One of the very few oblique views showing the lunar horizon taken by the Lunar Orbiter spacecraft.
The low altitude of only 58.98 km of the spacecraft, high oblique view and the low Sun elevation near the terminator emphasize details of the relief in this breathtaking photograph taken with the wide angle 80mm lens looking southwest toward the southwest rim of the Ocean of Storms including Crater Damoiseau (latitude: 3.33°S; longitude: 59.78°W).

"The moderate-resolution photograph on this page was taken by Lunar Orbiter III on February 22, 1967, at an altitude of 35 miles, near the point 1° N, 58° W, in the southern part of Oceanus Procellarum, looking generally southwestward.
This particular photograph was taken to determine whether the innermost crater, Damoiseau, of the large, double-walled crater at right center is a collapsed volcanic structure, as it appears to be from Earth-based telescopic observations. According to scientists of the U.S. Geological Survey, this oblique photo alone is not conclusive. However, a careful review of another Orbiter III photograph of the same area, a vertical view, indicates that the inner crater is indeed a collapsed volcanic crater and the outer wall the remnant of an older, impact crater.
Another interesting aspect of this photograph is the contact between the marelike material in the foreground and the steep, semicircular cliff at its far edge. This headland has extremely steep sides, yet there is very little evidence of slumping at the base. This suggests that the mare material has flooded an old crater, its near rim already worn away by meteorite impact or submerged in general tilting."
