Welcome to the BASS Home Page

The Boulder Astronomy & Space Society is dedicated to the interests of the observers and space enthusiasts of all types in Boulder, Colorado. It is our goal to provide common ground for Boulder's amateur, professional, and academic communities to share their enthusiasm about the universe around us. Our meetings are generously hosted on the University of Colorado campus at Fiske Planetarium and Sommers - Bausch Observatory and are open to students and the public alike. See the Events page for more details.

To join BASS come to a meeting or fill out this form and mail it in along with your check to the Boulder Astronomy and Space Society, PO Box 17203, Boulder CO 80308.

 

No usual BASS Meeting in May. Instead please support the Partial Solar Eclipse and Astronomy Day at Sommers-Bausch Observatory and Fiske Planetarium, Sunday May 20th, Noon-10PM. The emphasis will be on solar observing, with evening observing on the telescope deck after sunset. We very much need volunteers for operating the BASS solar telescopes during the eclipse, and potentially the BASS 10" dobsonian in the evening.

 

 

 

 

 

Ethos meets FirstScope - BASS pushes the limits of new equipment testing at a BASS meeting!

Possibly a first, $600 eyepiece on a $30 telescope. While not exactly compatible, both components do have their merits!
