Visit the Mendel Observatory

The Observatory, located on the top floor of the Mendel Science Center at Merrimack College, houses an Optical Guidance Systems 20-inch Ritchey-Cretien reflector and a number of electronic imaging systems, and is used by students, faculty, the North Shore Amateur Astronomy Club, and the general public.
