South is up in this image, more info below.
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.
