A home-brew observatory detects exoplanet

David Schneider, a senior editor at IEEE Spectrum, was interested in exoplanets, planets that orbit stars other than the sun, but figured this kind of exercise as a home-based project was going to need expensive telescopes; he stumbled across a project at Ohio State University, where resourceful astronomers had figured out a way to spot exoplanets using a device with a lens designed for high-end cameras. Schneider's wheels turned, thinking he might also be able to pull this off if he got his han
