light weight binoculars - optics the easy way

Since the light has been refracted, or bent as it has been directed through the lenses, by the time the viewer sees the image it is back to front, and upside-down. Compact Nikon binoculars are the handiest and most versatile of all optical instruments I have used.

Kids use binoculars as toys and as learning devices. Pack them and you'll be looking off into the distance bringing everything so much closer. Monoculars are preferred when it is necessary to view stationary objects.

You will need a magnification factor of at least 7, maybe up to 10 if you have a steady hand. If you are using binoculars with a large, heavy objective lens it is helpful, if not necessary, to stabilize them by either resting them on something or mounting them on a tripod. The size of the binocular will probably affect the way they feel in your hands.

Most pocket binoculars also feature long eye relief. Furthermore, binoculars with a wide field of view allow a user to observe a wide area, making it easier to observe star clusters, comets, and galactic clouds. The coating cuts down on reflected and fragmented light inside your binoculars, and so increases, the brightness and clarity of the image.

When looking for a pair of binoculars to buy you may have to shop around. Adding optional features and devices will also increase the cost but may be worth considering.
