Monocular are simple telescopes which are only half of a pair of binoculars. There are many options from very sophisticated binoculars for surveillance or night navigation to simple binoculars for kids to have fun with.
There are many ways you can use night binoculars. Consequently, spotting scopes are not only for the elite, but are becoming both essential and accessible equipment for the avid birder. Using binoculars, the avid birdwatcher can be sure he really saw the rare Bonaparte s Nightjar or Pink-Headed Fruit Dove, not just another sparrow or bluebird.
Size is dictated by the objective lens. Some of the greatest things you can see with a telescope are the moon and its craters. Modern lightweight binoculars have also evolved in terms of the use of roof prisms, rather than the traditional Porro prisms.
The first number gives the power of the magnification and the second number tells the diameter of the objective lens in millimeters which measures its light gathering strength. The larger the second number after the "x", the more light that enters the binocular and the image will become brighter. The more important consideration should be the field of view.
The greater the magnification, the narrower the field-of-view. Also be aware, that night binoculars cost much more than ordinary binoculars.
