An automated fiber optics manipulator that allows the acquisition of up to 10 spectra simultaneously with an existing long slit spectrograph has been placed in operation at the Michigan-Dartmouth-MIT Observatory. Pickoff optics that view mirrors at the fiber probe tips allow visual alignment of the probes on the target objects. This feature eliminates the requirement for subarcsecond astrometry, careful focal plane calibration and highly precise actuator motion.
