Welcome to MPAS
MPAS is a volunteer-run Astronomical Society, located at Mt Martha on the Mornington Peninsula. It was founded in 1969 to foster the study of all aspects of Astronomy, Space and general Science by volunteers and to promote these to the public.
You can visit us at one of our popular public stargazing nights, where you can learn more about the Universe and take a look through our telescopes at the planets, the Moon and the stars.
We hold a monthly general meeting for the exchange of ideas and information. For decades the Society has provided “Astronomy on the Move” educational presentations, including observing nights for schools and community groups exclusively in the Peninsula and surrounding areas, as well as special exhibitions in the Melbourne CBD and Melbourne Museum.


Mt Martha Observatory is the Society’s registered astronomical observatory at The Briars Historic Park. It is used to further the Society’s educational, research, innovation and recreational capabilities. Historically this was the first registered amateur observatory in Australia and is one of a network of registered global monitoring stations of night sky light pollution. The Observatory is registered with the Astronomical Society of Australia. We acknowledge the land, water, and sky under which we meet are of the Bunurong and Boon Wurrung peoples and we pay our respects to their Elders past and present.
