Features of Rachmaninoff Cratrer (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)

Rachmaninoff is a spectacular Double-Ring Impact Basin on Mercury, and this Absolute Natural Color view of it, is one of the highest resolution color image sets acquired of the Basin's Floor. Visible around the edges of the frame is a circle of Mountains that make up Rachmaninoff's Peak-Ring Structure, which surrounds concentric Troughs located on the on the Basin Floor. The color of the Basin's Floor inside the Peak-Ring differs from the darker material outside of it, as can also be seen in other images of this Feature.
