech Tips page should help. If not, then you might have to just disassemble it and dig in.
There are 3 allen head cap screws countersunk at 120 deg points on the rear cell, but I do not believe they engage the mirror cell internally. I have found no information regarding this scope on the web either. It is a predecessor to the ETX series and a true catidioptic desgn. 90mm corrector, 1000 mm f/11 system. The outer barrel of the scope is turned on a helical thread to adjust focus. I spent a great deal of time on your site, but did not find any relavant info. If you can't help, perhaps you could recomend someone who can. By the way, I am fully capable of handling, cleaning , maintaimg or manufacturing optics in my lab. Thanks, Dale harder.
Subject: Re: Questions on Telescopes Sent: Saturday, June 19, 2004 19:58:09 From: RMDKANE@aol.com (RMDKANE@aol.com) I was wondering if you had an opinion or facts about which telescope brand is the best i.e. Meade, Tasco, Celestron etc. What do you think? Robert.Mike here: Tasco is out of business. Celestron and Meade both have positives and negatives. I have Meade telescopes.
Well, I have felt that from researching online about scope I find that Meade and Celestron seem to be the best scopes out there. I do have a scope in mind, I think I have told you about it. The Meade Telestar DS-2130AT or ATS seems to be a good bargain for $300.00 I was wondering if you would look at it and tell me if you think it would be worth buying. Now the strange thing is that Walmart sells them and I think thats kinda odd. There is a place online that sells them REFURBISHED for slightly cheaper. I am pretty sure I won't be buying it from the online store. I would like to have a BRAND NEW one. See I have a gut feeling that the DS-2130 model might be cheap because its predicessor the DS-2114 is two tone in color and looks better built. The DS-2130 is solid black. Could you tell me if I am crazy and its worth it or if its a waste? Thanks Mike RobertMike here: The DS line is a good line of low-end telescopes. They are definitely better than "Department Store" telescopes although Meade does sell some models through department stores. Just keep two things in mind: 1. Don't let your expectations exceed the telescope's capabilities and 2. the best telescope for you is the one that gets used rather than sitting in the closet.
I was browsing your web page and its photos and some of those photos were unbelieveable!! I noticed that most people used the Meade ETX90. Is that a pretty good scope? I have seen them for about $350. I noticed that alot of those pictures take alot of work to make the objects come out. Can you see alot of those objects people put pictures on your website with just the scope? I mean will they have that much color and detail in just the scope? Say I just bought the ETX90 and all it came with was the basic scope and lenses, will i see those things? ThanksMike here: Brighter objects (Moon, Sun, brighter planets) will show lots of details. Fainter objects will show less details and way less color than you see in photographs. It isn't the telescope that is at fault but the design of the eye; it just isn't good on faint objects. Of course, the larger the telescope aperture the brighter the objects will appear. And yes, the ETX-90 is a fine telescope.
So with your expertise which scope would you prefer, the ETX90 or the DS2130AT? I hope you don't mind all the questions, just don't want to make a wrong decision. RobMike here: I have no experience with the DS models. But I do like my ETX-90.
Mike, What do you think of the Meade ETX70AT?Mike here: See my comments linked at the top of the current "ETX-60, ETX-70" Feedback page.
I think you might have steered me to a different scope to research. Your experiance with the ETX70 kind of delighted me. Gotta go. I will email you again if i have more questions. Thanks

Subject: ETX105 - Transit of Venus. Solarfinder. Sent: Thursday, June 17, 2004 23:32:14 From: Chris Fry (C.Fry@BTinternet.com) Just thought I would relay my experiences last week witnessing the Venus transit from south of england. Arose early and quickly unpacked my trusty ETX105. To my delight I found I could simply desk mount the scope in my study, and with a Baader film filter attached was in good time to witness Venus "1st contact" and watched until it was wholly inside the disk of the Sun. I was only using the standard 26mm eyepiece and this was perfectly acceptable. Packing up the scope, I then dashed off to work and set it up in the office for all my work collegues to participate in the event. They were asking lots of questions about Venus, orbits etc. and were also very interested in the telescope itself - one even asking for 1st refusal if I ever wanted to sell. The event gave ne the excuse to purchase a BC&F Astro Solar Finder which conveniently fits over the front of the ETX finder. It has a short Gnomon standing proud of a white face. With a minimum of fiddling to aling the gnomon properly I found I could use this to re-locate the Sun within about 15-30 seconds whenever we wanted to check progress throughout the morning. Personally I think they could have made the Gnomon longer for more accurate alignment - perhaps I should make my own!! Anyway thanks for maintaining a brilliant site. Chris Fry

