Subject: ETX Live Forum Sent: Saturday, August 31, 2013 16:48:10 From: Sterling Archer (firstname.lastname@example.org) I hit send button by accident earlier. I just found your site little over a week ago when I bought an ETX90 for under $30.. I was bitten by the astronomy bug recently and haven't really been into it since the 80's.. ( using a friends Edmunds Astoscan and an old 60mm Tasco refractor) I found out a couple days ago that you will not be active on your websites starting Sept 1. .I just wanted to let you know what a great job you have done on your ETX and Cassiopeia site. I also went over the other parts of your site which i thoroughly enjoyed. I like the feel, the simplicity, the pics, and the information of your sites. I look forward reading about any updates or activities that you have going on. I don't have a Facebook or twitter but will get one soon... maybe ( I work in IT and my friends think I'm crazy that I'm not on any social media) Any-hows...I just wanted to say Thank you !!! and ... wish you good luck in your future endeavors. Clear Skies to you... Roger PS . has anyone ever brought up the idea of any fund raising for you and your site? I know it can be tiring administrating a site like this.. but its just a thought.Mike here: Thanks. Supporting of the ETX Site will continue via pledges for those so inclined to contribute. That will help ensure the ETX Site remains online and maybe someday return (assuming my Internet access improves).

Subject: SmartFinder Lens Sent: Saturday, August 31, 2013 02:49:05 From: david maitland (firstname.lastname@example.org) Any Idea where i can find a lens for the red dot finder on LNT module on my etx pe Cheers DavidMike here: Try Telescope Warehouse (link on the Astronomy Links page). There were two styles of SmartFinder/LNT modules used on the PE models; be certain to specify which model you have.
Subject: Finderscope bracket is loose... Sent: Friday, August 30, 2013 20:39:16 From: CaptainDynamite110 . (email@example.com) I had a small question hoping you can help me a bit. On my ETX-125EC, my finderscope bracket screw came loose...I had tried the smallest allenhead wrench I had, but it's useless. Do you if I can get some super tiny allenhead wrenches or can I get away with using a precision phillips head screwdriver? Thanks in advance!Mike here: Some screws on some Meade telescopes are Torx style. You might try a small Torx head driver.
I looked for a Torx precision screwdriver at Home Depot and it worked! It was $6 so wasn't that expensive. Thanks for the help!
Subject: Welcome back Sent: Thursday, August 29, 2013 07:39:43 From: Micki Goodman (firstname.lastname@example.org) Hello Mike. It was good to see another observatory report, although limited. Sorry about your cold, I hope you recover quickly. I am in the process of repairing my ETX 90 right fork arm pivot. I am attempting (from your tech page) the mod to insert the longer threaded insert and a screw, for strength. I hope this will keep the plastic pivot from frequently breaking. All else is working well. May your skies and sinuses be clear. As a side note, I am also a a US Air Force retiree (non-pilot). Be well-FredMike here: Thanks. It was super to be back in the observatory. Clouds have returned. Just not getting much breaks from them this summer. Good luck with the ETX fix. I posted some additional RTA repair info on 27 August.
Hi again Mike. I wasn't going to mention the missing Tech Tips post, but nothing showed up in that section. I'm getting ready to epoxy the brass insert into the pivot post. If all goes well I can get it back together later today.Mike here: Is this the one you are not seeing?
I assumed you were talking about repairing the Right Tube Adapter.
Hello Mike. Still completely cloudy here this evening. I finally reinforced the RTA and I hope that will prevent it from breaking again. I have attached the Tech Page info you emailed me about (RTA repair). Although the subject date is correct, the info (as shown) is from 1999. Are we in a worm hole? Your advice and support is always appreciated, and I hope there will be an internet speed improvement for you, on the horizon. By the way, I used to teach the instrument flying on the T-4 trainer at Randolph AFB from 1968-73. What craft(s) did you fly the most often? Have a great Labor DAy Holiday and recover, from your cold, to enjoy it in time.
