Clouds/haze around dusk and limited transparency, but Leonard was bright enough to deliver approx. half an hour of usable data for this animation of the movements within the comet’s tail (22 RGB frames).

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.
