Scope Binoculars

You may have been told that seeking out a scope binoculars  for birding, hunting, and other wildlife viewing and observing is your best bet if you truly want to maximize your outdoor experience. Scope binoculars are similar to both binoculars and telescopes, combining the convenient portability of the standard binoculars, with the longer-range viewing capabilities of the star-gazing telescope. Scope binoculars can give you the high definition magnification capabilities required from longer distances, and so are the perfect optical device for your birding or hunting adventure. However, sometimes it can be quite overwhelming trying to find the best spotting scope, sifting through technical jargon and industry terms. That's why we have outlined the most important aspects of the spotting scope, definitions of specifications, and recommendations on what to look for.

Magnification: Finding the best magnification in your prospective spotting scope relies on how large the objective lens is; i.e. the higher the magnification, the larger the objective lens should be for resolute image quality. The best magnification for birding/hunting endeavors should be between 20X and 40X. This range offers a good field of view, as well as necessary image brightness.

Objective Lens or Aperture: As previously discussed, the objective lens or aperture is directly related to the size of the magnification. The larger the diameter of the objective lens, the more light and subsequent clarity your object will receive. Depending on where you will be using your spotting scope, you'll want to find a scope with an aperture of 50mm-80mm.

Exit Pupil: The exit pupil is very similar to, and works in conjunction with, the objective lens. It is the diameter of light visible through the eyepiece. If these specs are not available at the time, just divide the objective lens specs by the magnification, and this will give you the exit pupil dimension. Make sure your new spotting scope has an exit pupil that isn't below 1.33mm, otherwise the light visible will be so minimal that seeing anything in any conditions will be almost impossible.

Eyepieces: Eyepieces help with your magnification depending on the type you prefer in any given situation. They come in two basic types: interchangeable fixed and single zoom or variable. The former is best applied for mountain and ocean panorama viewing, as the fixed will give you a wider field of view. The latter offers a varying magnification from low to high, which enables the viewer to both have a wider field of view but then also be able to focus in with higher magnification.

Field of View: The field of view is basically the width of the area visible 1000 yards from the viewer. It is inversely proportional to the magnification: the larger the magnification, the narrower the field of view. A fixed eyepiece will give you a wider field of view, and the variable eyepiece will give you both wide field of view and more intense magnification. Depending on your outdoor hobby, you should probably opt for a wider field of view (fixed eyepiece) if your scoping is predominantly deals with panorama; and a combination field of view/magnification (single zoom or variable eyepiece) for surveying both panorama and object detail.

Spotting Scopes

Roy C. Smallwood 3rd asked:


Spotting Scopes

You’ve been birding for some time and developed a degree of expertise. You may have built a good life list. Now you want to expand that list and ensure quality sightings at the same time. Binoculars served you well at closer ranges, but what about the birds across the water or on the mud flats, or farther across the prairie, or high in the sky? You are ready for new gear: a spotting scope.

As it is with binoculars, so it is with scopes. One can spend any amount. Often, manufacturers try to accomplish being inexpensive and being lightweight at the same time. Sometimes, this leads to scopes which are not well proofed for water or fog and are not as rugged. Still, recent trends have brought down the price to more affordable levels. Consequently, spotting scopes are not only for the elite, but are becoming both essential and accessible equipment for the avid birder.

The first decision is the eye piece, also know as the ocular. Really, this is two decisions in one. First do you want it configured straight through sited (ST) or angular (AN)? Straight through may make it easier to find birds because it works just like your binoculars. Angular appeals to some because it may be less a strain on the back and neck. If you are the sole user of the scope, ST may be the way to go. If you tend to share with several people when birding, you may wish to consider AN. Secondly, you have a choice of a fixed or variable magnification. Many believe it best to stick with a fixed magnification of 20x or 30x--the larger the magnification the greater the light distortion. Variable magnifications typically are 15x-45x or 20x-60x. You should use the smaller magnification in the range to locate the bird and ramp up to gain more detail. As you ramp up, less light will be let in accompanied by a narrower field of view.

The next decision is the objective lens. These define the field of view and are best if at least 60 mm. Larger objective lenses gather more light as well as allowing a greater field of view. The material used for the lens is important, too. The more expensive scopes have a special type of glass in them call ED, which stands for extra-low dispersion. ED enhances light gathering and corrects for chromatic aberration.

Finally, don’t neglect the support for your scope. Rigid, mid-weight tripods are best. Tripods need to be sturdy and easily adjustable. Consider a tripod with flip locks for secure and quick adjustments.

The acquisition of a quality spotting scope will enhance your experience and enjoyment of the great outdoors.
