I agree with the post that the highlighting would be useful.  However, I believe that one of the eyes is improperly referred to.  At the top of the article, it states that "the figure's eyes are the Mare Imbrium and Mare Serenitatis".  But in the diagram with the four pictures of the moon, the two eyes circled are Mare Imbrium and Mare Tranquillitatis (for reference, see http://media.skytonight.com/documents/GettingStartedNorth.pdf)
