Walter Home

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

Walter is an elliptical crater measuring 145 Km by 136 Km. It lies just south of Regiomontanus and is exactly on the Lunar meridian (longitude 0°).  Its floor is very rugged in the east but smoother in the west.  Aliacensis is 82 Km in diameter and 3700 metres deep.  Werner, to its north, is a much younger feature (between 1,000 and 3,000 million years), and is 4220 metres deep.  Purbach and Regiomontanus are shown in more detail elsewhere.
The scale markers are approximately 100 Km north and east.
The picture was taken with a ToUcam attached to my LX200 on 26th March 2007, when the Moon was 8.4 days old.

A view of the area slightly to the east of the picture above.  The Sun was somewhat higher in the lunar sky so it illuminates craters to the east of Walter, which is almost fully illuminated.
I have a mosaic of this picture and two to the south here
