Spotting scopes are designed to bring distant objects closer and usually offer a more stable foundation than binoculars as well as greater magnification.  This is why s potting scopes begin in magnification where conventional binoculars stop. The higher magnification offered by a spotting scope allows you to view objects that are well beyond the range of a conventional binocular. However, there are limits to magnification and two things determine how much magnification you can use in a spotting scope.

The first is the atmosphere.  Heat waves, dust, humidity, glare, wind and air currents all reduce image quality and the greater the magnification, the more drastic the reduction in image quality.  Because of this, very few locations allow you to use more than 60-80x during the day, so most spotting scopes stop at 60x.  The second major limitation of spotting scope magnification is the optical system of the spotting scope, itself.  Regardless of the model, there will always be some drop off in image quality as magnification goes up. This is determined largely by design and component quality.  Here is where you get what you pay for in a very visible way. Image quality deteriorates quickly as magnification increases with inexpensive spotting scopes, regardless of size or type.  Premium spotting scopes maintain consistent image quality, even at the highest magnification. 
 
So be prepared to pay if you want a spotting scope that is as sharp at 60x as it is at 20x. Only a handful of very expensive spotting scopes are capable of this, and this is what eurooptic.com specializes in, premium optics. We offer the best spotting scopes from the premier spotting scope manufacturers such as:  Zeiss Spotting Scopes,   Leica Spotting Scopes, Swarovski Spotting Scopes, Carl Zeiss Hensoldt Spotting Scopes, and Meopta Spotting Scopes.  So if what you want or need demands the highest performance available, you have come to the right place.   Our spotting scopes are ideally suited for activities as long distance bird and whale watching, nature studies, telephotography, hunting and target shooting.
