This is an eyepiece projection shot of the lunar dogleg formed by the prominent craters Theophilus, Cyrillus, and Catharina that I took at the Astronomical Society of Harrisburg's Naylor Observatory near Lewisberry, Pennsylvania, using a 17" f/15 classical Cassegrain and a Pentax K1000 SLR camera.  Each of the craters is on the order of 100 kilometers in diameter.  Theophilus is the uppermost crater and lunar north is up in the photograph.
