Comet Johnson

As promised, here is Comet Johnson from my imaging session on Monday, May 15th.  My light box is still not operating properly so I didn't take any flats to correct for the vignetting and other gradients. That is the reason for the slight ring-like halo around the image. And since I didn't have flats I couldn't stretch the image as much as I would have liked, but the result is not all that bad.
