A telescope is an instrument that makes it possible to look at stars and the planets from the comfort of your own home. You can extend the life of these coatings by using lens cleaner before and after each use. If you are planning on using your binoculars for birdwatching you want to look for a pair that is designed with good image quality. Nowadays, binocuars are now made smaller and lighter than before.
The bigger the aperture the more light is captured so the brighter and clearer the image will be. A larger objective lens makes sense during low light conditions, since it can capture more of the available light. Many binoculars have eyepieces that fold in and out.
