Equinox is a powerful planetarium program that has many features for both the beginner and advanced astronomer. It has filters for organizing deep sky objects with many controls to adjust the sky display, colors and fonts. Equinox can control most telescopes and there is a window that simulates a telescope's view. You can build tours and photo horizons and modify the database. You can even slew your telescope with voice commands.

World Book's translucent 3D globe utilizes satellite photography to give you an astronaut's-eye view of Earth and let you quickly find the distance between any two cities. Just enter your starting and ending points ― the Distance Calculator plots them on both a three-dimensional globe and a flat map and displays the distance. The Distance Calculator can also determine how far it is between a set location and the location indicated by your pointer, or between any two locations you click on the map.
