Nightfall 1.86

Nightfall is an astronomy application for science, education, and fun. It can produce animated views of eclipsing binary stars, calculate synthetic lightcurves and radial velocity curves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system. Nightfall comes with a user guide, and a set of observational data for several eclipsing binary star systems.

Sky Chart 3.11

SkyChart draws an observable night sky of stars and nebulas from its catalog. It can also note the position planets, comets or asteroids. Many parameters allow automatic catalog selection, adapting colorization and dimensions, labels for non-star objects.
