Subject: Re: Meade illuminated reticle Sent: Monday, May 31, 2010 14:03:10 From: Ludwig Krijgshaftig (email@example.com) This is a rather late follow-up to a short e-mail exchange we had beginning of April. I finally got around to measuring the voltage output of the reticle port on the LX200. When increasing the brightness through the Autostar II it jumps from zero to 1.2V and then in small steps increases to 1.6V. So that is indeed the same as with your wireless model. It could also do with one penlight (AA) battery. Not sure if I want to, but now at least I could decide to make a simple power feed for the reticle to use it on the ETX as well. Although I must say the best use I found so far for the reticle is in when aligning the scope with a finder in daylight and also when training drives. Anyway, since I made the measurement, just wanted to share this with you. Kind regards, Ludwig

Subject: etx 125AT declination and right ascension problems Sent: Sunday, May 30, 2010 11:57:18 From: Craig Fuhs (email@example.com) I have been reading your website with great interest and truly appreciate the devotion you put into maintaining it. I was recently given an ETX 125AT by a fellow, who bought it new, and said that it had never worked and he was going to use it as a boat anchor if I did not want it. Although dirty, appears to have been kept in the garage, the only damage I noted was the RA lever was broken off. I have found a needle nosed pliers does the trick to tighten and loosen it. I initially found that the declination worked with the arrow keys but now no longer does. I replaced the batteries thinking that may have been a problem. I then did a reset and went through the menu and chose calibrate motors and noted that there was no declination movement. Subsequently I tried to train the drive and the left and right worked and I erroneously pressed a wrong button and rather than try to figure it out I did a reset. Repeating the procedure I centered an object and pressed enter, the telescope went up and down briefly and began to continually slew to the right until I turned it off after it travelled in excess of 90 degrees. My questions are: 1) Is this a boat anchor disguised as a telescope? 2) Is there and diagnostic test I can do to identify what is going on? 3) Do you think it is the hand controller? 4) Should I send it in for repair? Dr Clay? 5) Should I find a 10 year old to figure it out for me, my grandson currently programs my cell phone! Should you find available time to respond I would greatly appreciate it. Enjoy the holiday, Craig Fuhs Burnsville, MNMike here: First, if the telescope was dirty, you might want to check the condition of the HBX jacks (both ETX base and on the AutoStar) and the connectors at the ends of the HBX cable. The pins should be clean. Also, check the battery compartment for any corrosion if the telescope was stored with the batteries inserted. I recommend doing the RESET again, followed by a CALIBRATE MOTOR. If that goes OK, then do the TRAIN DRIVES on both axes. If the telescope does not respond in Declination, then the axis lock may be broken or overtightened. If the telescope tube stays put when you place it horizontal and then lock it, the lock is probably OK. Just be certain you don't overtighten it. There are some RA lever articles on the Helpful Information: Telescope Tech Tips page if you want to stop using the pliers.
Subject: Owl Astronomy for reasonably priced accessories Sent: Saturday, May 29, 2010 12:22:42 From: Ross Elkins (firstname.lastname@example.org) On the recommendation of a buddy who is an experienced amateur astronomer, I purchased a lens from these folks. http://www.owlastronomy.com/ I am very pleased with the functioning of a 20mm enhanced wide angle that I just received. It is edge blackened too. It was $38.41 w/shipping. Of course these lens are primarily for viewing deep sky stuff and I just did a quick look of the moon and Saturn last night. I didn't notice any difference in quality to my collection of Meade lenses. They say that they directly buy their products from some of the same oriental manufacturers who are making the most expensive stuff. Fit and finish are the equal of my other lens. They sell out their stock as soon as it arrives so you should expect a 3-4 week wait for anything popular which seems to be all the lens I have ordered!! They also have many many special very affordable deals on lots of lens they buy off the (grey markets?). http://www.owlastronomy.com/exwide.htm I just ordered what they call a 11 MM Ultra-Wide Angle - 1.25 inch for $41+$5 S&H http://www.owlastronomy.com/ultrawide.htm Ross
Subject: ETX 125 EC Gears Sent: Saturday, May 22, 2010 01:14:30 From: Steve (email@example.com) Hi, just brought a 2nd hand ETX 125 EC scope and looks in A1 condition. When i tighten the righthand knob on the side of the scope it holds the tube firmly in place but i can still move it a few mm is that normal and will it affect its performance? Many thanks SteveMike here: Some movement is normal. The locks are friction style, so you can push on the tube and move it. Since it is not a normal operation to push on the tube by hand, performance should not be affected when using the handcontroller.
