Humans are naturally born full of curiosity and thirst for knowledge; that is why questions are asked about the existence of many things within the Earth and even outside the Milky Way galaxy and of the existing celestial bodies in the entire universe Universe.
Queries about the things that exist millions of light-years away from us couldn’t be answered by just observing the night sky with our unaided eyes. Although some are visible, it would be a hazy and blurry view. It would always be best to do astronomical observation with the help of telescopes or a high-powered binocular.
Each of the two optical instruments has its strengths and weaknesses. First, to maximize your tool’s total potential viewing capacity, you must know what activity you are specifically conducting. Different kinds of telescopes are a prevalent tool among beginners and amateur astronomers, as they are excellent to use when observing distant objects, especially celestial objects, and watching birds, wild animals, seas, etc.
However, binocular is also another excellent optical instrument that professionals or beginners much prefer.
Here are the following advantages of binocular vision.
Binocular vision is the ability to focus on a visual image with two eyes. Humans and animals like owls, apes, and other predators have binocular vision that makes their prey, like small birds, deer, rabbits, and fish cannot escape because they only have monocular vision. There are significant advantages among animals that can see an image with two eyes. Just like these creatures, binoculars also have this type of vision. Let us find out what benefits we can get when we use this optical device.
Increased Depth Perception
Try covering your one eye and look around. You will see the difficulty of seeing a broad view of what’s in your surroundings. With both eyes or binocular vision in front and near each other results in a more precise sight and highly improved perception of depth of things. This is because you can better distinguish how near or far the subject is from you.
So, this applies to the use of a binocular when doing your stargazing or moon watching.
Allows 3D Vision
The binocular vision of the eyes allows you to focus on looking at a particular object. Since the eyes are positioned just inches apart from each other, you can see two different images. In comparison, the brain translates the two images into one, allowing people to watch in 3D.
Binocular allows you to enjoy a spectacular 3D view of the distant viewing subjects as it amplifies them, making you feel as if you could touch and reach them. No wonder bird watchers and love to use this over telescopes.
One best thing about using binocular is the option to either use both eyepieces or just one. In the case of a damaged eyepiece, there is still the chance to use the tool, just like the human eyes, if one gets blinded.
This is best explained by Leonardo Da Vinci, who said that if there is a vertical column closer to a person than the image or subject of focus, it might block a portion of the image from one eye, but the other eye can still see that part of the image. This is a significant advantage compared to using telescopes.
Much Easier to Use Than Telescopes
While some telescopes, like Dobsonian reflectors, don’t require a complicated setup, others, particularly GO-TO scopes, have intricate mountings that must be aligned and in level with the North Celestial Pole before they can accurately track objects.
This is a steep learning curve in and of itself. And that’s before you even look up through the eyepiece to see the stars. On the other hand, a pair of binoculars has only one or two adjustments, which you can adjust in under three seconds. Furthermore, binoculars don’t need to be polar-aligned; point them at the sky and begin looking around.
Much Cheaper Than Telescopes
Some binoculars are costly; however, most binoculars suitable for bird viewing will also be suitable for astronomy, especially if you have no immediate desire to track down “faint fuzzies” (faint extended clusters) or, attempting to split close double stars.
While most medium-sized telescopes can split numerous close double stars and show faint fuzzies, getting the most out of a telescope demands more than a basic understanding of the sky. It also requires several eyepieces and filters, which can be more expensive than the telescope itself. However, all seasoned telescope users will concur that knowing what they’re looking at contributes to a significant portion of the fun of seeing the stars via a telescope.
Guide to Choosing Your Binoculars
Considering all these advantages, binocular can take you to the next astronomical adventure or bring much clarity to your outdoor experiences. Other people consider this instrument as an extension of their bodies. While you may be excited to get one for you or your kids, there are a few things that must be considered when buying a binocular.
Know Your Budget
Deciding on which brand or type of binocular is best for you always entails your capacity to purchase it and have it in your hands. So, it is best to set a price range that suits your budget best.
Know Your Primary Purpose in Buying
Binoculars come in different magnifications to cater to different needs. Higher magnification means more complexity and gives a better view of distant objects.
You Can Pick the Best Ones at Either 8x or 10x
Generally, 10x binoculars are better at distance birding, but it has a narrower field of view, a slightly darker image in low light, and a more noticeable handshake. Meanwhile, an 8x gives you a smaller image that’s wider, brighter, and easier for finding and following birds.
Check the Eye Relief
This is an essential thing to note, especially for eyeglass wearers. Most binoculars have retractable and extendable eyecups to accommodate both eyeglass wearers and not. If you wear glasses, look for durable, multi-adjustable eyecups.
When using a binocular, adjust the eyecups to their minimum position and ensure enough eye relief—you shouldn’t see black rings around the image.
