How did sailors determine their position before there was GPS? This sextant replica from Hemisferium shows how that worked. With a sextant, you measure the angle between the horizon and a celestial body, such as the sun, the moon, or a star. Through mirrors, you project the image of the celestial body onto the horizon and read off the angle on the scale. With that height, a precise time and tables, sailors determined their position at sea.
The replica is made according to historical examples and is primarily intended as a decorative and educational object, for example for those who sail or are interested in maritime history. A predecessor on board was the historical marine astrolabe.
Never look at the sun, because suitable sun filters are needed for that. How to safely view the sun, you can read in safely watching a solar eclipse. The sextant is nicely positioned on a desk next to it. a globe of Zoffoli.
