People that love to go birdwatching have for years on end used binoculars UK to be able to clearly observe their feathered friends that are far away or when they don’t want to venture too close to those that are nesting. However, many times bird watchers get a shock of their lives when they put binoculars aside and decide to try a spotting scope. A spotting scope can play such a huge role because apart from making it easy for someone to locate a faraway bird, it comes in handy when you are dealing with some of those shy and highly sensitive species such as hawks, waterfowls and shorebirds in such a way that they sometimes can put your spotting scope UK to shame. Just like with binoculars UK, there are design and optical features you should have in mind when buying a spotting scope. |
Magnification power: You clearly say that a spotting scope is a medium range telescope that has magnification power of between 15x and 60x. In order for you to adjust magnification you will make use of interchangeable fixed length eyepieces or a single zoom eyepiece. If you are going to use a spotting scope, you are better off starting using a lower setting as you start scanning for a bird before you adjust to higher power once you have located one.
Zoom lenses: You only require a single adjustment for you to adjust the zoom lens of your spotting scope and with that one adjustment you will have changed magnification form 20x to 60x. The zoom lens offers a clear advantage for bird watchers because of the ability to shift focus fast when looking for details. The only other thing that you want to know about zoom lenses is that they may not gather any light and, as a result, when you increase magnification using the zoom lens you get a less light, a narrower field of view as well as more vibration that reduces stability.
Glass quality: You should expect any top quality spotting scope to come with extra-low dispersion (ED) or fluorite coated high density (HD) glass. You only need to peek though the eyepieces to realize that there is world of difference between the two. Always try as much as possible to go for the higher quality but which will definitely be higher priced.
Light-gathering capacity: Just like binoculars UK, the capacity of the spotting scope to gather light is determined by the size of the objective lens; the value is likely to be anywhere between 50 mm and 100 mm. Even though larger objective lenses provide for brighter images, you will be forced to carry a larger spotting scope that is more cumbersome to pack and carry along.
