What really dark skies are like

The sky was perfect for observing last night here in Wintergreen
Virginia. The comparison with the skies of Washington DC is
startling: instead of perhaps 20-40 stars visible (Washington) you
can see perhaps 6000 with the naked eye up here. Through my telescope
I got an incredible view of the Andromeda Galaxy: millions upon
millions of stars.

Tomorrow, Columbus Day, there are no classes for Mason's
students….but it's a regular work day for the administration. So be
it. I have a pile of work waiting for me when I get back.
