Pukaki Observatory | Stargazing at Mt Cook

At the centre of the Observatory is our pier-mounted 9.25-inch Celestron Schmidt-Cassegrain telescope, alongside modern smart telescopes that allow guests to experience different approaches to observing and imaging deep-space objects. The Observatory also tells the story of how our understanding of the sky has evolved. Explore historic navigation tools and astronomical instruments used by early mariners alongside contemporary telescope technology, and discover how generations of people have used the stars to navigate, measure time and understand their place in the world.

This is an interactive experience. Handle genuine space materials and meteorite specimens, investigate scientific instruments and take part in demonstrations that help explain astronomical phenomena, including how aurora are created and why they become visible in our skies. Outside, your Astro Guide uses the naked eye and laser pointers to introduce the wider night sky before taking you deeper through the telescopes. Depending on the season and conditions, you may explore planets, nebulae, star clusters, galaxies, the Southern Cross and the Magellanic Clouds.

Science In Action

Pukaki Observatory is also connected to scientific research and the ongoing protection of the night sky. Our Fireballs 360 meteor camera system continuously monitors the sky for bright meteor events, contributing to the search for meteorites that may reach the ground in New Zealand. Guests can see the camera system and learn how observations from multiple locations can be used to calculate the path of a meteor through the atmosphere.

We undertake regular dark-sky quality measurements, contributing data to monitoring within the Aoraki Mackenzie International Dark Sky Reserve. These measurements help track changes in artificial light and support the long-term protection of one of the world's great dark-sky environments. The Retreat supports the wider astronomical community through its sponsorship of the Royal Astronomical Society of New Zealand, while our Astrophysicist-in-Residence programme creates opportunities for astronomy students, graduates, researchers and astrophotographers to share their specialist knowledge directly with guests.

Our Astro Guides

Our resident Astro Guides bring different areas of expertise to the Observatory, from astrophysics and astronomical research to deep-space and landscape astrophotography. They do much more than point out constellations or operate a telescope. Ask about their research, the physics behind what you are seeing, how a telescope captures an object millions of light-years away, why stars are different colours, how meteorites are tracked, or how scientists measure the increasing brightness of the world's night skies.

Science Beneath The Stars

The Observatory also contributes to astronomy and dark-sky conservation. Our Fireballs 360 cameras monitor the sky for meteor events as part of the search for New Zealand's next meteorite. We undertake regular dark-sky quality measurements that contribute to monitoring within the Dark Sky Reserve, and support the wider astronomy community through the Royal Astronomical Society of New Zealand. Protecting darkness matters not only for astronomy, but for the wildlife, landscapes and people who depend upon natural cycles of light and darkness.
