2.2 Front Slit Viewer

Front slit viewing is available at all times and is used for acquisition of the object and guide stars. While an eyepiece is available for direct viewing, the usual mode is with an ICCD TV monitored in the console room. This arrangement yields a 75 x 100 arc-sec field. Stars as faint as about V = 19.5 are visible on the TV with the leaky memory during dark time with 1" seeing.
