How does your Digitarium Gamma or Epsilon Portable compare to the Digital Starlab projector?
Based on publicly available information, these are the most important differences that we see between these two systems. (Science First will not allow any of our staff to see their system.) The Digital Starlab: • runs third-party commercial planetarium software (Starry Night Small Dome) which includes more deep space objects, a larger catalog of dim stars, star proper motion, and can show views outside the solar system. Licensed for one computer only. • has a slightly higher resolution than the Digitarium Gamma (1080 pixel diameter projection circle versus 1050). • has a lower resolution than the Digitarium Epsilon (1080 pixel diameter projection circle versus 1200). • has a higher claimed contrast ratio (we suspect they have never measured the actual contrast with their own lens in place). • has a base projector brightness (without fisheye lens) of only 1000 lumens. • is warranted for only one year (three years for the laptop). • takes up more space in the dome (at least twice as much
