Arzachel 18.2°S, 1.9°W

Arzachel is younger than Ptolomaeus and Alphonsus. It has a diameter of 96 km. When near the terminator it is an observational highlight for any size of instrument. The inner crater walls are markedly terraced, with a sharp-edged structure, and the long, slightly eccentrically placed central peaks reach 1.5 km above the crater's floor. Many craterlets and the 10-km crater Arzachel A lie on the floor. Arzachel also has a rille system, Rimae Arzachel. The main rille has a length of about 50 km, is significantly wider than the rilles in Alphonsus and follows the curvature of the eastern inner crater wall.

Alpetragius 16.0°S, 4.5°W

Alpetragius is a remarkable looking, circular crater, 39 km in diameter. For its size, it is unusually deep. Its central peak is conical in shape, and is conspicuously large when compared with the crater's diameter. In all probability, the central peak created by the impact was subsequently modified and enlarged through volcanism. Many craters in the vicinity show these broad, conical and unusually large central peaks.

Alphonsus 13.4°S, 2.8°W

Alphonsus is undoubtedly one of the most interesting craters on the nearside of the Moon. On old Moon maps it was described as a ring mountain. The prominent peak of the central mountain is visible, slightly north of the centre of the crater. A distinctive rille system, Rimae Alphonsus, lies on the eastern crater floor.
