Open Houses

Fall 2026 Schedule

Artemis telescope viewing the night sky.

Our FREE Open Houses are held on most Friday evenings when CU classes are in session. We hope to see you there!Ìý

New this semester! Open House nights will shift forward as the sun sets earlier and earlier towards the winter months. We hope this change will allow more young visitors to enjoy the observatory!

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, check our facebook or instagram an hour before scheduled time,Ìýor call us, on Friday night 15 minutes before scheduled time for an observing status at 303-492-2020.Ìý

There is no charge for the Observatory's Open House nights ... the stars are free to everyone! Sessions typically last from 1-2 hours, depending upon the weather and the quality of the night.
