Product Overview

The Digitarium Gamma Portable model is a digital planetarium system designed for use in portable domes. It is very similar to the Digitarium Alpha 2+ Portable 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 relatively high resolution, the best projection quality in a portable Digitarium system, and highly immersive projection (175 degree projection angle). 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 enhanced 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!
