Notes:

The image data was processed twice: once on the stars (to reject the moving comet) and once on the comet (to reject the stars). The two images were overlaid in Photoshop so that the detail around the comet could be seen in addition to the fainter parts of the comet tail. There are still remnant of the star trails visible in the image, giving it a sense of motion.

The comet image is "stretched" much more than the star image.
