The Digitarium Delta 3 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 3 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.


  • Demonstrate beginning through advanced astronomy concepts.
  • Simulate the sky from any point on Earth or from other planets and moons.
  • Move forward or backward in time at varying speeds.
  • Simulate the solar system over a two million year time range.
  • Show the effects of precession of the equinoxes and star proper motion over time.
  • Show annual motion, including retrograde planetary motion.
  • Simulate celestial phenomena such as transits, eclipses, and meteor showers.
  • Display orbits of the planets and moons.
  • Display paths of solar system bodies against the stars.
  • Display ecliptic, celestial equator, meridian, and equatorial and azimuthal grids.
  • Show the entire celestial sphere with ONE piece of equipment.
  • Experience atmospheric effects, such as sunsets or a blue sky (or turn off the atmosphere to view the stars during the day).
  • Zoom in on or label items of interest.
  • View astrophotos of more than 100 deep space objects in situ.
  • Show constellation outlines, names, and artwork one at a time, a few at a time, or all at once.
  • Show constellations from multiple cultures (Western, Polynesian, Chinese, Navajo, ancient Egyptian, Lakota, Inuit, Inca, and more).
  • Label the sky in approximately 70 different languages.
  • Easily project your own image or video content using a USB drive or the internal hard drive.
  • Use the video-in port to project other applications from a separate computer, if desired.
  • Play fulldome video shows with 5.1 channel surround sound support.
  • Use the powerful scripting feature to create your own shows, short segments, or special effects.
  • Easy, automated software upgrades over the Internet keep you up to date with the latest features. Software updates are included free for the life of the system.


  • One projector does it all. No need for constellation projectors, slide projectors, multiple cylinders, etc.
  • Remote control with backlit buttons works from anywhere in the dome. No need to hover over the projector and block your audience's view.

Quick and Easy

  • Our unique backlit handheld remote control is the easiest interface to learn and use. No separate computer or extensive training is required.
  • Plug it in, turn it on, and you're ready to project in about one minute.
  • Start up to your default settings for latitude, longitude, sky time, and more.
  • Automatic positioning and phasing of celestial objects.
  • It's so straightforward, you don't need to be an astronomer to run it!


  • Low maintenance.
  • No laptops to overheat or break
  • Three year limited warranty on all components except the DLP projection component, which is warranted through the original manufacturer (see specific models for details).
  • Countdown of projector bulb life helps avoid the surprise of a burned out bulb.

Cost Effective

  • Modern fixed planetarium features at a fraction of the typical cost.
  • Opportunity to generate extra revenue introducing the Digitarium to other interested organizations through our Customer Referral Program.
Maximum Dome DiameterApproximately 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.

Pixels per degree of sky6 average
Angle of Projection~175 degrees
Base Projector Brightness4000 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 RatioUp to 50,000:1 (per projector specifications, without fisheye lens)
Lamp lifeUp to 3000 hours.
