Fireworks Galaxy Photographed on 10/02/2016

Last night I pointed my telescope at the Fireworks Galaxy (also known as NGC 6946 and Caldwell 12).  I captured 22 frames with my Nikon D5300 at ISO 1600.  Each photo had an exposure time of 210 seconds. 

Stacking was done with DeepSkyStacker.  I also created 20 darks, 20 bias, and 20 flat frames (exposure .10s).
