Abstract

Observations made with an RCA thinned back illuminated CCD on the echelle spectrograph of the Kitt Peak 4-meter Mayall telescope are discussed. With emphasis on interstellar line measurements in bright and faint background sources, the system efficiency, spectrum format, achieved signal-to-noise, interference fringes, and overall performance are discussed. A signal-to-noise of > 100/1 has been achieved at 0.2 Å resolution in two hours on a 13.2 mag star. Projected CCD improvements should yield signal-to-noise ratios of 20/1 for 18th magnitude objects (V) in 2 hours. With appropriate gratings, 1500 Å of continuous spectrum can be obtained.
