ISS transit across the Moon.

I usually spend hours collecting light for a single image. This time it’s the opposite: three days of preparation for just 0.89 seconds of shooting — that’s how long the station takes to cross the lunar disk.

You can’t shoot this from just anywhere: you have to travel far from home and find a spot within a narrow path only a few hundred meters wide, so the trajectory passes as close to the center of the disk as possible.

Somewhere nearby, a tavern is blasting 90s disco, while we’re staring at our screens, waiting for that moment — a brief black silhouette after which it becomes clear: it was all worth it.

Raw Data

Not a typical package. This archive contains a raw video of the ISS transit (may be processed in Siril) and a number of light frames for the background, without calibration.
