The Transparent Celestial Globe is a model of the celestial sphere and may be compared with a world globe, which is a model of Earth. The globe is valuable in learning the locations, names, and shapes of the constellations much as the world globe is used in learning locations, names and shapes of countries and continents. When viewing the constellations and stars through the globe, or from inside looking out, the stars are seen in their true relationship, similar to viewing the heavens in a large planetarium where the stars are projected on a domed ceiling. The model also clearly and simply demonstrates the apparent relationship between Earth and the stars, planets, galaxies and other celestial objects in the universe. It is designed to show positions of the stars at any time and date as seen from any location on Earth. It is essentially a three-dimensional star finder and is not meant to show actual motions of Earth, moon, and planets. All observations are Earth-centred. Therefore, Earth is located at the centre of the globe. The handbook explains basic astronomy concepts and how to set the globe for time and place to show the actual positions of the stars. Once the globe has been set, it is possible to visualise what stars are visible and where they can be seen in the night sky. The 12-inch diameter transparent star globe surrounds an Earth globe mounted within the outer sphere. The terrestrial globe may be rotated independently with the knob at the South Pole. The stars in the heavens have been projected down to the 12-inch celestial globe, and this spherical star map shows and names the constellations, stars to the fifth magnitude, major nebulae, bright star clusters and the Milky Way. A moveable sun inside the star globe can be positioned by date time and place. In addition to the ecliptic scale, the right ascension and declination are indicated on the star globe. The right ascension scale is calibrated in hours and corresponds to longitude on the world globe, while the declination scales are calibrated in degrees and correspond to latitude. These scales are used in locating a star such as latitude and longitude are used in locating a place on Earth. For example, the location of Sirius would be given as right ascension 6h 43m and south declination of 16° 40'. At the North Pole are two dials. One dial is an hour dial and should remain fixed with midnight always towards the zenith and noon always to the north horizon. The other dial is a date dial and is on the celestial globe. These dials are used in setting the globe for a given date and hour as explained below. The durable, high impact globe has been printed on the inside so that a crayon can be used to mark the exact position of the planets, moon or other objects. The crayon marks can be removed with a soft cloth. The Basic Globe is a simplified version of the Universal Celestial Globe .The globe itself is identical to the Universal except it is mounted in a cradle base marked to indicate direction. The horizon is not depicted. Therefore, it is necessary to visualise the horizon as a horizontal plane extending in all directions from the globe centre. Also, the hour dial at the North Pole must always be set with midnight pointing up (or towards the zenith) when setting hour and date.
