Amateur Astronomers, Inc. (AAI) is an amateur astronomy organization in
Central New Jersey. Founded in 1949, it currently has over 200 members,
making it one of the largest astronomy clubs in the United States.
The home of AAI is the William Miller Sperry Observatory on the campus of the Union County College in Cranford, New Jersey. The observatory houses two of the largest telescopes on the East Coast for amateur use. The East Dome holds a 10-inch f/15 refractor built by AAI members. The West Dome has a 24-inch f/11 Cassegrain reflector purchased by AAI.
In September of 2000, AAI dedicated the Barry D. Malpas observatory in our dark skies site in the Jenny Jump State Forest in Hope, New Jersey. This facility houses our new 14-inch Celestron C1400 Schmidt-Cassegrain telescope.
