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.

Thanks let me try that.
