Simply, a Best spotting scope is a small refractor or catadioptric astronomical telescope with erect image. The spotting scope mounts to a photographic/ video tripod for stability while using it.
Any spotting scope has two basic functions:
1.To gather more light than the unaided human eye does
2.To enlarge the image of what you’re looking at, normally at long distances
However, a spotting scope is much more than a basic definition. A spotting scope can:
-Open up new vistas of learning and pleasure to your life
-Create excitement with new discoveries Help while hunting when searching terrain for game at long distances Convenience for target shooting to evaluate your results on the targets Add new dimensions to whatever you enjoy looking at Expand hobbies to gain more fulfillment like birding, hunting, wildlife observation and astronomy Aid in your appreciation of the worldSpotting scopes come in a variety of magnifications by using eyepieces. Some are of fixed power and most of these are in a range from 12x up to 30x. Others have interchangeable eyepieces with different powers (10x up to 60x normally), and others are variable (zoom) models which are by far the most popular (ranges from 12 to 40x, 15 to 45x, and 20 to 60x, and other powers). The variable models are quick to go to high power or anywhere in between.
Typical objective lens sizes range from 30mm to 100mm or larger and you will find numerous models of varying sizes and magnification ranges. The most popular models are with 60mm and 80mm objective lenses.
Lower powers will give you the brightest images with the widest field of view. This is great in scanning distant objects. Higher powers will allow you to see more details. For example, when hunting you can see details at low powers that you cannot see with binoculars and you can see hidden game, and see further details at higher powers.
Spotting scopes come mainly in one of two styles – straight through (where you look straight through the eyepiece in a straight line) and in an angled view (where you look at the object at an angle of 45 °). The choice between the two is a personal one determined by what type of viewing you will be doing and many other factors. The angled types are the most popular and are fine for finding objects after you get used to the spotting scope. The angled scopes are easier to use when two or more people are sharing the spotting scope on a tripod rather than having a pain in your neck or constantly changing the tripod height.
Most spotting scopes are adaptable for taking images (snapshots or video) with the proper adapters – called digiscoping. There are various adapters required depending on your particular spotting scope to use point and shoot digital cameras, SLR cameras, and DSLR cameras. Some digital spotting scopes have built-in cameras.
There are hybrids to what most people think are spotting scopes. Tele Vue turns astronomical systems into excellent refractor spotting scopes and Celestron offers very good Maksutov and Schmidt-Cassegrain spotting scopes all of which look different.
