Albategnius is further east than Ptolemaeus and Alphonsus and so the Sun was lower in the lunar sky here
than in my pictures of the latter craters taken at the same time. Consequently detail within the western side of
the crater is obscured by the shadow. This is particularly true of the smaller crater, Klein, whose western walls
are particularly high. Both craters date from about 3,900 million years ago although Klein must be the younger
of the two. Albategnius is 140 Km in diameter, and Klein is 46 Km in diameter and has walls reaching almost 1500 metres high.
Both craters have central mountains, but that in Klein is hidden by the shadows in this picture.
The picture was taken with a ToUcam attached to my LX200 with a X2 adaptor lens on 6th September 2004
when the Moon was 21.8 days old.
Some more pictures of the area around Albategnius can be found here.
