  • 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".

1. The best Saturday night of the cycle (i.e. closest to New Moon) is allocated to The Forest & second best to Stargard

2. Public nights are usually scheduled close to FQM. This suits the public who wish to view bright objects; the moonlight satisfies public safety concerns; and avoids cancellation of members observing nights. There is also potential for pubic nights to be nominated on a night when the Moon spectacularly rises during the event.
3. The annual International House Students Night is normally held in August and the date proposed, to avoid clashing with regular observing nights.

4. The times allocated to The Forest relate to the Saturday.

A list of bright deep sky objects which is supplementary to the Messier List, which missed several objects worthy of listing  - and listed nothing south of 35° S. The first fourteen items (C1-C14) are not visible from Macarthur's 34° S latitude. The dates of the highest passing of the objects are approximate.
