Hi Folks.
A question regarding calibrating polar scopes in general and if it makes a difference a Sky Watcher Star adventurer.
I have checked my polar scope as explained in the manual, line up on a fixed target some distance away, rotate the finder 180° and see if the cross remains centred.
I used a power station chimney about 750 yards (m) away and the intersection of the cross was off by just over the thickness of the line in both axes, is this close enough or should I risk making things worse by trying to improve it?
Thanks in advance.
Cheers, Graham.
