It maybe distortion from the F3.3 reducer or more likely an aspect ratio problem. The dimensions of the pixels in the Stellacam2 aren't equal in size. I have been scaling the 640x480 images to 640x432 to correct, but that may not be the correct ratio. I've been intending to look up the pixels size, thanks for reminding me!

You can really see the tail. Do you think the elliptical shape of the comet head is a result of the time-exposure? Great image. You can really see the tail.
