Before even considering what type of binoculars to buy, it is necessary to understand just how these trusty devices work. Binoculars are essentially dual refractor telescopes for each eye; made up of a series of curved lens0 that refract and reflect the light from the object in view, and magnify it at the eyepiece. They come in a variety of magnifications (power levels) and apertures; as well as other technical specifications to enhance the sharpness, clarity, light resolution, etc of the distant object.
0The magnification of the binoculars is inversely proportional to the aperture (width of the objective lens); so if you have a high magnification, the object will become closer while […]

Of course, a toy store telescope will not be able to put into view the same objects as the Hubble Telescope can. Somewhere in the middle is a modest, but good-working telescope for the amateur astronomer.

To see how this viewing tool works, you must understand something about the eye, particularly about the retina. There will always be things you cannot see from far away. You must ask yourself why you cannot see them. There are two main reasons.

The other reason is that the object takes up so little space on your retina that it is impossible to get a clear picture of it.
