Did You Know?

  • All our customers receive free technical support, free films and exclusive operational tips 'n tricks
    • eg. learn to screen a fulldome film while at the same time working / answering emails on your laptop
  • Inflatable Go-Domes raised with one ring are less tall than non-raised equivalents and provide more useable space
  • ASE inflatable domes can be ordered with two adjustable heights
  • Geo-Go-Domes are available with horizontal or tilted domes - or both
  • Inflatable Go-Domes can be ordered with a sturdy wheelchair entrance
  • Spherical mirror projection is being used successfully in fixed domes as large as 15m and up to 20m in diameter
  • You can view an image gallery of spherical mirror installations from around the world here
  • Spherical mirror projectors can be upgraded easily, unlike fisheye lens projectors that require an expensive, projector-specific lens
  • Not all projectors are suitable for spherical mirror projection and this is how to test them
  • Unlike the original delicate mirrors, modern spherical mirrors are durable and can withstand touching and cleaning
  • Truncated fisheye projection (an attempt to increase the relatively poor resolution of fisheye systems) is very similar to spherical mirror projection
  • Spherical mirror projection provides between 28% better resolution (16:10 projectors) and 58% better resolution (16:9 projectors) than fisheye projection:
  • We also sell fisheye projectors. Yet customers hardly ever buy them because they are TRIPLE the cost of spherical mirror projection, with significantly lower resolution
  • Why then do people sometimes buy fisheye projectors?
    • they’re not aware of the new spherical mirror projection option
    • fisheye projection produces a full, uninterrupted horizon (whereas a spherical mirror creates small shadows on the dome behind it)
  • Yet consider this:
    • although some audience members may prefer a full, uninterrupted horizon; most won’t mind (or even notice) if you use the software to spin the sky around to show North, for example
    • it may be quaint to have the audience sit in a circle looking up at the sky (as if they’re outside), yet after 10-15min most people get bored of seeing stars (and very likely the sound of your voice!)
    • so next you’ll project astronomical images and video clips. Yet with fisheye projection such content needs to be radially symmetrical and positioned at dome zenith if the concentrically-seated audience is to enjoy it equally; limiting your choice of content
    • you’ll soon run out of radially symmetrical visuals (plus by now the audience is truly weary of your voice), so you decide to screen a fulldome film
    • yet 99.9% of fulldome films are unidirectional, which means at least half your audience will be watching the film upside down
      • you therefore ask everyone to move to the rear of the dome
      • this of course means that as with a spherical mirror system, you can never completely fill your dome
    • With so many restrictions and limitations, is it worth paying up to $20,000 extra for a fisheye projection system, just so you can offer a 'full, uninterrupted horizon'? Your expensive fisheye system will risk falling into disuse and collecting dust in a storeroom somewhere
      • we are occasionally approached by fisheye system owners enquiring what they can do to make their system as versatile as a spherical mirror system

Spherical Mirror Advantages

  • projector can be replaced or upgraded very easily

  • equipment is located at the back of the dome, freeing the centre with 20% more seating space

  • mirror less expensive to replace than fisheye lens
  • approx. 30-60% higher resolution (see above)
  • can also be used to project on a wall or ceiling

Spherical Mirror Disadvantages

  • creates a small shadow at the back of the dome

  • slight image distortion at the back of the dome

  • beginners require brief set-up time to align mirror

Fisheye Projector Advantages

  • 100% dome coverage

  • slightly easier for beginners to set up

Fisheye Projector Disadvantages

  • lenses usually custom-made, making projector upgrade impossible without a new expensive lens

  • equipment is located at dome centre, taking up the best audience viewing area

  • audience can tamper with projector and cables
  • approx. 30-60% lower resolution (see above)
  • significantly more expensive

  • often substantially heavier
  • In the English language the correct plural of planetarium is planetariums, not planetaria.

  • Low rate financial loans with no early repayment fees can be obtained from Zopa, the world's first and Europe's largest peer-to-peer lending service (helped us purchase our first mobile dome system 10 years ago).
