The ISS Transits the Moon – 1st June 2020

The ISS (International Space Station) orbits the Earth every 90 minutes.  Very occasionally, wherever you are on Earth, it’ll pass between you and the moon.  On 1st June 2020, the ISS made a pass between me and the moon, and I decided to have a go at capturing it.  After finding out the exact time it was due via, I pointed my 102mm refractor Moonwards with a camera stuck in the back, and lo and behold, in a feat of mathematical amazingness, the ISS flashed across the face of the moon at the exact time, to the second, it was expected to.

The following was the result!  It was captured using an ASI224MC Planetary camera via a Starwave 102ED f/7 refractor.  The thing I love is the way the video gives you a fantastic sense of the sheer speed at which it’s moving…


A bit of processing to combine the frames in an application called StarStaX (, usually used for combining star trails shots, followed by wavelets sharpening in Registax, gave the following image…

ISS Lunar Transit

Very pleased with this result!  May possibly have a go at imaging the ISS at closer range at some point given the accuracy of the timing and positioning of this pass…
