Founded in 1979 to promote and practice astronomy in East Central Iowa, membership in the Cedar Amateur Astronomers, Inc. is open to any individual, student or family interested in astronomy. Since its founding in 1979, membership in the society has grown to over 100 enthusiasts from all walks of life and all levels of interest and ability.

Members receive our monthly newsletter The Prime Focus, discounts on astronomy books and magazines, and membership in the Astronomical League. The society also moderates a Yahoo! discussion group where members may discuss all things astronomical, and you may wish to social network with other amateur astronomers and interested individuals at our Facebook group page.

Members may qualify for discounts at popular online shopping sites just by telling the retailer that they are a member of Cedar Amateur Astronomers. Oceanside Photo and Telescope (www.OPTcorp.com) will discount some items and Astronomics (www.astronomics.com) also promises discounts to Astronomy Club Members, as well as operating the popular astronomical equipment review site CloudyNights.com. If you are contemplating an astronomical equipment purchase (aren't we all?) you could easily save more than your annual membership dues in discounts just by being a member.

Our society meets monthly on the first Thursday of the month. Check the Prime Focus newsletter for location and starting time. Generally the meeting is held at the Pal Dows EIOLC and begins at 7:00 p.m. During the winter months the meeting is moved to the St. Luke's Hospital Resource Center in Cedar Rapids and begins at 7:30 p.m.

Additionally, CAA members are entitled to the use of the facilities at Palisades-Dows Preserve. It's a great opportunity to visit with other society members in an informal setting, get checked-out on the use of society instruments and equipment or simply enjoy the beauty of the night sky with other enthusiasts.

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.
