Backyard Late Summer Nighttime Sky Over New Jersey.

Last night the sky was clear, and the waxing gibbous moon (61%) bright, so I set up a couple of cameras with big lenses out on the deck. One of the systems (Nikon D4 camera TC-E III 20 teleconverter and 600 mm f/4 VR lens (ISO 400, 1200 mm, f/8, 1/60 sec)) was set to record video (1080p, 30 fps). While reviewing the videos I noticed one with something (a bird?) passing in front of the moon. Played back at 10 fps shows the transit to occur over 25 frames.
