Stellarium - is a comprehensive utility that helps users explore planets and constellations in a 3D environment. This open-source planetarium gives you details about celestial objects, simulates solar and lunar eclipses, and displays Messier objects and the Milky Way. Features • Over 120000 stars from the Hipparcos Catalogue with name and infos for the brightest ones. • Planets and major satellites in real time (position computation now accurate enough for eclipse or transit simulation). • Drawing of the 88 constellations with their names. • Mythological figures of the 88 constellations. • Textured displaying of more than 70 nebulas (Orion, M31 etc..). • Photo-realistic Milky Way. • Star twinkling. • Shooting Stars. • Skinable landscape (ground, fog, mapping of fisheye pictures). • Ultra fast realistic atmosphere rendering (Sunsets, sunrises etc...). • Automatic eye adaptation to sky luminance using physiologic model. • Grids in Equatorial and Azimuthal coordinates. • Equator and ecliptic coordinates lines. • Smooth real time intuitive navigation. • Powerfull zoom to see planet and nebula like in a telescope. • Equatorial and altazimutal mount mode. • Standard perspective and wide angle (fisheye) projections modes (e.g for planetarium dome). • Time control (real time and accelered time modes). • Graphical menu for simple utilisation. • Clikable stars, planets and nebulas with informations. • Windowed and fullscreen modes. • Full dome (180?) projection mode for planetariums. • Text user interface for planetariums.
