Usually the people who use spotting scopes demand high quality optics that performs perfectly under any type of weather conditions. Today a decent scope is considered as standard equipment for common bird watchers. The better the optics, greater is the clarity and demand. Selecting the right model for matching your needs and budgets is very important.
Types of scopes
There are generally two types of spotting scopes. They are:
Dedicated birding scope- For heavy field use. They have\ the mechanism of Bird Watching Momoculars as well as prisms sheltered inside the body scope.
Astronomical scopes-They have the focusing mechanisms and erecting prisms outside the body scope that will enable you to personalize the back end.
Compact and full size scopes
Any optic above10X is usually difficult to use without any support. It gets shaky at high magnification level. At the low end of the magnification range, this scope can be rested on a pack. The solution to this problem has always been a lightweight monopod, which doubles as a shooting rest.
Whether you choose the Compact or a full-size model, it depends on your individual needs. Usually a full size scope is better but compact ones are also useful because they are easy to carry and are light weighted.
Monoculars
A bird watching monocular is a customized version of refracting telescope. The weight and volume are less than half of those binoculars with related optical properties, making it easy to carry. Monoculars produce 2-d imagery, while binoculars add perception of depth that is 3d effect. Monoculars are sometimes called as telescopes.
Bird watching monoculars are designed to withstand the hardest of conditions and offer great viewing facility. It is made up of objective lenses and smaller prisms to decrease weight but give awesome viewing.
