Celestron  Binoculars

Everyone should have a pair of binoculars whether you have a telescope or not. They are compact, easy to use on a moments notice, portable, handy to keep in your car. Binoculars are sized by the magnification or power and by the diameter of the front lens (objective lens). A 10x50 binocular has 10 power. This makes the image you view appear 10 times larger or 10 times closer. The 50 stands for 50 millimeters (about 2”) diameter objective lens. Large objective lenses gather more light making image brighter, clearer with more detail and are preferred for night use. Optical coatings improve image sharpness and contrast. Coatings vary from Coated, Fully Coated, Multicoated, to Fully Multicoated on the better models. Most models are adaptable to mounting on a tripod for a more steady view. Eye relief is how far back in millimeters you can look and still see the full field of view. Eyeglass wearers need long eye relief.
