Product Overview

The Digitarium® Kappa Portable 2 model is a digital planetarium system designed for use in portable domes.

This model is designed for those who want the highest resolution and best projection quality in a portable Digitarium system. The Kappa's high resolution is invaluable if you show fulldome video shows, immersive environments, or scientific visualizations. Starfields will also look better, especially with the high contrast and our high quality proprietary lens.

The Kappa includes our high-resolution data sets of the Earth and solar system for spectacular planetary exploration with incredible detail.
