Digitarium® Delta 2 Digital Planetarium System
The Digitarium® Delta 2 is an extremely affordable, high resolution digital planetarium system ideal for portable or small fixed domes. It projects a 1080 pixel diameter circle over a full dome with no blind spots or cutouts. It is the culmination of years of development effort, with an innovative proprietary lens design.
The Digitarium Delta 2 offers a compact size, quick set up, intuitive interface, high resolution, and wealth of features at a surprisingly affordable price. Digitalis also sells inflatable domes in several diameters for a complete portable solution.
The Digitarium Delta 2 outperforms other low cost digital systems on the market, avoiding common drawbacks such as incomplete sky coverage, terrible focus, obvious distortions, difficult user interfaces, easily damaged components, unreliable software and/or hardware, and poor support.
Although more expensive than most portable analog ("pin-hole") projectors, we believe the Digitarium Delta 2 to be a huge value proposition: you receive the features of a modern digital planetarium at a fraction of the typical cost. Think of the power of a computer versus a slide projector.
Affordable and flexible, the Digitarium Delta 2 will revolutionize your astronomy teaching.

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

|Angle of Projection
|Base Projector Brightness
||4000 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. Please see any of our other models if you need a brighter system.)
|Nominal Contrast Ratio
||50,000:1 (per projector specifications, without fisheye lens)
||Up to 3000 hours
