Welcome to the Astronomical Society of South Australia

The Astronomical Society of South Australia is the only representative body for amateur astronomy in the state of South Australia. Founded in 1892 and with around 700 members, it is the oldest and one of the largest organisations of its kind in Australia.

Our monthly meetings, which usually feature a guest speaker, are free, open to the public and visitors are most welcome to attend.

ASSA@Home Casual Friday

This is a free-flowing live video session where members can discuss any aspect of our wonderful Astronomy hobby and the night sky. Topics can include how to find objects in the night sky, what equipment, software or books to buy, sharing something that has helped you in doing Astronomy, or general questions about ASSA and its facilities. The session is designed to be accessible and of interest to members at all levels.

ASSA@Home Summer Observing Targets

Friday, 18 December 2020 7:30 PM

The night sky is full of deep-sky targets for beginners and experienced observers alike. With winter gone, the warm nights of summer have finally arrived. There’s no better time to wipe the dust off that telescope, and join Paul Martinaitis and Joe Grida as they take us on a tour of the most spectacular and some rarely seen objects in our summer night sky. From nearby emission and planetary nebulae, to galaxy groups, and quasars halfway across the Universe, you’ll be equipped with a vast list of target objects to keep you observing all summer!
