What is a Planetarium?

  • A Planetarium theater is a special room with a dome shaped ceiling and a projector in the center which can recreate the day or night sky by projecting images of the stars, planets, the sun, the moon, and more. The Digistar 6 software can be set to show the sky for any date, time, or latitude. Without leaving your seats, you will be transported beyond the city smoke and lights where the wonders of the heavens can best be seen.
