15 Best Free Star Tracker Software For Windows

This is a list of best free star tracker software for Windows. These software help to locate stars in the space, and provide their exact coordinates (in any of the supported celestial coordinate system). Also, you can have information about deep space objects, planets, comets, solar system, and galaxies. You can have information about their type, constellation, coordinates, right ascension (RA), declination, azimuth, altitude, etc. They also point out magnitude, color index, distance from earth, parallax, mean/apparent sidereal time, etc. information about the selected star.

Almost all these star tracking software provide space view with many types of grids. In most of them, you will get equatorial, horizontal, elliptic, etc. grids. Many of them even provide you guided tours to the star, planet, and other celestial elements. Also, you can run animation of movement of space elements with adjustable time (past/future) and speed. All in all, these software provide high quality imagery of the universe.

If you want to save the sky map, many of them provide this feature also.
