  • welcome to

    macarthur astronomical society

  • observe

    Astronomers use scientific observation to learn about the Universe we live in. It's a beautiful place and, as a group of keen amateur astronomers, M.A.S. members have it as their common interest. We observe from two southern Sydney locations.

  • photograph

    Along with our "visual" observers, we have a group of dedicated astrophotographers within our ranks. This group find that photographing deep sky objects with high-quality cameras brings out the colour which your own eyes are unable to detect. See our photographs and you'll want to take your own.

  • educate

    Come to a Macarthur Astronomy Forum evening, held at UWS Campbelltown, to hear talks given by Australian and international professional astronomers as well as from amateurs with interests in their own specific fields. Entry is free for all.

  • events

    M.A.S. members are deeply committed to sharing our combined knowledge of, and love for, the night sky and the science of astronomy. We hold public open nights during the year - keep watching out for "What's On".

Macarthur Astronomical Society

Established 1996

We are amateur astronomers based in the Macarthur Region of South West Sydney, Australia.

We organise the monthly Macarthur Astronomy Forum and run observing sessions for members, for the public and for community organisations. However, we regret that our Public Outreach Programme is suspended for the duration of the public health crisis.
