Hectochelle is a high-resolution, multiobject optical spectrograph fed by 240 optical fibers. It operates at the f/5 Cassegrain focus of the 6.7-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 240 optical fibers in just 5 minutes.
