Note: All meetings (except observing nights) are held at 7.30pm at Regis Hall, St. Ignatius’ College, Riverview

We are a society based in the northern suburbs of Sydney (NSW, Australia), containing a number of streams to cater for astronomy related interests at all levels.  We have a number of core streams and activities at NSAS and these are listed below. Please visit the site regularly to get updated news on our upcoming events and activities.  Our core streams/activities are:

Monthly Meetings (Third Tuesday of the month)
Once a month (at 7:30pm on the third Tuesday of the month) we meet at Regis Hall in the grounds of St Ignatius’ College, Riverview Street, Riverview (Lane Cove) (click here for a map).  This meeting focuses on the theoretical aspects of astronomy, each month featuring a guest lecturer, and touching on subjects such as cosmology and astrophysics.
ANNOUNCEMENT:There will be no guest speaker for September. Instead we will have a Telescope Workshop on Tuesday 18th September. Details below:

We have had several requests from members to conduct a Telescope Workshop. This will allow members to bring in their under-utilised scopes and get helpful advise from our more senior members as to how to get the best out of it.
We will either be in our normal meeting room (ground floor) or the large meeting room above (car park level). This will save people dragging their scopes down the stairs.
Visitors who are interested in getting back into astronomy are most welcome. They can bring along their own scopes or come along to have a look at other people’s scopes.


New Astronomers Group
The New Astronomers Group is a great course for people who have recently purchased or plan to purchase a telescope and would like to learn how to use it. The group also caters for those of us who are have had their telescopes for a while and are interested in talks and presentations on the latest updates in astronomy. Topics we cover include star-hopping the night sky, learning to use your telescope more effectively, astrophotography and other practical areas of astronomy.

ANNOUNCEMENT: The NAG course is run every year. The next NAG course will be run in 2019. If you wish to be contacted for the next event please send an email to
Observation Nights
Observing nights take place at Terrey Hills, usually on the Saturday before and after the New Moon. We start around sunset and continue until everyone has had enough.
You don’t need to have your own telescope to attend viewing nights. The club has its’ own telescope (an 8” Dobsonian) which members can borrow. The observing schedule can be found at
Each month we hold a visitors night ($10 per adult donation, $5 per under 16s donation) and a members only night. Visitors with telescopes will be permitted only one $10 observing night, after which they must become a member of the Society to continue to enjoy the outstanding facility at Terrey Hills. These visitor nights give you an opportunity to find out more about us. If you would like to join us, please click the Join Link in the menu above. Please note that general meetings are not held during the month of January. However, observing nights are still held.
We have a new Astrophotography group. To assist with sharing information, please check out the AstroPhotography Forum.
