After hours of planning and a good stroke of cosmic luck, I present the International Space Station ⁠#ISS making a flyby of #Jupiter! You can even see the Galilean moons. Lost for words with how this turned out - I hope you like it just as much as I do! 1/4 Image @astro_Pettit @Space_Station @NASA_Astronauts @esaspaceflight @dominickmatthew Here is a composite version with the brightness difference neutralised. Gear used was the Sky-Watcher 400P (16" Dobsonian), and Uranus-C camera at 4700mm f/11.5. 1.2 millisecond exposures in 4K ~47fps. 2/4 Image
