Time lapse #astrophotography of sunrise over Montes Caucasus on last night's first quarter #Moon. Covers 4 hours of real time. 79 x 1500 x 35 ms Ha 35 nm in Celestron 8" + 2.5x powermate.
Closeup view of jagged terrain at the lunar terminator. The peaks of Montes Caucasus throw long shadows that initially extend into the terminator but shorten drastically over the course of the animation. Also as the animation loops the moon appears to shrink a tiny bit this is due to a change of distance as the observer rotates on Earth.
