R1: Pitatus on southern border of Mare Nubium. Very irregular and poorly defined rim due to fractures and impacts. Large central peak is off-centre. Walls in the northwest are particularly eroded.
C1: Could easily see Rimae Pitatus along the NE and East side close to the rim. Also saw a bit of the Rimae in the NW. Could see some approaching the off-centre peaks but most was seen just inside the crater wall on the floor. The eastern floor was just a bit darker than the western floor.
Note: I was pretty excited to have the dark line going almost all the way from the crater wall to the off-centre peak confirmed after sketching. I was prepared to erase it if indeed I was imagining the dark line that may be a rille.
