What Are Big Binoculars And How Can They Be Made Easier To Use?

Sphere: Related Content
The intended use of binoculars may vary. Capabilities depend on the size of the binoculars and the power they have. Specifications and strength of binoculars define its power and its use. The power of binoculars is determined by two parameters: magnification and the width of the aperture lenses or the effect of light. If binoculars are described as [7 x 50], the first letter represents magnification, while the second letter represents the diameter of the objective lenses. In this case the object viewed will appear 7 times closer than if it was viewed without binoculars. The second number 50 represents the propensity of the binoculars to gather light. The higher the second number, the brighter the viewed object will be. One of the uses of binoculars with high second numbers is stargazing, but there is a problem that must be resolved with initial use of these binoculars. The weight of binoculars of size [7 x 50] and above makes it impossible to use by simply holding it up to your eyes and freely viewing objects. Installation of a binocular mount will hold these binoculars in place, providing support.

Binoculars are defined as big binoculars when their specification indicates the second number is 50 or more. Binoculars [7 x 50] are considered big binoculars. These binoculars are physically heavy and their use can be affected because they are cumbersome. Some uses of big binoculars include surveillance, bird watching, hunting, and star gazing. Binocular mounts are used to change the way big binoculars are placed for use. With this renewed change, big binoculars assume their purpose and they are available for use.

A binocular mount is designed to provide support appropriate for large binoculars and small telescopes. The mount requires modification as it is being installed. The mount must be shaped to provide singular support to hold the equipment. It is imperative to find a suitable location for mounting the binoculars. After completing all the necessary preparations, assembly of the mount is completed. This support facilitates big binoculars, so they can function with ease.

Binoculars that are very large may not have outstanding features. Maybe they are just big and bulky without much purpose. When purchasing binoculars, it is important to investigate the product so you will know what you are getting.

New optical technology has been introduced bringing everything 80x closer. These zoom compact binoculars are the smallest on the market and they include all the necessary features with high performance magnification and clarity. They produce sharp, high-contrast images. These binoculars allow you to view objects at 20x magnification and then to zoom to 80x with maximum focusing capability, while retaining sight of the object you are viewing.

New ideas on selecting binoculars caution that power ought not to be the chief goal when choosing binoculars. Consideration of light gathering, field of view, and ease of use are also important. Binoculars with too much magnification can weigh too much, and this equipment may be too uncomfortable to use for very long at a time. These binoculars require a mount and use will have some limitation. Bigger is not always better. Consideration of the intended use of binoculars will be helpful when ordering equipment.

Shopping For Binoculars For Astronomy and What to Look For

Sphere: Related Content
Looking at astronomical objects with your binoculars is a big difference from seeing those objects with your own eyes. You can observe astronomical details that would normally not be visible with the naked eye. Buying binoculars is a more affordable and easier alternative to viewing the sky with a telescope.

In many ways, binoculars are better than telescopes. Starting to look at astronomy with binoculars is a much cheaper way to get started with sky gazing than using a telescope. Telescopes are heavier and hard to use, but binoculars are light and easy to carry. Binoculars don't have to be put together like a telescope does, allowing you to see something quickly. Binoculars also have a much wider field of view than telescopes which allows you to find objects faster, telescopes are very hard to use for beginners because they have such a small field of view. Even if you already have a telescope, binoculars are a great way to get an idea of where something is so that you can then get the telescope and view it. Another advantage is that everyday observation like bird and plane watching is easier with binoculars.

When using Binoculars to observe astronomy, there are a few things that can help. Checking the internet for current astronomy events about moons, and comets can tell you when to look for a certain object. A sky atlas is a big map of the night time sky that can tell you what you are looking at. I suggest using a tripod for astronomy because it can be hard to see with constant shaking. A nice lawn chair or blanket also helps.

Using Binoculars allows you to see better and farther than with the naked eye. Binoculars are a lot cheaper than telescopes and in some ways they are better. First off, they are a lot lighter, and easy to carry around. They are also very easy to use compared to telescopes. Wide star clusters are best viewed with binoculars because of the wide field of view. Aiming at an object with a telescope is a lot harder than using binoculars.

Pick a set of binoculars that are good for what you are using them for. Some binoculars are better for certain things than others. The best magnification for astronomy is between 7x and 12x. Anything above 12x will make it hard to steady. If you want more magnification, than a tripod will let you get into the 15x - 30x range, but it still is not as nice as a telescope.

Marine Binoculars

Sphere: Related Content
If you like fishing or any other marine activities that might include using a boat then you should get yourself a pair of marine binoculars. These are extremely useful for spotting things that might be in your path, or which are there as a safety reminder e.g. buoys and markers. These binoculars are a terrific aid to your night time vision and to the distance that you can see, marine binoculars are waterproof and an indispensable aid to water activities.

