ISS

During the spring, 10,000 frames were captured, of which 1,000 contain the ISS, with 40 successful frames in more or less normal atmospheric conditions, and 20 stacked from them. The atmosphere was 3 out of 10, unfortunately. The distance to the ISS at culmination was 574 km, and its altitude above the horizon was 46 degrees. I shot with a friend; he was at the laptop announcing when the ISS entered the frame and monitored its brightness, while I tracked the target through an illuminated finderscope. We also tested a camera that had just arrived with a global shutter.
