Astronomical Observatory

Astronomical Observatory


The Association for Astronomy (Department of Physics and Astronomy) invites you to observe the cosmos with your own eyes at the Macquarie University Astronomical Observatory. View planets, moons, binary stars, star clusters, nebulae and bright galaxies through our newly upgraded 12″ and 16″ professional in-dome telescopes. You will be guided by our knowledgeable astronomy staff, so please bring along any astronomy questions you may have.

Friday and Saturday night observing sessions

Observatory sessions are currently held on Friday and Saturday nights between February to October (excluding public holidays). These sessions run from 8pm – 9:30pm during daylight saving time (Oct to Mar/Apr), and 7pm – 8:30pm during the rest of the year.

Bookings are essential: all tickets for admission are sold online. We are unable accept cash at the door. Please visit our Eventbrite page to view available dates and to purchase tickets.

Attending the observatory is weather dependent... unfortunately we can't see the stars if it's cloudy or raining. A decision will be made by 5pm on the day as to whether the observing session will go ahead or be cancelled. In either case, an announcement will be posted to our Facebook page. Full refunds are issued in cases of bad weather. Minimum sales are required for sessions to go ahead, and limits apply so book early to avoid disappointment.

You can find tickets here.

Private bookings: school, Scout or small groups

For all enquiries about school or scout groups, private bookings, off-site visits and tailored observatory, telescope and/or planetarium sessions, please complete this online form. A member of staff from the AfA will respond to your enquiry once they have had a chance to review the request. Note that costs for any private session will be determined on the basis of complexity, duration, group size, equipment and staff required.

Teaching activities

Radio Astronomy

The 3.2-metre radio telescope at the observatory is a small dish, suitable for observing the Sun. With radio astronomy we do not see an image, as with an optical telescope, but can map the signal strength in different directions on the sky. The main purpose of the radio telescope is to educate students in the basics of radio astronomy.

Optical Astronomy

Several of our astronomy units have an observing component, where students visit the observatory at night to observe various astronomical objects. This program has also now been expanded to include use of our new CCD camera for astrophotography.

Undergraduate Units in Astronomy

Research activities

MRes and PhD Research Projects

From time to time, post graduate projects are conducted at the observatory. Optical astronomical equipment used in conjunction with the telescopes includes CCD cameras for imaging and photometry, and a single-fibre spectroscope for obtaining object spectra. For more information please go to the Higher Degree Research Page for the Department of Physics and Astronomy.

History of the Observatory

The Macquarie University Observatory was originally constructed as a research facility but, since 1997, has also been accessible to the public through its Public Observing Program on Friday nights. The Observatory saw a record crowd on the night of 29th August 2003, with 667 visitors attending to observe the Opposition of Mars.

The Observatory was first opened in 1978 at a different location.  The Association for Astronomy was established in 1988 by Dr. Alan Vaughan to raise funds for further development of the observatory, which was moved to its present site in the early 1990s. The second dome, which houses the 16″ Meade telescope, was opened by Professor John Loxton on 3 May 1997. Construction of this dome was funded by Macquarie University and the Foundation for Astronomy (now the ‘Association for Astronomy’).

The Public Observing Program was operated from 1997 until the end of 2001 by a privately-operated business: Southern Skies Mobile Observatory.  From 2002-2011, the Public Observing Program has been operated by astronomy undergrad and postgrad students.  Much of this work was voluntary.  As of 2012, the observatory is operated by trained staff through the revamped Association for Astronomy.


Unfortunately observing through the telescopes is reliant on the weather being optimal for the session to go ahead. We use multiple sources to predict the weather which are shown below:

Bureau of Meteorology

Radar loop for the local Sydney area produced by the Bureau of Meteorology. A lot of data on this website that is useful for predicting the local forecast.

Clear Outside

This website also has an app for iOS and Android and contains a lot of useful information such as Cloud Coverage, rain indicator and an indicator of any passovers by the International Space Station. By simply choosing your location (the link above is for Macquarie Park) you can get the local forecast and all the other information needed to decide on your observing likelihood. Click here for a guided tour of the website.

Norwegian Meteorological Institute

Another website that give a handy forecast of the local conditions in regards to cloud coverage and rain. Created by the Norwegian Meteorological Institute and also having a place to enter a location (North Ryde is the choice in the above link), you can get a fairly accurate prediction of the local weather.

This website shows the star map of your location (Macquarie University uses Lat: -33.78 Long: 151.12) for any time you enter. Quick and easy to show what astronomical objects may be visible from your location.
