Inside the 250-squarefoot control room, graduate student Arne Henden prepares to make remote adjustments to a telescope accessory. The left television monitor in the console in front of him shows the star field or spectrograph slit as viewed by the vidicon guider. The monitor at right displays the telescope's pointing direction and other observing information. At far right in this scene are electronics racks containing the microcomputer and multichannel-analyzer data-acquisition system for the spectrograph.
