FREIBERGER FG-SF Starfinder-Globe english
The star finder globe shows the constellations and fixed stars as mirror images on a sphere. In this way, the starry sky is displayed true to life and without the distortion that is unavoidable in a two-dimensional display.
The sphere can be rotated according to the local hour angle and the world axis can be tilted according to the geographical latitude.
The star globe can be used for
- locating stars and constellations
- naming a measured star or determining the pre-setting values of the sextant for a measurement
- displaying the apparent star movement.
The celestial coordinates, local hour angle and declination (from the nautical yearbook) of a star can be set on the star finder globe. The azimuth, i.e. direction, and altitude to the horizon location can be read from the star location found in this way. This allows, for example, Venus, which is not visible to the naked eye in the daytime sky, to be found through the telescope of the sextant.
Conversely, azimuth and altitude can be used to determine the name of the unknown star at the celestial coordinates found.
The star finder globe is labeled in English, as is customary in the shipping industry. Alternatively, it is also available with German lettering. Please feel free to ask us about this.
As the starry sky changes, it makes sense to replace the actual sphere of the star finder globe every few years. This is the only way to ensure that the current star constellation is displayed. You can find the replacement globe under "Accessories & spare parts".
Technical features
- Total height: 210 mm
- Sphere diameter: 170 mm
- The star globe is supplied in a wooden box.