Looking at Ebay for accessories I saw these items; 8 D cell external battery pack http://www.weasner.com/etx/menu.html 5 Lens kit http://tinyurl.com/2xxqv Are these worth the money? Thanks. Warm Regards, LouMike here: Can't say about the power pack (since the URL is for my ETX Site) but the eyepiece kit is one that Celestron was offering with new telescopes (similar to the deal that Meade was running last year). They should be fine on your ETX-90.
Sorry about that. I can no longer find it. It was an 8 D battery holder with a connection for the ETX scopes. His premise was that the user would no longer need to take the scope off the tripod to change batteries. It seems a reasonable accessory to me, even without using the scope yet. Actually I did, early this morning looking at the moon. I still have not set up the AutoStar so I just manually moved the scope into position. The view sure beat any binoculars that I have been using for years. <LOL> Any tips on setting up the AutoStar? My knowledge of the stars is rudimentary. I do follow astronomy news but never got to learning much more about the sky than locating Orion and the Big Dipper with Polaris. Another accessory that I see is TELESCOPE FLEXIBLE FOCUSER EXTENDER MEADE ETX MODELS http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=29954&item=3821646848&rd=1 Thanks for your help. Warm Regards, LouMike here: For info on using the Autostar, see the Autostar Info page; lots of info there. As to focuser aids, see the Accessory Reviews - Miscellaneous page for some commercial ones (including flexible cables) and the Telescope Tech Tips page if you want to make your own.
Hi again, After searching via Google I found this site about the battery packs. http://www.atozastro.com/shop/scripts/prodView.asp?idproduct=19 What do you think?Mike here: Should work OK.
Subject: etx 105ec finder scope Sent: Monday, June 14, 2004 13:28:21 From: thebostons (email@example.com) I've read everything I can find about replacing the factory supplied finder scope that came with my ETX 105EC with a finder scope that is more user friendly. I'd like to locate a finder scope I can mount onto my 105 that, once adjusted properly, will maintain the accurate allignment with the OTA when it's stowed in the Meade hard carrying case. Is there ONE finder scope that you or any reader of your site would recommend over all others? This has really become a frustration for me and I'd give anything to get it resolved. ThanksMike here: All commercially available finderscopes with mounting brackets need aligning once in awhile. If you add side pressure from a case, then aligning is even more likely. The only way around this is to permanently mount a finderscope WITH THE RIGHT ALIGNMENT BEFORE PERMANENTLY ATTACHING. If you were to mess up this alignment then you'd be stuck with a poor alignment. Always something to be traded off...
Subject: Quality Issues with New Meade ETX-125 Sent: Monday, June 14, 2004 06:26:03 From: Allen Samuel (firstname.lastname@example.org) I recently purchased (3 months ago) a Meade ETX-125 with UHTC, confident I was buying a quality instrument after doing alot of research and reading the commentary on your outstanding and informative website. The reason I am writing are the serious quality issues I have had with this telescope. The second time I turned on the telescope (out of its box), the electronics would not come on; no red power on light, Autostar would not energize. I immediately called the (photo) shop where I purchased it and received a replacement. I tested it extensively (indoors) learning the setup procedures of the Autostar and was very impressed. I had also purchased an external battery source. As the weather in the Northeast hasn't been great, this weekend was the first opportunity to take the scope to a local astronomy club star party. On starting the setup (initialize) procedure, I heard a loud grinding noise and the horizontal axis stopped turning. The scope had been properly set up in home position and certainly was not up against a rotational stop. I attempted to move the axis' manually from Autostar, the elevation axis was fine, but the horizontal just made its grinding noise; I immediately assumed the gears were stripped. I turned the scope off and then on and the electronics failed--Autostar wouldn't energize (although this time, the red LED power light is on). I checked both external and internal batteries after getting home, and both were fully charged. I am clearly very disappointed with the quality of this instrument, actually quite shocked this could happen to something so new. I am very careful, an engineer, and respectful of how an instrument is to be treated. I haven't yet contacted Meade wanting to know your comments, any quality history you might be aware of, and your thoughts as how to proceed. Thank you, ALLEN SAMUELMike here: Sorry to hear about your experiences. Without knowing what went wrong (but it does sound like a wire got caught and cut) it is difficult to say whether it is a quality issue or whether something shifted/broke during shipment/movement. You could look inside the base and see if you can determine that. But you should let either your dealer or Meade handle it under warranty. Not everyone has issues with their telescopes but it is always possible that something can go wrong.
Thanks for your quick response; I appreciate it. AL SAMUEL
Subject: RE: Transit of Venus - Solar Projection concern Sent: Monday, June 14, 2004 05:32:06 From: Raymond Barbour (ZA) (Raymond.Barbour@za.didata.com) I was using my Celestron 3.4" f5.6 mirror lens for my Pentax camera with a 25mm eyepiece to project the sun's image onto a piece of paper. I think it has a similar design to the ETX ota. I got distracted when I had the eyepiece out the as it was only on a camera tripod the Earth turned and the Sun was focused onto the internal plastic baffle and it started to smoke. From then on I made sure that the Sunlight was coming through the eyepiece by looking at the eyepiece (not through it) as the centre of the eyepiece glass was light with a dark area around it. With the light coming straight through I had no other problems that I've noticed and I had it focus for 10-15 minute stretches. We had a great view of the whole transit for here in Johannesburg, South Africa. Regards Raymond Barbour

