TheSky combines speed and accuracy with an easy-to-use interface. This full-featured program (Level IV, Version 5) includes a desktop planetarium that can simulate the sky from any location on any date and map objects from numerous catalogs. The daytime mode lets you view beautiful sunsets, and you can animate solar-system objects and view eclipses and occultations. Works seamlessly with the RealSky CD-ROMs to overlay charts on images.
