Digitarium Epsilon (fixed version)

Digitarium Epsilon Fixed Digital Planetarium

The Digitarium Epsilon Fixed model is a digital planetarium system designed for use in permanent domes. This system can be used in either a full dome or a truncated projection mode. It is very similar to the Digitarium Gamma Fixed 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 ideal for fixed domes, as the projection system is placed below the springline of the dome out of audience sight lines.

In truncated projection mode, a 1344 pixel diameter truncated circle is projected at a 180x155 degree projection angle. This mode is typically best suited for high resolution wide angle immersive movie uses with unidirectional seating. For astronomy and planetarium works Digitarium Epsilon can project a 360° degrees full sky not truncated at a 1200 pixel resolution, the highest in this price range. Epsilon so permits to have two projection resolutions: 1200px full sky or 1344 truncated depending of the use and needs.

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

The Digitarium Epsilon Fixed model is designed for those who want the highest resolution and the best projection quality in a fixed 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!
