Some disadvantages of using a sextant include the need for manual operation and calibration, the potential for human error in readings, and limitations in poor visibility conditions like fog or heavy cloud cover. Additionally, sextants require knowledge and skill in celestial navigation techniques, which can be complex and time-consuming to learn.
The horizon shades on a sextant are used to block out excess light from the sun or other bright sources on the horizon, making it easier to take accurate measurements of celestial objects such as stars or planets. They help to reduce glare and improve visibility when using the sextant for navigation or celestial observations.
Lewis and Clark used a sextant to determine their latitude by measuring the angle between the horizon and the sun or a star. This helped them navigate and map their route across uncharted territory during their expedition to the western United States.
The least count of a sextant is the smallest angle that can be measured with the instrument. It is typically determined by the design of the sextant and the precision of its scales. The least count is important for accurately measuring angles in celestial navigation and other applications where precise angular measurements are required.
The sextant was developed independently by multiple inventors in the late 18th century, including John Hadley and Thomas Godfrey. It is unclear who specifically should be credited with its invention, as the device was refined over time by various individuals.
Sextants revolutionized navigation by allowing sailors to accurately determine their position at sea using the sun and stars. This technology made it possible for ships to navigate more safely and precisely over vast distances, leading to the exploration and discovery of new lands. The sextant played a crucial role in expanding trade, colonization, and globalization in the 18th and 19th centuries.

A sextant is a navigational instrument that sights upon the stars to determine a ship's position. This instrument was crucial to naval navigation until global positioning became a reality in the late 20th century. "Henry the Navigator prized his sextant while on his journeys to the New World." "The ship's position is determined by the use of the ship's navigator using a sextant."
That is the principle of a sextant.
