Description

I was traveling when the comet was close to M3 so I missed that chance.  This data was taken on December 6th.  There is nothing special in the star field except for a couple of small galaxies. 

R = 10 x 120 sec bin 2x2
G = 10 x 120 sec bin 2x2
B = 10 x 120 sec bin 2x2

Total integration = 1 hour

Capture was RGB, RGB, RGB repeated ten times to maximize comet movement in each master.  Processing was in Pixinsight using Comet Alignment, Image Integration with suitable pixel rejection settings,  Dynamic Alignment to create comet only master,  and Pixel Math to combine the stars and comet.  Final stretching and color adjustments were done in Photoshop.  This is tedious process at least for me...I wish there were an easier way.
