Although there are many other specifications and qualities which determine the usefulness of binoculars, we will discuss in this article the primary characteristics for determining the best fit for your application.

You position your telescope to look at the Moon, you see craters, and find that soon as you go to call someone to take a look, they take a look and it is gone. If you go over 10x, you should consider getting a tripod.
Generally, if the objective lens is 50 mm then it is considered to be a large binocular; if it is 42 mm, it is full size; if it is 32 mm, it is a mid size. Attached caps will protect the lenses, but not require you to fumble in your pockets looking for lens caps if it starts to rain or snow. Apart from a large number of big companies, there are local manufacturers which produce night-vision binoculars at a much lower cost.