Mike here: Whew. You had me worried; I thought maybe I had uploaded the wrong page! But, no, the updated info is there, near the bottom of the page:
Check near the bottom of our Photo Galleries page (http://www.weasner.com/photos/index.html) and you'll see some photos of my time in the T-37, T-38, and A-7D. The Webb AFB photos should bring back memories!
Subject: re: ETX Hardstops Sent: Tuesday, August 27, 2013 16:23:33 From: Andrew Johansen (email@example.com) Gday Mike Just saw this > I did find the hard stop articles > Still I don't understand how the scope rotates 720 > If I machine a new hard stop ring and replace the pins > It's only gonna rotate almost 360 > Besides that I can't figure out what "check mount error" means > I know the scope thinks its gonna run into the stops or wrap the wires Two things a) The Check Mount warning is actually related to the upper and lower slew limits. If the target is outside the upper or lower limits, you get that error. Simply check and reset the limits and the error should go away. b) The hardstop "ring" fits between two pins one in the upper platen and one in the base. With no hardstop ring in place, these pins don't hit each other hence the scope can rotate an unlimited amount. When the ring is fitted and you turn the scope to one way you hit the stops. On reversing direction, after 350deg, the moving pin picks up the tab on the ring and then moves the whole ring through another 350deg until it hits the lower pin on the other side. Thus you get 700 deg of motion. If you make a new ring, you MUST ensure it has some form of shock absorber in it, as otherwise you will shear off the pins very quickly. As the poster has access to a machine shop. One person i heard of made a new "split metal" ring up, a bit like a Circlip ( IIRC he used round spring steel from a spring maker ) it was slightly oversize with long tangs on each end to pick up the pins. On hitting the stops, the design operated like a large circular leaf spring to absorb the shock. Andrew
From: Micky Pellegrin (firstname.lastname@example.org) Andrew Thankxz for your reply Any chance you have a link to the custom made leaf spring style? I'm familiar with leaf spring as I have spring steel for 1/10 scale rc trucks I have one of these http://m.ebay.com/search?kw=Mini+slip+ring&isNewKw=1&pgn=1&epp=24&mfs=SBCLK&acimp=0 &itemId=&cnm=&cid=&sqp=Mini+slip+ring&_trksid=p2056088.m2428.l1313.TR0.TRC0.XMini+slip+ring I use large ones like this in cranes and construction equipment With that said if I add a slip ring(swivel) and delete the hard stops(if possible) Is there a way to trick the etx or set the limits to allow the scope to work?

The limits i mentioned are software based, and are set via the max and min elevations under the Setup > Telescope > menu The hardstops/base position has NOTHING to do with the limits message you are getting. That message is only related to the elevation of the Alt Axis relative to the base. If you reset the limits via the Hbx, you will be able to use the scope without the RA hardstops, however, you do risk cutting the wires going from the base to forkarm. If you cut the 12V line, you risk frying stuff a lot more expensive than the ring. >> I will experiment and put the scope back together >> If I do find something that works( besides the original parts)ill keep you updated. >> >> My upper pin has broke off,no biggie >> Is there a link you know of that shows more detail of the plastic hard stop ring Ref diag 5 in http://www.weasner.com/etx/techtips/2010/Analysis_of_ETX125PE.html Most people end up breaking the tangs off, or the pin slips over one and gets stuck between the tangs, hence reducing the travel to 350deg.

Subject: ETX 90AT vs ETX 90 MAK Sent: Monday, August 26, 2013 05:49:01 From: Khalid Abdulaziz Al Jame (email@example.com) what is difference between ETX 90AT and ETX 90 MAK ? i have read your book (Using the Meade ETX )you did not mention to ETX 90 MAK. Regards Khalid Saudi Arabia Sent from my iPadMike here: "MAK" applied to the ETX name is not an official model designation. MAK refers to the Maksutov-Cassegrain optical design of the ETX-90/105/125 models and applies to EC/AT/PE models as well as the original ETX Astro (now known as the ETX-90RA). It also applies to the current ETX-90 model.
