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.

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.

Night in Namibia 2022

Night in Namibia 2022 – Time-lapse Video

A new night sky time-lapse video from Namibia April/May 2022 is ready and posted to Youtube. Full HD, due to the size limitation not available at Vimeo. Enjoy!

For the gear heads: I switched from Canon EOS to Sony Alpha for the night sky time-lapses. The combination A7 III + FE 14 mm F1.8 GM is really a game changer for me.
