Description

This is a LHaRGB image of M101 (and NGC5474) in Ursa Major. It is my first galaxy image with a monochrome CMOS camera. It took a while to figure out how to add L and Ha to the RGB data, but I am quite happy with how it turned out, considering it is my first galaxy pic. If you have any advice or comment on acquisition or processing, I would be very happy to hear it!
