Spotting Scope Best Practices
Long-views are used when the magnification is greater than or equal to that provided by the binoculars. They are widely used for birdwatching, observing wildlife, landscapes and other objects at a great distance. Much of the terminology and technical specifications specific to the length-views are similar to the binoculars. For example, a 20-60x82-long view has a zoom magnification range of 20-60x (20 to 60 times greater than the size of an image as would be seen with the naked eye) with a lens diameter of 82 mm. The significant increase in magnification can lead you far beyond the capabilities of conventional binoculars. That said, it should be kept in mind two factors, the atmosphere and the optical system of the spotted sight. Heavy air, dust, moisture, glare, wind and draughts during the day can all reduce the quality of the image. The larger the magnification, the more important the reduction in image quality will be. Few locations allow you to use more than 60 to 80 times ...
