The lunar crater Ptolemaeus at sunrise.  I can almost imagine myself standing on the crater floor viewing up at the castle-shaped crags on the rim.

 

The most prominent floor crater Ammonius is not visible, being completely covered in shadow.

Super, John...I love your use of 'crags' -- they evoke memories of the Scotland terrain during a geologic trip, where, in the end, we settled down comfortably in the local 'crag' pub  lol.gif at base.

 

If anything we should learn from your image is the 'convex' (doming upwards like) nature of its floor -- note, the shadow effects.
