Binoculars, an excellent way to get close up views that the human eye could never normally see, are made in a variety of strengths and styles. If it's long-distance sky-gazing or nature observation that you seek, the 25 x 100 binocular may be the ideal choice for you. The 25 refers to the magnification: Any 25 x 100 binocular will magnify objects to 25 times their normal size. The 100 refers to the lens size. A 100mm lens is among the largest of binocular lenses made, and is a good choice when you want to see a very large area, such as the night sky. The larger lenses have the additional benefit of being able to draw in more light than smaller lenses can.
