Single scopes or spotting scopes, for example, are often used for hunting and bird watching. The key piece of equipment for bird watchers is binoculars.
They are suitable for a number of activities and adventures including bird watching, hiking, fishing, sporting events, stargazing, concerts, and nature observation. Binoculars have two specifications marked on the body of the binocular in the form of 7x 50, where the first number represents the magnification, in this case 7 times, and the second the aperture ,50mm in this case. Most pocket binoculars have multi-coated lenses and high-refraction prisms.
If your binoculars are going to be used during low light like hunting and astronomy, you had better have large objective lenses. Generally, if the objective lens is 50 mm then it is considered to be a large binocular; if it is 42 mm, it is full size; if it is 32 mm, it is a mid size.
The range of you binocular depends on three things, its gain, resolution and magnification. Everyone asks how to understand the magnification on binoculars. The objects may look bigger, but the images could be quite unclear.
You will also need to buy an atlas of the sky suited for astronomy, and a guide. As with almost everything else in life, with binoculars you get what you pay for.
