Description
The Celestaire 3.5×40 Telescope is a universal telescope designed for use with a sextant for astronomical navigation. The telescope provides moderate magnification and a clear field of view, making it suitable for both training and practical navigation with a sextant at sea.
When observing with a sextant, the telescope is used to see both the celestial body and the horizon clearly. The 3.5× magnification provides a stable image and a wide field of view, making it easier to keep both the edge of the sun and the horizon in the same field of view. This is especially useful during practical observations in waves or in changing weather conditions.
The telescope has been specially developed for use in astro-navigation, and the optics are adapted for observations of the sun, moon and stars in combination with the horizon. The moderate magnification makes the instrument easy to use and provides a stable image even when the sextant is held in the hand.
The Celestaire 3.5×40 Telescope is a universal sextant telescope that fits several modern metal sextants. It can be used with Celestaire Astra IIIB, Astra III Professional, as well as sextants from Cassens & Plath, C. Plath and Tamaya.
Often used as the standard optic on many sextants, this telescope is a practical accessory for navigators who want a robust and easy-to-use sextant telescope for sailing.
