PROJECTOR

The Rigel projector Planetarium is the classic mobile planetarium of cylinders that it was very popular in the last 2 decades and selected by entrepreneurs, or learning centers with the purpose of offering educational services inside a dome representing the celestial sphere and other topics. 

The essential difference of Rigel planetarium with other simple and concise projectors of the market are several: 

True Astronomical planetarium for the celestial objects that it represents, besides also to be a projector of cylinders of several topics. 

The quality. 

The construction materials and components. (electronic platelets, microbulbo halogenous) 

The very low price of the market, with the most relationship benefit-cost.

CHARACTERISTICS

• It projects 2,750 stars down to magnitude 5.45.
• Hand - held constellation projector with 12 mythological figures.  (optional)
• The 5 naked eye planets.: Mercurio, Venus, Marte, Júpiter and Saturno.
• The Sun and the Moon with its phases.
• A comet which can be placed anywhere on the dome.
• It displays 13 naked eye objects: galaxies, nebulae, star clusters, and both Magellanic clouds.
• Six star colors.
• Graduated circle for terrestrial latitude.
• Blue enviromental light.
• It operates with 110/220 volts and a totally integrated electronic circuit.
• It has a 12 volt diurnal movement motor to simulation terrestrial rotation with variable speed.
• It has brightness controls for stars and blue environmental lights.
• The stars are projected through pin holes with halogen micro bulb. 

MOTOR 

The 12 volt diurnal motion motor (simulation of the terrestrial rotation which causes the motion of the stars across the sky) has variable speed: 1 revolution/minute until 1 revolution/20 minutes.

STAR BULB 

The star bulb is manufactured especially for this class of projectors. It has great yield and long useful life. Their very short filament, (0.75 mm) guarantees a punctual stellar imagen without distortion.

CONTROL PANEL 

1. 1  Direction of turn of the daily motion (for North or South hemisphere)
2. 2  Motor for daily motion of the stars.
3. 3  Stars brightness control.
4. 4  Led red on-off.
5. 5  on-off switch
6. 6  Environment lights brightness control.
7. 7  Plug/socket for hand held constellations projector.

HANDHELD CONSTELLATION PROJECTOR   (optional)

A manual projector of constellations can be bought separately with the projector Rigel. It is similar to a flashlight that uses special slides with 12 figures: Orion, Lepus, Taurus, Canis Major, Gemini, Scorpius, Cygnus, Crux, Leo, Hercules, Ursa Major, and Ursa Minor.

Eight additional constellations may be purchased: Sagittarius, Libra, Cassiopeia, Cancer, Draco, Corona Australis, Cepheus, and Canis Minor.

Didactically, this projector replaces to a cylinder of synoptic constellations, with the benefit of superimposing one by one, the imagaes of the constellations in their correct position in the celestial sphere.

The images are projected on the star field by the hand projector with its power source on the control panel

ANNEXED PROJECTIONS 

The RIGEL projector incorporates independent projections of the 5 naked eye planets: Mercury, Venus, Mars, Jupiter, and Saturn. They are seen as viewed through a telescope: Venus with its phases, Mars with its polar caps, Jupiter with its cloud belts and Great Red Spot, and Saturn with its rings.

The Sun and the Moon are projected phases.

A comet can be projected any place on the dome.

These views are done with small magnetic slides installed in the projector that are projected near the celestial equator.

MATERIALS OF CONSTRUCTION  

All the materials of planetary Rigel are made of aluminum, and the console of controls is made of iron, what gives a resistance and rigidity of the blows and bad treatments, derived of the continuous use.
