Oh, and as far as my rig.... been using the same 14.5” f5.5 Newt for about 20 years now. Sono tube, Dob mount, Osypowsky equatorial platform. It’s strictly a visual rig. The focus is so close to the tube that there’s no way you could get a camera to focus anyway. :)
Oh that’s nice, I love big Dobs. I live in an apartment and don’t have room for such a thing, I need maximum portability in my setup, plus I got bit by the photography bug.
