This article has been written to help you learn how to evaluate binoculars and then show you how to choose binoculars based on your budget and the purpose for which you plan to use them. Optics and personal preference seem to be the foremost, but here is a list of issues you should consider.
With a little practice you can pick out several of the planets and even the larger moons orbiting Jupiter. The binocular rating has two basic parameters, magnification and aperture. The first is the number of times magnification, and the second is the diameter of the objective lens.
A good rule of thumb is, unless you are a private investigator or international spy, avoid buying a pair of binoculars with a magnification/zoom greater then 10x's. The best result is achieved when multiple layers of coatings are applied, to the front and rear of the lens. The area of land or sky that is presented to your eyes by using binoculars is referred to as the field of view.
Always make sure that you buy from reputable sellers. In my opinion, one should be prepare to purchase a binocular worthy of your endeavors.
