The moon in UV

Summary

edit
Description
English: Moon in ultraviolet using Kodak IIA-0 Spectroscopic film and Zeiss UV Sonnar 105 mm lens.
This photo is used in Figure 17-7 of the Apollo 16 Preliminary Science Report (NASA SP-315), which has the following caption:
The Moon at 305 nm (3050 Å): f/4.3, 1/60: TEC.

The Report discusses the figure as follows:

The appearance of the Moon at effective wavelengths of 305 nm (3050 Å) and 460 nm (4600 Å) is illustrated i n figures 17-7 and 17-8, respectively. Once again, there is little apparent difference between images obtained at these two wavelengths, certainly nothing as dramatic as the loss of contrast that occurs on Mars (fig. 17-1). The hypothesis that contrast will disappear at short wavelengths rests on the idea that the difference in appearance of dark and light areas is caused by different translucencies in the particles making up the maria and the terrae. A t sufficiently short wavelengths, absorption becomes complete, and only externally scattered light is visible (ref. 17-3). Possibly, short enough wavelengths for the effect to become apparent simply have not been reached, or perhaps some modifications in this interpretation of the observations are required.
