Hi guys, I want to hear about the good, the bad and the ugly before I buy one of these for DSLR photography. It's just that I don't see many pics on the forum taken with them. It will be for deep sky and some lunar and solar use. General dogs body, jack of all trades scope I guess. I know Lewis had an SW ED100 and sold it rather rapidly, but then he sells everything.
Is F9 too slow for deep sky? I know reduces are available to take them down to F7.something.
