COMMENTS:
The fully eclipsed Moon as it appeared about 11 minutes after it entered the umbra, the darkest portion of the Earth's shadow. 
According to Rayleigh scattering, the red glow of a Total Lunar Eclipse arises because sunlight reaching the Moon must pass through a long and dense layer of the Earth's atmosphere.  Shorter wavelengths are more likely to be scattered by the small particles, and so by the time the light has passed through the atmosphere, the longer wavelengths dominate.   Perhaps a tad complicated, but it sure is pretty!
