6 factors to consider when choosing a telescope

A pair of the best binoculars is a necessary investment for any keen or budding nature observer. Not only that, but some tiny telescopes can also be used for stargazing, and they’re valuable in any situation where you want to bring the far one a little closer, like shows and sporting events.

Start shopping around and you’ll quickly find a wide variety of prices and styles on the market, which can make things confusing, especially for the uninitiated. Finding the best telescope for your particular needs is crucial. Of course, how powerful they are in terms of magnification is a question, but there are other factors to consider as well. So let’s take a look at 6 factors to consider when choosing a telescope.

6 factors to consider when choosing a telescope

1. Enlarge

The magnification of binoculars is numbers written in x’s. So if the binoculars say 10x, they’ve magnified the subject by a factor of ten. For example, a bird 1,000 meters away looks to the naked eye as if it were 100 meters away. The best magnification is usually between 7 and 12 times.

2. Objective lens diameter

The objective is the opposite of the eyepiece. The lens size is crucial because it determines the amount of light entering the binoculars. So in a bad light situation, if you have an objective lens with a larger diameter, you’ll get a better image. Lenses rank after X in millimeters. A ratio of 5 to magnification is ideal. Between 8×25 and 8×40 lenses, the latter has a larger diameter and produces brighter and better images.

3. Lens quality and coating

Lens coating is important because it reduces the amount of reflected light and allows the maximum amount of light to enter. At the same time, the quality of the lens ensures that the image is aberration-free and has better contrast. The best lenses work better in low-light conditions because they can transmit more light. They also ensure that the color does not fade or distort. People who wear glasses should look for high vision points.

4. Visual field/exit pupil

FoW refers to the diameter of the area seen through the glasses, expressed in degrees. The larger the field, the larger the area you can see. The exit pupil, meanwhile, is the image on the eyepiece for the pupil to see. Exit pupil is obtained by dividing the lens diameter by magnification. The 7mm pupil gives the enlarged eye maximum light and is ideal for use in dusk and dark conditions.

5. Weight and eye strain

You should consider the weight of a telescope before buying it. Consider whether using binoculars for long periods of time can make you tired. Again, use binoculars to see if it’s causing damage to your eyes. While regular binoculars are hard to use for more than a few minutes at a time, high-end binoculars hardly cause any eye strain and can be used for extended periods of time if needed.

6. Waterproof

Since binoculars are essentially outdoor products, it’s important to have a degree of water resistance — often referred to as “WP.” The regular model can stay in limited water for a few minutes, while the high-end model won’t suffer damage even if submerged for several hours.


A good pair of binoculars can help you catch more big games and spot more birds. Binoculars allow you to locate more animals and determine the size of the animal you are targeting at a distance beyond your normal vision. But choosing binoculars that suit your hunting and adventure style can be tricky. Binoculars are also one of the most complicated hunting equipment you can buy, and you should know these six factors when choosing the right pair for you.

Depending on your interests and hobbies, long-distance binoculars are a very convenient and portable option for a variety of outdoor activities, including bird-watching and star-gazing. The best long-range binoculars are a reliable hand-held option that can be easily carried in a backpack or hung around your neck while camping, hiking, etc. Even better, most long-range binoculars are made of rugged materials that can withstand time, high falls, and all manner of harsh weather conditions.

Apexel 10X42 Fixed Focus and Free Focus Binoculars

Apexel RB10X42A binocular Conventional focusing telescopes need to continuously adjust the focus to capture a clear vision of the target when watching fast-moving targets, and they are simply helpless when facing high-speed moving targets. And this fixed-focus telescope (APL-10X42A) has a precise fixed-focus optical path calibration, providing you with operations without focusing and keeping a clear view at all times. Allows you to observe high-speed moving objects naturally and calmly so that you will not miss any wonderful moments.

(1) High-Quality Image

For a 10×42, the image brightness is super impressive.
For almost all users, but especially for birders and wildlife observers, an excellent and true-to-life image is a critical feature as it ensures you are not only able to marvel at the beauty of nature in all her glory but also remember that tiny differences in things like plumage colorations can make the difference when trying to positively identify one sub-species from another.

(2) Wide Field of View
As most wildlife observers and especially birders will know that having a wide field of view is an extremely important feature as it enables you to more easily find and then follow your subjects, this is especially true of the small faster-moving ones at closer range. At 3.4ft wide at 1,000 yards, these have an extremely wide view that ranks up there with the very widest 10×42 binoculars currently on the market and which is why I would certainly describe them as being wide-angle binoculars.

Using incredible FMC multilayer optical coatings and sophisticated BAK4 optical prisms, these high-spec optical components are well combined. Indeed they literally have no major weaknesses. This makes them a very versatile instrument that will not only stand out in most types of wildlife or birding situations but in many other areas as well and certainly up there with the best binoculars I have ever used at this price level.
