Open every Friday, 8:30 p.m. – 10 p.m. – Free

Tucked away on the roof of the Museum’s parking garage, the Gilliland Observatory is a wonderful resource
for our starry-eyed public. Join us on the roof every Friday night for a stellar presentation equipped with a
computer-controlled, Celestron CGE 1100 Schmidt Cassegrain telescope and staffed by knowledgeable
Museum employees.

Please call the Gilliland Observatory hotline, 617-589-0267, which is updated at 5:30
p.m. on Friday nights with information about that night’s observing session. Visit mos.org for more
information.