Mike, thanks very much for your help, Steve
Subject: Viewing the moon, questions about going to 8" scope Sent: Friday, May 21, 2010 10:56:42 From: Ross Elkins (firstname.lastname@example.org) Boy, I can't believe how cool it is watching the Moon for the first time thru all the phases. I noticed last night that I could clearly see the shadows of the crater walls on the floor of some craters I looked at. I was able to use my 9.4 lens with the barlow and got really close. I imagined myself standing there on the crater floor as I could form a picture of what the surrounding rocky crags looked like. Why, it was a scene off a cover of a 1950's sci-fi book by Asimov! Question, will an 8" scope be a spectacular upgrade over my etx 125, especially for deep sky views (well actually for all viewing!) Would one of the older Meade SCT's fit the bill or should I save my $$ for a newer one with the computer control as maybe they have better optics too. Tia, Ross BTW Here I am as my friends commented, looking very rossish!
Subject: RE: Improving Image on an ETX70 Sent: Friday, May 21, 2010 05:38:22 From: Travis Whitlow (email@example.com) Of course, as soon as I said I'd go out and look at the sky the clouds rolled in and Tuesday night's outing was cancelled. But I did get a look at the sky Wednesday night through a sky pretty much covered by high thin-to-thick clouds and verified what I told you. Using a Meade 32mm plossel, a Criterion 12mm Ramsden and a Vixen 8mm LVW, Venus was totally unrecognizable. The planet itself was a bright blob that could not be brought to focus. It appeared to have an edge-on ring, like Saturn (but much wider), with abut six or eight spikes emanating radially from the center. I got a similar effect with Saturn. However, I was using the Vixen for the first time (it's a 17 oz. eyepiece, so not really suited to a small scope like this) and actually got the disk to come to focus. But the radial spikes remained, though there were fewer of them. The moon, by the way, looked excellent and focused beautifully, though showing the color fringing characteristic of this little scope. And, as usual, stars and deep sky looked fine. So this is the mystery. I can't imagine why the stars, moon and deep sky look fine while the planets are such a disaster. I've never seen a reference to this kind of behavior with any scope, so for now I'm just going to blame it on astigmatism or coma. Thanks again for your help. TravisMike here: You mention seeing "spikes" in the brighter small images, like the planets. I'm beginning to wonder if someone tried to clean the objective or the flip-mirror and did some damage or just did a poor job. Cleaning the flip-mirror is not recommended as it is a first-surface mirror and highly susceptible to be damaged.
Well, as I mentioned, I've had three different objectives in this scope and replaced the flip mirror because I thought the source of the problem must have been one of those two things. But it wasn't. But as I said, I'm ready to give up and just appreciate this scope for what it does well: wide views of everything but planets. Thanks again for your help. TravisMike here: It is strange that when you focus on the moon, that planets appear so bad even though you don't change the focus from where it was when you viewed the moon. Of course, the ETX-70 is a short focal length refractor and so you can't get much magnification. And keep in mind the theoretical maximum magnification of the small aperture telescope (see the FAQ page if you are unsure what that is).

