I've been using an older model Celesrton CPC1100. If has been working well until tonight when the altitude drive developed a lot of play in it, like several degrees worth even with the clutch turned down tightly. The scope is balanced so it's not due to that. The drive works but with so much play it does not follow along that direction.
Is there something I can do to repair this sudden problem? This must have been discussed here many times. Or do I have to get it repaired by some professionals?
