 One of the brightest features on the near side was formed during the final intense bombardment of the moon billions of years ago. Copernicus is nearly as white as an impact structure can be, and from it emanates a system of linear rays from the ejecta spread. Of special note, to the left of Copernicus, small elongated secondary impact features are visible, created by material ejected during the original impact. Also on the left side is the large ghost crater Stadius, nearly buried to the rim by lava flows. The mountain range to the lower right of Copernicus is Montes Carpatus and just above is the strange double crater Fauth. You can see a prime focus "wide field" image here.
