Yesterday night, 2009-09-04, I took some videos at Grimaldi crater in the Moon. I could visually spot a long shadow reaching the limb, and I don't know where it comes from, or which peak is casting it. Here it is a set of two pictures taken this night through my 6-inch telescope. One was taken using a webcam, and the other using a point-and-shoot camera.
