Description

Last night I ended my long time without astrophotography and went to my dark spot again! My goal was my first ever comet capture and I chose 41P.

Version A: Comet stacking mode: I am not sure why the star trails are faded out, maybe due to the median-kappa sigma clipping. Will try again.
