THE ASTRA IIIB SEXTANT
The Astra IIIB has somewhat revolutionized celestial navigation. Never before has such a high quality, accurate, metal sextant been available at such a low price. Over 13,000 sextants of this model have been sold in the US alone in the past 15 years; far more than any other serious sextant. Its popularity has spread throughout the rest of the world as well.
The frame is made from lightweight aluminum alloy which resists corrosion. Aluminum alloy is not new to sextant construction. It is currently used in Freiberger sextants, and by C. Plath for a lightweight version of their famous Navistar Classic sextant. The sextant is electrically lighted by LED on the arc and drum.
