    Celestaire Astra III Professional Sextant - Split 0502P

    Just as the Astra IIIB has become world famous as the premier low cost metal sextant, the Astra III Professional Model, with its low cost, high accuracy and excellent handling qualities, is destined to be the standard for professional seamen.

    Its construction is similar to the Tamaya sextants in that it has a bronze arc fused to an aluminum frame. The bronze arc can be manufactured to a higher tolerance than aluminum, which gives the sextant higher accuracy. At the same time the aluminum frame keeps the over-all weight low enough that fatigue is not a problem as with a solid bronze or brass sextant. Nevertheless, the additional weight of the bronze arc adds about 8 oz. and gives the instrument an excellent balance and 'heft'.

    Features:


    • Ability to quickly and economically change the type of horizon mirror
    • Inexpensive replacement parts aids maintainability when students mishandle the sextant
    • LED lighting of the arc and drum (powered by 2 AA batteries - not included)

    Specifications:

    • Arc: -5° + 130° - radius 6" (153 mm)
    • Accuracy: ± 15 sec. throughout the arc
    • Micrometer Drum: 1' scale - vernier to 0.2'
    • Mirror Configuration: Split (Traditional)
    • Horizon Mirror: 2" (51 mm) diameter
    • Index Mirrors: 2.2" x 1.65" (56 mm x 42 mm)
    • Shades: 4 index - 3 horizon
    • Weight: 3 lbs, 2 oz (Sextant Only)
    • Case Dimensions: 6.5" x 13" x 11"

    In the Box:

    • Celestaire Astra III Sextant
    • Varnished wooden case
    • Instruction book included
    • Adjusting wrench included
    • Certificate of accuracy
