This high resolution photograph shows fantastic detail of the floor of Crater Copernicus was taken with the 610mm telephoto lens from an altitude of 103 km. Latitude 9.52° N, longitude 20.70° W.
Copernicus is a 93-km wide and 3.8 km deep lunar impact crater located in the eastern Ocean of Storms, named after the astronomer Nicolaus Copernicus. The central peaks consist of three isolated mountainous rises climbing as high as 1.2 km above the floor. These peaks are separated from each other by valleys, and they form a rough line along an east-west axis.
Before Apollo, the United States flew five Lunar Orbiter robotic satellites around the moon taking analog photos in strips. The film had to be developed inside the satellite in the onboard dark room (since the satellite would not return to Earth). The film was then raster scanned with a 5-micron beam and transmitted back to Earth. This high resolution image is an aggregate of many strips. A lot of work before digital cameras!
This extraordinary detailed large format original photograph was not released to the public. In every NASA press release, they showed a degraded photo of a photo. It was the Cold War period, and the U.S. did not want the Soviets to know how good our spy sat camera resolution really was.
