Rupes Recta

Rupes Recta, or the Straight Wall, is a rille (a ridge or cliff) on the southeast shore of Mare Nubium.  This one takes a more powerful telescope to see well.  Visually it looks just like a straight pencil mark on the surface of the moon.

This image is out of focus...  I really need to shoot this again.
