The Cheyenne Astronomical Society (CAS) was formed in December of 1986. The CAS is for people interested in astronomy who want to share their experiences and increase their knowledge about astronomy. Members are not required to own any equipment or to have any knowledge of astronomy. Your basic curiosity about astronomy is all you need. We hold a monthly gathering at Primrose Retirement Community. Observing sessions for special occasions, such as meteor showers, comets or eclipses are also planned when the opportunity arises.
The CAS is proud to be associated with the following organizations.
