Stull Observatory is an astronomical observatory owned and operated by Alfred University located in Alfred, New York (USA) and named after John Stull, who helped establish the observatory in 1966. It is notable for housing seven independently housed telescopes ranging in size from 8 to 32 inches. The largest, the Austin-Fellows 32 inch Newtonian Reflector is tied with the Vassar College Class of 1951 Observatory for the rank of second largest optical telescope in New York state after the 40 inch telescope at SUNY Oneonta College Observatory. Telescopes at the observatory are regularly opened to the public. The observatory is also used for those pursuing a minor in astronomy or a concentration in astrophysics.