Subject: Meade ETX 105PE - Blur Image Sent: Wednesday, May 19, 2010 07:31:33 From: deb kapil (email@example.com) i bought a meade etx 105pe, i am very new to the telescope world. the telescope looks fine and no damage, i am trying to see object that are about 20 to 30 feet distance. the object looks very blurred hard to figure out what i am looking at when seen through the eye piece. when i take out the eye piece the object looks fine through the flip mirror , i think the object from eye piece to flip mirror become blurred and the object is hardly visible. i am using a 26mm eye piece.is there anything i have to adjust? please advise. regards kapil debMike here: There is a minimum focusing distance (about 15 feet). How do objects further away look? Say something about a mile away? Or even the moon, which is visible in the evening now?
thanks for replying, it looks the samea mile away or distant more than that. i thought atleast it should be visible like a binocular but everything is very blur, the lens is working because when i move the telescope around i could make out it is moving from dark object to some light object during night time,when i take off the eye piece, i could see the image in the flip mirror and could bring the object closer by adjusting the zoom. is my eye piece is not working or their is some kind of adjustment? please advise. regards kapilMike here: With the telescope pointed at a distant object (a building or the Moon), when you rotate the focus knob, does the image "blur" in the eyepiece change?
no, it does not blur,the image is so much blur that it is very hard to recognize what i am looking at.but everything looks fine if i take out the eye piece, i could see the image on the flip miror, when i turn the knob i could make out clearly the image is zooming in without any blur, but this does not happen when i use the 26mm eye piece the image is completly blurred/distorted.Mike here: Lets clarify some points. First, the image you see without the eyepiece in place is not a good indicator of focus when using your eye. You need to use the eyepiece. Second, rotating the focus knob is not a "zoom" to change the magnification. I suggest pointing the telescope at the moon tonight and with the 26mm eyepiece inserted into the eyepiece hole, rotate the focus knob. The clarity of the image seen in the eyepiece should change. It may get worse or better, depending on which way you rotate the knob.
Subject: Meade SmartFinder Red Dot Timeout Question Sent: Sunday, May 16, 2010 17:05:04 From: Milton Demaray (MILTONDEMARAY@COMCAST.NET) I have a DS 2130ATS-LNT. I'm a relatively new astronomical observer, and still trying to get accustomed to the features of this telescope. I find it particularly frustrating to find that the StarFinder red dot has timed out, just when I need it. There doesn't appear to be any way to control/disable the timeout feature. Of course I can go through the set procedure again, but this disrupts easy-alignment operations, and at the very least takes some time while Earth continues to rotate. I notice that there is some kind of connector jack on the side of the StarFinder. It seems likely that this is for an external power. Can you supply, or tell how to find technical information relating to this jack. Is it for external power? If so, what polarity and voltage? Thanks for any information. Milton DemarayMike here: The jack on the LNT module is for an atomic clock module, not power. However, as mentioned further down this Feedback page, you can use the "0" key on an AutoStar #497 to turn the red-dot on and off.
Thanks for the quick response. Unfortunately, I don't have AutoStar Handbox #497. Mine is #494, having no numeric buttons. I guess I'm out of luck. Best Regards, Milton Demaray
Subject: RE: Improving Image on an ETX70 Sent: Sunday, May 16, 2010 14:10:08 From: Travis Whitlow (firstname.lastname@example.org) I can focus on a star and/or deep sky object and the image looks sharp. I then move to a planet or the moon and the image becomes seriously elongated and soft. The shortest eyepiece I use with this scope is about 15mm so the images are never all that big. But, for example, the Orion nebula looks fine, but I move to Saturn and the image is almost unrecognizable. I'm getting to where I can take some pictures with my digital camera. As soon as I get some reasonable skies I'll try to take some pics and send them. Thanks for your interest and help! TravisMike here: When you view Jupiter, how do the Galilean Moons look?
