xsky is an X Window System program which is essentially an interactive sky atlas. The familiar actions of scrollbars, sliders, and pointer gestures such as clicking and rubberbanding can be used to move around the sky, adjust the magnification, select a region to view, and bring up detailed catalog information on any object. Objects can be located by name or position, and labelled with either catalog labels or custom user labels.

Stars are plotted with colors corresponding to spectral class, and size corresponding to apparent magnitude. Non-stellar objects are drawn in several shapes according to the type of object represented. Right ascension and declination lines can be generated, and constellation boundaries are available. A PostScript file containing all this information can be generated for printing. For a complete exposition of xsky's capabilities, please see the SUMMARY file in the distribution.
