5 inch Marine Sextant Large Brass Navigation Instruments Vintage Style Sextant Ship History Sextant

A sextant is an instrument used to measure the angle between any two visible objects. The sextant was the primary instrument used for navigation at sea for hundreds of years. Without the invention and use of this instrument no one would have been able to travel and find the "New World" and therefore none would be here in the Americas. The nautical sextant is designed for navigational and astronomical purposes and allows horizontal and vertical angles to be measured. It is used in marine navigation for measuring vertical angles to stars, occasionally, also for measuring angles between terrestrial targets. The instrument is also fitted with filters, or dark-coloured glasses, which can be swung into position when needed, and are generally used for solar observations. The structure of the sextant is based on the theorem that a ray reflected by two mirrors is deflected by twice the angle enclosed by the mirrors. The sextant is a free hand instrument and so it's accuracy may be limited. It must be noted that the sextant measures angles, and not directions or bearings, and is a more accurate instrument than the compass, but not as accurate as the theodolite. The sextant however, in general, is lighter, more portable, and quicker to use than the theodolite. It can also be used from a moving platform, such as a ship or a small boat, where it is impossible to use a theodolite.

About The Product
The nautical sextant is designed for navigational and astronomical purposes and allows horizontal and vertical angles to be measured. A sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon which is known as the altitude. Making this measurement is known as sighting the object, shooting the object, or taking a sight.
This instrument is an excellent tool for determining the angle between the horizon and a celestial body, making it invaluable for navigation and astronomy. It measures the angle between two objects with precision, utilizing high-quality glass optics that provide a clear and unobstructed view—no plastic lenses are used, ensuring durability and clarity.
When in use, you can easily observe the horizon through a strategically placed mirror, allowing for accurate alignment and measurement. While it is not calibrated, its robust design and reliable optical components make it a practical choice for enthusiasts and professionals alike, facilitating a deeper understanding of celestial positioning.
