Apparently binoculars seems to be a poor optical instrument. Any average astronomical telescope can gain higher magnification and thanks to a big lens is able to gather more light. Fortunately, considering binoculars, magnification is not the most important thing.
A binoculars consist of three main optical parts: front lenses, prisms and eyepieces (oculars). Lenses conduce to gather as much light as possible. Eyepieces are essential to magnify the image and direct it into our eyes as a parallel light beam.
Most trappers asked for the typical and classic binoculars destined for night-hunting will point at model with 8x56 lens so equipment with 56 mm objective diameter and 8x magnification. Others will probably add 7x50 and 9x63 and that’s the end of suggestions.
