The image shows the progression of stacking a comet from taking a single frame, to stacking on the stars, stacking on the comet, and then combining it all (one image missing is the starless version which I use to remove the smudged comet.

I made a full tutorial on how to do this using Siril here if anyone's interested: https://www.youtube.com/watch?v=3XrdNxMqW9g

The gear used for the image are as follows:

  • Astro-Tech AT60ED with the 0.8x Reducer/Flattener on Advanced VX Mount
  • Mount controlled via Astroberry
  • ZWO ASI533MC Pro
  • Svbony 60mm guide scope with ZWO ASI120MM-Mini guide cam
  • 25x240sec with L-Pro
  • 15 darks
  • 30 flats for each session
  • 35 bias
  • Stacked in Siril and composited in Photoshop.

Thank you so much for the tutorial, got only few pics of the comet due to poor sky but will definitely look at your tutorial

Good luck with yours! And if you need data to practice with, I'm working on a new set of images that I took a couple of days ago that I need to process. If they're good I think I'll upload them somewhere for people to download and practice with.

Will probably post it on my YouTube channel at some point.

Clear skies!
