About SBO

est. 1953


General Information

Sommers-Bausch Observatory (SBO) on the University of Colorado campus is operated by the Department of Astrophysical and Planetary Sciences (APS) to provide observational experience for CU undergraduate students, and hands-on training in astronomical observations and instrumentation for departmental majors and graduate students. Telescopes include 16, 18, and 24-inch Cassegrain reflectors and a 10-inch aperture heliostat.

Recent Improvements

This year (2015) our computer lab went thorough major revision, including a new server and 40 new terminals controlled via raspberry pi's.

Past improvements include new audio/video equipment and wireless campus internet service now available throughout the building. Work this past year has emphasized trying to modernize the 55-year-old building's physical appearance: new carpeting for the Observing Deck and Dome Room, new paint for the Dome Room, Astronomy Lab, and Machine Shop, new window coverings and improved lighting for the Astro and Cosmos Labs; and new furniture, optical bench, whiteboards, and overhead projection systems. The new Student Lounge is a place for students to relax, rest during an all-nighter at the telescopes, or for TAs to hold office hours; it boasts new paint, furniture, window coverings, floor coverings, lighting, and (hopefully) soon a new a/v system.
