Geoff,
I wouldn¡¯t worry about polar alignment if using the AAP as the AAP has a pretty good routine and easy to follow. It uses the primary scope and camera so no additional kit needed.?
I can get a good enough polar alignment for 10 min guided subs (I usually do 5mins though) in 2-3 minutes most nights. It also means no bending down or kneeling on concrete or in puddles to crane your head into a polar scope! Always a bonus!
Enjoy
Bryn
