Just to help fault find can you tell us:

If you have used it for some time and it now doesn't drive properly, can you describe how you balance your scope when you set it up?

I'm really hoping the scope is new to you and you've simply missed tightening the drive clutches on set up. It's a basic little step that I remember not being well described in the manual - it's almost so basic that I think Celestron assume you know to do it! The drive clutches look like the shaft locks on my old samson EQ mount from 25 years ago. Old my old mount I had to make sure the shaft locks were free so the shafts could rotate before I engaged my motor drives. On the CG5 the clutches actually engage the drive train to the servos, so it is only the gear ratio and the resistance of the servo motors that stop you from pushing the scope around. You need those clutches to be locked (i.e. so you can move the scope) in order for the drives to move the scope... I might stop now... I think I've made something really simple sound more complicated than it needs to be!

Good pick up Al – it’s often the simple things that get overlooked.

Cheers
