Dark Sky Project is proud to be home of the newly restored the Brashear Telescope. A marvel, beautifully crafted of brass, iron, steel and wood, the Brashear Telescope stands nine meters tall and has an 18-inch refracting lens. As one of the most important telescopes of its era, this masterpiece of Victorian engineering deserves and has found a special home.
The Brashear Telescope is one of the world’s most famous Victorian telescopes. The 18-inch refractor was created in 1894 by renowned Pennsylvanian Optician, John Brashear, and was fitted in an eight-metre long tube atop a 5.4-metre high pier and equatorial mount fabricated by the illustrious Warner & Swasey Co. of Cleveland, Ohio. The telescope was then installed in a ten-metre diameter dome at the Flower Observatory, owned by the University of Pennsylvania.
For over half a century, this extraordinary piece of equipment produced a multitude of valuable research data and became hugely important in the history of astronomy. During Percival Lowell’s studies of Mars, he famously used the telescope to see sunlight reflected off the Martian polar icecaps. The Brashear Telescope was also used by Walter Leight in his early examinations of Saturn, where Leight first observed sub-divisions in Saturn’s rings.
The Flower Observatory closed in 1954 and the Brashear Telescope was dismantled and placed into storage. In 1962, the University of Pennsylvania began exploring a Southern Hemisphere astronomy programme and so the telescope arrived in New Zealand and to Takapō in 1963 in a partnership with the University of Canterbury (UC). This partnership resulted in the establishment of the Mt John Observatory, but unfortunately for the Brashear, there were insufficient funds to build a dome suitable to house the nine-meter tall telescope and it was resigned again to life in storage.
In 2016, UC gifted the telescope to the Tomorrow’s Skies Charitable Trust to enable the long-held dream of restoration to be realised. It would also be part of a wider community outreach programme developed and executed by the Dark Sky Project team.
The Brashear Telescope is on display in Dark Sky Project Base at 1 Motuariki Lane, Takapō. All visitors can view the impressive telescope when they visit, and the Dark Sky Experience includes the ability to get up even closer and learn more with a guided tour.