Subject: Etx125 hard stop Sent: Saturday, August 24, 2013 08:45:40 From: Micky Pellegrin (firstname.lastname@example.org) I have a Meade etx125at I believe Bought new in 2005 When aligning I have a check mount error Pulled the lil guy apart and one of the cast pins and the plastic hard stop ring broke Is there a way to bypass something in the computer so the scope doesn't know about the hard stop? I can install an electric swivel so wrapping wires won't be an issues Also I do not understand how the hard stop allows the scope to rotate more than one revolution Ant links to something that shows a hard stop set up I have access to a machine shop to make a new hard stop ring but I'd like to know more about it first How does the etx know to display the check mount error? If it knows where the hard stops are then why will it allow you to set up wrong and run into the hard stop Sent from my iPhoneMike here: There are three articles on "hard stop" on the Helpful Information: Telescope Tech Tips page. You might want to check those. The ETX (nor AutoStar) does not "know" where these are located; that's why you have to manually set up the telescope in the proper HOME position prior to doing an AutoStar alignment. There is a CORD WRAP setting in the AutoStar (although you may have to apply a "patch" to enable it).
I did find the hard stop articles Still I don't understand how the scope rotates 720 If I machine a new hard stop ring and replace the pins It's only gonna rotate almost 360 Besides that I can't figure out what "check mount error" means I know the scope thinks its gonna run into the stops or wrap the wires But again how does the scope know that? If I can bypass what ever causes the check mount error I would be fineMike here: The Check Mount Error occurs whenever the AutoStar detects that it can't move the telescope. That usually means some obstruction is preventing movement. It could be some debris or a wire. Use caution if it is a wire; forcing movement could cut the wire. The hard stop mechanism is designed to allow rotation of almost but not quite 720 degrees.
Subject: Metal Geat Set For ETX 90-RA? Sent: Wednesday, August 21, 2013 14:39:49 From: Shneor Sherman (email@example.com) Hi Mr. Weasner, I've followed your ETX information on and off for 15 years or so. I have an ETX-90 OTA that's been my travel scope for awhile. I recently purchased an ETX 90-RA with Autostar Controller and tripod with ETX mount. I was told that some gears were broken when I purchased it, but when I opened the case, what was inside was not broken; however, in a plastic bag were some greenish plastic gears and a black frame, including a metal worm gear. So perhaps you if there's a kit to replace the plastic gears? If not is there a diagram that would inform me as to how to reassemble the gears in the plastic bag and the frame (there are some long screws as well)? All else seems to work correctly. I am hoping you can point me to a dram and/or instructions on reassembling the gears. Thanks for any help you can give me. Shneor ShermanMike here: Just to clarify, the ETX-90RA is not capable of using the AutoStar. The ETX-90EC/AT/EC models are. There are several gear and gearbox articles on the Helpful Information: Telescope Tech Tips page. Perhaps one of those articles will help you identify the parts.
Then I have the model wrong. the base has "computer Control" written on it: and several inputs, one of which fits the Autostar plug. I turned it on and the autostar told me the telescope was moving. So where can I find the model? All the rest remains true, the person who sold this told me it was an RA but has never used it. Thx, ShneorMike here: If there is a small finderscope tube mounted on the left side of main telescope tube, then it is an ETX-90EC or AT model. If there is a LNT/SmartFinder (red-dot) finder instead, then it is an ETX-90PE (Premier Edition) or it could be the latest ETX-90 model. If you see Auto Align in the Setup: Align menu or Finder options in the MODE menu, then you have the LNT model.
