We often featured the Canon ME20F-SH specialized camera, and wrote about the impressing low light…
We wrote about this project time ago. Now it evolved and we won’t miss the news.
The Dragonfly Telephoto Array belongs to the University of Toronto’s Dunlap Institute for Astronomy and Astrophysics. The ten EF 400mm f/2.8L IS II make up for approximately $100,000. The lenses were mounted on ten SBIG STF-8300M CCD cameras, and that makes up for another whooping $20,000. There is also a Paramount ME-II robotic telescope involved, which is yours for just $135,000.
What is the thing good for? Quoting:
Dragonfly is designed to reveal the faint structure [of the universe] by greatly reducing scattered light and internal reflections within its optics. It achieves this using ten, commercially available Canon 400mm lenses with unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses.
There are some research paper available if you are into this sort of scientific things:
- Forty-seven Milky Way-sized, Extremely Diffuse Galaxies in the Coma Cluster
- The discovery of seven extremely low surface brightness galaxies in the field of the nearby spiral galaxy M101
- First results from the Dragonfly Telephoto Array: the apparent lack of a stellar halo in the massive spiral galaxy M101
