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 at 7 p.m., or call us, on Friday night after 7:45 p.m., for an observing status at 303-492-2020.

We have bilingual nights! Folks can attend an English/Spanish Open House event on Feb. 20, March 27, and April 17!

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.
