Astronomy Clubs

Astronomical League
The Astronomical League is composed of over two hundred and forty local amateur astronomical societies from all across the United States. These organizations, along with our Members-at-Large, Patrons, and Supporting members form one of the largest amateur astronomical organizations in the world.

Calumet Astronomical Society
The Calumet Astronomical Society, Inc. (CAS) is a not-for-profit corporation founded in 1975, and incorporated in 2000, for the purpose of pursuing the study of astronomy and promoting the education of of astronomy and space science. The CAS membership consists of amateur astronomy enthusiasts from the Northwest Indiana and southern Chicago metropolitan regions.

Chicago Astronomical Society
The Chicago Astronomical Society is the oldest astronomical society in the western hemisphere, started in 1862. To this day, CAS continues to further its mission by maintaining an observatory, offering numerous venues for public outreach, conducting public observing sessions, and hosting monthly meetings and lectures. CAS also puts on two annual festivals each year: the Earth, Wind & Sky Festival and Astrofest.

Fort Wayne Astronomical Society
The FWAS is one of our 'neighbor' clubs base out of Fort Wayne, Indiana educating the Fort Wayne area about Astronomy and related sciences.

Kalamazoo Astronomical Society
The Kalamazoo Astronomical Society is one of our 'neighbor' clubs base out of Kalamazoo, Michigan educating the Kalamazoo area about Astronomy and related sciences.

Kankakee Area Star Gazers  
The Kankakee Area Star Gazers is one of our 'neighbor' clubs base out of Bourbonnais, Illinois educating the Kankakee/Bourbonnais area about Astronomy and related sciences.

Miami Valley Astronomical Society
We promote amateur astronomy at every level.  The MVAS serves two primary functions.  We promote education by bringing astronomy to the public through regular star-gazes at our dark sky sight at John Bryan State Park and provide a forum where members of the MVAS can get together, share ideas on Astronomy subjects.

Naperville Astronomical Association
The Naperville Astronomical Association had its beginnings as the Naperville High School Astronomy Club in the early 1970's. When the building of an observatory and telescope became the students' goal, it became necessary for them to form an organization outside the restrictions of a school sponsored group; in March of 1973 the Naperville Astronomical Association was founded. 

Warsaw Astronomical Society
The WAS is one of our 'neighbor' clubs based out of Warsaw, Indiana.  Whether a beginner or a long-time astronomy enthusiast, the Warsaw Astronomical Society can provide many opportunities for its members to help them enjoy the many fascinating aspects of amateur astronomy.