They appear as points of light. Actually, what I'll do is go out tomorrow night (we're all clouded in tonight) and do a more precise description using a number of objects. In fact, I'm going to an overnight star party Tuesday night, which will likely give me a chance to develop a more detailed description. Thanks yet again Travis
Subject: Improving Image on an ETX70 Sent: Saturday, May 15, 2010 05:33:11 From: Travis Whitlow (email@example.com) A long time ago I was given an ETX70 OTA that had gotten pretty badly beaten up as a floor model at some store. The optics seemed ok, so I made the necessary repairs and turned it into a decent spotting scope that I mount on a photography tripod. I also bring it along and use it with a low power eyepiece as a "rich field" scope on my Star Party trips. But as much as I like this little scope, it has always had one major problem. I think it's called coma. If I point the scope at anything bright (like planets) the image is distorted and won't come to focus. Any other objects (namely stars and deep sky objects) look fine. And it performs well in daylight, too. I've switched out the objective (from another ETX70) the flip mirror (from a broken ETX70 on Astromart) and the problem remains. So it seems that the problem might be bad collimation. So I'm wondering, is there's a way to "play" with the collimation on this OTA to improve the images on planets? I really like this little scope, and if I could fix this one problem I'd like it even more! TravisMike here: If stars are pinpoints but planets look fuzzy, it could be that you are trying to use too much magnification. You can check for optical problems with the objective lens by using an eyepiece at the rear port of the ETX. You will need a "visual back" to hold the eyepiece. If the view is better "straight-through", then it is likely the flip mirror (alignment or surface) is at fault.
Thanks Mike! Yes, I've tried the "straight through" versus the "flip mirror" and found there was no difference (but I replaced the flip mirror anyway). The distortion I referred to is actual elongation of the planet (Jupiter really shows it) and it happens regardless of what power/eyepiece I use. The focus is so bad you probably wouldn't recognize the image as a planet. What I've finally blamed it on is bad collimation, so I was wondering if anyone has (in your experience) identified collimation as an issue and, if so, been able to do anything about it. Thanks again, TravisMike here: Lets confirm something. You said earlier that stars looked fine. I assume by "fine" you mean that they appeared as crisp points of light. That is as it should be. But if stars are fine, then planets should be as well. If you focus on a star and leave it set that way, how does Saturn or Jupiter look, or even the moon?
Subject: Meade red dot finder Sent: Friday, May 14, 2010 11:49:36 From: Michael McEwen (firstname.lastname@example.org) Is it possible to buy one of the Meade red dot finders on the current EXT90AT and put it on my original ETX-90? I know there are plenty of red dot options out there, but I thought a Meade original part might be the best way to go. Clear skies, MikeMike here: Not easily. You would have to make a mounting bracket for it and supply power.
Dang it! Well, I guess I'll go with the Rigel Quik Finder...it looks like about the simplest and functional alternative...unless you have a stronger preference. Thanks so much for you terrific site and all the work you do for us ETX users. Clear Skies, MikeMike here: The Rigel QuikFinder is a popular solution. It, and many others, are reviewed on the Accessory Reviews: Finderscopes page.

However, yesterday I had alot of trouble in taking the protective cap off from the camera holder on the telescope. This morning I still couldn't take the cap off. Do you have any tip in taking off the cap? Thanks! Good website by the way!Mike here: See the item "Q. I can not remove the aperture or rear port cover or loosen the Declination/Altitude scale knob.

Subject: Re: General Meade telescope suggestions Sent: Wednesday, May 12, 2010 15:21:42 From: James Roberts (firstname.lastname@example.org) I noticed something this afternoon with my scope that is bothering me. My scope seems to hesitate for a few seconds before it starts to slew. I noticed it when I was viewing a terrestrial object. I was watching an owl creep sideways on a branch. When I tried to slew to the left or to the right, the scope seemed to hesitate, kind of had a little "jump" to it. I then checked the Up and Down slew, same results, minus the "jump". I hear the motors creeping along (slew speed is set at x8 or x16), but it takes a couple of seconds for it to actually start moving. It does fine when tracking an objuect though. Is this "hesitation" normal and I am just being paranoid, or should I open it up and check everything over aagain?Mike here: Some "hesitation" is normal, however, you can adjust it. See the article "Calibration, Training, Percentages" on the Helpful Information: AutoStar Info page. Be certain to CALIBRATE MOTOR and TRAIN DRIVES and then see how the performance is before modify the percentages.
