Angled vs straight spotting scopes: which is best for birding?

When it comes to bird watching, having the right equipment can make all the difference. Whether you’re just starting out or are a seasoned pro, choosing the right spotting scope is essential for getting the most out of your bird watching experience.

Spotting scopes for bird watching can be divided into two main types. For some people an angled spotting scope makes more sense, while others swear by straight spotting scopes.

So which is better? Let’s take a look at the pros and cons of each. The decision of which type of scope to choose is based on personal preference according to the kind of bird watching you want to do.

How to decide between angled vs straight spotting scope: main considerations

What type of birds do you like to observe?

Will they be mobile and fast-moving?
Slow and easy to predict?

What kind of environment are they in?

Level or steep terrain?
Windy or wet?
Coastal areas and open spaces?
Marine watching?

Where are the birds relative to your position?

Level with you, higher than you, directly overhead?
Will you be looking at hedgerows or over reed beds in marshes or lagoons?

What position will you be in?

Are you more comfortable sitting or standing?
Will you be birding from a vehicle?
Do you have back or neck problems?

What is the main difference between angled and straight scopes?

The two types of spotting scopes actually have a lot of similarities. Angled and straight scopes both perform the same main function, which is to give you a close-up view of wildlife in the distance.

When it comes to the main considerations like magnification, objective lens size and field of view, the two types of spotting scope are essentially equal and give the same image. Both configurations are available in the same ranges of lens size, which dictate the field of view and close range distance.

Structure changes the path of light

Their only difference is structure. This can be easily seen at the rear of the instrument and indicates how the spotting scope directs the path of light through the body of the instrument.

On straight spotting scopes, the eyepiece and objective lens are aligned with each other and are parallel to the ground.

On an angled scope, the adjustable eyepiece is at an angle in relation to the objective lens. The angle usually ranges between 45 to 90 degrees, so the body of an angled spotting scope curves to accommodate this configuration.

Straight vs angled spotting scopes: size and weight comparison

In general, when it comes to size and weight there is little difference between them. This also goes for other areas in their specifications – like the visibility and price tag.

If we compare the 65mm ATX and the 65mm STX from Swarovski, the weight difference is just over an ounce, with the angled spotting scope being marginally heavier. Both lengths are within 0.2 of an inch of each other. Their close focus distance is the same, at 9.8 feet and their field of view is also the same at 126 to 81 feet at 1,000 yards.

Comparing the 27-60×85 Razor HDs from Vortex, the straight spotting scope is a touch longer, at just over 16 inches, while the angled spotting scope is only 15 and a half.

Their weights are the same as is the visibility on each model. Field of view is 117 to 68 feet at 1,000 yards, with the close focus distance 16.4 feet.

Straight vs angled spotting scopes: ease of use comparison

The main reason that many bird watchers prefer the angled spotting scope is comfort. Most people find it more comfortable to look down into a scope because it is more comfortable for the neck when viewing for long periods.

In circumstances where bird watchers need to look up – when tracking migrating birds, or raptors soaring overhead, for instance – an angled spotting scope is much less likely to cause neck fatigue than a straight spotting scope.

For multiple people sharing viewing equipment, an angled scope can be set up on a tripod at a height that is suitable for the shortest person in the group. It is comparatively easy for other birders just to lean over and share the scope at this height. Generally speaking, an angled eyepiece is more preferable for tall people.

With straight spotting scopes the tripod would require readjustment for each different user. The best viewing angle requires that their eye is in an exact straight line with the eye piece of a straight scope.

Will you use a scope alongside binoculars?

Another advantage of the slightly lower position of the angled spotting scope on a tripod is if the scope is being used in combination with binoculars. In this case it is easier to scan the landscape just by looking over the scope rather than needing to move and change position to the side of the tripod.

Beginner birders, however, may find it easier to spot and track birds with the straight spotting scope. Since the straight eyepiece and straight tube point in a direct line toward the target it is more intuitive to aim the instrument in the required direction.

