On Wednesday, February 23, 2022, during its testing on the grounds of the observatory at the Astronomical Institute of the Czech Academy of Sciences in Ondřejov, one of the two SST-1M Cherenkov telescopes recorded its first events initiated by high-energy particles of both the hadronic origin and originating from gamma-ray photons.

The SST-1M (Single-mirror Small-sized Telescope) detect high-energy gamma-rays from cosmic sources in our Galaxy or in the extragalactic space. Two SST-1M telescopes have been built at the Ondřejov Observatory since 2021. They were originally conceived as prototypes for the entire class of small-sized telescopes for the Cherenkov Telescope Array (CTA) project. Two telescopes will for the first time start to take data together in the stereoscopic mode. Recent data have been recorded in several celestial directions, including the surroundings of the famous Crab Nebula.
The SST-1M team is composed of members from multiple institutions in Poland, Czech Republic, Switzerland, and Ukraine. It is led by the University of Geneva. Jagiellonian University and AGH University of Science and Technology in Kraków developed and contributed to manufacturing the fully digital electronics for the camera, that digitizes the photon signals from all camera pixels despite their short duration of a few nanoseconds. A the Jagiellonian University the project is realized in Astronomical Observatory. Here, in the CTA Electronic Laboratory Eng. Krzysztof Ziętara is co-leading current efforts on optimization of the camera operation, while research program for the SST-1M project is partly elaborated in the Department of High Energy Astrophysics.
