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.
Technical details at Astrobin.

Continuing the explorations with the QHY268M, a two panel H-alpha mosaic. And the first time I used NINA to control the imaging session.

Partial (Annular) Solar Eclipse 10 Jun 2021
Lacking the joys of eclipse chasing, at least a partial solar eclipse at home (annular in North America).
Turkey 2006 – Kilistra, Çatalhöyük, Mevlâna Museum Konya
Finally completed the album with images from the trip to Anatolia, Turkey for the total solar eclipse on 29 Mar 2006, somewhat in time for the 15th anniversary.
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.
More details at Astrobin.

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.
