Thanks Dennis.
Knew I could count on you
I committed the usual sin of removing and tinkering to see how stuff works... before knowing how stuff works
I'm sure my PAS is now completely out of alignment and the reticle all over the shop.
At least I'm lucky in that I know how to drift align, which is more accurate anyway.
I think I'll get my mount bang-on polar aligned and then adjust the PAS to bring it back into alignment.
