Herschel

Move your mouse over the picture to see the names of some of the features.  Click here to see a mosaic of six pictures of this area.

Herschel is a relatively recent crater at 'only' about 2,000 million years, but that is much younger than Ptolemaeus on whose northern walls it sits.  It is 43 Km in diameter and its walls rise to 3770 metres above its floor.  On the other hand, Flammarion is an ancient crater (around 4,000 million years old) and has been flooded by lava from Sinus Medii to its north.  This accounts for its smooth floor which is peppered with tiny craters which must be more recent than the flooding event. In the centre of this picture, between Herschel N and Reaumur A, is a valley which appears dramatically in this picture but, as far as I can ascertain, it has no name. 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.
