Dark ring around Tycho

Last week I shot some images of the Tycho crater rays. You can see the ring of dark material around the bright crater-rim very clearly. The bright crater rays seem to start from this ring of dark material. The craters that are visible near the southern limb will be discussed in one of the next weblog entries. In the meantime, enjoy the view!
