    Polaris - especially for fixed star  and planet observations

    The Clear - View mirror combines the advantages of the Full - View mirror and the traditional horizon mirror. Large field of view and clear horizon sight.
    The astigmatizing lens simplifies the observation of the dot-shaped fixed star by elongating the light dot to a horizontal light line. Of course, POLARIS is suitable for sun observations,too!

    1- Clear - View Mirror
    Have you experienced the following problem? You had to shoot a dark star in the dawn. To enable you to cope better with this situation we developed the Clear View mirror. Only half silvered in the middle, it allows free sight to the horizon. The side areas are free of silvering. This makes possible a clear view to the horizon without additionally dimming the brightness in the dawn. The mirror area is of a reflection-transmission propotion 70:30 depending on the wave length of the light. This gives optimum adaption to brightness situation on sea at day and night. Resistance of mirror coating against humidity, saltwater and scratch are according to MIL standards.

    2- Astigmatizer
    Stars spread to light stripes. The sun extends to a light beam. "Swinging the arc" is not longer necessary.

    3- Combined Index Error and Dip Ajustment
    For index mirror correction it is no longer necessary to change the position of the mirrors itself. From now you simply turn an extra scale at the drum. The dip, a necessary correction of sextants, can also be corrected at the drum.

    4- Illumination
    The indirect, anti-dazzle illumination of limb and of minutes/decimal minutes at the drum will show the right star altitude immediately.

    5- Telescope 4x40 or 6x30 alternatively
    40 mm objective size will collect enough light to make observation possible even in dawn. 4 x magnification is suitable especially for astro observations but also for coastal horizontal angle observations,too.
    Alternatively a 6x30 telescope may be supplied. Recommended in case of larger yachts and more experienced navigators or especially for coastal navigation.

    6- Vernier
    Allows reading of angles with an accuracy of 0.1´.

    7- Vernier
    Dimensioned and adjusted to the size of the Clear-View mirror the Large-Field shades do not narrow the free sight through the mirrors.

    8- Index Mirror
    Metallic or reactive materials, that will be corroded by saltt water, are avoided. This grants long life of mirror coating. The mirror coating is scratch proof acc. to MIL specification.

    Name engravure
    You will receive POLARIS individually engraved with your name. Please state text with order, max. 30 letters.

    Memory Foil
    Writable foil at the handle to note star atitudes.
