if you want to get your drift alignment good enough for photography you will need to use a recticle or your ccd camera and a program with a recticle overlay (i think theres a few free ones?) and drift align at the focal length you will be imaging at or more, slow drift is still drift and it will cause egg shaped stars or trails that even the best apo wont fix
plus, if you have a permanent setup theres no excuse!!!
close enough isnt good enough especially in that case
nail your alignment then take a few more images and see if you still need the new scope