Sorry - I did finada manual on the bottom of the box, it is an EC. There's a small finderscope (8x20, I think) mounted as you describe. I haven't gone beyond the immediate (telescope is turning" message. Thx, Shneor
Subject: Converting etx 60 to etx 70 Sent: Monday, August 19, 2013 14:26:54 From: Larry (firstname.lastname@example.org) I bought an etx70 for parts off craigslist recently. It had been knocked over and the eyepiece adapter was broken off. I hope to be able to repair it. After looking at some of the ext70 instruction pages, I took the objective lens out and put it back in to get a little experience on the technique required. Since the lens cap for the 60 also fits the 70, that got me wondering if the 70 lens will fit into the 60 body. I took some measurements and it looks as though the tubes are the same size. Can I drop the 70 objective assembly into my older 60 without modification? I'm about 99 percent convinced it will work, but I would like to be 100 percent SURE before I tear apart my 60. Has anyone done this? It looks to be pretty simple. Does anyone know where I can find an etx70 eyepiece holder assembly (the black plastic back part of the OTA) or its part number? I've tried looking through the meade site with no luck. I'd like to repair the broken one to give to my grandson. (He's getting the 60mm objective) I bought my 60 off craigslist also. It has a brass eyepiece holder with a brass barrel 9mm. Are these models common? I don't want to destroy it's value if it's an uncommon or collectable model. Thanks for maintaining the site with all it's invaluable information. Great place to visit and learn.Mike here: It might fit but I don't have an ETX-60 to confirm measurements. But I'll post your inquiry on the next ETX Site update. As to brass, that sounds unique.
Subject: ETX -90EC repair? Sent: Monday, August 19, 2013 13:55:06 From: Ned Thanhouser (email@example.com) Hi, I have a ETX-90EC and the vertical declination gear or pulley belt seems to be broken (I.E. no resistance or motor drive in this axis). Mead reports no support. Recommendation? Thanks. Ned Connected by DROID on Verizon WirelessMike here: It sounds like the Right Tube Adapter is broken. You may be able to repair it yourself. See the article "ETX-90EC DEC fix (Right Tube Adapter repair)" on the Helpful Information: Telescope Tech Tips page. Alternatively, you can contact Dr. Clay Sherrod for his Supercharge Tune-Up Service (link on the ETX Site home page).
Thank you so much...I shall endeavor to fix it.
Disassembly reveals the problem as described in the article you referred to below "ETX-90EC DEC fix (Right Tube Adapter repair)." The DEC shaft is sheared off at the edge of the press-nut. See attached images. The fix appears to be to just epoxy these two parts back together...yes? But I am very concerned about getting epoxy where it shouldn't and bugger the whole assembly. I don't need a new bushing as it is still secure, although Tony von Ruden's solution appears more robust with the longer bushing. Can you please confirm? Any where to get a new part? Also, I am looking for a solar filter to image the 2017 total eclipse that will pass through Oregon. And, a T-mount for my Nikon digital D40...any suggestions? Thanks so much for your help!Mike here: Epoxy may work although there is a lot of torque there. You might try Telescope Warehouse (link on the Astronomy Links page) for a replacement RTA but I doubt he has any without purchasing a new mount. As to a filter, see the Accessory Reviews: Filters page. You can get a filter and T-ring for your camera from any reputable telescope dealer, such as OPT.
Thanks for the suggestion, I'll keep you posted. Ned
Subject: Thanks for your ETX book Sent: Sunday, August 18, 2013 21:47:58 From: Aart Bik (firstname.lastname@example.org) Just a note to thank you for your nice book (and website) on using the Meade ETX. I had owned an ETX for quite a while already, but by reading your book recently I got interested in astro-photography using the ETX.

Regards, Sven-Ove AunoMike here: I did not test either Southern Stars SkyFi or GC Wi-Fi Adapter with the ETX-70 with AutoStar #494. However, it should work if an AutoStar #497 were used on the ETX-70 (or ETX-80).
