Altai Scarp to Crater Riccius
      #6451689 - 04/06/14 09:23 PM Attachment (22 downloads)

Always an eye catching feature when visible, the Altai scarp which is as tall as 4 km. was nicely reflecting sunlight on this evening. This scarp is the southwestern rim of the Nectarius basin and its fourth ring. The other features that caught my attention are the 3 old battered craters along the terminator: Zagut (84 km.), Rabbi Levi (81 km.) and Riccius (71 km.). The two younger, deeper craters between Rabbi Levi and Altai scarp are Lindenau (53 km.) and Rothmann (42 km.). All of these craters would go unnoticed at higher sun but low sun angles have a way of making them look good.

Sketching and Equipment:

For this sketch, I used black Strathmore 400 Artagain paper 9” x 12”, white and
black Conte’ pastel pencils and blending stumps.
Telesccope: 13.1 inch f/6 Dobsonian and 6 mm eyepiece (333x) riding on an equatorial platform

Wow Frank, incredibly detailed sketch of this southern highlands area just below the Altai Scarp and Mare Nectaris! A wonderful capture of this very busy area of the Moon.

Very nice intricate piece Frank. Interestingly the rendering seems to float above the deep grey background. Well done!
