Telescope is used when needed or wanted more magnification than binoculars provide and is widely used for bird watching, wildlife viewing and scenery and other objects at great distances. Most of the technical specifications and terms is to identify a range similar to Binoculars. For example, 20-60×82 telescope has a zoom range 20-60x magnification (20 to 60 times larger than the size of the image as will be seen with the naked eye) with a diameter of 82mm front lens.
A significant increase in magnification can take you far beyond the capabilities of conventional binoculars. However, two factors, the atmosphere and the optics of the Spotting scopes observation, must be kept in mind. The weight of air, dust, and humidity, glare and wind and air currents during the day can all reduce the quality of the image and the magnification, the more drastic reduction in the quality image will be. Some places allow you to use more than 60-80x in daylight, so at least stop spot increased to 60x. The optical system of the observation Spotting scopes will affect magnification as well. As magnification increases, some reduction in image quality will be made regardless of the model. In key areas such as the old saying goes, you get what you pay for. So yes, if you want part of a clear-cut at a magnification of 60x 20x because it is less, so expect to pay more. Keep in mind that most used a spotting scope at low magnification, usually around 30x-40x. It’s more than enough for most applications and modeling all but the most expensive and cheapest is to produce a reasonable picture of the range of magnification.
