Note on Distance

Copernicus 1 through 4 are from Lunar Orbiter 2 H-162; Spacecraft Altitude 45.9 above the surface. The camera tilt 69°20’... This means that effectively the distance from the lens to the object is roughly 138 kilometers. On Earth, such a distance would not allow for a lot of minute detail, however on the Moon that is a different story. Since there is very little atmosphere on the Moon there is little interference with a reflected light ray. There is no deflection, diffusion or dilution of any light coming off the object and hitting the camera lens. Proof of this is the amazing detail of the Hubble Space telescope images of objects billions of light years from Earth. Same rule applies... light in a vacuum travels forever until blocked or bent by magnetic fields.

What this means for us is that seeing small detailed anomalies should not be a problem. The fact that some areas do show a little "fuzziness" is further evidence that there is a least a slight atmosphere on the Moon
