Ptolemaeus, Alphonsus and Arzachel

The three large craters, from left to right, are: Ptolemaeus (158 km) Alphonsus (108 km) and Arzachel (96 km).

The smaller crater at left is Herschel (40 km) and at lower right Alpetragius (39 km) the latter notable for its larger-than-usual central massif.

Below, a wider shot of the area (with a lower sun angle) this time including the crater Albategnius (114 km) at top.

See Lunar Craters for more detailed views of Albategnius, Ptolemaeus, Alphonsus and Arzachel.
