   Colors of the seas

    
    



By Alain Paillou
  
 
Mare Nubium region on the Moon, showing the variety of colors of the soils.
 The picture was taken with a SCT 9.25" telescope, a mono camera for details and a color camera for colors.
 Colors come mainly from metallic oxides in the soils (blue for titanium, orange for iron or low titanium).
 We can see the complexity of sea structure, the difference with the crust (you can recognize Ptolemaeus crater) and the influence of the young craters (light blue, nearly white colour).
 This picture shows more clearly the geological history of the Moon, which is quite complex.
