View the night sky through large telescopes at this free public open house event.
Join us for FREE telescope viewing of the Moon, planets, galaxies, nebulae, and other celestial objects with SBO’s 20” telescopes! 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, or call us, on Friday night 15 minutes before scheduled time, 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 1-2 hours, depending upon the weather and the quality of the night.
