ePlanetarium : Home of Discovery Dome
Welcome to ePlanetarium

We offer fully portable digital theaters with true HD (using all the width of 1920 and most of the height), with fulldome movies and zoom-in digital starfields. With support from NASA REASoN and a strong partnership with museums and universities, we bring the excitement of museum-quality shows, presenting a wide range of educational topics, in a state-of-the-art mobile digital theater system, to you. Our domes are fully flame retardant and handicapped-accessible, and users can come and go during a show. We offer new portable inflatable domes, new high-resolution projectors, and educational and entertainment shows, in additional to bringing "on the road" programs to schools and special events. Daily rentals available from our extensive partner network.

ePlanetarium®, along with Space Update®, is a division of MTPE, Inc., a woman-owned small business. "Brings the Professor to You"™.


Why Choose ePlanetarium?


Discover the Difference!

This isn't your old crawl-in star dome!

  • Fulldome Video with Sound: museum-quality fulldome shows are available on all science topics; project a dynamic night sky with stars, planets, constellations, and more.
  • Shows aligned with Science Objectives: over 80,000 students experienced a Discovery Dome in Houston alone in 2011 .. and over 90% of the teachers chose an educational movie instead of a star show... because it met their educational objectives!
  • Upgradeable Components: high-end off-the-shelf components can be upgraded as new projector or computer technology is released - never be stuck with old technology again! And get LOCAL service on your projector and laptop!
  • High Definition Resolution: true 1920x1080 gives sharp, vivid, images which fill virtually the entire dome!
  • Double the Pixels: almost twice as many pixels projected as Digital Starlab or the Digitarium Gamma from Digitalis! (They use only a 1080 circle - we use all 1920 across. We even have 30% more pixels than Digitarium epsilon.)
  • Walk-in Dome: stand up entry, no crawling required; continuous entry and exit without disrupting a show; handicapped accessilble! Special flap to allow projection even on the doorway. Widest range of sizes, types, and colors of any dome manufacturer - now with the new semipermanent Zodiac dome for sale or rent! Beware of imitations - we use only Go-Domes™!
  • 3D Available: Our new projectors change in a flash from fulldome to 3D - NO OTHER SYSTEM is that flexible! And now with "Mediawaarp 3D" available in our special 3D upgrade.
  • Custom Projection Surface: minimizes wrinkles, crosstalk, and sound echoes. Self-closing vents (now copied by Digitalis) allow ventilation without bouncing; resists deflation when large groups exit.
  • Highly Mobile: fast set up (less than 20 minutes), easy to operate, lightweight, easy for one person to carry in a compact car or check as airline luggage.
  • Ease of Use: MediaSHOW is designed for ease of use in having full control of images, movies, sequences, and clips. Training takes just a few minutes and is included in the price. And it is easy to create your own custom show from clips, stills, and sound!
  • Star-field Software: Stellarium, included free, is a collaborative software application that uses the talents of the entire community to provide the best software!
  • Compare to Digitalis or Starlab: See more reasons to choose Discovery Dome over Digitalis or Starlab by seeing our comparison.
