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.

The partial solar eclipse of 25 Oct 2022 over Cologne-Dellbrück, Germany. Partly cloudy skies provided a natural ND filter for these images. Alas, a complete cloud cover obscured maximum eclipse at 12:07 CEST with a magnitude of 0.33.

And yet another image from April/May at the IAS Observatory Hakos, Namibia. NGC 3621 is a field galaxy, i.e. lonely galaxy ;-), in the constellation of Hydra.

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.

Already done in 2019, here comes another shot at NGC 2997, a face-on unbarred spiral galaxy in Antlia. Only 1 hour of total exposure time due to many technical problems with the 20″ Cassegrain.

More southern sky galaxies from the trip to Hakos, Namibia in April/May 2022, the Meathook Galaxy NGC 2442 and the elliptical galaxy NGC 2434 plus some smaller PGCs.

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.
Continue readingA 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.
