Sutherland Astronomical Society Incorporated Astronomy, Astronomy Club, Astronomical Society, Amateur Astronomy The meeting hall was completed in 1974 and a roll-off roof observatory was completed in 1996.

SASI was formed in 1961 when a small group of people constructed an observatory south of the Georges River in the leafy southern suburbs of Sydney. The Society was known, until 1978, as the James Cook Astronomers Club and the James Cook Astronomical Society. The present Green Point Observatory is located on Council land at the corner of Green Point and Caravan Head Roads, Oyster Bay. The prominent silver dome, with its 41cm (16”) Newtonian telescope (now refurbished) and the library were completed in 1970. This now contains a state-of-the-art 35cm (14”) Celestron Schmidt Cassegrain telescope. The buildings were joined, meeting hall extended and toilet added in 2007. The objects of the society is ”to promulgate knowledge of the astronomy to the public; common interest & exchange of ideas & data in astronomy; & provide a facility for mutual & social benefit of its members ”. Meetings:
The Observatory is open every Thursday evening from 7.30pm. Visitors are welcome, but groups should book first by contacting Craig Goulden (Star Night Booking Officer).
★ 1st Thursday of the month: Guest lecturer.
★ 2nd Thursday: Committee meeting & Sci-fi night.
★ 3rd Thursday: Cosmology Club
★ 4th Thursday: Special interest workshops (society telescopes & how to photograp nebulae etc)
★ 5th Thursday: social (trivia, popcorn & movies etc)
Check the notice board and the website for any special programs or events. Meetings subject to change, which will be advised by email and posted on website. Other activities during the year (annual dinners, observing in dark locations, Tues picnics etc). Quarterly journal for members

🪐 Can we just take a moment to appreciate how ridiculously cute Saturn is?! ✨

With those gorgeous little rings, it’s hard not to have a soft spot for the jewel of our Solar System!

Did you know Saturn’s rings are made up of countless pieces of ice and rock? Despite stretching hundreds of thousands of kilometres across, the main rings are surprisingly thin, measuring just around 10 metres thick in many places!

🔭 This beautiful image was captured by our member Thu Nguyen, using a Sky-Watcher Esprit 120 telescope and ZWO ASI662MC camera.

Thu captured 4,000 frames and stacked the best 25% to bring out the details of our favourite ringed planet!

A huge thank you to Thu for sharing this adorable little Saturn with us! 💫

🔭 This Week at SASPAC – Week 6! ✨

Did you know that the Sutherland Astronomical Society (SASI) runs a beginners astronomy course once a year?

SASPAC is our 8-week introductory course, designed to help newcomers discover the wonders of the night sky! From identifying stars and constellations to understanding telescopes and exploring the universe beyond our Solar System, the course combines fascinating discussions with hands-on activities to help participants develop their astronomy skills.

🌙 This week was all about Deep Sky Objects!

In Week 6, our participants explored some of the most spectacular sights in the night sky, including:

✨ Nebulae – enormous clouds of gas and dust, some of which are stellar nurseries where new stars are born.

⭐ Star Clusters – beautiful collections of stars, from loosely grouped open clusters to densely packed globular clusters containing thousands or even millions of stars.

💫 Galaxies – vast systems of stars, gas and dust, including our own Milky Way!

With just two weeks remaining, our participants are well on their way to becoming confident amateur astronomers!

🔭 Interested in exploring the universe yourself? SASPAC runs once a year, so follow our page to hear about next year’s course!

🌌 A cosmic eye staring back at us! 👁️🔭

Meet the Helix Nebula (NGC 7293), sometimes nicknamed the Eye of God thanks to its striking resemblance to a giant eye in space!

Located approximately 650 light-years away in the constellation Aquarius, the Helix Nebula is one of the closest bright planetary nebulae to Earth.

Despite the name, planetary nebulae have nothing to do with planets! They’re formed when ageing stars shed their outer layers of gas into space, leaving behind a hot, dense core called a white dwarf. The ultraviolet radiation from this stellar remnant causes the surrounding gas to glow, creating spectacular structures like the Helix Nebula.

📸 This stunning image was captured by our very own SASI President using a Seestar smart telescope, with an impressive 406 minutes (6 hours and 46 minutes) of imaging time!

✨ Just one of the incredible sights hiding in our night sky.

The Sutherland Astronomical Society Inc. (SASI) is excited to be joining Instagram!

We’re a community of astronomy enthusiasts brought together by a shared love of the night sky.

Whether you’re an experienced astronomer, just getting started with your first telescope, or simply someone who loves looking up at the stars, there’s a place for you here!

We’ll be sharing astrophotography from our members, upcoming events, observing tips, fascinating facts about the universe, and plenty of reasons to look up!

✨ Follow along as we explore the universe together, one clear night at a time.

Clear skies! 🔭

Petition for National Legislation for Light Pollution Regulation and Dark Sky Preservation.

Hi SASI friends,
We try not to impose on our valued followers, but there is a very important petition to try and limit light pollution so we can continue to see the wonders of the sky at night, even from our suburban location in Oyster Bay. In the last 10 years I have noticed the sky is getting so bright that there are objects like faint galaxies that we can no longer see at all, and we have lost our view of the Milky Way entirely. If we don't do something about it, our children won't be able to see stars, and if we can't see something we unfortunately won't care about it. It would be a shame for future generations to not ask the big questions about the universe because they can't see the stars to be inspired to think about it.

The petition's closing date is 19 September, and we have 9,060 signatures of the required 10,000 for the petition to be heard in parliament. So, we need an additional 940 signatures in the next 4 days.

Please sign the petition via the link below and pass it on to all your contacts for their help.

Kind regards and clear skies,

2025 August Open Night Recap.
It was another clear night last night, and it seemed everyone enjoyed the experience. Thank you to all who attended as this event makes a major contribution to our astronomical society being able to fund the expense of maintaining an observatory for the education and entertainment of the community. I hope we contributed to some budding young astronomers heading down the path of a career in Science, Technology, Engineering and Mathematics. 🔭👩‍🎓👩‍🏫
