Product Overview

The Digitarium® Zeta Fixed model is a digital planetarium system designed for permanent installation in fixed domes up to 40 feet/12 meters in diameter.

This model is a good fit for those who want an affordable high resolution fixed system but can do without the special fixed dome features of our Digitarium Epsilon Fixed or Digitarium Kappa Fixed models. The Zeta can block more audience sight lines due to its larger projection angle, and it is limited to smaller domes.
