KStars lets you explore the night sky from the comfort of your computer chair. It provides an accurate graphical representation of the night sky for any date, from any location on Earth. The display includes 40,000 stars to 8th magnitude (well below the naked-eye limit), 10,000 deep-sky objects (Messier, NGC and IC catalogs), all planets, the Sun and Moon, the Milky Way, and guide lines such as the celestial equator, horizon and ecliptic.
Please report bugs or feature requests to the KStars development mailing list: <kstars-devel@lists.sourceforge.net>. You can also use the automated bug reporting tool, accessible from the Help menu.
