BSAC Gains Tax-Exempt Status

June 30, 2011

The Big Sky Astronomy Club was created during the fall of 2000 as Non-Profit corporation, registered with the State of Montana. This, however, didn't afford us tax exempt status with the Internal Revenue Service.

During the first months of 2011, club members began the arduous task of assembling the documentation necessary to apply to the I.R.S. for 501(c)(3) tax-exempt status.

On July 30, 2011, we excitedly received word from the I.R.S. that our application had been approved and that the Big Sky Astronomy Club was now (and retroactively to our formation in October of 2000) considered to be a 501(c)(3) tax exempt, non-profit, charitable organization. As such, contributions to our club are fully tax deductible.

If you'd like to help out with a donation, the club has a PayPal© account set up. See our "About Us" page for more information.

Transit of Venus 2012

The Big Sky Astronomy Club hosted a public observing session and PowerPoint presntation at Flathead Valley Community College during this year's Transit of Venus on June 5.

A.C.S.  Relay For Life

June 22, 2012

American Cancer Society Relay For Life

The Big Sky Astronomy Club participated in this year's Relay For Life, sponsored by the Amercian Cancer Society.

Club members had telescopes set up for participants in the marathon walk to view deep sky objects during their down time. In addition, Club President Mark Paulson had a homemade "cosmic ray cloud chamber" set up, with which indviduals could actually see the tracks left behind as cosmic rays passed through the chamber.

G.N.P. Summer Stargazing

Summer Weekends, 2012

The Big Sky Astronomy Club once again worked with the management of Glacier National Park to put on a very successful Summer Stargazing Program at various locations on the west side of the park. Literally hundreds of visitors got a chance to view sunspots on the face of our Sun during daylight hours and then, each evening, they had an opportunity to view many of the interesting objects visible through telescopes of various types and sizes.
