Recently, a new type II supernova SN 2024abfo was discovered in the galaxy NGC 1493, on 2024-11-15 by ATLAS, discovery mag 16.793.
This image is processed data from 2024-11-18, I managed to image NGC 1493 and SN 2024abfo on 2024-11-17 and 2024-11-18 so far. Measurements of L brightness in Tycho yields:
2024-11-17: 16.82 – 16.91 mag (median, 2 batches, not reliable, passing clouds)
2024-11-18: 16.70 – 16.64 mag (median, 5 batches)

Took me a while to create something with presentable colors from the narrowband data of this obscure nebula in Scorpius, the previous H-alpha black and white version was easier.
This is a bicolor image with R=H-alpha, G=SII, B=SII and mainly H-alpha with a bit of SII used as luminance, plus calibrated RGB stars screened on-top.

A lesser known object, the Cometary Globule GN 16.43.7.01, nick-named Dark Tower gained some popularity, especially since ESO’s publication of an image taken with the VLT.

Back in Sep 2023 I imaged the close-ups of the Grus Quartet Galaxies, see here for NGC 7599, 7590, and 7582 and here for NGC 7552. Now with the wider field of the IAS remote telescope “Dieter” all four in one FOV. See the annotated version below for the myriads of galaxies (PGC) in the background.

Last night’s full moon at 20:03 UT, almost a super moon, i.e. a full moon at perigee, which will be on 2024-08-21 5:05 UT at a distance of 360193 km. Two days earlier, the Moon here is at declination -14.7°, a distance of 364578 km, aged 13.8 d with the canoncial full moon at 18:28 UT. Combined RGB exposures with heavily boosted colors.
