Binoculars are actually two telescopes placed side by side so a viewer can see through them with both eyes. Monocular are simple telescopes which are only half of a pair of binoculars.
Most places specializing in Binoculars cover birding and hunting and astronomy which are too powerful for the marine environment. First, determine just how and under what circumstances you will be using your new binoculars. Using binoculars, the avid birdwatcher can be sure he really saw the rare Bonaparte s Nightjar or Pink-Headed Fruit Dove, not just another sparrow or bluebird.
A simple coating was devised to prevent this, by allowing more light to pass through the lens, and less to be reflected back. The coating reduces glare and protects your eyes from UV rays, and increases the definition and clarity of an object. Compacts have objective lenses 25 mm or less.
Field-of-view is determined by magnification and the focal lengths of the objective and eyepiece lenses. Obviously, you can spend whatever you wish, but keep in mind you don t have to go overboard. They enable the user to spot far more stars, comets, galaxies, and nebulae far better than with the naked eye.
Night vision binoculars are a must for anyone in a profession that requires secret night work. Purchasing a pair of binoculars that have been designed with coated lenses will help extend the life of your binoculars.
