Binoculars are two mirror-symmetrical and identical telescopes mounted side-by-side and aligned to point accurately in the same direction, permitting two-eye viewing. Essentially, all binoculars and scopes are derived from classical telescopes, which consist, in their most basic fashion, of two lenses.
There are certain binoculars which are equipped with night-vision technology. Still, recent trends have brought down the price to more affordable levels. If you are a backpacker or will be doing your birding on a bicycle, then you may wish to consider mid size or even compact binoculars.
Size is dictated by the objective lens. Microfibre lens cloths are made of tiny polyester or polyamide fibers that are a thousand times thinner than human hair.
But still, a good pair of night-vision binoculars will cost at least a thousand dollars. Generally, a binocular lens cloth has a useable side and sometimes each side has different functions. But you d better make sure that they have the proper range, power and clarity.
Binoculars are easy to operate and allow viewers to concentrate fully on looking up into the sky. I tell most of my friends that they can get their Binoculars online now, however, one way I have found that helps is to contact the seller if you need more information.
