The mysteries of the night sky are revealed with Star Seeker, an easy to follow introduction to the fascinating science of Astronomy.

Star Seeker accurately plots on-screen the position of more than 300 of the most prominent stars in the night sky. It will map the sky from any point on Earth at any day and time in this and the next century.

A host of features include options to name and plot constellations, to simulate the changing night sky as the Earth rotates, and to pinpoint individual stars for on-screen information including their accurate positions.

Also included is a companion program Solar System which locates the planets in the sky and plots their orbits relative to the sun and each other. Solar System also plots the course of Halley's Comet, last seen in 1910 and due in our skies in 1985 and 1986.

An informative instruction booklet explains how to operate the programs and provides a wealth of astronomical information.
