Planet Discovered Using Telephoto Camera Lenses

[rvr] writes "The Space Telescope Science Institute (STScI) reports the discovery of an extra-solar planet called XO-1b, which orbits a dim star in Corona Borealis every 4 days. To find it, the brightness of several thousand stars were regularly scanned using two mini-telescopes in Hawaii. This equipment was built using commercial hardware: two digital cameras, attached to telephoto camera lenses on a robotic equatorial mount. A team of amateur astronomers helped with their own equipment to discard or confirm dozens of suspected transits."

Real ingenuity

That's real ingenuity and intelligence: not throwing money at getting incredible machines to do things for you, but working out what you can do with off-the-shelf stuff and designing a system around it. People have already spent a lot on big telescopes for extrasolar planet hunting.
