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. 


We meet at 6:30pm on the first Monday of the Month at Sydney Observatory. Typically there are short astronomy reports from members, and then a guest speaker or telescope viewing opportunity. You don't need to have any specialist knowledge, or own a telescope to enjoy, participate in and learn from these sessions but a passion for astronomy is a must! 


Since 1895 our aims to service the amateurs in astronomy have not changed.

Should you wish to have a night telescope tour of Sydney Observatory please contact the Museum of Applied Arts and Sciences (MAAS).
