Squares 2
Runde zwei der “Squares” findet sich hier in der Galerie, auch als Fotobuch in der Produktion.
More H-alpha
A completely clear night – not that many of them lately – provided several hours of H-alpha to catch the nebulosities above. Meanwhile I switched from the Optolong LRGBSHO filter set to the new Baader CMOS-optimized filters. At least H-alpha seems to work better in the combination with the Esprit 100 ED and QHY 268M, but still some problems with the flats.
See Astrobin here and here for details.

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.

NGC 7822 Loop in BW
Black and white (Ha) version of the previously posted image, the northern “loop” part of the NGC 7822 complex (Skysafari catalogs this one alone as NGC 7822).
