Mendel Observatory

Mendel Observatory

The Mendel Observatory is home to a 20-inch Ritchey-Chretien reflector and a number of electronic imaging systems. It is located on the 4th floor of the Mendel Science Center at Merrimack College. The observatory is used by students, faculty, the North Shore Amateur Astronomy Club and the general public.

Public Stargazing

With the support of volunteers from the North Shore Amateur Astronomy Club, the observatory hosts public stargazing every Wednesday night, weather permitting, starting at dusk or 7 p.m., whichever is later. When special astronomical events of interest occur, such as a total lunar eclipse, the observatory often holds special viewing times. Stay tuned for upcoming events!
