Counterweith shaft broke off


Bring the broken parts to a local proffessional machine shop. It will no doubt cost a bit, but they should be able to do it. No, epoxy won't work.

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.

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???

LX90 8" LNT Polar alignment


The only reason you would want to polar align is to do astro-photography which will be difficult from your location.Use the scope in normal ALT AZ configuration. Calibrate motors, Train Drives, make sure time, date, site, are set correctly. The Calibrate sensors function sets the magnetic deviation for your SITE. Not really that important because when you center two alignment stars everything is corrected anyway.So take the wedge off the tripod --- you can still do short duration astro-photography usually not exceeding 12 second exposures and then STACK the images using software.

Problem with alignment of Meade LX90 8" telescope


Start from scratch- RESET the hand controller.Calibrate motors using the same power source you will use outside.Re-train the drivesCalibrate sensors on PolarisUse either the 110 volt power cord, or buy a 12 volt power pack and the proper Meade 12 volt cable. (www.scopestuff.com carries the right 12 volt cable)If your scope is NOT the LNT or GPS model you must level the tripod before you align. Go to home depot and buy the $3 small plastic two way bubble level, or the bulls-eye style bubble level.Further trouble, I suggest going to the LX90 Yahoo group forum, and asking questions there.Good Luck

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/

Leveling sensor seems to be inoperative, tube continues to slew along vertical axis until I have to turn off the computer to avoid damage. I have replaced the 3 volt battery in the Smart Finder, which, I understand, is the LNT device.


Probably your hand controller cable is broken. First thing to try is a new hand controller cable.Also check the small watch style battery inside the LNT module.If a new cable and a new battery do not fix this then it an internal circuit gone bad. Only Meade can repair this:http://www.meade.com/support/index.htmlTry the new cable first.
