ORPHEUS special website


The Next Generation of opto-mechanical projectors has arrived
Its name is GOTO ORPHEUS

ORPHEUS is not only GOTO INC’s newest projector, but it is also the most versatile. By choosing different configurations of ORPHEUS, planetariums with tilted or horizontal domes with diameters from 8 to 21 meters can be served. Whether the need is for a state of the art HYBRID planetarium with totally unique features for a large, multi-purpose, public planetarium, or an easy-to-use basic astronomy education tool for a small school, or anything in between, ORPHEUS can supply what is needed.

With two major versions and a host of available optional features, the ORPHEUS can be custom-built to meet your specific needs. Designed to be hybridized and synchronized with select fulldome video systems, it also can function as an amazing stand-alone projector for special users, or as a show-saver should a fulldome computer or video projector fail.

Features

GOTO ORPHEUS Standard Features:

  • Extremely compact size – with a starball only 48cm in diameter
  • 9,500 tiny stars down to mag 6.55, against an ink-black sky
  • The detailed Milky Way, made of 8,000,000 micro stars, is independently dimmable
  • Brilliant, LED illumination of all objects, for a long lifetime of low power consumption
  • “Library quiet” operation – 41dB is much quieter than previous GOTO models
  • Digital horizon shutters for tilted or horizontal domes, or to raise the horizon above panoramas, or “all open” for a theater literally full of stars – even aimed downward
  • Embedded video projector shows gorgeous moon features, sliver-thin crescents, and lunar eclipses in full color
  • 56 nebulae and clusters beg for binocular viewing
  • Accurately positioned, very bright sun moon and planets are mounted on the ORPHEUS main body for the smallest projector footprint in your dome
  • Unmatched reliability and low maintenance costs due to GOTO’s 30-year design lifetime

Exciting Optional Features:

  • You can choose to have all 88 constellation outlines projected from the starball, 66 with independent control
  • Choose whether all stars or only the brightest stars twinkle, with user-controlled intensity
  • Choose only Betelgeuse or up to 10 stars to exhibit variable star dimming
  • Choose 20 or 299 stars showing correct color temperatures
  • Choose detailed ecliptic, equator, and precession circle coordinate lines
  • Choose environmental lighting including Cardinal Points, blue sky, twilight glow, and colored sunrise and sunset glows
  • Elevator lifts to lower or raise ORPHEUS projectors

A new, totally unique capability

ORPHEUS projectors designed for larger domes have a feature never seen before in an opto-mechanical projector. In this configuration, stars dimmer than magnitude 3.5 are grouped in half-magnitude sets which can be dimmed or switched on or off individually. So an operator can selectively turn off dimmer sets of stars to very realistically simulate an urban, light-polluted sky, or a smoke-filled sky, or to simply tune the sky to precisely match the sky just outside the planetarium door. ORPHEUS produces the most realistic skies ever seen in a dome.

Specification

  • Dome diameter range : 8 ~ 16m( Horizontal or Tilted Dome / Option : up to 21m )
  • Standard seating: approx. 100 ~200 seats
  • Fixed Stars : 9,500stars down to mag. 6.55
  • Micro-stars of the Milky Way: approx. 8,000,000 stars

The GOTO ORPEHUS HYBRID PlanetariumTM

While all ORPHEUS planetarium projectors can perform beautifully as stand-alone projectors, they are even better when synchronized with a colorful, dynamic fulldome video system in GOTO’s superb HYBRID configurations. When the stars, sun, moon, and planets of the ORPHEUS move, all fulldome video projections move with them. So the operator can elect to add even more complex computer-generated coordinate lines, pointers, and markers onto the sky, use constellation outlines from various cultures, leave star or planet trails, move the planets to show an orrery with orbital paths marked, and create hundreds of other demonstrations.
GOTO joins with only a few selected fulldome manufacturers in creating these HYBRID systems. And since each HYBRID includes a complete fulldome system, fulldome movies can be shown, simulated flights through deep space are possible, and a myriad of other fulldome effects are available to the operator.
GOTO knows that fulldome video systems are increasing resolutions to as much as 8K and even more in a few cases. But the tiny stars of the ORPHEUS have a resolution equivalent to 70K! Likewise, the ORPHEUS sky shows much more dynamic range in brightness of objects, and a much blacker sky between stars than any fulldome video system can. ORPHEUS is unarguably best at showing the pure night sky. Fulldome is best at showing animated color scenes. With the ORPHEUS HYBRID, you get the best of both technologies synchronized under one user-friendly control system.

GOTO HYBRID Control

In addition to standard automated control, ORPHEUS HYBRID systems are equipped with GOTO’s unique HYBRID manual control system. Consisting of 5 panels containing over 200 dedicated button switches, analog sliders, and knobs, this control system is without equal in the planetarium world. Each discrete physical control triggers a specific effect.
Like a master pianist playing a piano without conscious thought of particular notes, a GOTO HYBRID planetarium operator smoothly touches the controls to bring forth the desired sky scene without being forced to squint into bright computer monitors, read down long feature menus, or click on tiny on-screen control targets.
The result is that GOTO HYBRID operators can maintain an uninterrupted rapport with their audiences. Their speech has no awkward pauses when trying to interpret a complex computer screen. They easily control all functions of the planetarium without the need for a second operator to “wrestle the computers.” Live programs are a pleasure to present with a GOTO HYBRID.

The Smartest Choice – The Best Value

With its superior sky resolution, brightness, color, contrast, and ease of control, the ORPHEUS HYBRID planetarium is obviously the system of choice. But did you know that it also delivers the best value? Depending upon system configurations, a new GOTO ORPHEUS HYBRID using the 70K starry sky and synchronized 4K fulldome video may cost less than many 6K video-only fulldome systems. And it costs much less than 8K video-only systems!
While the ORPHEUS projector is designed for a lifetime of 30 years or more, video projectors in all fulldome systems have a life cycle of 5 to 7 years. So whenever video projectors approach failure, a 6K system must typically replace all 6 of its projectors at a high cost, and an 8K system must replace all 10 of its expensive video projectors - every cycle! Yet a 70K ORPHEUS in a synchronized HYBRID system using 4K video must replace only 2 video projectors each cycle. So… do the math. The ORPHEUS HYBRID not only costs less initially, but it will cost much, much less over the full lifetime of your planetarium.

Origins of ORPHEUS

ORPHEUS is a minstrel who appears in Greek mythology and known as the harp expert. It is said that people and forest animals, even trees and
rocks listened that beautiful sound. We named this name as our new planetarium projects the starry sky that remains in our heart as if the sound he plays.
