The Michigan Infrared Beam Combiner (MIRC) has provided the first images ever obtained for a main sequence star other than the sun. This instrument, which combines light from up to six CHARA telescopes simultaneously, was developed by John Monnier and his optical interferometry group in the Astronomy Department of the University of Michigan.
