Product Overview

The Digitarium® Gamma Portable model is a digital planetarium system designed for use in portable domes. It has the same unmatched usability of other Digitarium systems with our exclusive backlit, handheld remote control.

This model is designed for those who want a relatively high resolution system but need high brightness for a larger dome or more vivid colors. This is our brightest option for portable domes.

Maximum Dome Diameter
Around 60 feet/18m. Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
Pixel Diameter
Projected Resolution
0.87 megapixels
Field of view
180 degrees, full sky.
Pixels per degree of sky
5.8 average
Angle of Projection
175 degrees
Base Projector Brightness
8000 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.)
Contrast Ratio
Nominal projector contrast of up to 7,500:1.
Lamp life
Up to 2000 hours on high
The projector has two lamps which can be used one at a time, or both together for the brightest projection.
Internal Storage
1 TB expandable up to 8 TB or more.
