The oldest starball in the USA gets a modern companion from ZEISS
ZEISS VELVET LED for Springfield Science Museum
Jena, Germany / Springfield, Massachusetts, USA | 03 May 2023 | ZEISS Planetariums
Since the opening of the Seymour Planetarium at the Springfield Science Museum 86 years ago, the same starball has always been used to simulate the starry sky. The projector, which was specially constructed by the Korkosz brothers for the Seymour Planetarium, is now considered the oldest working planetarium projector in the USA.
Now the planetarium has been upgraded for the 21st century and will be able to present digital fulldome content to audiences thanks to the new VELVET LED projectors from ZEISS. However, the Korkosz Starball will continue to fill the dome with stars and constellations as it has since 1937.
The fact that Korkosz and Zeiss projectors will operate under the same dome is a successful marriage of old and new. The installation of the new Zeiss full-dome projection system represents the final phase of a major upgrade initiated several years ago by former Science Museum Director Mike Kerr. That project has now been successfully completed under the direction of current museum director Jenny Powers.
"Springfield's historic Korkosz Starball is the most famous optomechanical planetarium projector in the United States," says Howard George, projection systems engineer at Seiler Instrument & Manufacturing Co. in St. Louis. George installed the new Zeiss projection system with Zeiss planetarium technicians from Jena, Germany.
The first public demonstrations of the new projection system from ZEISS were presented to the public during the Astronomy Day celebration at the Museum of Science on April 29.
