Spotting scopes are a mix of binoculars and telescopes. You get the portability of standard binoculars as well as the longer-range viewing capability of a telescope. Spotting scopes offer high definition magnification for longer distances, and are excellent optical devices for birding or hunting. With so many choices on the market, it can be a daunting task to find the best spotting scopes.
To help you out, we've listed some of the things to look for:
Spotting Scope Magnification: The recommended magnification for birding or hunting should be between 20X and 40X. This will give you a good field of view, as well as sufficient image brightness.
The Objective Lens or Aperture: The objective lens or aperture relates directly to the size of the magnification. The larger the diameter of the scope's objective lens, the more light and greater clarity your object image. If you consider a spotting scope with an aperture of 50mm-80mm, it will do well for most situations.
Exit Pupil: The exit pupil is the diameter of light visible through the scope's eyepiece. Go for an exit pupil that is 1.33mm and above. Otherwise the visible light visible will be so low, that your scope will hardly pick up anything.
Eyepieces: There are two types to choose from:
1. interchangeable fixed and single zoom - or
2. variable. The first is best for panorama viewing, because the fixed gives a wider field of view. The second, offers magnification from low to high, allowing for a wide field of view but then also being able to focus deep.
If you're looking for the best spotting scopes, you won't go wrong with Bushnell or Celestron or Leupold. They've been crafting quality optical gear for quite a while you can be assured that quality is not an issue!
