Chamberlin Observatory Tours
The Denver Astronomical Society hosts weekly and monthly events* at the University of Denver’s historic Chamberlin Observatory, featuring its prized 1894 Alvan Clark-Saegmuller 20-inch refracting telescope. It serves as the DAS home base for numerous Public Nights, Open Houses, and special events throughout the year.
