The projection of the starry sky is what a planetarium is all about. Whether the artificial stars can fascinate and inspire hinges on the quality of imaging. ZEISS has set the standards for realistic and brilliant stars on the planetarium dome since 1923. In the age of digital video projection, more than ever before, it’s true that bright and point-shaped stars on a black, velvety background can only be produced with optical projection.
Thanks to LEDs, the stars are not only three times as bright as before, but also pure white compared to a slightly reddish hue of halogen-lit stars.
Introducing LED illumination, ZEISS sticks to its concept of a realistic simulation of the night sky. The number of stars of the northern and southern skies
projected remains approximately 7 000 – the quantity which a human eye can perceive under premium conditions, and which will not overload the view of the heavens in a planetarium of small or medium dome size. The brightest stars shine with their natural colors; faint objects are represented as far as the naked eye could see their natural counterparts, and the Milky Way is realistically simulated by optical projection.
