Enthusiasm for observational astronomy, curiosity about cosmology, achievements with CCD imaging and technology. These and all other aspects of astronomy are interests shared by members of the Amateur Astronomers Association of Princeton. The club is based in Princeton, (Mercer County) New Jersey.

This organization of 100 + promotes astronomy-related activities for members and non-members, novice to expert. A wide spectrum of astronomy interests are explored at the AAAP through regular meetings, workshops, use of the two club observatories, public outreach and regional star parties.

Come explore our images - produced by members of the AAAP. Here you'll find details about our organization's meetings, discussion topics, members and their scopes, and a lot more. Our organization maintains two observatories: the larger in Washington Crossing State Park (housing a research-grade 355mm Schmidt-Cassegrain catadioptric and historic 159mm Hastings-Byrne refractor). A second facility is found at Jenny Jump State Park in northwestern New Jersey. This houses a 318mm custom-built Newtonian reflector.
