Planetarium Director

At OBU I supervised the design and installation of a uniquely designed planetarium and multimedia theater, implemented with an academic mission for undergraduate liberal arts education.

    (PowerPoint 98, 12 MB)

The planetarium now plays a central role in science courses for liberal arts majors as a setting for instruction in the historical development of astronomy and cosmology.

Responsibilities as Director included:
  • GNSC 250 Planetarium Operations
  • Labs for US 311 Natural Sciences
  • Supervising 10-12 planetarium student workers.
  • all aspects of maintenance and technical operation
  • program production and show presentation for:
    • university classes
    • university guests, including visiting alumni and prospective students
    • school groups (Thursdays and Fridays)
    • weekly public shows (Friday nights)

[Small Logo]A planetarium is a room with a dome-shaped ceiling. At the center of the room is a star projector, which projects points of light representing the stars and planets onto the dome to simulate the night sky for any time of night, any day of the year.

Many people confuse planetariums and observatories: the latter are dome-shaped houses that contain telescopes for observing the skies. Many planetariums do have telescopes and sponsor star-gazing parties, but the essential feature of a planetarium is the star projector, not the telescope.
