I bought a used AP-1100/CP3 in December and have been happily using it with my 10" GSO RC (and with INDI/KStars!).
I was wondering, is there any recommended maintenance for the mount, e.g. should I be greasing it from time to time?
I think the RA axis is a little looser than DEC, is there an adjustment screw for the backlash there?
