Digitarium Epsilon Portable Digital Planetarium System
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 the highest resolution and the best projection
quality in a portable Digitarium system. 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 48 feet/14.5m 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
|
5700 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 1700 hours on high/2200 hours on low
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.