Subject: Your announcement of August 11 Sent: Tuesday, August 13, 2013 13:35:01 From: Krobusek Bruce (firstname.lastname@example.org) I just now saw your announcement that you will be unable to participate on your ETX site as you have been in the past. I certainly understand your predicament, and the reasons you've done what you've done. But it still sucks... :-) Hopefully you'll be able to continue updating your Cassiopeia Observatory reports. I like reading about all of the critters you run into out there. It makes me very grateful I still live in the North East! :-) Thanks for everything you've done for the Meade ETX scopes, and for the hobby in general. Clear skies! Bruce Bruce A.

Subject: Internet Woes Sent: Monday, August 12, 2013 15:32:14 From: Micki Goodman (email@example.com) Hello Mike. I am truly sorry to hear of the internet service problems you encountered. I went through the same situation about 4 years ago. I live in the northern end of a county, bordering Colorado Springs, and the same companies dragged their feet before the complaints were finally heard. We also have limiting old copper. How is your cell phone infrastructure, out in Oracle? Would it be a viable solution, with hotspot, to get some decent internet service? I realize that all the wireless providers put ridiculous caps on their so-called unlimited service. Sprint seems to be, for now, almost truly unlimited. Beyond all that, all we can do, for now, is hope that the President's rural internet plan gets put into place soon. On a more positive note, on the 9th I managed to photograph a few dimmer meteor streaks, and last night I got another (1 out of 3 dozen exposures). As you know, trying to photograph these is like playing the carnival game "Whack-a-mole". I pray that something helpful comes along soon, for your internet service. In the mean time, I will continue to enjoy your observatory reports. To meteor streaks and hopefully just as fast internet service in the near future.-FredMike here: AT&T has 4G service here. But the monthly data restriction is the killer. I had checked with AT&T previously about connecting our computers to it. Unfortunately, the cell service is not set up for multiple computers.
Subject: Meade ETX-70AT Motor Unit Fail message Sent: Monday, August 12, 2013 13:32:25 From: Thomas Chousos (firstname.lastname@example.org) I have an ETX-70AT with the following problem. The autostar shows the message ''motor unit fail'' . Trying to make it work I opened it and found out that the azimuth motor was broken to MANY pieces. I made a call to the distributor who told me that no motors can be found, there is no way to get this fixed by myself and that I should use it without the autostar. OK time to play the doctor, after four hours the motor was fixed with all parts moving properly plus the IR sensor in the right place. BUT once again the same message on the screen. Then I wanted to see if the motors would work with external power and ok they both work. I also spotted that when I switch on the power the IR transmitters are off (checked with NV goggles) , is this a problem or they emit IR light only when the motors are working? Can I reset the unit from the autostar or the pcb board in the scope? What if I connect it to pc and try to work with Cartes Du Ciel? If you have any solution it would be great to read it. Best regards Thomas GreeceMike here: Try a CALIBRATE MOTOR. If battery power is low, that may eliminate the error. If the encoders are bad, try Telescope Warehouse for replacements. (Link on the Astronomy Links page.). If the encoders are bad, computer software won't work either.
