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.
More details at Astrobin coming soon.

CG season is also rain season in Namibia, so it took a while to gather enough data for image, adding to the growing catalog of CGs here.
More details at Astrobin coming soon.

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.

It took a while, but now round three of the Squares made it to my website. The images from 2022 to 2024 were already published as a photobook.
Es hat ein Weilchen gedauert, jetzt ist die dritte Runde der Squares auch hier auf der Website zu finden. Als Fotobuch sind die Fotografien von 2022 bis 2024 schon etwas länger verfügbar.

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.

After a looong time, a total lunar eclipse was visible from Cologne, Germany. The last time I photographed a lunar eclipse was back in 2019!
Nach laaanger Zeit war endlich wieder eine totale Mondfinsternis in Köln sichtbar. Das letzte Mal habe ich eine Mondfinstern 2019 fotografiert.
Local circumstances (local time = CEST):

Has been quite a while since I last imaged this large, beautiful spiral galaxy in the southern constellation of Sculptor, NGC 253 known as the Silver Dollar Galaxy, Silber Coin Galaxy, or just Sculptor Galaxy.
A lot of H-alpha data has been used, thus the rendition is different from the DSLR attempts back in 2016.
