      I'd just image the comet guiding on the star field. Use exposures short enough that there's no apparent comet movement in a single image. Take the calibrated images and align them twice; once on the star field, once on the comet. Combine the two images using the comet from one and the star field from the other.

      I use ImagesPlus for my image processing. The latest beta includes a new tool that uses a mask to separate then recombine an image into stars and extended object(s). This makes this type of processing easy to do.
