Notes
Clear and warm night, with lots of low level atmospheric turbulence flickering the lights on the mainland. But high above the moon, waning gibbous poses an entrancing object. With the 10mm piece in and the Barlow, the terminator lies across a gorgeous quartet of craters north of Mare Crisium.

Starting at Cleomedes, which is all in shadow, there are three small craters to the southwest which I have no names for. Cleomedes is 129km x 129km and is neatly circular. Between Cleomedes and Burckhardt is small Burckhardt E and then Burckhardt itself, an irregularly shaped crater which is 60 x 60 kms and has a small mountain, the very tip of which was still in sunlight.

Moving north, we come to Geminus which is spectacular. Complex walls and a high mountain that cast a shadow right up the east wall of the crater. Geminus is deep, at 5400 meters, and it's mountain is tall. Messala, a lot further north and almost cut off in the darkness of the terminator is the last of this quartet.

To the east of these larger craters are a bunch of smaller ones. I sketched 14 or so tonight.
