It’s been almost a year since my last blog update on this topic and I’ve made some progress. I’ve got a new camera and a Sky tracking mount. Sadly I still live at the same place which is heavily light polluted (Bortle 7), but I’ve managed to get some decent results by traveling a bit further north.

Not using any special filters this time either, which made it even more challenging. I’m still using the old Sigma 80-400 lens (in all honesty - not very good as it’s very dated at this point). I’ve got more modern stuff as well but none have the necessary reach for deep-sky objects.

Below is the image I’ve taken with this setup.


  • Canon R6 + Sigma 80-500mm lens
  • Sky-Watcher Star Adventurer GTi
  • 100x 30s exposures @ 400mm, ISO 3200
  • No dark/bias/flat frames (I know, I know…)


  • Stacked in DeepSkyStacker
  • Processed in Siril (Background extraction, Color corrections, initial stretch)
  • Processed in Photoshop (Curves, Levels, Color corrections, Noise reduction, Sharpening)

Next: I need to think about getting that Telescope…
