Ptolemaeus & Rupes Recta - Ptolemaeus, Alphonsus, and Arzachel (from top to bottom) are the three large craters in the center of this photo. If you can't see them, try to look for the "upside-down snowman" which the three craters seem to make. To the right of Arzachel is the straight fault line, Rupes Recta, whose black shadow is readily seen.
