Some scopes which are not well proofed for water or fog, are not as rugged. Binoculars allow excellent moon views, and great viewing of star fields, comets and even deep sky objects.
The first thing to know about a compact binocular is that it is two small telescopes mechanically linked together. When you look at objects in the night sky, they are constantly revolving in its path, this makes objects move in the night sky. The magnification factor tells you how many times larger the object will be magnified, a number of between 4 and 7 is ample for most applications.
As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. That is to say, different users with different space between the eyes will be able to view the reticle horizontally. Water-shedding lens protectors have a special coating that allows water droplets to bounce off the surface, which helps reduce repeated cleaning of lens.
Also when you are looking for a pair of hunting binoculars you might want to look for a pair with a range finder feature. Coupled with the size of the objective is the light gathering ability of the lens and the field of view. The objects may look bigger, but the images could be quite unclear.
Purchasing a pair of binoculars that have been designed with coated lenses will help extend the life of your binoculars. So, get out there.
