Region of crater Albategnius
Captured on the same night I obtained this detailed mosaic of the terminator of the waning half-moon. This beautiful crater is in a spectacularly rugged region southeast of Mare Imbrium. The diagonal grooves apparently formed when low-angle ejecta, blasted out by the impact which caused formation of the mare, ripped through the moon's surface. The video was obtained with a small chip area (1600x1200 pixels) to increase the number of frames to 3,000. The best 5% of these were stacked to create the image.
