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.
