Ideal for outreach, the world's smallest turnkey digital planetarium system!

Product Overview

Digitarium Iota

Extremely compact, lightweight, and powerful, the Digitarium Iota (pronounced eye-OH-ta) makes it easier than ever for one person to transport, set up, and teach with a high resolution portable digital planetarium system. Never before has a complete system been this small or powerful.

The Digitarium Iota projects over a full dome with no blind spots or cutouts. It is the culmination of years of development effort, with our own innovative proprietary lens design.

The Digitarium Iota offers not just a compact size but quick set up, intuitive user interfaces, high resolution, excellent projection quality, and wealth of other features. Digitalis sells inflatable domes in several diameters for a complete portable solution.

Choose from a lower cost Basic option or much more powerful Professional software package. See specifications below for details.
