Hey gang,

I actually set my alarm clock for this very early in the morning on June 8th. It’s a 19min (1min subs) shot of Comet 2009 R1 McNaught and NGC891… it certainly took way more than 19 min to process though! Yikes! Deep Sky Stacker has a routine to stack the comet with no star trailing but unfortunately it wasn’t working for me. So I had to do it manually by running it so that it would stack just on the stars (so comet was blurred and NGC891 was sharp) and then again where it was stacking on the comet (stars were trailed). I blended both images in PS in lighten mode to get this final result. Hope you like it or at least find it interesting 🙂

McNaught, I believe is around mag 6.7 and still getting brighter.

The image below is almost a full frame taken with the QHY-8 and 8in RC (1625mm fl) so the comet is not that small.
