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.
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.
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!
