I spent some time last weekend trying to adjust my polar alignment
scope (version 4, "PASILL4") so that the reticle is centered, as
described in the instructions.
After aligning on Polaris, etc, I drift aligned using my STV to see
how close the polar scope actually got me.
The polar alignment with the PAS seemed to be around 10 arc seconds
off in AZ and closer in ALT.
What sort of accuracy are other people getting with the alignment scope?
