Product Overview

The Digitarium® Epsilon Portable model is a digital planetarium system designed to be portable. This system can be used in either a full dome or a truncated projection mode. It is very similar to the Digitarium Gamma Portable model, but offers higher resolution (about 30% greater in full dome mode and 56% greater in truncated mode).

Full dome/full sky projection is available at a projection angle of 155 degrees. This is not ideal for the typical inflatable dome as the projection will be somewhat higher on the dome than a more immersive 175 degree projection. It is, however, a good solution if you want to use chair type seating, have a higher than typical dome springline, or need a moveable system for a fixed dome.

In truncated projection mode, a 1344 pixel diameter truncated circle (truncated to a 1920x1200 pixel frame) is projected at a 180x155 degree projection angle. This mode is typically best suited for high resolution wide angle immersive movie uses. The planetarium features will still work, but with part of the sky missing we don't recommend this mode for serious astronomy education.

The Digitarium Epsilon has the same unmatched usability of other Digitarium systems with our exclusive backlit, handheld remote control.

This model is designed for those who want high resolution and the best projection quality in a portable Digitarium system but can not afford the Digitarium Kappa Portable model. If you intend to show a lot of fulldome video shows, immersive environments, or scientific visualizations, the higher resolution will be invaluable. Starfields will also look better, especially with the high contrast and our high quality proprietary lens.

Despite all these features, the price is a fraction of other high quality full dome fisheye planetarium systems of similar resolutions!

Maximum Dome Diameter
Around 52 feet/16m in full dome projection mode. Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
Base Projector Brightness
7500 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
2200:1 measured
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.
Image Quality
Digitarium Epsilon systems use our most advanced proprietary lens design for the best projection quality available in Digitarium systems.
