Nothing to prove.
Just look up.
CAS welcomes beginners and experienced observers across the ACT and surrounding region. You can attend up to two monthly meetings before deciding whether to join.

Choose a current event
Dates can change. Use the official CAS calendar as the source of truth for the next meeting or public observing night.

Come curious
You do not need your own telescope or prior knowledge. Bring warm layers, questions and time for the weather to surprise you.

Confirm before leaving
CAS has strong links with ANU at Mount Stromlo. Check the event listing for its exact location, time and weather status.

02 / A society that observes
The universe is better shared.
CAS connects talks and practical observing, from a first view of the Moon to member-led astrophotography and outreach.
Dark-sky nights
Shared observing sessions, public viewing nights and telescope access.
Skills and equipment
Introductory guidance, telescope loans and help finding your way around the sky.
Public outreach
School visits and events that make astronomy tangible beyond the society.
Why this redesign exists
Awe should have a clear invitation.
I already loved astronomy and often went to ANU astronomy facilities to observe the night sky. Discovering CAS made me want more people to find that same sense of scale and wonder.
This concept turns that personal route into a simple first step for someone who has never attended before.
03 / From our sky outward
One night can change your sense of scale.
These NASA images are not a promise of what will be visible at the next CAS event. They show the worlds and deep-sky structures that keep observers curious.
Our nearest world
Familiar to the eye, transformed by magnification into maria, rays and cratered terrain.

Weather at planetary scale
Juno's close view turns a distant point of light into layered, turbulent atmosphere.

A stellar nursery in colour
Hubble's mosaic makes star formation feel like a landscape of light, gas and dust rather than an abstract distance.
