Supernova SN 2024abfo in Galaxy NGC 1493 – Dec 2024 – LHaRGB v2

The full frame around NGC 1493 with supernova SN 2024abfo, see marker, and a plethora of smaller galaxies, see the annotated version below.

This image combines RGB data from Nov, more than 12h Ha Data from Nov/Dec and L data from 01 Dec until 09 Dec 2024. Maximum brightness of the supernova was on 06 Dec 2024 at 13.81 mag (L), so this image portraits the supernova around maximum. There was actually not much signal in the Ha data, so the contribution is rather small.
