A 3 Minute Full Frame Sub on an AstroTrac @ 500mm
Inspired by Mautice Toet (mftoet) recently posting his M45 image and including an individual sub showing the starting point I have decided to share one of mine. I think my most recent imaging session produced my best collection of subs so far. The image shows the corners of an unprocessed full frame raw image captured on a Canon 5D Mark III coupled with the Canon 500mm f/4 L IS lens mounted on the AstroTrac using 3 minute subs (@ ISO 800). Naturally I would like to go deeper (don't we always?),
