A 27-frame composite of the ISS transit in front of the moon at 80% illumination. As a bonus I managed to capture the transit of a smaller satellite simultaneously just below it - a fun surprise! This shot has been on my photography bucket list for a while, and, for a first attempt, I'm really pleased how it turned out.