Subject: RE: So far, not so good... Sent: Sunday, June 13, 2004 21:19:39 From: Ted Semon (firstname.lastname@example.org) A belated "Thank You" for your detailed reply and my apology for not answering your questions sooner. I received my (repaired) drive via UPS yesterday. And this time, I was much more cautious in how I set things up. To answer your questions, I did everything you mentioned except Calibrating my drives. This must have been the problem (or else perhaps I had a faulty unit) because now the telescope seems to work just fine. My first try at "Easy Align" failed - I couldn't see anything. I more carefully repositioned the Home position and tried the "Easy Align" again. This time it worked fine. I was able to align on Vega and then Antares (easy enough for me to see even with my crappy eyes). Once I had done that, the control unit was able to find Jupiter for me with no problems - pretty neat being able to see 3 of the moons... So, now I'm already unhappy with the magnification :) I've got some things to learn about that (and lots of other stuff, too). I'll be visiting your web site often, I'm sure. I just submitted a $50 pledge also in thanks for your help and in anticipation of future use of your site. Thank you Mike - your help is most appreciated. Ted Semon
Subject: Picking up new ETX-105 next Sunday from Scope City, SF Sent: Sunday, June 13, 2004 16:05:11 From: James Eagle (email@example.com) Thx. for the great site! I was trying to decide between the 90 and 105, and after reading the reports of other users, decided on the 105. I pick it up from Scope City in San Francisco next Sunday. My question is: Are there any things I should check in the store (besides everything being present and not obviously broken) to reduce the likelihood of my having to return the scope later? Thanks. JimMike here: You can check the cleanliness of the optics by removing the covers and just looking at their surfaces. If you are getting an AC Adapter (or want to bring batteries) you can check that the electrics and electronics work. And, as you noted, check that everything is there (26mm eyepiece, manuals, tripod, Autostar #497 and its cable). Beyond that there really isn't much you can do while in the store. But if you are getting it from a reputable dealer you should be OK.
Subject: via iChat Date: Sunday, June 13, 2004 From: firstname.lastname@example.org I've been trying to get my ETX 90 connected to my powerbook G4 for months via a Keyspan Serial-USB USA-18X with no luck. I finally broke down and got a USA-28X. It works great. I don't get it, same driver and I'd assume the 18X is just a single version of the 28X. Anyway, I'm up and running and looking forward to using Scopedriver and Astroplanner tonight. Thanks for the great website.
Subject: Meade case for the ETX 125 Sent: Sunday, June 13, 2004 06:36:04 From: Duane Galensky (email@example.com) I bought the Meade case for the ETX 125. Upon its first use the handle gave out, and I nearly dropped the entire affair smack onto the asphalt. The handle is held in place by two pins, and one of them came clean out. Luckily I located the pin and was able to epoxy it back in place. I smeared a little epoxy on the other side as well, hoping against hope it won't behave similarly. It seems to be sturdy enough now, but I plan on taking extra caution when carrying the instrument. Duane Galensky Member, Amateur Astronomers Association of PittsburghMike here: Glad there was no damage. Although it would have been interesting to hear the report of how well the case performed during a "drop test" of the ETX-125.

