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.

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???

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, JeffTcom@aol.com, (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

I have a piece of meade carp that I have been trying to get a fix for many years. The scope currently performs a very useful service here, it keeps a door open. The problem is that the prism does not connect to the back of the scope as the barrel diameter is the wronge size. Any ideas before I consign this piece of sh*t to the dump!


The Meade 8" SCT LX90 is a very good all round unit. Although angry, you will find it is well worthwhile persevering.The back plate, called the optical back, takes an eyepiece holder into which you can also fit your diagonal prism for comfortable viewing. It is part 3 in the diagram here, Fig 1http://www.meade.com/manuals/TelescopeManuals/LXseries/LX90-LNT.pdf All you need is the right size holder for this scope, such ashttp://www.bhphotovideo.com/c/product/202598-REG/Meade_07182_Eyepiece_Holder_aka_Visual.html Any telescope shop can sell you one, but take care to get one that also fits the barrel of your prism, which will be either 1.25" or 2"

No power There is not even a red light on the side
