Ideal for Outreach, The World's Smallest Turnkey Digital Planetarium System!

Now with new, lower pricing: the Iota has never been a better value!

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 a 1200 pixel diameter circle 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 more powerful Professional software package. See specifications below for details.

Maximum Dome Diameter
Approximately 20 feet/6 meters.
Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
1200 pixels across a diameter
Field of view
180 degrees, full sky.
Pixels per degree of sky
6.7 average
Angle of Projection
Typically ~175 degrees. User can zoom to as little as 122 degrees for special situations.
Base Projector Brightness
3000 Lumens with non-fisheye lens
(Provided for comparison purposes with other systems. Actual brightness with a fisheye lens is significantly less due to not projecting the whole video rectangle and differing lens properties. Please see any of our other models if you need a brighter system.)
Nominal Contrast Ratio
Up to 2500:1 (per projector specifications, without fisheye lens)
Lamp life
Up to 2250 hours on high, 3000 hours in eco mode.
