RCW 32 – Gum 15 – Emission Nebula in Vela – IAS Hakos, Namibia – Apr 2022 v1a

Another image from April at the IAS Observatory Hakos, Namibia. Designated RCW 32 or Gum 15, an emission nebula in the constellation Vela.

Meanwhile I started using PixInsight’s new Weighted Batch PreProcessor (WBPP), with the option to split the R, G, B channels in the Debayer process and align / integrate the channels separately. This really improves image quality with OSC and using WBPP takes over the otherwise tedious manual process.

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.

Deep Sky 2017-2020

Tja, was macht man, wenn das Wetter nun schon wieder zwei Neumondperioden ohne Clear Skies hat verstreichen lassen und der Ausflug in die Weiten und den dunklen Himmel von Namibia Corona-bedingt ausgefallen ist?

Genau, in Erinnerungen schwelgen. ;-) Daher habe ich eine Auswahl von Deep Sky Aufnahmen aus den Jahren 2017-2020 als Video zusammengebaut. Da seinerzeit superproduktiv, dominieren die Hakos-Aufnahmen von 2019. Enjoy!
