All my comet shots have been either handheld or on camera tripod. I always try for exposure of the comet, basically longest exposure time before stars streak. I recently reprocessed my old comet shots and got significantly better results. I used PixInsight's comet alignment feature to align the shots on the comet, the stars then either streak or disappear depending how I stack. Its significantly better than using the other alignment options and gave me faint tails I couldn't reveal when i originally processed the shots. The hard part is finding the comet in the shots to mark for the alignment.
