The largest binocular telescope can magnify the scene by a factor of 35. Compared with ordinary medium-sized binocular telescopes, it has a magnification of 6~7 times, and the image is very clear, which is suitable for observing wild birds or other scenes. The 7×50 engraved on the barrel represents a 7x magnification, and the objective lens has a diameter of 50 mm.
Life application
Birdwatchers often use binoculars to make distant objects, such as birds, appear larger. A binocular telescope is actually just a pair of telescopes, with each eye looking at one side. There are multiple prisms (triangular glass) zigzag reflections of light, making binocular telescopes much shorter than monoculars; The prism also straightens the image up and down. With a binocular telescope you can judge the distance with both eyes at the same time, but not with a monocular.
Military binocular telescope
Military binocular telescopes are based on the Kepler telescopic optical system and added to the image rotation system (generally using prism to rotate images). The lens barrel may be equipped with a photosensitive element capable of detecting targets with infrared sources. Generally, the eye distance adjustment range is 54mm to 74mm, the viewing magnification of handheld type is 6x to 15x, and the rack-mounted type is 20x-40x. The optical performance of binocular telescopes is often expressed in two sets of numbers ×D.
Scientific advice
Astronomical landscape God of War moon, binoculars observation will be better.
