Squares 3

Squares 3 – Dellbrück, Cologne, DE

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.

IC 1396 – Elephant Trunk Nebula – Jun 2022 Ha BW v1

A quick capture during a clear mid summer night. An “advantage” of the light polution here: even so astronomical twilight isn’t reached, the sky brightness is for approx. 3 hours in the range of SQM 19.5 to 19.9. SQM 20.0 is the maximum I measured in my backyard in spring 2020 with the excellent “lock-down” skies.

Hopefully a break in the currently cloudy and rainy weather for some additional O3 und S2 data during the next days before the moon returns.

IC 1848 – Soul Nebula – Feb 2022 Ha BW v1

Fast schon aus Verzweiflung ;-) zwischendrin ein paar H-alpha Daten vom Seelennebel, mehr war bei Mond und leichter Schleierbewölkung nicht drin, das Wetter in Köln ist leider in den letzten Monaten wenig astrofreundlich.

Nicht die erste Variante, die älteren finden sich im kompletten Artikel.

IC 417 Emission Nebula and Friends – Ha BW – Nov 2021 v1

A completely clear night – not that many of them lately – provided several hours of H-alpha to catch the nebulosities above. Meanwhile I switched from the Optolong LRGBSHO filter set to the new Baader CMOS-optimized filters. At least H-alpha seems to work better in the combination with the Esprit 100 ED and QHY 268M, but still some problems with the flats.

See Astrobin here and here for details.
