There are 88 official constellations defined by the International Astronomical Union, although how the stars are joined to form the patterns is somewhat open to interpretation. From the display list individual constellations can be selected or deselected. Show menu allows you to select all or none visible or toggle the display of Northern, Southern, Visible (in the sky) and Zodiac constellations. Press the column headings to sort.

From the View menu constellation names and zodiac symbols can be selected for display. The file options allows you to select the constellation file (see files).
