cs12 (Long focus camera) - A moderate to very-high resolution spectrometer
used with TK4
CCD as the detector. The maximum demonstrated resolving power is 600,000.
The plate scale is 2.3 arcsec/mm. Five gratings and two echelles are available
to provide a variety of resolutions and wavelength coverage from 0.3 to
1.2 microns. Noiseless coaddition on-chip is available for lower spectral
and spatial resolutions. Autoguiding is available.