What does the ETX stand for? I also have your book, thanks again. I read the reviews for SEARS case No 706.590270, SST, and went out and bought one on sale for $39.95. I left it outside before I set it up for the ETX 125. Today, when I went to start putting foam baffle's in it, I found it had LOTS of water in it. The bottom and both red trays had water. Be careful, it is NOT WATER TIGHT....it leaks. BOB FETTERMAN Wilmington NC Cape Fear Astronomical SocietyMike here: Officially, "ETX" doesn't stand for anything; it is just a name. Unofficially, there are many possibilities and probabilities. "Everyone's Telescope" is the most-often cited one. Good point about non-watertightness. That applies to many cases not specifically designed to be water (or air) tight.

Subject: RE: Transit of Venus - Solar Projection concern Sent: Wednesday, June 9, 2004 -----Original Message----- From: Mike Weasner [mailto:firstname.lastname@example.org] Did you damage your ETX or eyepieces? Solar Projection with the ETX line is NOT recommended due to the high probability of damaging something from the heat buildup inside the OTA. From: Culpan, Gary Oh hell I didn't know that. I only pointed at the Sun for about 2 minutes max and it was partly cloudy. I used the scope last night and split Epsilon Lyra at x297 magnification so hopefully it's fine. Thanks for the info. And: From: Dirk Bauwens (email@example.com) Many thanks for your very kind interest! There was no damage. I was aware of that danger and I had removed the plastic cover for the rear projection as a preventive measure. This seemed to work well with my ETX-90. Also, observing was not continuous (at most 15 minute-periods) and in between, I covered the telescope with a white bedsheet. Thanks again! Dirk Bauwens

Subject: Cody's RA Problem Sent: Monday, June 7, 2004 07:57:46 From: Don Sutherland (email@example.com) Cody was having a problem with the azimuth drive on his ETX-90. From the description, it sounds like a wire is catching in the gears of the azimuth drive and is acting like a ratcheting mechanism. This would explain why the scope moves freely with the lock off and slews only in one direction. This is something he could fix easily by moving the offending wire away from the gears.

Subject: ETX 90, LPI imager and sun filter. Sent: Saturday, June 5, 2004 13:31:33 From: Richard Plowman (firstname.lastname@example.org) As the font of all knowledge on ETX matters can you help please with some advice. The excitement of the transit of Venus is building and for once the weather in the UK looks good. Unfortunately I do not pocess a solar filter and stocks are all out. I do have a good quality sunglass filter for a 0.925 inch eyepiece which can attach to theinner thread on the LPI imager. I tried the systemwith a small 50mm refractor on the sun and it took some reasonable images with the LPI but tracking was difficult to get a good sharp image. The LPI seems fine as the light transmissionthrough the filter is a lot less than normal daylight. I would like to use the system on the ETX 90 and the LPI imager but is there are risk with heat build up and is there any risk to the telescopelens or mirrors or the LPI? Would a short use of say ten minutes be OK? Many thanks Richard Plowman Chichester UKMike here: Solar Filters that attach to an eyepiece should NEVER be used. Only filters from a reputable source that cover the telescope's aperture are safe to use, especially with the ETX models. Otherwise, damage to the telescope (and eye and LPI) can and likely will occur. Solar projection (projecting the image of the sun onto a piece of white cardboard or similar surface) can be done with some telescopes (such as some Newtonian reflectors) as long as there are no plastic or heat sensitive glue or other materials used in the telescope.
Many thanks Mike just as I suspected. I will try and see if an aperature sun filter is available anywhere in the UK. The small 50mm refractor works well with sun projection using a right angle prism erector to reflect the sun upwards. I have never used the glass sun filter for direct observation of the sun for the very reasons you suggest..

I have owned my ETX-125 for about a year now and couldn't be happier with it. I recently purchased the meade #541 power adaptor. Should I leave the batteries in or remove them when using the #541. I only use the scope about once a month, so i'd prefer to remove them in case of an unexpected long storage time. If I remove them, will I have to re-train the drives each time I use the scope? Thank You, TimMike here: You can leave the batteries in however I'd suggest removing them since you hardly use them. That way you won't have to worry about leakage.

