The Lunar crater, Ptolemaeus is the subject of the November 2009 Drawn to the Universe column. The focus is on creating a crater sketch along the rapidly changing terminator. In the tutorial, we use of 2H and HB pencils to shade the deep shadows and lighter surrounding terrain, while using vinyl and kneaded erasers to sculpt and touch up brighter areas.
