Loose dirt on mirror Meade Lx6

Hi, I recently started taking CCD pictures with modified web cam and picked up some particle spots in the frames (same spots on all pictures) I presume that its dust on the mirror of the scope. How do I fix this?

LX6 Hand controller....error message - Meade 8" LX90 LNT Schmidt Cassegrain Telescope with SmartFinder w/ FREE UPS


If the hand controller on the LX6 has stopped working you have a problem since meade does not support this very old telescope. My only suggestion would be to place an ad on www.astromart.com looking for a new hand controller.If the error message indicates a "motor fault" make sure you have a good power supply and or fresh batteries-- as low voltage will cause a motor fault error.Later you said it was an LX90 LNT-- ?? so which scope do you actually own???

Loose dirt on mirror Meade Lx6


Nope, the dust is on the webcam sensor. The telescope mirror is too far away to influence the image. Most modified cameras have no window to keep dust off the sensor's cover. A camera lens cleaning brush works fine. Also, some cameras have 'hot pixels' that are defects in the sensor, and are permanent.

When I press the mode key nothing happens. - Meade 8" LX90 LNT Schmidt Cassegrain Telescope with SmartFinder w/ FREE UPS


Nothing will happen if you at the TOP of the menu tree. The mode key serves several purposes. First it works like the ESCAPE key on a computer and backs you out of the current menu UP in the menu tree one level each time you push it.If you hold it down for 2 seconds you get another menu with additional features..Check your manual for the menu tree diagram. If you are already at the TOP of the menu tree nothing happens.If the key does not work at all then the contact under the key is worn out. You can buy a "kit" to repair the contacts-- but of course you must dis-assemble the controller.

Actually, its NOT about an LX90, but rather my Meade LX6 10", f/6.3 scope...whos hand controller is displaying error messages from the encoders on power up. Can you help me? Great scooe, recent problem, no help from Meade AT ALL. Thanks, Jeff Thompson, [email protected], (336) 712-3341


Thanks Paulmo....but adjustments and cleaning haven't fixed it....and I have tried some other encoders, but they were not successful.....probably since they were NOT the exact matches to the Meade encoders. Looks like NObody has a solution. But keep trying and let me know if YOU haver some success. Thanks again. JeffTcom

Meade LX200R 12" Mirror Lock


The 'lock' is a ring gear that closes a ferrul against the draw tube to restrict its motion. It is not intended to be a hard lock. Try the Meade Advanced Users Group for further tips.http://www.mapug-astronomy.net/

My great Meade LX6 10 ", F/6.3 scope...has developed a vexing problem in the hand paddle controller attached to the RA & DEC encoders. After starting to initialize or boot up....it suddenly goes to ERR message, instead of displaying the coordinates. Meade, of course, disavowes any help under what was termed a "life-time"warranty when I bought the scope. Suspecting an encoder I've tried to locate a replacement for the RA, where initialization reportely begins, but can't locate a match. I've also swapped the identical DEC encorderinto the RA position...but the Error persists. Parhaps the flaw is somewhere else...but only weeks ago, it was all running just fine. CAn you offer any help or suggestions. Thanks, Jeff Thompson, [email protected], (336) 712-3341


My scope sat in a basement for years and when I started it up I got an error the same as you discribe. Through sear luck I found it to be a bad connection where the encoder wire pluged into the battery box.

Meade 10" LX6: I need to find what color wires connect to what pins in the Encoder Junction Box connector. Appears that several may be broken and I don't have a schematic. Does anyone have the schematic for the conncetor to the encoder junction box.

MEADE LX90 TELESCOPE


Had the same problem. Took it to a dealer and we put a new controller on but the funny thing was that my old controller worked fine on another scope but it would not work on mine. Agreed with "Guest" above - Mead's after sales service is bad.
