Dragons of Ara – NGC 6188 and 6193 – Emission Nebula and Open Cluster in Ara – IAS Hakos, Namibia – Apr/May 2022 v1

Final installment of the OSC data from April/May, taken at the IAS Observatory Hakos, Namibia. Somewhat well-known objects in the southern sky, NGC 6188 and 6193, imaged as a two panel mosaic.

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.

See Astrobin here and here for details.
