Paper Abstract

The converted 6.5m MMT Observatory has a powerful suite of new instrumentation accumulated over the last eight years. Pre-conversion instruments still in use at the f/9 Cassegrain focus are the facility Red and Blue Channel spectrographs (R = 240 - 6600) and the visiting spectropolarimeter (SPOL). Instruments using the f/5 spectroscopic configuration are the bench mounted 300-fiber spectrographs Hectospec (R=1000) and Hectochelle (R=30,000), and the single slit, cross-dispersed spectrograph MAESTRO (R=28,000 - 93,000). The f/5 imaging configuration offers Megacam, a 24' x 24' CCD mosaic camera and SWIRC, a YJH NIR imager. The MMT's pioneering f/15 adaptive secondary mirror enables high-resolution imaging and spectroscopy in the infrared with the ARIES, CLIO, PISCES and BLINC/MIRAC instruments. The AO system will shortly be significantly enhanced with the addition of a Rayleigh laser guide star system which is currently being commissioned. Upcoming instrumentation will include slit mask spectrographs in the infrared (MMIRS) and optical (BINOSPEC). This review paper presents all the available instruments capabilities and demonstrates how the observatory has become highly efficient at managing multiple secondary mirrors and a large instrument suite.
