Welcome to the website of the Cedar Amateur Astronomers, Inc.

Thank you to all who attended our events!

As well as being a member society of the Astronomical League, the CAA is a member of NASA's Night Sky Network, a nationwide coalition of amateur astronomy societies committed to sharing their time, their telescopes, and their enthusiasm for astronomy with their local communities. The CAA hosts public viewing nights during the year and information about those public observing nights can be found on the Events page of the website.

The Society serves its members, the public, local school districts, youth groups, as well as college and university classes. We have also hosted state and regional conventions in Cedar Rapids. Since its founding, the Society's membership has grown from 12 members to over 100. Our members come from all walks of life and with all levels of interest in astronomy.

The Cedar Amateur Astronomers, Inc. was founded on September 29, 1979, and incorporated in 1980. Based in Cedar Rapids, Iowa, the CAA is a tax-exempt, non-profit 501(c)(3) organization. The Eastern Iowa Observatory and Learning Center at Palisades-Dows Preserve is jointly operated by the Cedar Amateur Astronomers and the Linn County Conservation Board.
