L93: Dionysius dark rays

Dionysius was formed at the border between the darker mare and the brighter basin ejecta. The jumble of bright and dark rays seen around the crater was created at the impact, and is a mix of the different materials. At the eyepiece the rays were quite obvious, but difficult to capture in the sketch. To the east (left) a beautiful pair of low rim craters, Sabine and Ritter.

Sketch made on 26 April 2015 using a SkyWatcher 10″ and a TeleVue zoom 3-6 (mostly at 6 mm).