Subject: General Meade telescope suggestions Sent: Wednesday, May 12, 2010 07:09:17 From: James Roberts (email@example.com) I was finally able to take my scope out and view some planets and stars. I had to make a repir to the RA drive system, and it performed flawlessly. My ETX-60 is a very nice little scope, however, I wish to view objects that I believe are way beyond its capability (like the Horsehead Nebula, the Cassini Gap in Saturns rings). What do you recommend to use to view such detail in planets and deep space oblects? I myself thought about purchasing an LX series 8", but was told that that would not work. Please let me know what you suggest. Thanks! I am glad I finally found a hobby, other than fishing, that I really love.Mike here: The Horsehead Nebula is a very difficult object. I've only barely been able to detect the nearby nebulosity with my 8" LX200-ACF from my dark sky location using averted vision. However, the Cassini Gap (when the Ring System is more tilted than it is now) was seen in my ETX-70AT. So, if you want to see details in faint DSOs, you'll likely want to get a large aperture telescope and do your viewing from a dark site. Get the largest one you can afford and you can set up (unless you have a permanent observatory).

Subject: ETX90 Sent: Tuesday, May 11, 2010 08:15:03 From: email@example.com (firstname.lastname@example.org) Anyone please help I bought the above used, was working perfect, then declinatin stopped. After that I started cleaning and adjusting per the fella from scopetronix. I noticed the declination nut at the end or top of the worm gear is tight as a drum . Is it correct that it should just be snug to prevent up and down play of the worm gear. I'm 69 and I have never been totally in a real dark sky and in to weeks i'm going to Wyoming. Also don't feel or hear the motor running. Should you be able to rotate the white nylon declination gear with you thumb? Sincerely Fred LeverenzMike here: If the Right Tube Adapter has failed (typically from overtightening the DEC axis lock), see the article "ETX-90EC DEC fix (Right Tube Adapter repair)" on the Helpful Information: Telescope Tech Tips page. If the adapter has failed, the lock will not lock and so the telescope tube will not stay put if you raise it. However, if there is no sound from the motor when slewing upwards using the handcontroller, then there is a different problem.
Subject: ETX125EC Sent: Monday, May 10, 2010 20:27:45 From: email@example.com (firstname.lastname@example.org) With standard controller won't slew right or left. Up and down works fineMike here: Have you tried changing the slew speed? Have you changed the batteries? Do you have an AutoStar handcontroller? If so, does it work?
Yes I have tried different speeds. And no I don't have autostar. I'm using a 12 volt ac adapter. I kinda think my grandkids rotated the scope with the locked. The motor runs when you try to slew right or left but scope does not move. With the lock on could the gears or clutch be dammaged by rotating it manualy? I suspect ill have to send it back to meade but any help is greatly apprieciated thanksMike here: First, be certain you are using a good AC adapter. Some can cause problems with the ETX. You might check using internal batteries just to confirm the problem is still there. If the lock is not fully engaging, then the telescope will not move. You can easily check this; lock the axis and try slowly moving the telescope horizontally by hand. There should be resistance. If the telescope easily moves when the axis is locked, then either the lock has failed OR you just need to adjust the position of the lock lever. If the lever needs to be adjusting, see the item "Q. I can not move the Right Ascension (azimuth) lever enough to fully engage the lock. What should I do?" on the ETX FAQ page.
Subject: General ETX-60 Question Sent: Friday, May 7, 2010 09:07:44 From: James Roberts (email@example.com) I have attached a couple of pics that I got from the Tech Tips portion of the Mighty ETX site. My RA drive quit working, and needed an idea on how to repair it. As you can see, this user repaired his with a spring loaded bolt, drilled into the metal plate, so that it pushes against a molded- in"c-clip" portion of the worm gear housing. This "c-clip" was entirely broken off of mine. I placed several thick washers, wrapped in a thin strip of duct tape, around the metal plate, and it presses the worm gear aginst the main gear permanantely. The worm gear housing can no longer has the flex to move back and forth. The question is this: Does there need to be tension against the worm gear to main gear housing?
