Numerous designs and optical features can be seen in scopes in the current market. However, some primary features are a must when selecting best spotting scopes.

Let’s take a look at features of best spotting scopes.

Magnification

Spotting scopes happen to be medium-range telescopes. They arrive with a 15x-60x range of magnification power. To vary the magnification power, they come as a single zoom eyepiece or even as interchangeable eyepieces (having fixed –length).

Lenses for Zooming

Zoom lenses can vary from 20x magnification power to 60x power in just one alteration. These come in handy when it comes to bird watching. However, they don’t offer any advantage as camera lenses because these lenses can’t gather light.

Quality of the glass

High-level scope lenses are created using either extra-low dispersion (ED) or high density (HD) glass. Some of them are made using fluorite-coated glass as well. These scopes offer you enhanced image clarity and better brightness. Based on the type of birding you intend to do, you can decide on either opting for a high-quality glass or sticking to standard glass.

The capability of gathering light

The light-gathering ability of any spotting scope is determined by the dimensions of the objective lens. This value generally lies around the 50-100 mm range. The Larger the objective lenses, the heavier the scopes.

Placing eyepiece

Eyepiece placement is one of the factors to be considered while choosing a spotting scope. Some models offer eyepieces designed for straight-through viewing, whereas others offer 45deg angled eyepiece.

Relief to the eye

This factor is considered by individuals who wear eyeglasses. Longer eye relief provides you with an entire field of view. The appropriate value usually lies in between 12–15 mm range. Some of the scopes come with portable rubber eyecups too.

Focus

There are two forms of focusing on spotting scopes. One form involves a small focus knob being placed on the top of the scope close to the eyepiece. The other form is configured in such a way that the whole barrel of the scope is knurled with a focusing collar; this is done to create a sharper image. The individual’s hand size, as well as the skill, can be a problem, in this case, therefore perform each style to choose your preference.

Conclusion

In the event when you’re going to use a fixed eyepiece, search for something ranging from 20x-30x power. Choose an objective lens of around 60 mm in diameter to obtain a bright image. Go for an 85 mm objective lens in case of digiscoping. Also, purchase a nice tripod to mount the scope on. The tripod must have very few leg adjustments. All the above features are in best spotting scopes.
