This is the crater Petavius (177 km), on the far eastern side of the Moon's visible disc. The problem with Petavius lying so far east is that the Sun rises on it during day two or three of the lunation. Alternately, you can catch it when the Sun sets on it a day or two after full Moon, as I did last night. If you wait a bit into the evening, it'll be nice and high in the sky. The most striking features of Petavius are its central massif, rising 1.5 km above the crater floor, and its prominent rille, running southwest for 80 km to the crater rim. The rille is 2 km wide. You can also see that Petavius' floor is not flat, with smaller rilles crisscrossing the northern section. As well, Petavius has a broad rim, especially evident along it's southern half. The crater Wrottesley (58 km) abutts Petavius on its northwestern flank.
