Far-side of the moon? I wonder how edited this image is?
Any photography buffs able to shed any light or have other images of the farside of the moon?
The WAC has filters, in the visible, or 'white light' range. However, there are many materials on the surface whos atoms emit 'light' at visible
wavelengths when irradiated with UV or X-ray energies from the Sun. The filters have a 'bandwidth', a narrow bandwidth will only let the light from
one targeted wavelength through, and then the ultra-sensitive image sensors amplify the hell out of that signal and feed it to the processing
electronics. The light level is so low that if you were out where the camera was, you would see nothing. All earlier attempts to image the far side of
the Moon with the very best cameras and fastest lenses failed miserably, and the announcement that they were to send a 3 tube Westinghouse colour
video camera with an f/0.7 lens to take images of the far side was quietly let drop from the news, as the camera saw nothing.
All previous farside 'images' were constructed from UV and IR specroscopic images and a laser altimeter. Any combination of 3 wavelenghts, say 2 IR
and one UV, is classed now as a 'colour' image, even though you can not see IR or UV light. NASA has never given us straight answers, why would
anyone think they have turned a new leaf? When NASA says images, it is a very loose use of the word.
