Gso Focuser Question
I was just outside with my 12" GSO scope tonight and every time that I put my 9mm Nagler (type 1) eyepiece into the focuser it seemed to go out of focus,( I have the stock rack & pinion type that came with the scope),. I think that the weight of the eyepiece was causing the focuser to slip, but I'm not entirely sure. Do these focusers tend to move when a heavy eyepiece is used in them ?...can I tighten the focuser so this doesn't happen?..please let me know somebody so that I can fix the problem, or go and get a crayford...Thanks !!!...
