Stefan,
You have captured one of the most curious lunar surface formations! (a small dark craterlet which was also photographed during the mission of Apollo 16).
It's the tiny dark spot southwest of the bright Lassell D craterlet.

This photo is fantastic! Ive seen similiar views taken during the Apollo 14 mission, but this one is better. You didnt happen to stowaway aboard spacecraft and took personal pictures did you? For it sure looks like it. Its one of the best Ive seen of this region.
