Product Overview

The Digitarium® Zeta Portable model is a digital planetarium system designed for use in portable domes. Set up the system in a gym with an inflatable dome for an instant planetarium. Portability and ease of set up and use allow you to share one system and its cost with other area groups.

This model is designed for those who want a mid-range resolution portable system with mid-range brightness.

Choose from a lighter and lower cost Basic option or a more powerful and upgradeable Professional computer/software combination. See specifications below for details.
