Tour Mount Wilson Observatory and

View the Night Sky through the

Historic 60-inch Telescope

A Special Offering for PATS Participants

Mount Wilson Observatory is the birthplace of modern astronomy and astrophysics. No other research site on Earth has had the scientific impact that resulted from superbly talented astronomers having access to unparalled facilities in the first half of the Twentieth Century. During your Mount Wilson sojourn, you will
  • See up close the "real" Hubble Telescope - the Mount Wilson 100-inch,
  • Visit the Monastery, where every famous astronomer of the period took respite from the night's work,
  • See how solar astronomy continues from the Observatory today,
  • Tour the CHARA Array, the world's most powerful telescope for high angular resolution astronomy,
  • Enjoy supper on the mountain in an unforgettable setting,
  • Observe through the 60-inch Telescope.
The Mount Wilson 60-inch Telescope was the first truly modern telescope in its incorporation of silver-on-glass optics and a precision controlled mounting. The telescope entered into its second century of operation in December 2008, and is now regularly booked by groups for visual observations. Go here for more information about the 60-inch experience

In cooperation with the 2012 Pacific Area Telescope Show, the Observatory is offering PATS attendees the opportunity to tour Mount Wilson and observe through the 60-inch on an individual ticket basis. We have scheduled the nights of September 21 and 22, 2012, and tickets are sold on a first-come, first-served basis. Mount Wilson Observatory Superintendent Dave Jurasevich will personally conduct the tours and direct the observing sessions.
