Any stain or mark on the surface of a binocular lens tends to scatter light, thereby producing low-contrast viewing. If you love bird watching, then a pair of binoculars with a wide field of view and a fully multicoated optics may just fit your needs.
The result is appreciable for many people considering the easier mobility and simpler operation of the binocular equipment. Exactly how you can see the Sun rise in the east, and set in the west; and how you can see the moon whizzing from one part of the sky to the other, when you take a look at the moon in a telescope it moves fast. The first number is the amount of magnification or zoom the pair has.
Optics in night vision binoculars amplifies the existing light. You will need a magnification factor of at least 7, maybe up to 10 if you have a steady hand.
It is also useful in ranging an object that is not perfectly horizontal or vertical, enabling you to determine the range without tilting the entire binoculars. Many astronomers are professionals, but amateur observers have embraced the romance of stargazing also. In most cases, pocket binoculars are of prism roof design and the front lenses and the eyes come in a straight line; such binoculars are usually compact.
There is much more to astronomy then buying a telescope. These tips hopefully will lend themselves to your benefit.
