Deep Craters On the Moon

Deep Craters Cover the Surface of the Moon as Viewed from the Table Mountain Observatory

This picture was taken on April 30, 1963 using the 16-inch cassegrain reflector telescope operating
at f/20. High Speek Ektachrome, ASA 100, was used by Charles F. Capen, in this 1/2 second
exposure at 0522 UT using a Miranda 35mm camera body.

With north at the top in this view, the ring-plain Abulfeda is seen at the extreme top center, some
40 miles in diameter. The walls rise nearly 2 miles above the central floor. A third of the way down,
just to the right center is the great lunar rings, Sacrobosco, with walls that exceed 12000 feet high.
Two thirds the distance from the top of the photo, is the crater Gemma Frisius, some 80 miles in
diameter. At the bottom of the picture is the large crater, Maurolycus, some 115 miles in diameter.

Table Mountain Observatory, operated by the Jet Propulsion Laboratory (JPL), is located just west of the
town of Wrightwood, California at an elevation of 7500 feet.
