My load is a GSO 8 inch F4 Newtonian (which is very good BTW), I have to have both counter weights attached near the end 3/4th of the counterweight bar. |
Lithium grease or synthetic chain grease applied to the threads of the Az and Alt bolts will help with your PA adjustments
I have 2 off EQ6-R mounts at different locations and PA adjustments in Alt are definitely tighter than adjusting the Az bolts. To get below 1 arc minute PA error sometimes I’m just applying only squeeze tension ( hardly even moving the bolt ) to the Alt and Az bolts during Star centering procedures.
