M81 Bode’s Galaxy and M82 Cigar Galaxy in Ursa Major – LHaRGB v2

Old data revisited: 3 years ago, back in 2022, I collected a whopping 38 hours of data on Messier 81 and Messier 82, a nice field of view with lots of smaller galaxies for my Esprit 100ED APO at home. But I never managed to get to a satisfying rendition up until now. The new NoiseXTerminator version AI3 was released at just about the right time. Under suburban Bortle 5 skies, this massive amount of exposure time is really necessary to bring out the dust streaks.

Supernova SN 2024abfo Update

Lightcurve of SN 2024abfo from 17 Nov to 31 Jan 2025
Lightcurve of SN 2024abfo from 17 Nov to 31 Jan 2025

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 15.65 mag on 31 Jan 2025.

Cometary Globule CG 5 and Dark Friends in Puppis – LHaRGB v1

Still on the hunt for cometary globules, here’s CG5 trying to escape the evil clouds with tendrils already stretching in its direction … ;-)

Meanwhile, I created an extra page in the gallery with some information on CGs and the related astrophotography so far.

Cometary Globules CG 3 and CG 25, Galaxy NGC 2427 in Puppis – LHaRGB v2

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.

CG 1 and 2 – Cometary Globules in Puppis – HaRGB v1

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.

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.
