Binoculars magnify the image of a distant object so that it looks much closer than it actually is. Bird watching binoculars are one of the critical pieces of equipment bird watchers carry.
The same problem is faced while using telescopes hence many people prefer binoculars instead of monoculars or telescopes. The bigger the aperture the more light is captured so the brighter and clearer the image will be. Digital binoculars are a cheap alternative, and can be picked up for considerably less money, and usually have a built-in camera.
There are giant binoculars available with higher magnifications and apertures which are designed for astronomy use but you will certainly need a sturdy tripod or mount to use them. If the lens cloth is not a one-time use variety, it should be cleaned lightly and thoroughly before each use and should be kept in a clean and dust-free bag. In the event of an accident, you will be glad that you chose rugged and waterproof binoculars.
Mars and Venus on the horizon are a whole different picture when you can magnify your own vision. Binoculars are a key piece of equipment outdoors.
