About the Planetarium

The Planetarium

The Palomar College Planetarium is the second planetarium for Palomar College.  The original planetarium was built in 1965 and served the campus for 43 years.  In July of 2008 it was demolished to make way for new campus construction.  Construction for the new planetarium was completed in March 2012 and it is currently one of the largest in California.  It opened its doors to the public on April 20th, 2012.

The Theater

The planetarium theater has 138 seats that sit under a 50-foot Astrotec dome.  The dome has a 15 degree forward tilt and consists of 42 perforated aluminum panels held in place by an outer aluminum structure.  The interior of the dome is painted with a highly reflective paint.

Each seat tilts back slightly and has a folding tablet arm for student use.  The theater can accommodate up to 4 wheelchairs at any one time.

Digistar 7 Presentation Technology

The planetarium presentations are largely driven by the Digistar 7 system manufactured by Evans & Sutherland.  To produce the fulldome images on the dome, two JVC digital projectors equipped with wide angle lenses work together to create one image.  Each projector provides 5000 lumens and produces a 4096 x 2048 display - together the image on the dome is 4096 x 4096 (4K) in size.

3 computers drive the display:

  • 2 computers act as graphics processors - each producing 1/2 of the display
  • 1 computer is the host

In addition to the Digistar 7 system, the planetarium is equipped with at Panasonic digital projector for presentations that do not require the D7 system.

The audio system is a 5.1 surround sound system that uses 8 speakers located outside of the dome to provide a rich ambient sound using 11,000 watts of power.

The Production Studio

The planetarium has a full production studio consisting of an editing room and recording room.  A Digistar 7 producer station allows planetarium staff to produce and render shows without using the resources of the Digistar 7 system that runs in the theater.

The images below are taken from inside the theater showing the Digistar 7 display on the dome.
