A few brighter stars upon a field of dimmer ones. There is a set of stars that looks suspiciously like a double, and another that looks like it could be a triple.

Waited an hour or so for the moon to rise higher and lessen the turbulence. I spent twice as long on this sketch trying to get as many details in as I could.

Palus Somni is the lighter region. Mare Tranquilitatis is the flatland to the west and Mare Crisium is behind the ridgeline and terminator to the east. Proclus is the smaller crater almost dead center in the sketch (it has a tiny crater just north of it.
