[g__day (Matthew)]

I've just realised my Vixen Atlux has ALOT of slop in the dec gear - put a slight force on the OTA and it can shift +/- 5 arc minutes - even with the clutch on really tight! RA is perfect but what the heck with the DEC?

Is this indicative of the worm just isn't close enough to the main DEC gear - or is there some other adjustment that is needed?

Can anyone tell me how to diagnose adjust the likely source of this error please?

Many thanks!

Matthew
