What’s an astronomical sketcher to do at full moon? These are actually good times to catch rare details on the lunar limb, and here I have caught three of the valleys on the south-western limb of the moon close to the crater Inghirami, which in turn is just south-west of Schickard. These valleys are radial to the Orientale basin and created by the same impact. Vallis Inghirami is the easiest to spot by virtue of its proximity to the crater of the same name, whilst Bouvard is also striking by virtue of its greater elevation and length. Baade is harder to pick out because it’s behind Vallis Inghirami and mostly hidden behind its own rim. This dramatic landscape mirrors the cataclysmic event that must have created it about 3.5 billion years ago.

Excellent sketch of this vista and fine description of what is seen.
