Description

DESCRIPTION Almost From The Invention Of The Telescope In The 17Th Century The Advantages Of Mounting Two Of Them Side By Side For Binocular Vision Seems To Have Been Explored. Most Early Binoculars Used Galilean Optics; That Is, They Used A Convex Objective And A Concave Eyepiece Lens. The Galilean Design Has The Advantage Of Presenting An Erect Image But Has A Narrow Field Of View And Is Not Capable Of Very High Magnification.
