The Allan I. Carswell Astronomical Observatory is located on York University's Keele Campus. It originally opened in 1969. The observatory owns two telescopes housed in separate domes: a 60-centimetre (24-inch) Cassegrain reflector and a one-metre (39-inch) custom-built telescope — the largest at a university in Canada.
