Beschrijving | : | Vliegtuig kompas / astro compass Mk II. Zwart kompas, licht metaal. Op drie stelpootjes. Op de onderste schijf staat: "A.M. Astro Compass Mk II 6.A / 11740 3x". Bovenop het vizier staat declination. The manual Astro-Compass is a device that is pointed to a known star (that includes the Sun) and then will indicate true North. Used by pilots and navigators to determine accurate true heading by the sun or stars in arctic regions. It is well suited for aligning a boat's compass while away from shore-based magnetic interference. It is also useful to celestial navigators and amateur astronomers for identifying stars. It also functions as a pelorus with extremely fast and simple operation. The astrocompass functions by means of measured movement in three independent axes. The uppermost member contains a peep sight for stellar use and a shadow bar for use with the sun. The main platform is adjustable by reference to two integral spirit levels. |
