How does a Digitarium system compare to an analog Starlab projector?
The digital technology used in a Digitarium system offers many advantages over portable analog (pinhole) systems like Starlab. For example: • A Digitarium system can demonstrate annual motion, including retrograde planetary motion. You can even turn on planet trails to make it easy to see the paths of the planets as viewed from Earth. Portable analog projectors like Starlab are by design limited to daily motion; the sun, planets, and moon cannot move independently of the stars once you set them up. • A Digitarium system automatically and exactly positions all celestial objects for you. Starlab users can only approximate planet and lunar positions using a system of mirrors and magnets. • A Digitarium system’s software accounts for precession of the equinoxes. • Almost no formal training is required with a Digitarium system. The system is operated via a handheld remote control with backlit buttons; icons on the buttons help you remember the function of each. You can teach yourself astron
