Kollmorgen 20 X 120 is known as one of the most massive “Navy Big Eyes” ship binoculars used by the U.S. Navy. U.S. Navy ships would mount a 20 X 120 Big Eye binocular on the deck just off the bridge. The 45-degree lens angle provided ease of use aboard ship where lookouts could spend hours scanning the horizon.
Long-range military observation relied on Big Eye binoculars since the late 19th century. They were preferred for their large magnification, which gave a significant advantage out at sea.
Uses
These 20 X 120 binoculars are great for astronomy as they perform beautifully in low-light conditions. However, they are quite large and can be quite heavy, so they must be mounted either permanently or on a heavy-duty stand.
If you enjoy the industrial look, you can keep them in their original glory painted with Navy grey paint, or have them polished down to a shiny brilliance and they will become a focal point in your home, office, or on the deck of your yacht. As a functional piece of art, you will enjoy star gazing in style.
