NGC 3660, SN 2026cff, and PGC 1000714 – Galaxies and Supernova in Crater – OSC v1

First result from this year’s trip to Namibia, including two nights at the IAS observatory on the Gamsberg plateau using the mighty 28 inch Newtonian telescope for astrophotography. I came across this field of view when observing the supernova SN 2026cff in NGC 3660 with the IAS remote telescope and noticed the near-by, peculiar Hoag-type galaxy PGC1000714 with its ring structure.

CG 10 – Cometary Globule in Puppis- LHaRGB v1

Continuing with the CGs, this one took really loooong, from mid January to mid February. Alas, CG season is also rain season in Namibia. Good for the country, but not so much for astrophotography.

Part of the ever growing CG catalog here at Photography > Astrophotography > Cometary Globules.

As always, more details at Astrobin.

Cometary Globules CG 15 and CG 16

CG 15 and CG 16 – Cometary Globules in Puppis/Carina – LHaRGB v1

Another CG image, completed just after Christmas Day, showing CG 15 (lower right) in Puppis and CG 16 (upper left) in Carina. Two more for the growing catalog of CGs here.

Sculptor Pinwheel Galaxy

NGC 300 – Sculptor Pinwheel Galaxy – LHaRGB v2

Difficult processing with these data: separating stars and galaxy with StarXTerminator doesn’t work well here, too many artefacts. So all the stretching was done with the starfull images, with just a bit of star reduction on L, to preserve the many little, mostly blue stars in the arms of NGC 300.

A Narrowband Helix

NGC 7293 – Helix Nebula in Aquarius – SHORGB v1

Some old narrowband data of the Helix was sitting for quite a while on my hard disk. Recently I started to adopt the “Foraxx” palette described in The Coldest Nights blog and used this technique with the SHO data, but combined both the SHO Foraxx and Bicolor Foraxx results, with a bit of RGB mixed in, and added RGB stars. Hope that the result isn’t too bad. ;-)

See an older post for a “classic” rendering of NGC 7293.

Quarks Beitrag – Die Mondtäuschung – mit Joana Abondo

Am 9. Oktober war es dann soweit und die Quarks-Sendung “Zurück zum Mond: Der neue Wettlauf ins All” mit unserem Beitrag “Die Mondtäuschung” im WDR-Fernsehen zu sehen. Hier im Standbild mit Joana Abondo. Der Dreh mit Joana, Jakob Kneser und dem Filmteam im August hat großen Spaß gemacht.

Took a while to get this short time-lapse of the total lunar eclipse on 07 Sep 2025 online. Photographed at Frankenwerft, Cologne, Germany near central station.

Hat ein Weilchen gedauert, dieses kurze Zeitraffer-Video der totalen Mondfinsternis vom 7. September 2025 online zu stellen. Fotografiert auf der Rheinuferpromenade, Frankenwerft, Köln in der Nähe des Hauptbahnhofs.
