First light from the new Berthelot Solar Observatory

We obtained full disk solar images of the photosphere (WL), Calcium II K line (Ca II K) and chromosphere (HA), for the first time remotely, controlling the instruments from Bucharest. Solar activity is near the maximum of the 25th cycle and we can see many active regions with many sunspots, plages, filaments and other interesting details of the solar photosphere and chromosphere. We use three Vixen SD102 refractors on an ASA DDM85 mount, a Baader Herschel Prism for WL, a Calcium line filter and a DayStar Quantum PE H alpha filter. Further work is needed to fine tune all equipment, developing a procedure for remote work and image processing pipeline.
