Atacama Large Millimeter/submillimeter Array (ALMA)

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 web site.  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.

Alan Hirshfeld, University of Massachusetts: From Backyard to Mountaintop: The Adventures of History’s Best Worst Telescope
Tuesday, January 13, 2014 at 7:30 p.m - Bowen Hall, Princeton University

Alan Hirshfeld, Professor of Physics at the University of Massachusetts Dartmouth and an Associate of the Harvard College Observatory will present a talk entitled “From Backyard to Mountaintop: The Adventures of History’s Best Worst Telescope”. The 36-inch reflector of English amateur astronomer Andrew Common made its way from a London backyard to a Yorkshire estate and ultimately to a mountaintop observatory in California. This little-known telescope, built in 1879 and still operating today, revolutionized celestial photography and proved to 19th-century astronomers that the future of cosmic discovery lay in the camera, not the human eye.

Alan Hirshfeld has authored a number of books including Parallax: The Race to Measure the Cosmos, The Electric Life of Michael Faraday, and Eureka Man: The Life and Legacy of Archimedes. He is a regular book reviewer for the Wall Street Journal and has contributed to Sky & Telescope, the American Journal of Physics, BBC History Magazine, and American Scientist. He has made radio and television appearances on NPR, PBS, and C-SPAN and lectures nationwide about science history and discovery.
