Since the dawn of time, man has looked up at the heavens and wondered the beauty it may contain. A telescope is a scientific optical instrument.
The best binoculars for astronomy use are 7 x 50 or larger. Boaters and those that enjoy the water will want the waterproof or fog proof models. Fortunately, the new weatherproof binoculars are fit for rough use.
The objective lenses are located on the end of the binoculars furthest away from your eye when viewing. How well your binoculars will serve you in low light conditions is described as twilight performance. 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 most cases, pocket binoculars are of prism roof design and the front lenses and the eyes come in a straight line; such binoculars are usually compact. Despite all of your preventive measures, there will come a time when your binoculars are damaged.
