Macarthur Astronomical Society
Amateur Astronomy in South Western Sydney
Welcome to MAS!
We are amateur astronomers in the South Western Region of Sydney, Australia, including Campbelltown, Camden, Liverpool and Wollondilly local government areas of NSW.
We hold regular dark sky observing sessions for our members to advance our skills.
We bring local and international guest speakers to address our monthly Macarthur Astronomy Forum at the Campbelltown Campus of Western Sydney University.
We organise public astronomy nights in collaboration with Campbelltown Rotary Observatory at Western Sydney University and we collaborate with local institutions to maximise knowledge of the Universe in the local community - including school mentoring.
