is the main
issue, since the larger the dome,
the larger the surface area the light from the projector must cover.
||1080 pixels across a diameter
|Field of view
||180 degrees, full sky.
|Pixels per degree of sky
|Angle of Projection
|Base Projector Brightness
||2200 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 our other models if you need a brighter system.)
||3900:1 (Actual measured value with fisheye lens.)
||Up to 3000 hours
||Good, although focus is not as sharp as our Gamma and Epsilon models.
This is a tradeoff in the interest of an affordable system.

In July, our first Beginners' Session using the [Digitarium Alpha] planetarium was a big hit -- it was hard to get people to go outside and look at the REAL stars, although it was a beautiful night.
