Over the last few hundred years, the telescope has been an instrument which has allowed the heavens to come into our doorstep. Single scopes or spotting scopes, for example, are often used for hunting and bird watching.
The first thing to know about a compact binocular is that it is two small telescopes mechanically linked together. When choosing a night binocular first decide what you are going to use it for. A lot of binoculars are ruined when dropped accidentally.
The latest binoculars come with attached lens protectors so that you can use them year round, regardless of time, climate, or season. In order to define the quality performance of their products, binocular makers present the field of view in mathematical conversions that show a variance of fields. Monoculars meant as a toy for children have magnifications of only three or four times and they are very cheap.
Another popular feature that has been available on opera glasses is permanent focus. Nevertheless, the capabilities of binoculars appeal to both groups as they choose equipment that best fits their needs.
