Public Night


Showing the Night Sky or the Sun to Others

There is a wide range of volunteer opportunities involving astronomical observing for DAS Members, including bi-weekly Public Nights at DU’s Historical Observatory, monthly Open Houses at Chamberlin, and Public or Private Star Party/Astronomy Outreach Events. Sharing our knowledge and love of astronomy is one of the most important things we do.

Star Parties/Public Observing

The DAS provides telescope operators, lecturers, and experienced sky guides for astronomical activities at schools, businesses, nature centers, and conferences.

DAS MEMBERS: We are in need of volunteers. Please email July Candia at external@denverastro.org if you can assist. Thank you!

DAS members who want to volunteer to operate the 20-inch Clark-Saëgmuller telescope for Public Nights in DU’s Historic Chamberlin Observatory may do so by entering the Operator training program. Please contact the Public Night coordinator, Hugh Davidson, at 303-679-0629 for information.

Open Houses

Open Houses are a fun activity both for the public visitors and for DAS members. It can be a real blast showing visitors the sky. Many have never looked through a telescope before or have seen a planet or even the Moon close up.  They’re a great way for new members to get a taste of the joys of astronomy outreach.  Just bring your telescope to Chamberlin Observatory on an Open House Night, set it up, and enjoy the experience.  If you’re new to astronomy, visit an Open House and kibitz while more experienced outreachers interact with the public to get some tips.
