Meade 10'' LX 10 will not focus

My Meade 10" LX 10 wont focus properly

    This is an OTA that I won two months ago on ebay as a transportable OTA for my CG-5 mount instead of transporting a more bulky LX200R with tripod and mount. My LX10 series OTA focuses at low magnification (50X, with a Televue 40mm plossl) but not at higher magnifications. All the eyepieces used are quality eyepieces that work well with other telescopes Looking closely at the mirror it appears that there are cleaning marks from a previous owners attempts at cleaning or something got onto the mirror and noticeably degraded its quality. Also, the quality of a one owner telescope mirror can degrade over time and that can affect focusing as well. Mass produced telescope mirrors vary in their quality control. Another possibility is that something is wrong with the focusing knob and how it moves the mirror. Clearly there can be various problems when purchasing used OTA's or when they have been used over a long period of time and storage. Since the OTA came with one of the cheaper Meade 1.25" diagonals that could be a part of the problem as well. I dont have a quality 1.25" diagonal to test since this OTA takes only 1.25" diagonals. I have other Meade LX200R telescopes that I purchased new and from my experiences with one of them being sent to Meade for repairs - Meade's service leaves much to be desired, is costly, and they wont tell you what they did to the telescope!!. Customer service stinks and tech service gives different answers to the same questions on different days!. When the weather presents very good seeing conditions I will give the Meade OTA a more thorough series of tests. O.W.L. ( does refurbish OTA's and recoat mirrors but it can be expensive and ?: is it worth the expense for LX10's and older OTA's If you find any solutions please e-mail at thanks

Is this an LX200 or an LX255 which I have never heard of.

Does the scope focus on a distant object during the day time? If YES nothing is wrong with the scope.

The eyepieces determine what the magnification will be. The eyepiece with the largest number on it is the LOWEST magnification. Meade has a web site with all of their manuals here:

Check the autostar controller; you may have a stuck key. The telescope should run without the control - unplug it after it starts and see if the slewing halts. (don't plug it back in while powered) The other thing, would be a bad sensor on the motor.

No schematics out there for that model, although there are ones for the LX classic and GPS. The center contact is positive.

ETX 125 Loose image when focusing

The ETX family (and other Meade LX telescopes), use a moving mirror system for focus. The focus knob moves the main mirror in and out. For smooth operation, there is some slack on the central tube that allows the mirror to rock slightly as it moves. That is a normal condition, and the movement is magnified, the greater the magnification of the eyepiece.

Stripped gears on the focuser

Meade will not have parts, focusers are always replaced as an entire unit-- but if the mirror is still good you can buy a replacement focuser here:
