I'm new to this forum and would like to discuss a problem
I'm having with my Meade 10" LX50 SCT telescope.

Recently, we moved to central Florida. The telescope was stored in
the Meade cloth carrying case with foam protection inside. In
the process of setting up the telescope I encountered my problem.

 

The fork arms are not able to rotate on the R.A. setting circle.
The R.A. Lock is in the open position (all the way to the right). 
The R.A. Slow Motion control knob also resisted hand turning.

When powered up, all of the electronic devices work just fine.

 

I removed the plate from the underside of the Drive Base, inspected the worm
drive and it has ample lubricant around the teeth. The Declination
Slow-Motion control knob works without difficulty.

 

I contacted Meade and they were not able to help, as the telescope is
20+ years old. They suggested I contact a site like yours for comments.

 

Thanks for your feedback!

I would look at deforking the OTA and get a new mount. It will probably be less painful in the long run.

"The R.A. Lock is in the open position (all the way to the right)."

 

Perhaps the RA Lock Knob needs adjusting, it may not be fully disengaging the lock.

 

The knob is held on by a small Imperial sized Allen screw.

 

Loosen, rotate the knob on the shaft a bit towards the lock position, tighten.

 

The knob should now be able to move the lock further toward the unlock position.

 

Ideally the knob should be positioned to firmly lock and unlock before running out of range.

 

Defork ? Oh the Consumer Society, don't fix it, junk it.

I'm going to hold off de-forking the OTA for now. May resort to it though if all else fails.

Each to their own. I think you get better results from newer technology than faffing around with a load of old problems to be fixed- I always ask the question- did the originally owner get rid because they had an issue that was not disclosed?

Just to clarify - Are you saying that the telescope worked fine before you packed it up and relocated to central Florida?

Thanks for the question. Yes. Used it often when we lived in Colorado and it worked fine. I've considered the possibility of possible damage

during the move, but the window for filing any potential claim has closed.
