Alas, the setup had to be done in a hurry with many problems and the Epsilon is badly collimated at this point in time. A planned maintenance trip now most likely faces travel restrictions.
So please bear with the image quality, especially on the left side. ;-)

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.

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.

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.
