Ends up this is a very easy fix, thankfully! The inner and outer parts of the secondary mount are threaded together. Remove the 6 screws holding the 8" ring that secures the correcting lens, remove the ring, and then pull the correcting lens out by the secondary mount. Finally, hold the inner and outer parts of the secondary mount and tighten them together. Put it all back together. I have read that the orientation of the mirror is important, and I think I have it close to the original orientation. Will be testing it out tonight.

I just created a video and it does sound like the same issue you had Tomi. I am nervous about removed the correcting plate, but it does appear to be 7 bolts to remove and it would come off. Thanks for the advice! https://jakethesnake.net/Telescope-Issue/GOPR5573-1.MP4 Are there any good threads on here about removing the correcting plate on an 8" LX200GPS that anyone can point me to? I've search some but haven't found anything yet.

Hello All, I purchased a used Meade LX200GPS last year (used, purchased new in 2006) and am slowly trying to learn how to use it and get it dialed in. I am new to astronomy but I did help a friend figure out how to use a similar Meade telescope in the past. It seemed to be fairly well collimated when I first checked it. Recently we have been looking at Saturn and Jupiter and noticed it seems a little blurry. I found a document online that talks about fine collimation and decided to try. When I did I noticed the secondary mirror is not well mounted in the correcting lens. The entire assembly will rotate and even wiggle some. I have the 6 screw secondary. I tried tightening the 3 outer screws a bit and that did not seem to help. They seem tight enough already and I don't want to tighten them anymore without some advice. Has anyone here had the secondary assembly get loose and if so, how was it fixed? Thanks, Jake in Austin, Texas
