What We Do
We hold dark sky observing sessions for our members.
We organise the Macarthur Astronomy Forum, bringing local and international professional astronomers to address us on their research.
We organise community astronomy nights at Campbelltown Rotary Observatory at Western Sydney University and we collaborate with local institutions to broaden public understanding of the Universe.
Monthly Meetings with Guest Speakers
Online for Members.
During the pandemic our meetings are held online for members only. Logging in is simple and easy.
When we return to “normal” our meetings will again be held at Western Sydney University (Campbelltown) and be open to the public.
