I have a similar situation. I have the opportunity of purchasing a 50mm Celestron Axiom for a really good price. Would I be better off with a shorter focal EP? My 12" LX200 GPS is F10 with a focal of 3048 mm. So 50/10 = 5, or 40/10 = 4, or 32/10 = 3.2. How do I figure which exit pupil is best for me?
