International Space Station Lunar Transit

I caught the International Space Station transiting the moon in the daylight hours. It flashes through the frame in under a second! Want to catch a transit? Use the ISS Transit Finder website to plot your encounter.

Equipment: Celestron C11 on a CGX mount, f6.3 focal reducer, Nikon D5300.
