Jeff,
well done mate. Lovely shot for a first image.
Stars are nice and round, focus seems spot on, with 30sec subs i think your polar alignment must be pretty good too if not spot on. The field flattener is almost not needed, star elongation on the edges is minimal- good scope!
Good advice from Matt. The key obviously will be to move to longer and longer subs to capture more and more data. autoguiding will help.
Good to see the bug has gotten somebody else.
well done
frank
