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 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.
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.
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.

Yes Christopher Columbus did use a sextant along with a compass, ampoletta, and a cross staff.
The term "sextant" comes from the Latin word "sextans," meaning one-sixth. This refers to the instrument's ability to measure angles up to one-sixth of a circle (60 degrees). The sextant is commonly used in navigation to determine the altitude of celestial bodies.
