This image is a very recent release from the Lunar Reconnaissance Orbital Camera (LROC), taken 10 June 2011. The angle was 65 degrees in order to capture the sunrise on the peak in Tycho crater. The large boulder in the center is 120 meters across.
Tycho is located at 43.37°S, 348.68°E, and is ~82 kilometers (51 miles) in diameter. The central peak rises 2 kilometers above the floor of the crater. The floor is almost 5 km below the rim.
Below left is a view of the entire central peak, and below right is a view of the entire crater.
