East side of Mare Imbrium

Captured on the same night I obtained this detailed mosaic of the terminator of the waning half-moon. There are too many incredible features to mention in this partial image of the most dramatic feature of the moon, which is an early, lava-filled impact basin. But....it extends from crater Plato in the north, to Rima Hyginus in the south. A three-image mosaic from full-frame videos (each image a stack of about 110 video frames, the best 15% of each video).
