A modified Fairchild CCD-221 detector has been installed in the coude spectrograph of the KPNO 2.1-m telescope for use in obtaining high dispersion stellar spectra. The system can be used to obtain spectra in the wavelength region from 4900 - 9900 A with resolutions ranging from 70 - 470 mA. The instrument system features a newly designed "universal" dewar, which may be used to mount the CCD in most any orientation, and an integrated observing and data reduction software system, which automates most of the routine data processing steps.
