This region of the Moon from the southeast edge of the Mare Nubium I find interesting because of the relief.

Rupes Recta is a straight wall 110 km. in lenght and is 240 meters high on the Mare Nubium. This is a favorite area on the Moon for amateur astronomers.
Isolated crater Birt (17 km), is on the right of Rupes Recta also on Mare Nubium, and has a depth of 3.5 km.Birt is shaped bowl and is intersected with the edge of the smaller crater Birt A (7 km).
I've posted photos of Thebit crater (57 km), but it was in sunlight and not have seen some features. Here you can see better the crater floor which has no central peak.The depth of Thebit is 3.3 km.
Purbach (118 km), is part of a trio of craters with Walther (128 km) and Regiomontanus (110 km) aligned from south to north, and Purbach is the northernmost.
