The Universal Sight Tube is a simple optical accessory for sextants used in astronomical navigation.<\/strong> The sight tube is mounted on the sextant instead of the telescope and provides a significantly wider field of view during observation.<\/p>\n

When navigating with a sextant, a telescope with magnification can make it more difficult to find celestial bodies quickly. A sight tube<\/strong> – also known as a clear tube<\/em> or peep sight<\/em> – provides a clearer field of view and makes it easier to locate the sun, moon or navigation stars before the precise observation is carried out. <\/p>\n

Sighting tubes were previously supplied as standard equipment on many sextants and are still used by many navigators as an alternative to a telescope for some observations. The wide field of view makes it easier to keep the celestial body in the field of view, which can be particularly useful when observing from a moving boat. <\/p>\n

The Universal Sight Tube fits most modern metal sextants with a standard telescopic mount<\/strong>, including models from Celestaire and Cassens & Plath<\/strong>, as well as several other sextants with similar mounts.<\/p>\n
