Ted, Great site you have here. Great to see your setup. Maybe I've rediscovered a hobby for my upcoming retirement. I'll let you know what I decide to do about the scope. I really enjoyed browsing the gallery.
Time prevents further exploration now.
I'll get back to you. Boggles the mind to think of the time and distance involved. Also I'm going to try diffraction focusing and see how it works for me. Presently I'm using a hartman mask. With a little practice you'll really be good.