Okay. The gears will not lose contact with the way I have fixed mine. I just wanted to know why Meade had molded in some type of tension spring.
And an update:
I got it fixed. I used the same concept of drilling out the small metal tab, only I put a 6-32 set screw to hold the worm gear against the main drive gear, not too much to create stress on the motor though I did not need to use a spring loaded bolt. . I then loc-tite it in place so that the bolt don't back itself out. All is good, for now anyways. Thanks.
Subject: Re: Smart finder shuts down unexpectedly Sent: Tuesday, May 4, 2010 13:48:41 From: Ross Elkins (firstname.lastname@example.org) Here's a little tidbit. I have the original owners manual for the PE and on one of the last pages it has a replacement guide and spec for the battery. It says use a CR2023. When I stopped by Radio Shack, not only did they not stock this size but their docs didn't have a listing for it. I took a look at the actual battery in my late model LNM (replaced by original owner after breaking it off!) and found a CR2032 in it. So either the Meade tech writer is dyslectic (like me) or its some old/discontinued battery model. I found the 2023 on the internet but the packages for sale were actually 2032's. Must be an older model number as I suspected. Ross
From: Mike Hogan (email@example.com) The Smartfinder uses the main 'scope power, not the LNT battery but it does have an auto timeout. You can always turn it back on and off using the "0" (light) key on the Autostar keypad. Regards, Mike Hogan
Thanks for forwarding the tip. Too bad I went thru the job of replacing the battery yesterday. :-(Mike here: Apologies. Now you have a spare.
No problem. What a crummy procedure for replacing a simple disc battery. Meade engineers must have had their heads screwed on backwards. Unlike previous posts though, I had no trouble with the length of the wire to the red dot diode. Maybe the LNT's with the vertical display lens like mine didn't have this issue. I removed the internal circuit board to replace the battery as I felt the entire assembly was to fragile to pry the battery out from the bottom of the unit. Used a toothpick to hold the side spring in place while getting the cover back on. It slipped out thru the exit hole on the far side from where the adjustment screw enters. I've been an electronics/computer tech for 30 years so I'm usually better off than most for this kind of work. Ross

Ever seen this issue and is there some shortcut key combo on the autostar for turning it on/off? TIA RossMike here: It has been awhile since I used the SmartFinder but there is a battery saving mode (I believe) that turns it off after a period of time.

I had been talking with another amateur astronomer for the last few months and he decided to sell me his 125PE plus the entire kitchen sink of accessories at a great price. I'm selling my 90 for a reasonable $300 and applying the profit to the 125 so I am finally completely set and all for under $500. For a fellow who is out of work this has been a very satisfying acquisition and hobbyist business deal!!! Now I have something to do nights (and days with my solar filter) that takes my mind as far from earthly problems as the universe is wide. Starry nights, Ross PS here's a pic of my new friend!
Subject: ETX 80AT-TC power problem Sent: Saturday, May 1, 2010 04:38:38 From: Ann Mason (firstname.lastname@example.org) I bought an ETX 80 telescope in UK and flew with it to France (where we live). I put 6 x AA barreries in the battery holder, inserted the Auto star connection in the HBX port and flicked the computer control panel switch to ON. Nothing happened, no copyright message and no red light to indicate any power to the system. Eventually I returned the telescope and collected a new one. The same has happened again, no power light and no Auto star display. I carried the telescope in its original box on the flight to ensure it was not dropped or shaken or damaged in any way. Ive been through the troubleshooting section, checking battery connetions, etc but for no result. Any ideas on what to try next, I cannot believe there could be a manufacturing fault with 2 seperate telescopes. Regards PeterMike here: I don't have an ETX-80 model to check to confirm this, but does yours have the removable battery clip with a 9V-style connector? If so, check that the clip is secure. Also, check the orientation of the batteries in the holder.
