Binoculars are also known as field glass or binocular telescopes. They are in lay man’s terms two telescopes held together and aligned in the same direction and levelled to point accurately in a certain direction. Although not as powerful as telescopes, they give a three dimensional image to view objects in a more magnified view. Since they are two tubes, they have to be held with both hands firmly and placed on one eye each to provide a few from both eyes.
Handheld binoculars are the most popular sort and are typically for tourist to use or for those interested in the works of the space.
