Hectospec is a moderate-resolution, multiobject optical spectrograph fed by 300 optical fibers. It operates at the f/5 Cassegrain focus of the 6.5-meter MMT on Mount Hopkins in Arizona. The instrument is composed of a robotic positioner and a large, bench-mounted spectrograph, joined by a bundle of 25m long optical fibers. Dual robots, dubbed Fred and Ginger, reconfigure all 300 optical fibers in just 300 seconds.
