Open houses are only held when the skies are clear. If you're not sure if we'll be open, check out our local weather or call us for an observing status at 303.492.2020.

There is no charge for the Observatory's Open House nights ... the stars are free to everyone! Sessions typically last from 1-3 hours, depending upon the weather, the quality of the night.

Currently, UNAVAILABLE due to ongoing concerns related to COVID-19.

Normally, our free open houses are held on Friday evenings at 8:00 p.m. when CU classes are in session (during the spring, summer A & B, and fall semesters.)