Binoculars vs spotting scope: which is better for birding?

Straight vs angled spotting scope: image quality comparison

As we have already seen, the specifications are virtually the same across straight spotting scopes or angled spotting scopes of the same range from the same manufacturer. Given that both models will use the same optic quality of components, in terms of the prism and lens glass and their coatings, image standard will be the same.

The image quality may differ because of how the spotting scopes are set up on the tripod. For an angled spotter, the tripod doesn’t need to extend as high. In many cases the center post does not need to be extended either.

This means that the overall stability of the tripod will be better due to their lower center of gravity. Therefore the images seen through angled scopes may be more steady, less subject to image shake. In comparison, people might find the straight spotting scope unstable.

Because it is smaller, a shorter tripod is also lighter, reducing the overall weight that needs to be carried. Its increased stability also decreases the likelihood of it getting overturned and damaged.

Straight vs angled spotting scope: weather considerations

Since the angled spotting scopes can be used on shorter tripods, the tripod will be more stable and provide better images which is more noticeable in windy conditions. A taller tripod makes images more prone to blurriness.

In rainy or snowy weather, the ocular lens of an angled spotting scope is more prone to gathering liquid. Water can collect in the eyepiece if you are not looking through it, meaning that you need to cover it or replace the lens cap so that it doesn’t fill up.

The lenses of angled spotting scopes are generally more exposed than the straight spotting scope. They can therefore collect dew even on fine early mornings. Dust seems less likely to settle on a straight spotting scope than on an angled one.

Straight vs angled spotting scope: digiscoping comparison

Many people find that it is easier to set up digiscoping with an angled spotting scope. The main reason for this is the angle of the screen of the phone or camera. Instead of being level, the screen is angled upwards. For most cases, this is easier to see and use.

Digiscoping is better from a more stable base. Because an angled scope is usually combined with a lower tripod, this is more suitable for digiscoping for a higher quality image.

Straight vs angled spotting scope: use with binoculars

Many birders use binoculars in conjunction with a spotting scope. They use the naked eye to find the bird, binoculars for target acquisition and to track its position, and a scope for a closer view.

If you are using higher power binoculars, such as 12x, then they may need to be mounted on a tripod. When needing to switch between binoculars on the tripod to a spotting scope, it is easier if you have a straight spotting scope.

The line of sight of an angled spotting scope is a few inches lower than the naked eye or what you would see with binoculars, making it necessary to adjust the tripod to this slightly lower height too. This extra time taken to change the height can mean that you miss the bird or move the sight line off it entirely.

Straight vs angled spotting scope: comparison of birding uses

An angled spotting scope is better for bird watching when:

• Looking at an upward angle, for example, at raptors soaring
• Tracking overhead migratory flight paths
• Looking at nesting birds at cliffs or perched in tall trees
• On hilly terrain, like a canyon
• Digiscoping from a lower tripod = a more stable base

A straight scope is better for bird watching when:

• Looking at a downward angle
• Using from a ridgeline or tree stand
• Tracking fast-moving birds and quick target acquisition
• Using from a hide
• Using in confined spaces, such as from a vehicle – as long as there is enough space in your car!
• Digiscoping from car mounts

Straight spotting scope vs angled spotting scope: best uses for bird watching

If bird watchers are aiming to see birds that are going to be high up, then angled eyepieces are more comfortable. This applies to situations where birders might be observing birds flying overhead or settled high up on cliffs or in tree canopies.

It is of course possible to use a straight spotter in these circumstances. But to get a good view it’s necessary to get down lower to get the straight spotting scope angled directly at the target.

For the best results when watching birds flying or in high locations with a straight scope, a tall tripod makes sense. This adds to the bulk and weight of the gear to transport to the birding site.

Conversely, when watching birds at a lower position, like looking down from the top of a cliff to an inaccessible coastline, for example, then scopes will be pitched at a steeper angle.

