At Keck we use the graphical tool sky to plan observations and to control the telescope. Since 1992, sky has provided all status via alphanumerics and control via buttons. We recently extended sky to provide status via a graphical star field. The user controls the telescope by clicking on stars and an overlayed view of the instrument detectors. Geometrical operations, painful to convey in the alphanumeric sky, become trivial using the graphical approach. In this paper we discuss the advantages of the new display.
