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.

Another single while wading thru the large amount of images and videos.
Another single image from the new eruptions on 11 Sep 2021, the most prominent lava fountain in the middle of the lava field in Geldingadalir.
A trip to Iceland in September, with high hopes to see the Fagradalsfjall volcano in action. At first a bit disappointed, because activities stopped just before we arrived, we were lucky on the last but one day and the fourth hike into the volcano area. A splendid display of lava fountains and flows from the late afternoon into the night. More images/videos to come!
