10 images of 5 seconds each stacked in AstroArt. AstroArt kills the color unless each RGB channel is stacked individually... which I didn't do. Taken with a Nikon D100 with a Sigma f/2.8 70-200 APO lens at 70mm. Lights from Bellwood seriously impacted image as you can see. Taken mounted on a tripod. The comet tail can be seen slightly to the left going above and below the comet. Image was resized and cropped. Procyon is the star on the lower right.
