warm pixel trails

Interesting artifact is best seen when sequencing through darks. There are two types of hot pixels, those that are constantly turned on and those that come and go over time. I tried lowering the kappa used for BPM to no avail. The solution was to check the box for "cosmetic correction of hot pixels" using the default kappa value.

Just wondering if my solution is recommended or if there is something better?

APP 1.075

And you are using sigma clipping? If it's randomized between subs that should already work. Otherwise if your solution works... great! 🙂

Sigma clipping on the darks? No because I only have 25 darks. Somewhere in the video tutorials I was advised to use sigma clipping only if I have 100 or more. For that reason I use sigma clipping on bias only.

Ah ok, sorry, I missed this to be in the darks. No then your solution is indeed the correct one.
