I was originally going to take 120 second subs, but it was trailing noticeably. I'd like to get a good image but I'm having trouble stacking it is DSS. I'll keep working on it.

It seemed to be best to only use 10 lights. I then registered them with a 2% star detection threshold. I then selected the comet in each frame. Stacked with Comet + Stars, then stacked with Kappa-Sigma clipping. DSS also had a couple minute "Not Responding" perion between the star stack and comet stacking phase.

With over 10 I get diagonal noise and gradient rings in the comet.
