Quote: Now here’s a neat use of Canon’s lenses: the University of Toronto owns one of the smallest professional astronomical telescopes in the world that uses an array of photographic camera lenses instead of a single lens. Called the Dragonfly Telephoto Array, it uses ten ordinary Canon 400mm f/2.8L IS II lenses that cost $9,999 each. That’s $100,000 in photo gear.
I just ran into another item about a similar scope - well, actually there are two of them, using 8-200/f1.8 lenses for planet hunting.
