If you’re at the right place at the right time, with the right equipment, this is possible.

Last night, with guidance from https://transit-finder.com/, I positioned myself along the narrow line where the International #SpaceStation would pass between me and the nearly full moon.

I used a Fujifilm X-T4 shooting 4K video through a Celestron 8” SCT to capture the pass. Then, back at the computer this morning, put together these views with PIPP, Registax, and GIMP.

Quite pleased. My best yet.

International Space Station Transit Finder

This website helps plan observations of the International Space Station transit events in front of the Moon and Sun.

@BeckePhysics

Very nice. Is the background moon picture just from the transit or also uses extra imagery?

@knud I took an additional 106 video frames before/after the transit and stacked them as the base image. Then edited the ISS frames on top.

@BeckePhysics @knud

so skepticism justified?

I'm still not sure what I'm looking at…

You're looking at a composite image of the ISS moving across the moon's face, observed at video speed, and the stationary moon behind it. Total sequence is probably half a second of video.

@knud @irtapil Here’s the original video clip (to remove the skepticism), then slowed down to see the individual frames, then what post processing can reveal. So nothing added, just enhancing what’s already there.

Wow! The ISS is travelling so very fast, but I often think of it lazily floating in orbit. Thanks for sharing the video.

@jpk @BeckePhysics only 90 minutes to go round the earth. pretty fast.
