Digitarium® Delta 4 Digital Planetarium System
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.

|Maximum Dome Diameter
||Approximately 24 feet/7 meters.
Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
|Projected Resolution||0.92 megapixels|
|Field of View||180 degrees, full sky.|
|Pixels per Degree of Sky
|Angle of Projection
|Base Projector Brightness
||4500 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 projector contrast is 6,000:1.|
||Up to 3,000 hours on high, 5,000 hours in eco mode.
|User Interfaces Included
||Stereo with external user supplied speakers.|
|Software||Nightshade NG Basic|
||100-240VAC, 50-60Hz, 450W|
