The telescope provides moderate magnification and a clear field of view, making it suitable for both training and practical <strong data-start=\"460\" data-end=\"487\">navigation with a sextant<\/strong> at sea. <\/p>\n<p data-start=\"499\" data-end=\"848\">When observing with a sextant, the telescope is used to see both the celestial body and the horizon clearly. The <strong data-start=\"616\" data-end=\"624\">3.5\u00d7<\/strong> 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.  <\/p>\n<p data-start=\"850\" data-end=\"1132\">The telescope has been specially developed for use in <strong data-start=\"893\" data-end=\"913\">astro-navigation<\/strong>, 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. <\/p>\n<p data-start=\"1134\" data-end=\"1396\">The Celestaire 3.5\u00d740 Telescope is a <strong data-start=\"1168\" data-end=\"1199\">universal sextant telescope<\/strong> that fits several modern metal sextants.
