Ptolemaeus (top), Alphonsus and Arzachel form an eyecatching triplet of craters. Rupes Recta (The Straight Wall) further south is also one of the more interesting features in this area. It is not a steep wall at all but a gentle 7° slope. During the waning phases it shows up as a bright feature

High resolution image of Ptolemaeus. Seeing was poor but I just wanted to test the new webcam at high magnification
