This sketch is centered on the large walled plain crater Albategnius (135 km.). The well illuminated inner and outer rim margins appeared very rugged in contrast to the smooth floor interrupted by the off center mountain casting a large shadow. A sizable portion of the western wall was destroyed by crater Klein (45 km.). Klein also has a central peak which was overtaken by shadow during this observing session. Also visible in the sketch on the eastern side of Albategnius are craters Ritchey (25 km.), Hind (30 km.) and close by Halley (36 km.)


For this sketch I used: black Strathmore 400 Artagain paper, 8”x 12”, white and black Conte’pastel pencils, flat white paint, pink pearl eraser and blending stumps.
