Description

Made two stacks - one alignment on stars, one using comet-alignment and blended both together using Pixel-Math in Pixinsight. Not 100% happy, but it's just the 2nd comet, (ISON been first) in my astrophotography life, so bear with me.

Description: Made a mask for the comet to protect it, used SCNR to reduce the green in the starfield/background and inverted the mask to raise the saturation in the comet only. ;-)
