Also, due to my lack of planning, I was thinking the comet was going to be much further up closer to the second star in the big dipper handle. I never was able to see it that night. Just shooting blind with no real hopes of anything. It was just happenstance that the comet is fairly well centered in my shot. The first image is is not cropped, the comet was just pretty much right in the middle of my shot.
The second image is just a crop of the first image.
Better luck next time!
