Product Overview

A planetarium helps students grasp abstract astronomical concepts and can spark enjoyment and interest in science. Digitarium digital planetarium systems stand out in price and performance, putting a full-featured planetarium within reach.

Digitarium models are available in either a portable or a fixed configuration. Set up the portable version of this projector and a Digitalis inflatable dome in a gym for an instant planetarium. Portability and ease of set up and use allow you to share one system and its cost with other area groups.

The fixed versions are designed to be bolted down for permanent installation in a fixed dome. Digitarium systems offer an enormous range of features at a fraction of the cost of other fixed dome projectors.

Think of the possibilities of having your own easy to use, full-featured planetarium at your disposal. Avoid the headache and expense of organizing a fieldtrip to an off-site planetarium. You can use your projector as often as you need to cover your subject matter fully, and you can tailor your lessons to your students.

Digitarium systems offer advanced features to excite and engage your students. Zoom in on and label any object; demonstrate annual motion; display constellations from many cultures ; and much more. The systems vast capabilities make it relevant for audiences of all ages. Project your own content on any subject.

Digital technology makes these systems significantly more powerful than analog ("pinhole") portable planetariums you may be familiar with. Think of the power of a computer versus a slide projector.

Affordable and flexible, a Digitarium digital planetarium system will revolutionize your astronomy teaching.

Distinctive Features of Digitarium Systems

A number of features make our Digitarium system stand apart from other digital planetarium systems:

• Best usability. We believe our unique handheld, backlit remote control offers the best usability in the industry. It is easy to learn and use, and icons make it intuitive for any user around the world. With no separate control computer required, educators are liberated from complex software interfaces, arent tethered to the projector, dont need to block audience sight lines, and need only a fraction of the setup time. Devote your attention to your students rather than your system.
• Lowest training costs. Due to its excellent usability, no special operator training is required other than reading how to set up and put away the system. Our free lesson plans can get you started teaching right away.
• Fast setup/takedown time. With the portable version, from the moment you open the transit case until the sky is projected on the dome takes only a couple of minutes. Takedown requires about the same amount of time. Watch how easy it is to set up.
• Fully immersive experience. We believe projecting the full sky and horizon is absolutely critical for effective planetarium teaching. If parts of the sky are missing, not only is it harder for students to orient themselves, but it places limitations on what you can demonstrate easily. The full immersive experience for an audience will be ruined by standard application windows, desktops, projector reconfigurations, and other awkward and jarring transitions. Thats what makes our embedded system so magical.
• Reliable. The Digitarium systems do not use laptops which could overheat, and the operating software is stored on a highly reliable solid state flash disk. Our two year limited warranty is twice as long as that of most other sytems.
• Upgradable and modular The modular design and shared components between Digitarium systems means they can be upgraded or serviced down the road at lower cost. Most components can be serviced locally in developed countries. The computer control unit can even be serviced by the user (with our instruction) should there be a problem.
• Small footprint. When in use, Digitarium portable systems can take up less than a 20 inch/51 cm square area in the center of the dome. Thats roughly the equivalent of just one adult sitting cross-legged. The remote control fits in your hand.
• No software headaches. We manage your software for you, so you dont have to worry about it. We fix bugs and add features over time, and all you have to do is connect your system to an ethernet network and ask it to update itself. Software updates dont require hardware upgrades as one competitor cautions.
• Unique software expertise. We are one of the main developers of the open source planetarium software that we use, Nightshade. Unlike many competitors, this means we are intimately familiar with the planetarium software in our systems. We can easily fix bugs, add features, and make these changes available to our users.
• Most cost effective full-sky digital planetarium system. We designed from the start for higher volume, lower overhead production and distribution, and lower pricing than our competitors in order to put our tools within reach of most educational institutions. Even at affordable prices, we believe our systems match or outperforms many more expensive models on the most important criteria for practical astronomy education. We invite you to compare competing products in person and see this value for yourself. Paper comparisons just are not the same as seeing in person.
• The market leader. You dont have to take our word that we have the best portable planetarium for astronomy educators. Our Digitarium systems are the best selling portable digital planetarium systems in the world. With the first model introduced in late 2003, we now have users across five continents.

Digitarium Features and Benefits