Dr. Clay: "You should be able to find a suitable screw at Lowes or Home Depot in the hardware area....it is a #4 machine screw and you can get various head versions of it, but not likely a perfect match." Yes, a #4 machine screw does the trick. I screwed about 4 nuts onto it, all the way up against the head, and it makes for a decent replacement. Meade also sent me a replacement free of charge. They chalked it up to missing original equipment. Now I have a couple of spares in addition to having the original part that I miraculously found. It is now tethered to the telescope with some red string. It's not pretty, but I think it will be effective. I would be curious to hear from you and others on additional ways of preventing the dreaded eyepiece-screw-drop-in-the-grass in the middle of a beautiful night of observing. Thanks for all the help! -KathyAnd:

I place a small carpet on the concrete (to avoid damage to dropped eyepieces and dampen out tripod vibrations. It would probably also make things easier if I dropped a small screw...
It also would be much easier in the long run if these screws were magnetic.....scanning the ground for dropped metal via magnetism is an excellent way to retrieve tiny lost parts....but alas, these are stainless! Dr. Clay
Subject: Urgent DEC problems Sent: Friday, June 4, 2004 08:53:07 From: Michael Morris (email@example.com) HELP! My ETX 90EC refuses to slew in DEC! I can hear the motors turning but the tube doesn't move. The DEC axis is now relatively easy to move up and down, even with the clutch tightened. The RA axis all works fine. Here's the background. I have recently got a adaptor to fit a 35mm SLR onto the prime focus of my ETX90EC. Mindful of the all the warnings about using the ETX for prime focus photography for more than a few nights without employing a counterweight system, I have just finished making myself a counterweight consisting of a long bar that screws into the two tripod mounting socket on the base of the OTA (not the base of the mount). The counterweight itself is simply a stack of large washers on a bolt that is attached to the bar in one of a series of holes, depending upon what equipment I have attached to the rear cell of the ETX. I carefully tested the system with both the Dec and RA clutches released to get it balanced. Only when I was sure it was in balance did I test the system with the DEC and RA clutches tightened. Everything appeared to go ok, with the scope easily slewing in RA and DEC. I then repeated this process of testing the system with the clutches loosened off and then tighten once the system was balanced but with a 2x and then 3x teleconverter between the camera and the adaptor. Again it all seemed ok. I now have a counterweight bar with three positions for the weights, one for the camera with a 3x teleconverter, one for the set up with a 2 x teleconverter and one with just the camera. However, I then took the system outside to run off some final test shots for the Transit of Venus on Tuesday. I power the system up and lined it all up with the SUN, then realised that it whilst it was tracking fine in RA the hand controller was having no effect in DEC. I've tried tightening and loosening the DEC clutch and tried it with all the cameras and counterweights removed but it's just the same! I assume that something has probably broken inside. Has anyone got any ideas what? How would I confirm what it is that's broken and does anyone know any fixes for the problem?

It lost motor control for RA, they replaced the RA circuit board and it now works fine. However, a new fault has occured since this board was replaced, it now slews to an objetc well but one in about ten times it will suddenly pan downwards about 30 degrees and stop after hitting the chosen object??? once this happens you have t re-align the whole thing.

Any attempt of motion clockwise was met with a stand still and a clicking sound. motion counterclockwise is fine. So I can't tell what exactly is broken. Any thoughts? CodyMike here: Do you mean there is one position where the slewing stops? Or that you can slew CCW but when reversing, the slewing immediately stops? If the former, could you be hitting a hardstop? If so, that could be expected if you didn't do the proper rotations when setting up in the HOME position. (I'm assuming you are using an Autostar.)
IM sure im not hitting a stop. the mount moves in one direction but when i reverse it fails to move and the motor makes a clicking sound like the gear is skippingMike here: Could you be over-tightening the axis lock? What happens when you unlock the axis and move the telescope SLOWLY by hand in azimuth? Do you still come to some obstruction when rotating CW?
moves fine with lockoff in both directions. With the lock of I tried the motor and it runs perfectly in one direction but does the same click in reverse.Mike here: With the axis unlocked, you still hear the clicking? Not good.
