Because it’s that time of year … a fresh shot at a very familiar target during two clear nights in October. Ha, L, R, G, B with the QHY268M, but still facing problems with the Esprit and the Optolong filters.

Dank Thomas Winterers freundlicher Genehmigung, seine Daten vom August auf der IAS Sternwarte Hakos, Namibia für eine eigene Bearbeitung zu nutzen, kann ich dann auch wieder den König der Planeten fast zur Opposition (20.08.2021) mit den bis jetzt besten Details hier im Blog präsentieren.

Two more clear nights in August allowed for capturing OIII data for the NGC 6888 field, so here comes a bicolor processing.

Still a work in progress, mastering the QHY268M with the Optolong LRGBSHO filter set. Seems like a setup with reserved filters is required for the Esprit 100 ED with the original flattener, in order to avoid strange reflections from bright stars such as Deneb or Sadr. Shooting a familiar target here.

Continuing the explorations with the QHY268M, a two panel H-alpha mosaic. And the first time I used NINA to control the imaging session.
Backyard astrophotography in light-polluted Cologne-Dellbrück (SQM 19.7)
Skywatcher Esprit 100/550 ED, Skywatcher Flattener, Optolong Ha 7nm / QHY268M
OAG with Lodestar X2
Mount AZ EQ6 GT
Image acquisition: CdC, NINA, PHD2, dithering
Ha: 2 x 6 x 600s, mode 1, gain 56, offset 10, -5C, 10 flats, 50 bias, 20 darks
Data calibration/integration: PixInsight
Image processing: PixInsight, Lightroom, two panel mosaic
First steps into the realm of mono astrocams with the QHY268M. Pretty amazed what 3 x 10 min were able to pull out of my suburban skies.

The last one for this season, weather wasn’t that stellar for astrophotography in the last months, so too little exposure time and too much noise. To be continued in 2022 …

Auch 2019 war wieder Hakos, Namibia auf dem Programm, dieses Mal “nur” Astrourlaub pur mit reicher Ausbeute, da zwei Wochen lang “Schönwetterkatastrophe”, auch für Namibianische Verhältnisse. Die astrofotografischen Ergebnisse gibt’s schon länger im hier Blog, eine Zusammenfassung u.a. im Deep Sky Video 2017-2020. Ergänzend neu in der Galerie eine kleine Bildserie “drumherum” – Hakos Guest Farm, Rooisand Desert Ranch, Groot Gamsberg Farm.
Again, two months to gather enough photons for this image. The bulk of the exposures were taken during a spell of five clear, cold nights in Feb 2021, though. The emission nebula IC 410 also includes the open cluster NGC 1893.

A new approach to the Pacman Nebula with the L-eNhance filter and bicolor processing. No so much for clear skies in the winter season here, took over two months to gather some meagre 10 hours of exposure time.
