How does your Digitarium Gamma 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. (LTI will not allow any of our staff to see their system.) The Digital Starlab: • runs commercial planetarium software (Starry Night Small Dome) which includes comets, artificial satellites, more deep space objects, a larger catalog of dim stars, star proper motion, and can show views outside the solar system. • has a slightly higher resolution (1080 pixel diameter projection circle versus 1050). • has a higher claimed contrast ratio. • Has a base projector brightness (without fisheye lens) of 1000 lumens • has “spherical” pixels (to quote a 2007 press release). Each square pixel is blurred into more of a circular shape. • is warranted for one year (three years for the laptop). • takes up more space in the dome (at least twice as much). • “most likely” requires purchasing hardware upgrades in order to purchase software upgrades. • costs $7,400 US more.
