Problem with alignment of Meade LX90 8" telescope




By dcbluedevil7 on Aug 30, 2009

" "
We purchased our LX90 2 months ago and since then we have not been able to align the scope with the "automatic" or "easy"or "2 star" programs. We calibrated the sensors and motor and trained the drives (does this need to be done with each use?) The scope will sync with a planet or star and follow it. After we get a message of "alignment successful ", it slews to an area near the object (for instance Jupiter or the Moon) but the object is not in the eye piece of the LX90 or the finder scope. What else can I do to correct this problem?

Start from scratch-

RESET the hand controller.

Calibrate motors using the same power source you will use outside.

Re-train the drives

Calibrate sensors on Polaris

Use 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

- If this is a NEW LX90 with a hand controller reporting 59ef as the version number, the firmware must be updated. The original firmware had many bugs in the software. Meade has posted a new updater software here about half way down the page. Install this and use it to get the latest firmware update, which it will find automatically. You will need a computer and special cable that is plugged into the bottom of the hand controller to update the firmware.
