This is a close crop of the full size image. You can see the full size which includes the entire waning crescent moon as well as a detailed write-up on how these sorts of images are done on my website. I'd love to see if you try to get a shot like this yourself after reading my guide!

I had been planning to capture this shot for nearly a month. I use a ISS tracking website (transit-finder) to check to see if the station intersects the sun or moon anywhere near me, and this one showed up originally as a 45 minute drive from my house. Unfortunately, the station ended up doing a burn a few days ago which changed its telemetry, and ended up putting the path of the transit over a hundred miles away. I decided to proceed anyway, even though it meant preventing me from getting any sleep since the transit happened at 5am. Thankfully the conditions were good and the shot ended up being wonderful.

This was captured with a c11 telescope, and I used two cameras to capture it. an asi174mm and a sony a7ii (for the color on the moon's surface). The camera I used operated at 155 images per second to capture the station, and it was only in the field of view for about a quarter second.

Your work is incredible.

Dang that's cool but I sure hope you never have that camera pointed at my house lol
