Official FB page of the Dearborn Telescope at Northwestern University
Part of Northwestern University's Physics and Astronomy Department, the Dearborn Observatory houses what was at one time the largest refracting telescope in the world (having 18.5-inch Alvan Clark optics).
Nearly every Friday evening, the Dearborn is open to the public for free viewing sessions with the historic telescope. Visit http://www.physics.northwestern.edu/observatory/ for more information.
