Long distance viewing binoculars are ideal for astronomy and for long distance terrestrial viewing. They can take the place of a telescope, and have the advantage of being much more portable.
Long distance viewing binoculars offer spectacular views of large celestial objects like planets, moons, and open star clusters.
Because both eyes are used for viewing, long distance binoculars offer complete stereoscopic and multidimensional images that cannot be achieved with a telescope.
Long distance binoculars also offer a much wider field of view than a telescope, allowing you to view much more of a particular object at once.
Long distance viewing binoculars have large objective lenses, with some measuring 100mm or more in diameter. A larger objective lens allows for optimum light transmission and the brightest possible view when studying the night sky.
The magnification power on long distance viewing binoculars generally ranges from 11x -30x. The higher the magnification, the more difficult it is to hold binoculars steady.
A pair of binoculars' long distance magnification is somewhat on scale with the size of its objective lenses. 70-80mm binoculars have a magnification of 15 - 20x, and 100 - 120mm binoculars of 25 -40x.
Long distance binoculars can be used in conjunction with a telescope. They can help to locate a celestial object, and the telescope can then be easily trained on it.
Long distance viewing binoculars are large in size and somewhat heavy. For better stability, almost all models come tripod-ready, and some models are sold with tripods as a set.
A tripod is optional for smaller long distance binoculars, but any binoculars with an objective lens diameter of more than 80mm will be very heavy and will definitely require the use of a tripod.