Straight spotters suit downhill

When looking downhill, it is easier to get a straight spotting scope angled correctly. When angled spotters are pointed down at a sharper angle like this, it can present problems. The tripod needs to be shortened significantly in order to be able to look down into the eyepiece. This adjustment can mean losing sight of the subject.

Plus, the user needs to either be sufficiently tall to line up their eye correctly with the eyepiece, or to be perched up on a chair or rock or some such to reach the eyepiece.

The line of sight of a straight scope is more in line with the naked eye, being the same as at eye level. An angled spotting scope, however, projects an image a few inches lower than what the eye sees.

With this in mind, if the angle of view is very tight, a straight spotting scope may be advantageous. For example, when a bird is located right at the edge of view above a line of fencing or plants, or if you are watching from a tree stand, a lower line of sight may mean the bird is out of view through an angled spotting scope.

Straight vs angled scope: which is best for car use?

For birdwatchers who operate from inside their car, a straight spotting scope is more convenient. It is easier to use with car mount. The arc in which you can use it is wider than with an angled spotting scope and you don’t need to adjust the collar to be able to look through the eyepiece.

The exception to this is when looking up from a car window mount. In this case it is easier to use an angled scope and adjust the eyepiece, rather than trying to get yourself in a straight line with the eyepiece on a straight spotting scope. Discount that if you don’t mind some minor contortions, though!

Advantages and disadvantages of an angled spotting scope

Pros of angled scopes

• Neck relief – more ergonomic and comfortable for longer viewing, especially from a standing position
• Easier to share with other people of different heights
• Higher eye point allows for a shorter tripod
• Smaller tripod = lighter and more convenient to carry
• Steadier images as tripod can stay unextended (better in windy conditions)
• Can be easier to bird watch while standing up
• Better for digiscoping
• Better for spotting birds positioned much higher or lower than the viewer

Cons of angled scopes

• Takes more practice to aim and find the bird
• Eyepiece is more exposed to rain or snow
• Less easy to use in the car (need to adjust the collar)
• Line of sight is slightly lower than eye level
• More challenging to use looking down steep hills
• Less suitable to use in conjunction with binoculars (you need to change position or tripod height)
• Shape makes packing the scope more awkward

Pros of a straight spotting scope

• Easier to aim – faster target acquisition in general and better for beginners to learn
• Easier to track moving targets
• Same line of sight as the naked eye – no need to shift position
• Less strain on your neck for level viewing
• Easier to use while seated or in a prone position
• Easier for looking downhill or at birds some distance below you
• More suited to use from a vehicle (including digiscoping from a car)
• Better in wet weather as eyepiece doesn’t collect water or snow
• Quicker switch from tripod-mounted binoculars to scope
• Less awkward shape to be fitted in bag

Cons of a straight spotting scope

• Viewer has to move around more to see directly into straight eye piece
• Less comfortable for general viewing (especially use while standing)
• Taller tripod = more image shake (most noticeable in wind)
• Extended tripod = more visible
• Larger tripod = more difficult to carry

Angled vs straight spotting scope: which is best for you?

In summary, angled scopes have more stability because they are used with a tripod set up at a lower height. Many people consider that they are better for digiscoping.

When considering an angled vs straight spotting scope in terms of weight, price and optical performance, there is little difference. It is easier to share an angled scope with other people but they are more marginally less convenient to carry due to their shape. This is the compromise for a spotting scope that is more comfortable for extended use, with less neck strain.

Are you a beginner or experienced birder?

Beginners may find a straight scope more intuitive to use because it is in line with the eyes’ natural viewing angle. Some people find that a straight one is easier to use to track fast-moving birds, while others consider an angled scope to have better manoeuvrability.

A straight scope is better suited to inclement weather because it is less likely to mist up or accumulate water in the eyepiece. The straight scope is easier to switch between scope and binoculars if you use both instruments in combination.

For those who want the best of both types of spotting scope and have a healthy budget, consider investing in a scope from Swarovski. This well established company has developed a modular scope you can switch between angled vs straight spotting scope by changing the rear module.
