Thanks to their upright image and wide fields of view, binoculars keep everything as it was meant to be, making it easier to find your way around when comparing the view you see to a star chart. The wide fields of binoculars also let us enjoy some sky objects that are simply too large to fit into a telescope's limited field of view. The Pleiades are one example. Beyond aesthetics, research shows that visual acuity is greatly improved by using two eyes instead of only one.
Binocular vision enhances our sensitivity to subtle differences in contrast, resolution, and color.
