 Taken under favorable seeing conditions, this image highlights in its very center the spectacular crater Tycho, the center of a vast bright ray system extending for thousands of miles across the lunar landscape. This 52 mile diameter crater has a stunning central peak, nearly a mile in height. Note the huge numbers of tiny craterlets around the periphery of Tyco. This is essentially the spatter from the original impact as the material was blasted at high speed in all directions.

Just to the upper left is the large crater Maginus, and the large flat floored crater to the upper right is Longomontanus.
