I recently obtained a Meade LX70 M6 Mak. It's in great shape. The one thing that i would like to try to improve is the smoothness of the focuser knob. It seems a little "sticky" or "tight" in that there is just enough friction to resist the turn that i end up over focusing when trying to make very small fine focus adjustments with it.
I see the 3 small screws around the collar, but am looking for any advice before I start unscrewing things to try to explore. Might this be as simple as getting that knob off and applying a bit of lubricant someplace? Will continue to do my Google-research, but figured I'd get in front of some experts first.
