The nifty record feature is somewhat hampered by the dark interface. The controls live in the lower left corner and are transparent-a bit hard to find. Stellarium incorporates star-views from the Moon. Besides equatorial and azimuthal grids, users also get shooting stars when appropriate, eclipse simulation, and skinnable landscapes.

The constellations of 10 different cultures are included, as well as illustrations and asterisms to help you visualize what the ancients saw. The default catalog includes 600,000 stars, with upgrade modules that can push the count up to 210 million stars.
