Digitarium Alpha 2+ Portable Digital Planetarium System
This model has been discontinued. Please see our
current models.
Product Overview
The
Digitarium Alpha 2+ Portable model is a great option for portable venues
where either the higher brightness or better projection quality is desired but
higher resolution
Digitarium models are out of your budget. For portable
use we generally recommend the smaller, lighter weight, and less expensive
Digitarium Alpha 2 Portable model.
Maximum Dome Diameter
|
Approximately 56 feet/17 meters. Brightness
is the main
issue, since the larger the dome,
the larger the surface area the light from the projector must cover.

180 degrees, full sky.

4.3 average

|
175 degrees
|
Base Projector Brightness
|
6500 Lumens with both lamps and a 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.)

Contrast Ratio
|
Approximately 1200:1
|
Lamp life
|
2000 hours
The projector has two lamps which can be used one at a time, or both together for the brightest projection.
