Comet Lovejoy Shines Green on New Year's Eve

One last post in 2014 ya'll! Here is Comet Lovejoy C/2014 Q2 at 10pm ET tonight, taken with my DSLR on a fixed tripod and stacked in Deep Sky Stacker. In spite of the bright moon, the skies were completely clear and the green color showed up without cheating the saturation up at all!

In Photoshop, I stretched the histogram in levels by sliding the gray slider to the left, then used the eye dropper in Curves to identify the grays and turn them up. Next, I created a Gaussian blur layer and subtracted it to get rid of the slightly red hot zone that I had from not taking flat frames.
