Hi Scott I used a 28" f4.2 Webster Dob and a TV Ethos 4.7 with Paracorr II and a gazillion shots. It was a night of very good seeing, the photo doesn't do it justice, you should have seen Mars! Unfortunately my shots of Mars and Jupiter never seem to come out at the same level, I think its the colours (or my technique).
I think the 28" scope is what did here. Would love to attach my Galaxy S7 to a scope that size. You can actually adjust the iso to 1250 and take up 10 seconds exposure pictures. Trying it out at the moment as a center piece for a video astronomy setup
