IWLOP #066 - Albategnius

R1: Albategnius is adjacent to Ptolemaeus and Alphonsus. It has a central peak slightly off-centre. The eastern wall has numerous oval craters. Floor is relatively smooth. The scar on the east wall looks like a valley that ends in two craters.
R2: Klein is a circular crater that impacted the SW wall of Albategnius. Small central peak plus craters on it NE and SW rims. The SW rim has more impact craters. It also appears to be deeper than Albategnius. 

C1: The saucer-like depression on the floor of Albategnius was near the middle of the crater, with the central peak appearing to be on one of the edges of the saucer. There was a slightly darker colour in the saucer.
