Abstract

Binoculars are considered binoscopes. We usually just think that binoculars are just binoculars. In reality, they are really in most cases a smaller version of a binoscope. Basically they are two small refractor telescopes that are optically aligned on the same object for viewing. Of course there are larger versions of the binocular. Some have objective lenses that are 150 mm in diameter and often 25 power or more. Being so large of a binocular, they have to be supported on a large tripod or pier. The view through a pair of 150-mm Fujinon binoculars is stunning to say the least. However, the expense that one has to pay for a pair of these fantastic large Japanese binoculars is often out of reach for the average individual.
