High resolution immersion with a minimum of fuss.

Our Æthos (AY-thos) systems are high resolution, multi-projector digital planetarium systems for fixed domes of all sizes.

Æthos systems embody our time-tested design philosophy with our well-known focus on ease of use, quality, support, and educational integrity. We have eliminated most of the complexity and headaches typical of multi-projector systems so that you can focus on your audiences rather than your equipment.

Specifications

Ease of Use
User Interfaces
Ergonomics Operator is untethered, and can use tactile wireless interfaces comfortably from anywhere in the dome. There is no laptop computer to hunch over or illuminate the dome with.
Multimedia Support Perspective, fisheye, and 360° spherical images and videos could not be easier to display anywhere on the dome and manipulate live.
Immersion Level Full. The audience is immersed in the simulation, and you can easily travel contiguously through time and space to demonstrate different concepts. Media are displayed within the simulation. No user interfaces need to distract the audience, and there are NO discontinuities. (Compare to other systems that break the immersion by requiring switching applications or software modes to show different locations or types of content.)
Software
Simulation Software Exclusive Nightshade NG universe simulator from Digitalis. Unlike desktop software, Nightshade NG was designed for planetarians by planetarians.
Included Content
Scripting Capability All system features can be scripted using StratoScript by Digitalis. StratoScript is a simple, yet powerful macro language specifically designed for planetariums and even non-programmers.
Software Updates All system software is maintained by Digitalis, and updates over the Internet with new features and bug fixes are free for the life of your system. You never have to pay to go from version to version, which is a huge savings over many competing systems. Software updates run at your command, so they will never get in the way of using your system like can happen with Windows computers.
Support
Training Onsite training is included. Online training via Zoom is available. Optional training academies are offered regularly for more advanced topics, like scripting. Priority support plans include a complimentary Academy registration.
Technical Support Free standard technical support for the life of your system. Priority Support extended support options are availble.
Warranty Three year limited warranty. Contact us about extended warranty options.
Community Free membership in our Digitarium user community website to connect with other users around the world and share ideas and content. Online user group meetings are held regularly throughout the year via Zoom.
Projection Qualities
Maximum Dome Diameter  
The largest dome that we recommend for this system due to brightness.
33m / 107 ft
Fulldome Projection  
Fulldome projection offers the most immersive experience and the easiest teaching methods (no parts of the sky are missing).
Yes. 180° x 360° field of view for full sky projection from horizon to horizon with no cutouts.
Projection Uniformity  
Non-uniform projection, such as from spherical mirror projection, can be very obvious and distract from your teaching.
Consistent focus, contrast, brightness, and pixel sizes across the dome.
Pixel Diameter  
The number of pixels from one side of the dome to the other, passing through the zenith.
4k or 8k
Projected Resolution  
The total number of unique pixels projected. The higher the number the more detail you can see, such as the phase of the unmagnified Moon from Earth.
up to ~40 megapixels (without double counting overlapping areas)
Pixels per Linear Degree of Sky  
This is another way of stating system resolution and how much detail can be shown. Consider that the angular size of the unmagnified Moon is only about half a degree, meaning it will be half this pixel count high on the dome.
up to 44
Lens Technology Cove (edge of dome) or center mount projection lenses.
Projection Technology  
DLP (Digital Light Processing) is a time-tested solid-state projection technology using micro-mirrors.
DLP or SXRD chips
Base Projector Brightness  
For comparison purposes, this is the base projector brightness without accounting for using a fisheye lens.
up to 40,000 lumens each
Projector Contrast Ratio  
The contrast ratio is the ratio between a white and black scene. The higher the ratio, the more realistic the projection can look.
up to 10,000,000:1
Light Source Laser
Illumination Lifetime Typically 20,000 hours at highest brightness
Hardware Details
Audio Up to 7.1 audio output. Dante digital audio optional.
Computer Computer with powerful (not weaker mobile version) Nvidia GPU is mounted to the system enclosure to reduce setup time. An ultra-reliable embedded operating system keeps everything running behind the scenes without user intervention.
Modularity Computer, projector, and lens are modular so that each can potentially be upgraded separately.
Mechanical
Projector Placement Cove (edge of dome) or center mount options.
Installation Professional installation is included.
Total Cost of Ownership (TCO): Future Year Costs  
Any purchase can require significant ongoing maintenance and support costs that must be considered when making a buying decision.
Support Costs We highly recommend one of our Priority Support plans.
Software License Costs $0/year for software updates for the life of your system (unless you opt for a subscription based license). Compare to limited period or version-limited licenses on other systems.
Consumables  
Consumables are items that are used up or must be replaced periodically.
Lens cleaning fluid/wipes and remote control batteries.
