The Mornington Peninsual Astronomical Society (MPAS) is a volunteer-run, not-for-profit society founded in 1969 — the year of the first Moon landing. Today we’re a community of around 400 members, from curious beginners to seasoned amateur astronomers, who meet, observe and share the night sky from our observatory at The Briars, Mt Martha.
Meet & learn
Monthly meetings with member talks, guest speakers, Sky for the Month and the Astro Mo Pho photo challenge — plus a library of hundreds of books, magazines and DVDs and the bimonthly Scorpius magazine.
Observe together
Members’ viewing nights, telescope loans and Telescope Learning Days at Mt Martha Observatory — help always on hand, no gear required.

A long-running commitment to education — stargazing nights and talks for schools and community groups across the Peninsula and beyond.
