The Big Sky Astronomical Society is based in Alberta, Canada. We own and operate an 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.

We are a registered charitable organization and as such we rely on donations and grants to sustain and expand our operations. All donations are tax-deductible to the extent allowed by law. If you would like to help us further our educational objectives please make a donation. Thank you!
