To promote a greater appreciation and awareness of astronomy in our local area and beyond.

The Big Sky Astronomical Society is based in Alberta, Canada. We own and operate a small observatory situated under a dark sky and located approximately midway between Calgary and Lethbridge. Although we only have a few dozen members and limited resources, we work hard to promote a greater appreciation and awareness of astronomy in our local area and beyond. Our members can borrow telescopes, astronomy books, astronomy videos, and astronomy software. They also enjoy an annual barbecue in August and have year-long access to a fine observatory located under a dark sky.
