Description

M101 was one of the earliest real efforts I put into doing AP "correctly". That effort is also in my Abin gallery.

I felt like it was time to revisit M101, years and much effort later, as a bit of an AP pop quiz. From gear, to methodology, software, and experience, everything is different now than it was then. About the only thing this session had in common with the one years ago, is that they both are data from single night sessions.
I think it's a bit of an improvement.

Clear skies!
