Explore the heavens with others who share your interest in astronomy.







Star Parties & "Nights Out"

The Chester County Astronomical Society offers "nights out" to interested organizations including local schools, scouting groups, and other civic groups for the purpose of learning more about the heavens. For example, scouting groups often hold them to earn badges for their members. If your organization is interested in hosting a Night Out, please contact our coordinator, Don Knabb.


Star Parties are similar to our "Nights Out" but are open to the public and are organized at the national and regional level. Listed below are upcoming star parties; click on the star party title for more information directly from their website.
