On 21st of August 2022 was a special day. Around noon the international space station made the transit across the Sun. I was ready and managed to capture it. The transit itself took only 0.4 seconds and the frame rate of my camera was only 20 FPS, so I captured only 8 frames. In total, I captured 2000 frames, out of which I selected the best 75% and stacked them together. The ISS was added from the transit frames as separated layers.
And here is just the stack without ISS:
|Focal length||420 mm|
|Mount||Rainbow Astro RST 135|
|Camera||ZWO ASI 178MM|
|Exposure||2000x3.5ms, Gain 149, bin 1x1, 75% selected|
