Yesterday morning I captured a moment that lasted less than a second- the ISS in front of our moon.

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.

If you want to see the full image (this is a close crop) I just posted it to my twitter with the same handle (ajamesmccarthy) and website where I've also done a more thorough writeup describing how you can attempt these shots yourself!
