Crater Cichus and Environs

Crater Cichus (41 km.) sits on the remains of the high rim of Mare Nubium in one of the few places where the edge of this mare is clearly visible. Resting high on the rim of Cichus is small crater Cichus C (11 km.). This region is a very interesting piece of lunar real estate which includes craters young, old, concentric ringed, buried ghosts, grabens like the one in this sketch to the north called Rima Hesiodus and domes like Kies Pi just beyond the sketch area. To the west of crater Cichus is a portion of Palus Epidemiarum.
The seeing was slightly less than average but you could wait for intervals of better seeing which arrived now and again.
A fun observation and relaxing sketch with mosquito repellent applied.
