Meade Zero Shift Focuser Maintenance
My Meade zero shift focuser is struggling to move in with the weight of a SBIG St8 ccd attached. Moving out is not a problem.
What sort of maintenance do I need to do?
As an aside, what other zero shift focusers are available for 14" ACF Meades? The focuser also needs to be able to be plugged into a PME mount and controlled by TheSky.