Subject: ETX Site Sent: Monday, August 12, 2013 12:29:46 From: John Farrant (email@example.com) Such sad news... Without the information on your site my ETX 125 would never have functioned again (PSU error four years ago!). Your site has become a daily source of ETX news for me and many others. Through your efforts you have engouraged and inspired thousand of people both young and old in this wonderfull hobby. With so many other distractions these days - tablets, phones, games machines etc - the need for dedicated amateurs - for what ever discipline - like yourself, couldn't be greater. Perhaps one day, you'll browse your site and pick out what you consider informative, funny or just plain stupid, requests for help on ETX matters and write another book. Plenty of good material there! Perhaps the price of copper cable will fall - we can only hope. Kindest regards to you and yours. Many thanks, John Farrant

Subject: Possible Autostar problem with tripod using ETX125. Sent: Sunday, August 11, 2013 09:20:21 From: Brian Hollins (email@example.com) After my usual accurate easy alignment, (with Arcturas and Altair), I was able to slew to targets from 'tonights best' with ease. Suddenly this ceased and I could not locate, for example Albireo, which is normally very easy and usually dead centre with my 25mm eyepiece. After some time trying to re-align with no improvement I decided to give up for the night but when I lifted the tripod to take the 'scope indoors I noticed some movement of the mounting head and found that the retaining screw, which holds the hinged platform onto the adjustable vertical bar for latitude setting had come loose and finally fallen out. This was allowing the platform to point up higher than normal and must have been moving around while the scope was slewing until the screw finally fell out. Luckily I found the screw and replaced it with a dab off 'loctite' to hopefully avoid a future recurrence of this problem. I realise now that this would have thrown the 'level' alignment of the tripod completely off and the 'scope would have been widely off target when moving around the sky. I hope this might help others who have an apparent Autostar accuracy problem as it is not something I, personally; would have checked in order to rectify the fault. Brian Hollins, 'Mighty ETX Fan, UK
Subject: EXT90EC Sent: Friday, August 9, 2013 05:20:30 From: Tom S (firstname.lastname@example.org) After being gone for awhile it takes some catching up. Anyway I used my controller on another ETX and it duplicates my problem. i.e. very irratic on the three higher speeds. (won't rotate) Kinda points to the controller, would you say?? TomMike here: Since you didn't say you have the AutoStar, I'll assume you have just the standard EC handcontroller with your ETX-90EC. Since the problem occurs on two ETX telescopes, it does sound like the handcontroller. But you might check the batteries and HBX cable. Look for dirty pins and bent pins on the cable connector and the HBX port on the ETX.
Pins and cable check out OK. Trying to locate a standard EC controller (new or used) but no luck.....any suggestions?Mike here: I'd recommend getting an AutoStar #497. More flexibility. But if you want an old EC handcontroller, try Telescope Warehouse (link on the Astronomy Links page).
Subject: re: troubleshooting new etx-80 slewing to ground Sent: Thursday, August 8, 2013 19:21:57 From: richard seymour (email@example.com) Wow! You have one of the rare handboxes programmed for the Meade 4504 or EQ114/DH telescopes! Those are "GEM" (German Equatorial Mount) models, hence always "Polar". And they do not allow changing the model. I'm sure that there are *many* owners of those (no longer sold) scopes who would love to buy (or trade) your "494" for one of theirs, if they had picked up a "normal" 494 by mistake. 4504 people hang out here: http://groups.yahoo.com/group/Meade4504Telescopes/ Despite your needs, you have what some other people would consider a very lucky find. good luck --dick seymour
Something i forgot to ask/add.... if it has the word "Starfinder" below the display window (instead of Autostar), that ices the cake in terms of identification. good luck --dick

I just bought a new etx-80 but the autostar handbox got thrown away. I bought a used 494 off ebay. When I plug it in it starts up and will slew the telescope but it slews to the ground. I discovered it is set for polar alignment. For some reason there is no mount option under the setup/telescope menu and I cannot choose a telescope type either. Can I attempt a polar alignment using my altitude-azimuth double fork mount? Also I was reading online that the alt/az ratio on the etx models was 1.36889. I was able to change that thinking it was the cure but no luck. I did try a reset with the handbox and don't know what else to try. I can't find a place that sells new 494 handbox controllers or I would try that. Any suggestions would be great. Thank you. JodiMike here: Do a CALIBRATE MOTOR and TRAIN DRIVES from the AutoStar. That may solve the startup slewing. However, if the #494 AutoStar you got pre-dates the ETX-80 release, the ETX-80 will not appear. There is no user installable update for the AutoStar #494. Your best bet would be to get a #497 AutoStar, which is user update-able.
