Demo Version Limitations

In order to maintain a reasonable size, this Demo version contains only a small subset of the astronomical databases available with the full version of Voyager 4. Here are the differences:

Feature	Demo Version	Full Version
Stars	26,799 (to mag. 7.5)	155 million (to mag. 18.0)
Deep Sky Objects	2,289 (to mag. 12.0)	1 million (to mag. 20.0)
Asteroids	11,974	396,583
Comet Orbits	362	3,109
Satellites & Spacecraft	644	849
Deep Sky Object Images	78	240
Solar System Object Images	19	34
Horizon Profile Images	3	6
Image Gallery Images	none	600

Several menu items in the "Tools" menu of the Demo version are disabled. These correspond to features which would not work properly with the limited Demo version database. Such menu items include the "Image Gallery", "Asteroid Survey", "Binary Star Orbits", "Star Survey", and "Redshift Distribution" commands. These items are all, of course, functional in the full version of the program.

In addition, the Demo version includes only low-resolution versions of the images used to render planets, moons, and deep sky objects. In the full version, the deep sky object images have twice the resolution; and for many solar system objects, the image resolution is four times as high. Here are some examples; you can click on the "preview" images below to see full-size images generated by the Demo and Full versions of the program.
