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.

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)

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.

Almost exactly 10 years ago, I photographed the magnificient Pavo Galaxy with the IAS 20 inch AK3, my first object with such a “big scope”. Here’s the result of June 2024, with much more exposure time on the very same telescope. I originally planned to use my QHY268M with the AK3, but this camera is now used at the new IAS remote telescope. So back to the roots with a ASI294MC Pro one-shot-color camera.

Only three of the quartet, NGC 7522 is a bit further out, but NGC 7599, 7590, and 7582 just barely fit the frame. Data from September at IAS Observatory, Hakos, Namibia.
