Messier A and Messier   Leave a comment

The changing appearance of Messier A and Messier (9km x 11km) in the eyepiece over the course of a lunar day produced a controversy that was not settled until the Lunar Orbiter and Apollo missions.  Here is a snapshot from Meshlab (with some extra contrast added in Photoshop) of the two craters modeled from the SLDEM dataset available at Map A Planet 2.

Messier A and Messier carved from Maple at 1:100,000 scale, fresh off the CNC and still fuzzy.  Sunlit for sharp shadows.
