Sextants
Sextants are navigational instruments used to measure the angle between two visible objects, typically the horizon and a celestial body such as the sun, moon, or stars. They are commonly used in maritime navigation to determine a ship's latitude and longitude while at sea. Sextants typically consist of a small telescope, a sighting device, and a graduated scale for measuring angles. They are essential tools for sailors and astronomers alike in determining their exact position on the Earth's surface.
