Full featured planetarium software. Plot the positions of the Sun, Moon, and planets, comets and asteroids (download the latest data sets from the Internet), 2.5 million stars, and more than 13,000 deep-sky objects. Maps can be displayed in color (including "true sky" view), black and white, and night-vision-preserving red. Adjust chart colors and fonts to your liking and then print the maps to use outside. The program will calculate ephemerides for solar-system objects and plot trailed paths for these bodies through the sky. Also many deep-sky object images are included.
