Cannot seem to balance my C4-R refractor on its CG5 mount. When I do have it balanced you need arms like a baboon to operate slowmotion controls. Have installed a drive and have imaging gear.
Can any one help.
Early versions CG5 had problems with axis grease hardening.
I understood this problem had been solved by Celestron.
I have a C6R-GT go to on the same mount and I notice that it has become a bit stiff to move by hand but motor control is perfect.
(Because of where the problem lies the motors are not being strained at all.)
If its out of guarantee see following link for a cure:
