The most effective recognizing scopes for birding: A patrons information

Without binoculars, we would miss so many birds, even in our own yards. With experience, a good binocular will let you identify most birds visible to the naked eye. Some think “bins” are all you need and consider a spotting scope unnecessary. That is true for backyard and forest birding. So, get binoculars first, then get a better pair of binoculars. 

Eventually, most birders will experience the need for a scope. For me, that was the year I started birding. When birding winter farm fields and the New Jersey shore, a scope view was often critical to clinch an ID. An ocean horizon, waterfowl on wide bays, shorebirds spread over mudflats, and orbital raptors challenge binoculars. Even if you can identify the bird with binoculars, you may feel dissatisfied. The feeling even has a name: “BVD,” or better view desired. A scope reduces both the “too far away” category and the BVD category. 

And the first view of even a common bird through a spotting scope can be a gasp-inducing “wow” moment. After birding 50 years, I find scoping a flock of winter ducks with the sun over my shoulder enjoying better-than-the-field-guide views is still heavenly. In the contemporary idiom, I am firmly on “Team scope!” 

But all the brands and models daunt the new buyer. Should I select an angled or straight scope? What are the pros and cons of a small objective or a large one? Are fixed-power eyepieces better than zoom? Is an ED (Extra-low Dispersion) objective worth the extra money? In this article, I offer guidance to those who are on the fence about scopes or wonder how to select one. 

We will look first at the pros and cons of straight and angled scopes. 

Straight scopes are easy to aim; just point them where you are looking! At eye-level height, you can see over plants/fences and get longer looks behind wave crests. They work well with a car window mount, and in rain, it is easier to keep the eyepiece dry. Downsides are that the eyepiece must be at your eye level, and it might be less stable at that height, which may require a larger tripod. If you lower the scope for a shorter person, it becomes uncomfortable for the taller users. To view the zenith, you must raise the scope above your head, crouch down low, or both. Lastly, with both eyes looking in the same direction, the non-scope eye tries to bring the horizon into focus, so most people will close the non-scope eye. This can lead to eye fatigue if you are scoping for hours.

An advantage of angled spotting scopes is that when you set the scope for the shortest person in the group, everyone else can use it too! Set below eye level, the tripod is more stable and less prone to tipping. With the 45° angled eyepiece, 60° above the horizon is in easy reach. A key advantage is that the scope eye focuses on a distant object, while the other eye looks at the ground nearby. It intrudes less, so long-term viewing is more relaxed, good for long-term scanning. Angled scopes have some potential downsides. Objects in the foreground may obscure your view, as you lose the advantage of height. You may need to rotate the barrel to keep the eyepiece dry in rain or snow. Depending on vehicle headroom, using a car window mount may require rotating the barrel 90°, which points the scope 45° from the direction you are looking.

But angled scopes have become so popular among birders that at Cape May Bird Observatory, they are all we stock, though we happily order straight scopes when asked. Some models are only available in angled versions, which takes one decision out of the equation for shoppers. 

Through the 1980s, zoom eyepieces were not particularly good. Fixed 22x or 30x wide-angle eyepieces were popular then and are still valid options today. But today’s zoom eyepieces are much better, and most scopes come with a zoom eyepiece by default. A zoom eyepiece allows easy scanning at low power and a fast increase in power when you see something of interest. Even entry-level scopes offer eyepieces that work well through the lower two-thirds of the range. Just do not expect to use the maximum magnification in any but the highest-quality optics. For most birders, an angled scope with a zoom eyepiece is the best choice: another decision down!

But what size should you get? Size, in this case, refers to the diameter of the objective lens. Spotting scopes range from 50mm to 85mm, and a few manufacturers go up to 88, 95, and even 115mm.

Astronomers know that when considering objective lens size, in terms of light-gathering ability, resolution, and high magnifications, the bigger, the better! That is true for spotting scopes for birding as well. But in astronomy, you move the telescope by car and set it up in one spot. Saturn is not going to be flushed by a Peregrine and lead you on a chase down the beach. 

But birds and birders are often on the move, and as you would expect, with increased size comes increased weight. Consider the scope and tripod together as a matched set. A stable support makes the scope usable at high magnifications. Depending on objective size, a combined scope plus tripod and head weighs between 5 (travel scopes only) and 13 pounds. Carbon fiber legs are lighter and quieter than aluminum but more expensive. Keep balance in mind; do not put a massive scope on a lightweight tripod. And do not skimp! A wobbly tripod will make the world’s best scope useless. The few years that a cheap tripod lasts may seem longer as you are tormented by shaky images and stiff, jerky panning. But a good tripod and head in the $200 and up range may serve you well for 20 years or even longer.

A smooth-panning video pan head is the default for effective scope use. Birders also often put a scope on a car-window mount (an inexpensive accessory), using the car as a blind. 

Scopes smaller than 60mm are promoted as “travel scopes.” They are lightweight and compact enough to fit in a carry-on for air travel or in a backpack if you are taking the subway and walking to the Central Park Reservoir. Some (e.g., the Celestron Hummingbird) can be hand-held at low power. Travel scopes can also be mounted on a monopod or a lightweight, compact tripod. While most will not provide the same brightness or resolution at high power as a “full-sized” scope, with the advantage of extreme portability, even an entry-level scope can reveal more details than the best binocular. A full-sized scope that never leaves the closet or trunk is useless. Travel scopes are a great alternative to no scope at all.

Also consider the glass quality. Better-quality glass is designated as ED, HD (High Definition), APO (Apochromatic), or other such terms. These all mean something similar: that at least one objective element has a fluoride compound in the glass and better-quality multi-coatings, though they are not all equal. ED/HD/APO all pay off at the higher end of the zoom range and are especially important if you plan on digiscoping (taking digital photos through your scope).

In deciding which size and objective quality will suit you best, be guided first by how you will use the scope and second by your stature and stamina. If you will mostly be taking it in and out of the car on an auto-tour route or walking a couple hundred feet to an overlook, then size and weight do not matter. Go full-size! If it is important for you to be able to ID storm-borne seabirds, you will be better served by a scope of 80mm or more with ED glass. 

But some birders may regularly hike a mile and a half up to a mountain hawk watch with a 500-foot elevation gain, while others love trudging several miles on a beach. And maybe you also carry a DSLR with a 150-600mm lens, plus a fanny pack with a water bottle. In this situation weight will certainly be an issue and you might prefer either a 65mm or even an under-60mm travel scope.
