Sometimes when observing the Moon you may see some objects transiting its surface…
Sometimes these objects are rather large…and illuminated, so one can actually see it approaching the Moon without any telescope…
This was the case with this event, both myself and my wife observing the ISS rising and moving faster and faster towards the Moon…What a fantastic event!
Th above animation was acquired with a modified 200mm F/5 Newtonian and ASI 174MM camera. The transit was predicted via CalSky website.
