Magnification and Lens Power: Deciphering the Numbers
Understanding the Code
The specifications of a spotting scope can seem a bit like a code at first glance, so let’s break down the “20x60x60” designation. The first number, “20x,” represents the magnification power. This means that objects viewed through the scope appear twenty times closer than they would with the naked eye. This is particularly advantageous for long-distance viewing, allowing you to see details that would otherwise be obscured.
Objective Lens and Light Gathering
The subsequent number, “60,” refers to the size of the objective lens, measured in millimeters. The objective lens is the primary lens that gathers light and determines the brightness and clarity of the image. A 60mm objective lens is considered a decent size for a spotting scope, providing a good balance between light gathering and portability. A larger objective lens generally lets in more light, resulting in a brighter image, especially in lower light conditions.
Zooming In
The variable zoom feature, which offers a magnification range of 20x to 60x, is another key aspect of this spotting scope. This allows users to adjust the magnification based on their needs. At the lower end (20x), the field of view is wider, making it easier to locate and track moving targets. As you increase the magnification towards 60x, the image becomes larger, revealing finer details, but the field of view narrows, and image brightness can decrease somewhat.
Optical Clarity: Coatings and Construction
Lens Coatings for a Better View
The optical quality of a spotting scope is crucial to its performance. The Bushnell 20x60x60 often features lens coatings designed to improve image brightness, contrast, and color fidelity. These coatings work by reducing light reflection off the lens surfaces, allowing more light to pass through to the eyepiece. While the specific type of coating can vary depending on the exact model, it’s important to note that such coatings are essential for a clear and bright image.
The Prism System
The prism system is another key element of the optical design. The Bushnell 20x60x60 often employs a Porro prism system, which is known for its ability to produce a bright and sharp image. The Porro prism design also contributes to the overall size and shape of the scope. Although it can be a bit bulky, it offers great image quality.
Build Quality for the Outdoors
Beyond the lenses, the construction plays a significant role in the scope’s durability and performance. The outer body of the scope is typically constructed from materials designed to withstand the rigors of outdoor use. Rubber armoring, common on many Bushnell scopes, provides a secure grip and protects the scope from bumps and scratches. This rugged construction is essential for any scope that will be used in various outdoor environments. Water resistance is another crucial feature, ensuring the scope remains functional even in wet conditions. Many models offer a degree of water resistance or even water-proofing, protecting the internal components from moisture damage. Furthermore, fog-proofing, usually achieved by purging the scope with nitrogen, prevents internal fogging caused by temperature changes, ensuring a clear view even in challenging weather conditions.
Eyepiece Options
The eyepiece design also contributes to the overall viewing experience. Some Bushnell spotting scopes feature an angled eyepiece, which is favored by many birdwatchers and those who spend extended periods observing targets at a high angle. Others have a straight eyepiece, which is generally preferred for target shooting and situations where a straight line of sight is advantageous. The choice of eyepiece style often comes down to personal preference and the intended use of the scope.
Focusing for Precision
Fine-tuning Your View
A smooth and precise focusing mechanism is fundamental for a quality spotting scope. The Bushnell 20x60x60 typically incorporates a focusing knob, allowing users to fine-tune the image sharpness. The ease and accuracy of the focus mechanism are important for obtaining a clear image, especially at higher magnifications. The focus knob should be easy to locate and operate, even with gloves on, and provide a smooth, precise adjustment throughout the focusing range. Some models include both a coarse and a fine focus adjustment, allowing for rapid focusing and fine-tuning.
Additional Features and Accessories
Tripod Compatibility
Beyond the core optical and construction elements, the Bushnell 20x60x60 may include a number of features that enhance its usability. Many scopes are designed to be mounted on a tripod, providing a stable viewing platform. A built-in tripod adapter is standard, allowing users to quickly and easily attach the scope to a tripod. This is particularly important at higher magnifications where even slight hand movements can cause the image to shake.
Sunshade for Glare Reduction
A sunshade is another feature that can significantly improve the viewing experience, especially in bright sunlight. The sunshade extends out from the objective lens, reducing glare and improving image contrast. This can be especially useful when viewing objects against a bright background.
Expand Your Capabilities
The availability of optional accessories can also broaden the scope’s functionality. Digiscoping adapters, for example, allow users to connect a camera to the scope, enabling them to capture images and videos through the scope. Other accessories, like carrying cases and lens cleaning kits, can further enhance the user’s experience and protect the scope.
Assessing the Viewing Experience
Brightness and Clarity
The true test of a spotting scope lies in its performance. Let’s examine the key aspects of the viewing experience. Assessing the brightness and clarity of the image is important. This involves evaluating the scope’s performance in various lighting conditions, from bright daylight to low light environments. The goal is to determine how well the scope gathers light and delivers a clear, bright image. A scope with good light-gathering ability will reveal more detail, especially in shadowed areas.
Color Fidelity and Distortion
Examining how accurately the scope reproduces colors is vital. Color fidelity is crucial for birdwatching and wildlife observation, as it allows for accurate identification of species. Image distortion, such as chromatic aberration (color fringing) and edge distortion, can detract from the viewing experience. Chromatic aberration appears as colored halos around the edges of objects, while edge distortion can cause the image to appear warped at the edges.
The Field of View
The field of view, the area visible through the scope at a given distance, is another critical factor. A wider field of view is beneficial for quickly locating and tracking moving targets. However, as magnification increases, the field of view typically narrows. The trade-off between magnification and field of view should be considered depending on the intended use of the scope.
Comfort and Eye Relief
Eye relief, the distance between the eyepiece and the user’s eye, is important for comfortable viewing. Sufficient eye relief allows users to see the entire field of view without having to press their eye directly against the eyepiece. This is particularly important for those who wear eyeglasses, as it allows them to use the scope without removing their glasses.
The Upsides and Downsides
The Pros
Like all products, the Bushnell 20x60x60 spotting scope has its strengths and weaknesses. The advantages of this scope can include its relatively affordable price point. Its often rugged construction can ensure durability in various conditions. For some users, the image quality provided at the lower end of the magnification range is great. It’s also fairly easy to use, which makes it a good option for beginners.
Areas for Improvement
While it has positive aspects, it is not a perfect scope. The image quality at maximum zoom may suffer. The overall optical performance may not match that of more expensive, premium spotting scopes. Also, the weight and size may pose a challenge.
