Using a binocular or a spotting scope is to look at virtually anything that you look at with your eyes and greatly enhance that view. Possible applications include:
- .Long Distance Observations
- Museum Visits (binoculars only)
- Nature Study
- Boating (binoculars only)
- Sporting Events
- Concerts (binoculars only)
- Target Shooting
- Theater/ Opera (binoculars only)
- Flying (binoculars only)
- Government – law enforcement/ military, air traffic control, search & rescue, security, and many other facets of local,state, and federal agencies

What is a Binocular?
Simply, a binocular is two low-powered astronomical telescopes with erect image mounted together. As compared to a best spotting scope, binoculars allow you a more comfortable viewing experience by using both eyes in a relaxed manner with a three-dimensional view.
Any binocular has two basic functions:
1.To gather more light than the unaided human eye does
2.To enlarge the image of what you are looking at
However, a binocular is much more than a basic definition. A binocular can:
- Open up new vistas of learning
- Add pleasure to your life
- Create excitement with new discoveries
- Help while hunting when searching terrain for game
- Add new dimensions to whatever you enjoy looking at
- Expand hobbies to gain more fulfillment
- Aid in your appreciation of the world
Allow families or friends to share the enjoyment of observing
Do not be embarrassed to ask questions about products that you may have or are interested in and remember that no question is stupid as it is important to you. With binoculars, two questions commonly asked quite often:
- How far can I see?
- What is the most power (magnification is a frequently used synonym) I can get?
Both questions are quite valid and they are the same ones that I asked when first introduced to optical products and being quite naive.
Our naked eye allows us to see the Moon that is an average 238,900 miles (384,500 kilometers) away. We can see Saturn which is 800 million miles (1.29 billion kilometers) away, we can look at deep sky objects like the Andromeda Galaxy which is the nearest galaxy to ours and it is 2.5 million light years away (a light year is 6 trillion miles or 10 trillion kilometers). However, to see objects on our own Earth, there are limits to what details we can see by the atmosphere with its varying environmental conditions. Thus, the limits to what optical instruments can actually see mean you need to consider carefully the optical quality and specifications of the products. Power is arrived by the optical design and higher powers are not always the best choice. Binoculars come in a multitude of sizes and powers but the majority range in power from 7x to 10x with objective lens sizes of 25mm to 50mm.
Giant binoculars are those with objective lens sizes of 70mm and larger and these typically are used mounted on rigid tripods. These large binoculars are for astronomy and for terrestrial applications. The choice of prism type has a large effect on the physical size of binoculars. Roof prisms are in-line designs so they are longer and narrower while Porro prisms types are shorter and wider. This is confirmed in the images that follow.
