|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.
||768 pixels across a diameter
|Field of view
||180 degrees, full sky.
|Pixels per degree of sky
|Angle of Projection
|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.)
The projector has two lamps which can be used one at a time, or both together for the brightest projection.
||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.

We are all absolutely delighted with our new Digitarium Kappa system! The system is reliable and very easy to use and the graphics are superb. It was a joy to work with the people at Digitalis!
