Focusing Adjustment and Polar Axis Alignment
Polar Scope is a very delicate optical component, especial its reticle which is made from a glass
and mounted on a plastic fitting. If your polar scope axis needs to be re-aligned to the RA axis of
your EQ mount, please do not use excess force onto the reticle adjustment screws.
