How dark is dark ?
Hi,
Years ago I had the pleasure of living in Tonga, a small island state in the Pacific ocean. At that time I had no interest in astronomy, but I do remember the night sky looked like someone had splashed paint across it, such was the density of stars. At times I, literally, could not see my hand in front of my face. Anyone here have an idea what sort of mag skys they may have been, and has anyone been anywhere darker ? Regards Andrew |

A good test is if you cannot see clouds when they pass through the sky. Regards Andrew -- I. N. Galidakis http://users.forthnet.gr/ath/jgal/ Eventually, _everything_ is understandable |

Is the 'Venus casts a shadow' thing a myth or true for dark skies?

It's no myth. I personally saw it during the 2004 Venus transit.
Venus was bright enough that a fuzzy shadow of the scope and my body could be seen with the naked eye at a dark sky in the Intermountain west. - Canopus56 |

"Gaz" asked:
Is the 'Venus casts a shadow' thing a myth or true for dark skies? From a not-very-svelte Patrick Moore, writing in his book _Venus_ (2002), p. 37: ... Venus can then cast perceptible shadows. I well remember that some years ago, when I was at the La Silla Observatory in the Atacama Desert of Chile, Venus was superb; I stood against a white wall, and my shadow was very obvious indeed. Mind you, I have to admit that I am rather good at casting shadows! -- ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Mark Gingrich San Leandro, California |
