Cosmonova's projection dome is 23 meters in diameter, and is made of perforated aluminum, with a total surface area of 760 m². The panels are perforated in order to let sound pass through the dome, and also are an essential part of the ventilation system for the theater. The surface of the dome is finished with a special, electrostatically applied paint. The reflectivity of the screen is 35%.
The theater has 262 seats including three places for wheelchairs. The backs of the seats are tilted at different angles depending on which row in the theater they located. The tilt varies in order to have the best visual experience regardless of where you sit.
Audio is provided via a six channel sound system, with a separate sub-bass system, than can cover a frequency range from 20 to 20,000 Hz. Total amplification for the system is 15,200 Watts, delivering up to 110 dB sound pressure levels. The main sound source for the six channel system is a DDP-2 digital hard disk-based system. A 35 mm mag track and a DA-88 player are used for back-up.
Digital Automation System
The brains of the entire theater is SPICE (Special Projector Interface Control Electronics). SPICE uses SMPTE time code to control all of the different systems.
IMAX® Dome (Formerly known as Omnimax®) utilizes the world's largest film format; 70mm, 15 perf. It is ten times larger than the 35mm film used in most movie theaters. The large film format adds a heightened dimension of brightness, realism and sharpness not found in smaller film formats. Employing a fisheye lens, the projector can cover an angle of 180° by 125°, allowing the audience to become a part of the action projected onto the dome overhead.
When conventional movie film travels vertically through their projectors, Imax is such a large format that the film travels horizontally through the projector with the help of a special vacuum system that presses the film against the projection lenses back element in a precise motion. The projector's lightsource is a 15 kW xenon arc lamp that is cooled via chilled, filtered water that circulates through the projector.

Digital 3D Projection
Cosmonova's digital 3D system, which projects a 3D window over 17 meters wide, is made up of two Christie CP2000 ZX digital cinema projectors. They can produce about 35 billion colors and have a contrast ratio greater than 2,000:1. Inside each projector is a 3,000 watt Xenon lamp with a light output of 35,000 lumens. The supporting hardware can show high resolution films that are up to 3.5 terabytes in size, which is about a thousand times greater than that of a conventional DVD. The software supports uncompressed high resolution films in most formats. The system is capable of showing both 2D- and 3D-films.
In order to see our 3D films in stereo, glasses with active liquid crystal lenses are used. The glasses change between either let light comletely pass through them, or be completely blocked. The glasses switch back and forth between left and right eyes so that a person can only see with one eye at a time. The film's pictures alternate so that the left eye sees one picture then the right eye sees the next picture. Combining the views seen with both eyes leaves us with the impression that the film is in 3D. Since the pictures switch so rapidly -- every 1/50th of a second -- the images are flicker-free. The glasses are washed after each use in specially manufactured dishwashers.

Digital Fulldome Video Projection
With its new digital system Cosmonova is able to present both in-house produced and licensed planetarium shows as well as other fulldome content.
The system consists of six high resolution Projectiondesign™ F30 sxga+ DLP™ projectors. Each projector is hand-picked and all are colour matched with one other. Through a so called optical edge-blending process a single image is created on the dome with over 6 millions pixels produced by the projections from the six individual projectors. The edge--blending process is made possible thanks to laser correction adjustments via the Mercator™ and Navigator™ software programs.
The fulldome system´s projectors can provide approx 1 billions colours and have a contrast ratio greater than 7500:1. Two 300 Watt halogen lamps in each projector provide a brightness of 6500 lumens per projector, which are specially adapted for planetarium shows. The system has a total show storage capacity of 12 terabytes.
The advanced visualisation platform, Uniview™ is included in the system, which is used for showing astronomical data in real-time and in colour.
