Public Nights and Open Houses

Public nights at the Chamberlin Observatory began in 1894. Hosted by the Denver Astronomical Society, public nights take place throughout the year. Attendees must register ahead as there are limited seats on each night.

Registrations are made through the Denver Astronomical Society website, which also has additional information on available dates and pricing. DAS also hosts monthly open houses with small telescopes on the lawn. These are free and no registration is required.
