On May 21st, 2026, the clear skies offered me another successful photography of the International Space Station (ISS) transit in front of the Moon. Taken from Tuněchody, Czech Republic, as a sequence on a 10-inch Dobsonian Telescope, when ISS was about 722 km far from me and the whole transit took less than 1 second. It was the the most beautiful transit of ISS I ever photographed! Used Nikon Z6III, 10″ Dobsonian Telescope Flextube, ISO 2500, sequence of 1/2500s.
