A snapshot of the U.S. Naval Observatory

DCist provides an interesting peek inside the USNO.  Blogger Heather Goss documents a recent tour, from the 12" Alvin Clark refracting telescope that was built in 1892, to original works by Tycho Brahe, to the clock room where you see every piece of timing equipment used throughout history (except for the current operational hydrogen masers).  I have never been on this tour, but it is now on my list.  The USNO web site has information about tours and events.
