Welcome to the official website of the Cumberland Astronomical Society.  We are a group of amateur astronomers based in Gallatin, Tennessee.  Our focus is to bring astronomy to the general public in the upper middle Tennessee area.  We hold several monthly events at local schools, libraries, and parks. Everyone is welcome, so please click the "EVENTS" link for dates and times.

One of the advantages of membership in the Cumberland Astronomical Society is that we are a member of The Astronomical League, which is composed of over 200 astronomy clubs from all over the United States.  Several of these member societies sponsor Observing Clubs, which award pins and certificates upon completion.

This month, we'll focus on the Double Star Club, which is managed by Nashville's own Mike Benson of Barnard-Seyfert Astronomical Society.

The purpose of the Double Star Club is to introduce observers to 100 of the finest double and multiple stars in the heavens. You don't need a large, expensive apochromatic refractor to view the objects on this list since a small refractor, Newtonian reflector, or Schmidt-Cassegrain will do just fine. All objects on this list were originally observed with a three-inch refractor using between 75X and 150X. Again, this program is meant to allow you to enjoy a different aspect of our wonderful hobby, and not to test your equipment.

Double star observing can be very forgiving. You don't need the darkest skies, the clearest skies, or even a moonless night to observe many of these objects. Some can be observed from your backyard under moderate light pollution, some can be observed under less than transparent skies, and some can even be observed with the moon up. However, as usual in astronomy, the best results can be obtained under optimum conditions. The point is, always try for the best conditions, but if you don't have them, don't worry about it. You can still enjoy this program.
