Binoculars allow excellent moon views, and great viewing of star fields, comets and even deep sky objects. The lens nearest whatever is under scrutiny provides an image, which can then be enlarged by the lens nearest the viewers eye by moving it closer or further away from the objective lens.
Pocket binoculars are so handy and easy to carry. Digital binoculars are a cheap alternative, and can be picked up for considerably less money, and usually have a built-in camera. Compact binoculars have a very small objective lens, and this feature makes them user friendly.
In live theaters and concerts, audience members sitting in the back rows away from the stage use binoculars to get a better view of the stage. The size of the binocular will probably affect the way they feel in your hands. The waterproof models will be corrosion resistant and buoyant, not just repelling water from the lens.
Some binoculars come with special fire coating on the lenses. There is nothing like owning your own telescope, and being able to direct it through the sky to uncover a sea of beauty.
