Since the dawn of time, man has looked up at the heavens and wondered the beauty it may contain. Defense forces and intelligence agencies use binoculars to observe the enemy from a safe distance.
The power of the optics is expressed as two numbers, such as 7 x 35. Binoculars provide three dimensional images that have more depth. The binocular rating has two basic parameters, magnification and aperture.
Numbers are used to describe the telescopic strength of the binoculars. Such lens cloths take even fingerprints and stains of all sorts off your binocular lens. Most binocular lens protectors are replaceable.
Each coating is designed to provide the maximum transmission of light through the lens, and minimum reflection and diffraction, resulting in a brighter, clearer picture than with standard non-coated lens models. One of the most significant advances in optics is in water and fog proofing. Galactic clouds and star clusters look dim when viewed by the naked eye, but with binoculars they are much clearer.
The question how to buy a telescope is not a big one, more what you want out of the telescope. If you want powerful night vision optics for a cheaper price, consider night vision monocular.
