The planetarium at Seoul Science Park in South Korea opens on 21 April 2023 with new ZEISS technology. The hybrid planetarium system for the 11-m dome combines an opto-mechanical star projector and digital projection technology controlled by ZEISS UNIVIEW software. It uses the ZEISS ASTERION Starball, the latest version of star projector from ZEISS, as an analog component for impressive, near-natural depiction of the starry night sky. Two ZEISS VELVET LED projectors complement the hybrid system with digital 360-degree fulldome projection.

The ZEISS ASTERION Starball for Seoul is a new development from ZEISS: it was expanded for the Korean customer to include a lift for lowering the Starball from the center of the dome and equipped with a scintillation device, which causes all stars to twinkle in response to a control command, just as they do in nature by force of atmospheric influences.

Both ZEISS ASTERION and ZEISS VELVET projection provide a deep black background without the characteristic glow caused by other digital projectors. The Starball replaced the 30-year-old ZEISS M1015 star projector.

The vice president of Seoul Science Park, Deuk-Sil Jeong, is very pleased with the ZEISS hybrid planetarium: “With the new planetarium technology, visitors to the planetarium at Seoul Science Park can enjoy a ‘perfect’ night,” he explains. “The ZEISS UNIVIEW planetarium software offers accurate and vivid astronomical visualizations. It allows all phenomena of the universe to be displayed in a three-dimensional and immersive perspective beyond the earthbound view, all the way out to the remnants of the Big Bang.”
