Definition
- spotting scope
- A spotting scope is a modification of an astronomical telescope. However, there are some major differences. A spotting scope is much smaller than a telescope and is mainly used for more low magnification vision. Another very radical difference is that a spotting scope always produces an upright image whereas a telescope usually produces an upside down one. The main plus point here for a spotting scope is that it is water proof and fog proof- a feature hardly present in astronomical telescopes.
Scope Uses and Applications
Spotting scopes are mainly used for viewing distant object like while bird watching, hunting, for surveillance at crime scenes and wildlife observations. In addition to that a spotting scope can also be used to take pictures of these distant objects while observing them. Also a spotting scope can also be used to hit a target accurately in archery and shooting with pistols or rifles.
Scope Numbers
A spotting scope usually consists of three numbers, the first two specifying the magnification range and the third one, the size of the front lens.
Scope Magnification
The magnification of a spotting scope is far better as compared to a regular binocular. However, the image quality deteriorates as the magnification increases. Dust, moisture and dirt act as obstacles to perfect image quality. The ideal range at which the images are pretty clear is 30X to 40X. Rarely can a spotting scope be used for magnifications higher than 60X.
Objective Size
The quality of the image delivered by the spotting scope depends largely on the size of the objective lens. The larger the lens the better is the image quality. However, if the large lens is made of inferior quality glass then a smaller lens may actually perform better than it. So to improve the quality of the images especially at higher magnifications it is best to go for special quality glass like ED Glass, APO Glass, etc.
Close Focus
Close focusing, although not always needed is a useful feature if it has a close focus of less than 20 feet.
Image Quality
The level of image quality is directly proportional to the price and make of the spotting scope. The quality delivered by an exceptionally good spotting scope and that of a mediocre one will differ hugely. So if you want a good performance from your spotting scope you must invest a substantial amount in it.
Waterproofing
Although waterproofing is not present in all spotting scopes and is not an absolutely essential requirement, it pays to have a waterproof spotting scope. The seal for waterproofing not only protects it from water but also from dust and dirt increasing the longevity of the device.
Eye Pieces
The eyepiece is the most important part of this optical device and it pays to invest in a good one. A high quality eye piece not only provides eye relief but also contributes a lot to the image quality. It is best to go for an eyepiece with zoom in it as it not only helps in changing magnifications faster but also works well in rough weather.
Camera Adapters
Not all spotting scopes come with a camera. In that case you can easily attach a digital point to your spotting scope via the camera adapters by Zhumell and Barska to use your device to take photographs.
