The Colorado Springs Astronomical Society© (CSAS) is a nonprofit 501(c)(3) organization dedicated to the enjoyment of the nighttime sky. Our club is a member society of the Astronomical League (AL) and the International Dark-Sky Association (IDA). CSAS is an equal opportunity service provider. Some events are held under permit in the Pike National Forest.

We currently have over 100 members that regularly meet to observe the splendors of our dark, dry, Colorado skies. In addition to monthly observing sessions, we hold monthly membership meetings on the fourth Tuesday of each month at the BSCS Building, which is located at 5415 Mark Dabbling Blvd. Click here for a map. The meetings are held at 7 p.m. and usually consist of a short business meeting and a program presented by a member or guest speaker.

Our membership is diverse in age, education, occupation, astronomical experience and expertise. Some members have formal training in astronomy, but the majority are non-technical hobbyists. Many are beginners* who merely want to increase their understanding of the heavens.

Star parties are our most frequent activity where we meet at a dark sky site and observe the night sky. Typically, we schedule one official monthly star party and club meeting. However, many members get together on short notice for impromptu observing sessions throughout the month. Members are contacted for a last-minute impromptu through our listserver.

CSAS hosts public star parties, often in conjunction with nature education programs of the El Paso County Recreation Department. We sponsor public viewing sessions at Bear Creek Nature Center, Memorial Park, Sky Sox Stadium and other local facilities. Also, we present astronomy programs for local schools and nonprofit organizations through our Project Astro program.

During June-July, we host a weekend astronomy camp-out called Rocky Mountain Star Stare© for astronomy enthusiasts throughout the country and abroad. We also attend and support similar events sponsored by other Rocky Mountain clubs.

CSAS is also the administering society of the newly developed Earth Orbiting Satellites Observers Club (EOSOC) program for the Astronomical League. This new observing program is open to all League members and MAL’s throughout the United States and overseas.

*Owning a telescope is not required for membership in CSAS. All we do require is a spirit of adventure and willingness to enjoy the night skies.
