Welcome to Sydney City Skywatchers

Established in 1895, Sydney City Skywatchers carries forward a proud tradition of providing a forum dedicated to amateur astronomers and astronomy enthusiasts in the city. 


Since 1895 our aims to service the amateurs in astronomy have not changed. We are inclusive and welcome new members from Sydney and beyond.

We acknowledge and pay respect to the Gadigal people of the Eora Nation. It is upon their ancestral lands that Sydney Observatory, the home of Sydney City Skywatchers, is built. As we share our own knowledge and learn about astronomy and its heritage, may we also pay respect to the knowledge embedded forever within the Aboriginal Custodianship of Country.

Should you wish to visit Sydney Observatory please contact the Museum of Applied Arts and Sciences.

Our Next Event

Cataclysmic Variable Stars: Searching for ripples in the cosmic Niagara Falls

Dr Ian Kemp

Monday 2nd August 2021, 6:30 to 8pm

This talk is about “UGSU cataclysmic variables” - one of the most interesting species in the variable star zoo. They are binary systems, in which a red star spills material onto a white dwarf, giving rise to periodic massive eruptions which can brighten the system from magnitude 15 to magnitude 9, easily within the range of a backyard telescope.

Ian Kemp works as a research scientist at the International Centre for Radio Astronomy Research (ICRAR) in Perth - working partly on ‘big data’ (astronomically large data!) and partly on astrophysics research.


Members will also present their observations.
