How did you stack 151 images and show no movement? Or, is it comet stacking mode?

H, The comet moved quite a bit in the 3 hours over the exposure, so two methods of stacking were used, comet stacking for one, star stacking for the other. The two stacks are then combined in photoshop. DSS does similar in comet+star stacking but makes a mess of it.

This PDF goes through the steps on how to do it. http://www.astrophoton.com/tips/comet_images.pdf
