Digitarium Gamma Fixed Digital Planetarium System

Product Overview

The Digitarium Gamma Fixed model is a digital planetarium system designed for use in permanent domes. It is very similar to the Digitarium Alpha 2+ Fixed model, but offers higher resolution (about 87% more pixels) and a slightly brighter projector. 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, the best projection quality, and either can not afford a higher resolution Digitarium system or desire the wide projection angle of 175 degrees. It is also our brightest option for fixed domes.

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 and brightness!
