Digitarium® Delta 4 Digital Planetarium System
This model is discontinued. View current portable models.
The Digitarium Delta 4 is our entry level planetarium system, designed to be easy to transport, set up, and teach with. It projects high contrast 1080 pixel diameter imagery over a full dome with no blind spots or cut-outs. It is the culmination of years of development effort, with our own innovative proprietary lens design.
The Digitarium Delta 4 offers not just a compact size but quick set up, intuitive user interfaces, high resolution, excellent projection quality, and wealth of other features. Digitalis sells inflatable domes in several diameters for a complete portable solution.

Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
