It is being used in planetarium projectors. Just set your coordinates and go. Default catalogue of over 600 000 stars, extra catalogues with more than 210 million stars! Asterisms and illustrations of the constellations. The planets and their satellites. Star twinkling, shooting stars, eclipse simulation. Very realistic atmosphere, sunrise and sunset.
