Casatus and Klaproth Home

Move your mouse over the picture to see the names of the various features.

Casatus is 114 Km in diameter and 3900 metres deep.  It forms a nice double with Klaproth, 122 km in diameter and 4300 metres deep.  They are both about 4,000 million years old.   These formations are close to the south pole but the libration was particularly favourable, at 6°, at the time I took this picture.  This has brought Drygalski into view.  This large crater, 170 Km in diameter, is at 80° South latitude which puts it only about 300 Km from the south pole.
The scale marks in the bottom left-hand corner indicate approximately 50 Km north and east.
The picture was taken using my LX200 with a X2 adaptor lens on 7th October 2004 at 04:08 UT when the Moon was 22.8 days old.
