It is a plural-only noun (plurale tantum). We say 'The binoculars are...' not 'The binoculars is...'. To refer to one item, we say 'a pair of binoculars'.
Binoculars have two parallel telescopes, one for each eye, providing a stereoscopic (3D) view and often being hand-held for general-purpose viewing. A telescope typically has a single, larger objective lens or mirror for higher magnification, used more for astronomy or specialised long-range viewing, often on a tripod.
Not for the device itself. The singular 'binocular' is used as a technical adjective (e.g., 'binocular vision') or sometimes as a modifier ('binocular microscope'), but the device is always called 'binoculars' or 'a pair of binoculars'.
The first number (10x) is the magnification (objects appear 10 times closer). The second number (50) is the diameter of the objective lens in millimetres, which affects light-gathering ability and field of view. Larger second numbers generally mean brighter images but heavier binoculars.
