Continuing the hunt for cometary globules, those strangely shaped dark clouds, mostly in the constellation of Puppis. This image shows CG3 and less prominent CG25 to the right, together with the spiral galaxy NGC 2427.

Since the previous post, SN 2024abfo‘s brightness has been increasing steadily, peak L/V brightness was during the night 06 Dec 2024, at 13.81 mag, more than fifteenfold since discovery by ATLAS on 15 Nov 2024 with 16.79 mag. Meanwhile, back at 15.38 mag on 13 Jan 2025.

Technical details see previous post. Photometry measurements with L filter.
It took me almost a month to gather the data for this 4 panel, 2×2 mosaic of both CG 1 (lower left) and CG 2 (upper right) in the outskirts of the Gum Nebula. This processing uses RGB and Ha data only, merging L didn’t yield good results with the “red wall” on the right.

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.

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.
