The key to a long and useful life for your binoculars is to follow the simple steps to protect against the unexpected. Before purchasing a telescope it is very important to know what you want and what.
This Leupold 10x50mm tactical binoculars is waterproof and fogproof. Coated optics will reduce light loss and glare, while giving you brighter image with less eyestrain. Many people prefer to carry binoculars around freely, rather than in a case.
Size is dictated by the objective lens. The area of land or sky that is presented to your eyes by using binoculars is referred to as the field of view. Since the advent of the original coating, the technique has been refined, and there are several grades of lens coating available.
The more important consideration should be the field of view. There is much more to astronomy then buying a telescope.
