The Dragonfly Telephoto Array is expanding to have 168 Canon 400mm f/2.8L IS USM II lenses pointed at the sky

by Leave a Comment

Project Dragonfly, designed by a team from Yale University and the University of Toronto in 2013 is an attempt to capture the darkest parts of the sky that are so faint that they’ve managed to escape the gaze of more conventional telescopes – even the really huge ones. The design was built using an array of 3 Canon EF 400mm f/2.8L IS USM II lenses to begin with in what they called the Dragonfly Telephoto Array.

It was expanded to 10 lenses and in 2015, Canon supplied 40 more EF 400mm f/2.8L IS USM II lenses to the team, bringing their total up to 48 in two 24-lens units. Now, with some more help from Canon, the team is going to put together four more of the Dragonfly Telephoto Array units for a total of 168 400mm f/2.8 lenses pointed towards the sky to capture the darkest galaxies in the universe.

NASA celebrates Hubble’s 30th birthday with this gorgeous image of starbirth

by 1 Comment

On 24 April 1990, the Hubble Space Telescope started its journey, when the space shuttle Discovery and its five-astronaut crew took it from NASA’s Kennedy Space Center in Florida. It was deployed into Earth orbit a day later and has been taking magnificent photos of space ever since. The photo Hubble took on its 30th birthday is nothing less impressive than others, and it shows the incredible beauty of starbirth.

The Dragonfly Telescope Uses Ten Canon 400mm f/2.8 Lenses to Detect Faint Galaxies

by 7 Comments

While telescopes do a great job gathering light and obtaining images of ridiculously distant objects, even the largest and most advanced units are assumed to be unable to detect certain faint structures due scattered light which may be hiding them.

An awkward looking, multi-lens array was built to solve the problem – the Dragonfly Telephoto Array. Using ten of Canon’s finest 400mm lenses, the Dragonfly’s design significantly reduces scattered light and internal reflections within the optics, allowing ultra-low surface brightness astronomy at visible wavelengths.
