What is the purpose of the horizon shades on a sextant?
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.
Who built the sextant?
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.
How do you use a false horizon with a sextant?
To use a false horizon with a sextant, you would need to create an artificial horizon with a still reflecting surface, such as oil in a pan or a small pool of water. You would then line up the celestial body you are measuring with its reflection on the artificial horizon, allowing you to take an accurate sextant reading. This method is useful when the true horizon is obscured or not visible.
Where was the sextant invented?
