Mare Orientale is one of the most impressive features on the moon, a tremendous multi-ring imact basin. Unfortunately it is right on the limb where we earth-bound observers can't appreciate it.
I managed to get a few pictures of it last week when the moon was in favorable libration - over 6 degrees - and put them together into one large picture. Then I stretched it in a way to simulate a perspective above it: the picture on the right shows the central basin at the left edge, with the two rings extending toward the right. Some dark lava can be seen filling the area between two of the rings at the bottom left.
