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

NGC 6888 – Crescent Nebula – Ha
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.

NGC 7000 Ha Test
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.

M81 Bode’s and M82 Cigar Galaxies
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.
IC 410 – Tadpole Nebula
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.

Hakos und die IAS Sternwarte auf dem Farmgelände, mit Sicht auf den Gamsberg, waren wie die Jahre zuvor das “Basislager” für die Namibiareise. Leider im Jahr 2018 zur Marsopposition mit ziemlich schlechtem Wetter, auch nach der Rückkehr vom Gamsberg. Astrofotografisch relativ wenig Ausbeute, die schon vor einiger Zeit hier, hier, hier und in weiteren Einträgen gepostet wurde.
NGC 281 – Pacman Nebula Reloaded
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.
See also Astrobin for all details.

Trotz widriger Wetterbedingungen waren die sechs Nächte auf dem Gamsberg der Höhepunkt der Namibia-Reise, ein wenig “Star Party” Feeling auf 2340 m, die nächste Farm zwei Stunden entfernt, bei schwierigster Auf- und Abfahrt. Alle Bilder hier im Album Gamsberg.
Despite the cold and rainy weather, the six nights on the Gamsberg were the climax of our Namibia tour in 2018, a bit of “star party” feeling on 2340 m, two hours to the next farm, via a most difficult pad. All images here in the corresponding Gamsberg album.
