Chamberlin Observatory Tours

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 the DAS home base for numerous Astronomy Nights, Open Houses, and special events throughout the year.

Due to overwhelming demand, we are changing how we reserve our Astronomy Nights and adding more to the calendar. For details, see our Reservations page.

If you have any questions about EXISTING reservations or want to change your existing reservation, email us at reservations@denverastro.org.
