Planetarium Projector – For Portable Domes
Astronomy outreach programs
finally have an affordable option for a full-featured
planetarium projector: the Digitarium Alpha.
The Digitarium Alpha, created by Digitalis Education
Solutions, is a digital planetarium projector designed
specifically for portable domes. It provides an unmatched
combination of price and performance, allowing education
outreach programs to take the capabilities of a fixed
planetarium on the road.
This revolutionary new projector allows any outreach program
to upgrade to full-featured equipment. All the features of
fixed planetarium projectors are here: annual motion;
projection of the entire celestial sphere, including the
Milky Way; exact latitude, longitude, and date setting;
celestial reference lines and grids; and more.
Unlike traditional starballs, users can easily show
constellation line drawings and art, label objects of
interest, and zoom in on any object for a closer look-with
just one piece of equipment. Zooming in on Jupiter, for
example, one can watch the Galilean moons orbit. Users can
then zoom in further on each Galilean moon for more detail,
if desired. There are about 100 images of actual deep space
objects that can be labeled in the sky and magnified. All
this from a projector that weighs under 35 pounds, and is
approximately 14 inches in each dimension. A remote control
with back lit buttons makes it easy to operate the projector
from anywhere inside the dome.
Set up is as easy as plugging it in and turning it on. The
projector starts up in just over one minute to the user's
default settings for latitude, longitude, sky time, and
more. Stars, planets, the moon, and other objects are
positioned automatically, saving valuable time. It's so
straightforward you don't need to be an astronomer to run
At $13,900, the Digitarium Alpha is the first planetarium
projector-fixed or portable-capable of demonstrating annual
motion for less than approximately $60,000. It can also be
used in small fixed domes, providing all the features at a
tiny fraction of the cost of fixed dome projectors. The
Digitarium Alpha opens up a whole new world of topics that
can be covered outside of a large institution.
"The Digitalis projector is a true innovation for portable
planetaria," says Elizabeth Wiles, Community Education
Supervisor at Pacific Science Center in Seattle. "It is
compact, one-piece and easily transported -- no more
multiple cylinders, no more tiny planet pieces or moon
magnets. The software it contains increases a hundredfold
(maybe more) the capacity of topics we can do in the
