ETX-90 Wobble Fixed
One thing that annoyed me was using the horizontal tracking knob always seemed to snag or hang. It became far more pronounced when I hung my camera and lens projector on the back of it.
So as a Sunday afternoon project, I decided to dismantle my telescope bottom side. Immediately saw what the problem was. The center screw was loose. Tightened it up and then found that to get it tight enough to not have any tilt, it was too tight to function. Was sort of dismayed that there were no washers or dry graphite present.
Found a piece of clear plastic from something I purchased, cut two washers out and punched holes in them. Took the screw out and put them on it and tightened it back up.
Working much better now but now I want to disassemble the whole thing and fix all the points that could cause binding.

Re: ETX-90 Wobble Fixed
Sorry, had issues with my Mac.
Took this one the other night playing around with a Meade #64 / 07363 prime attachment with both sections attached.
Getting ready to start playing around with a Meade 07361 lens projection attachment to see what I can get.
What my rig looks like.
