Binoculars or field glasses are two telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects.
- The first big difference between binoculars and telescopes is the number of lenses and eyepieces they use. Telescopes use one of each, while binoculars have two eyepieces and two lenses. While this sounds like a straightforward difference, it has a lot of ramifications for the image you’ll eventually see.
- In case of telescope, you continuously keep one of your eyes closed that is quite irritating if you are using it for a long time where as binoculars are comfortable.
- In case of the telescope, A normal shake of hand can get the subject out of sight whereas in case of binoculars that is not a problem.(Telescope generally has a greater optical zoom).
- binoculars can be stored in small places also.
- binoculars typically have between 6x and 12x magnification. That means an image will appear six to twelve times large than it would with your naked eye. While you can find binoculars with greater magnification, they typically require the use of a tripod, as the slight movements of your hands while holding them will lead to a very shaky image.Telescopes, on the other hand, start at about 20x magnification. High-quality models, which can run hundreds or thousands of dollars, may come with a spotting scope that provides 30x magnification, and the main telescope that can provide many times as much magnification.
