    I was way off. The combined light from all stars down to magnitude 6 (visible limit for naked eye under ideal conditions) is about half that of the full moon. The combined light from the empty sky (from airglow, zodiacal light, and stellar scattering) is about 1/8000 of the full Moon.

      If so, I'm going to recommend to the community that we chip in and buy one of these for MB for his birthday or something. If he ever retires, it would be far better than a gold watch. What do you care what time it is after you retire?

          And God said, "Let there be light"; and with a Big Bang, there was light. And God said "Ow! Ow My eyes!" and in a flash God separated light from darkness. "Whew! Now that's better. Now where was I. Oh yea . . ."
