5 x 60" ISO/Gain: 1500

The previous night, I captured the classic minimum gain with 90-second exposures—60 frames.

Each series was about 3–5 minutes long (the comet doesn't move far in that time), guided on a star, and all shifts were removed. I stacked everything and found that the best result was 5×60 seconds. Processing done in PixInsight.  <br><br>Capture date: 19/01/2023 22:48 UTC
