Public Night at Chamberlin Observatory (Reservations Required)

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

*Tickets are required.

Please purchase tickets well in advance HERE, as we have limited space and sell out months in advance. On the reservations page, if you navigate forward month-by-month, you will eventually find dates that are highlighted in green, and those dates are available. There is no waiting list.
