About the Club & History

The Northwest Suburban Astronomers (NSA) club began in 1968 with Jack Kramer and neighbors meeting informally, officially established on June 5, 1971. In 1976, NSA merged with the Northwest Amateur Astronomy Club, growing to over 150 members. The club hosts monthly meetings, star parties, and summer camp-outs, and engages in public outreach. NSA won the 1989 Sky & Telescope Astronomy Day award and participates in the Night Sky Network and The Space Place to support NASA's missions. Membership benefits include newsletters, site access, trips, and discounts, fostering community spirit.
