Description

Revision C/D: Came back and reprocessed this from scratch; it came out better, but the data is clearly not as good as in my later pictures.

Revision E: Another reprocess from scratch; starting a project to reprocess all my messier objects and get my Messier 40 imaging badge on AF.net :-)
