Digitarium® Alpha 2 Fixed Digital Planetarium System
This model has been discontinued. Please see our current models.
Product Overview
The Digitarium® Alpha 2 Fixed model is a digital planetarium system designed for permanent installation in fixed domes up to 33 feet/10 meters in diameter with a limited budget.
If possible, we recommend purchasing the Digitarium Alpha 2+ Fixed instead, due to the better projection quality.
Note that the Digitarium Alpha 2 and 2+ Fixed models look almost identical externally.
Specifications

| Maximum Dome Diameter |
Approximately 33 feet/10 meters. Brightness
is the main
issue, since the larger the dome,
the larger the surface area the light from the projector must cover. |
| Resolution |
768 pixels across a diameter |
| Field of view |
180 degrees, full sky. |
| Pixels per degree of sky |
4.3 average |
| Angle of Projection |
175 degrees |
| Base Projector Brightness |
4000 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 contact us if you may be interested in a brighter system.) |
| Contrast Ratio |
Approximately 900:1 |
| Lamp life |
3000 hours The projector has two lamps which can be used one at a time, or both together for the brightest projection. |
| Image Quality |
Some violet color separation is present, however we do not believe that this will distract from your teaching. This is a tradeoff in the interest of an affordable system and has been
improved from the previous model.