For those who are new to marine binoculars the 7x found in the binoculars reviewed below for example, refers to magnification, thus things are magnified seven times and this is felt to be the maximum amount of magnification that can be properly handled when out at sea. So 7x50 referred to below is the magnifying factor times the size of the lens, which is generally 50mm. So 7x50 is the most generally accepted size of binoculars designed for marine use – this is because that particular combination gives a steady image along with the maximum of transmitted light that can be accepted by the human eye.

Nikon have a number of different models of marine binoculars, one of the more popular sets seems to be the 7x50 CF Waterproof Ocean Pro Binoculars which come complete with their own case. The Nikon 7x50 is constructed from durable lightweight polycarbonate and has a number of useful features, its 50mm objective lens allows for maximum light gathering and the large central focus knob makes it easy keep your focus. The field view is thirty eight feet at a hundred yards and the fold down rubber eye caps are designed to protect the eyes from bumps in rough waters - these binoculars are both waterproof and fog proof.

The Steiner 7x50 skipper marine binoculars with compass is more expensive than the Nikon 7x50 but has a number of extra features. These binoculars come with highly crafted optics for greater brightness and enhanced contrast; cat optics provide the brightest possible images when light is low and enhanced contrast in rough weather and bright sunlight. The high quality optics are designed to protect the eyes from harmful UV radiation and the Steiner Sports-Auto-Focus is designed to give the wearer maximum comfort. Steiner 7x50 skipper marine binoculars body is made from shock absorbent makralon fiber reinforced polycarbonate with slip-proof rubber armor. These binoculars come complete with carry case and lens straps and are ideal for boating activities.

When you buy marine binoculars there is often a choice between waterproof and those that are non-waterproofed; waterproof binoculars are more expensive but are specially designed for wet conditions. Some binoculars will have waterproof written on them while others may say nitrogen filled, which means the same thing.

Spot Game and Fish With Hunting Binoculars

Sphere: Related Content
Sitting in the woods waiting for game to pass by can be a tedious wait, but you can gain an advantage by using hunting binoculars while sitting in your tree stand. You will able to spot the game from a distance and verify a projected path and end the question of which way it is traveling.

However, there are numerous considerations in choosing the best hunting binoculars for you, and the geographical locations in which you hunt. Magnification, light gathering and ability to work in the weather environment of your hunting grounds will determine a good pair of hunting binoculars.

For general use binoculars with a size rating of 8x30 would work well, that is they have a magnification factor of eight and light gathering ability of 30. However, if you plan to get out in the wilds before dawn, perhaps hunting binoculars with a 8x40 or 7x50 rating would be better as they would have more light gathering capability.

Check For Non-Fogging Lenses

Hermetically sealed hunting binoculars filed with nitrogen are generally used for extreme weather conditions where freezing is a distinct possibility. They should also have the ability to be collimated as they may need adjusting as time goes by.

Each side of hunting binoculars are simple a telescope attached to another identical telescope. Their optical array is different than traditional telescopes to make them smaller and easier to handle. Both sides should give a bright, clear and identical image if viewed individually. Working together they give the appearance of a three-dimensional image, nearly identical to the original.

Magnesium fluoride coated lenses also reduce reflection to allow for brighter and more accurate renditions of the subject. A good pair of hunting binoculars will also have reduced reflective quality to reduce the amount of glare visible to animals. The outside of the unit should also be considered as to its visibility to game animals. Camouflage coverings are popular on hunting binoculars.

Another concern of hunters is noise and hunting binoculars usually have no exposed metal which would click together and possibly give away a hunter's position. Putting it all together you might consider a 12x50 power set of hunting binoculars with coated lenses, ability to be calibrated and collimated as they get used. Flat green exterior with rubberized coating, nitrogen-filled and waterproof for up to one meter depth, providing years of reliable service and weighing just under two pounds.

Fishing Binoculars Help Imaging On Water

Due to light refraction through water, seeing undistorted images is a problem but a good pair of fishing binoculars can make the images more colorful, more realistic and without the distortion. Ultraviolet coating on the lenses of fishing binoculars also reduces the glare from the sun as it hits the water.

If you are on the water looking for signs of where the big fish are located, such as jumping Marlin or Blue Fish, a good pair of fishing binoculars can be a big help. The distortion-free vision offered on many models gives a better idea of the distance and most fishing binoculars come with extreme depth of field capabilities allowing for sharp images anywhere from 20 yards to infinity.

Fishing binoculars, since used on or near the water, are generally waterproof and the depth of their resistance to water infiltration will often determine the price. It is also important to remember to protect your fishing binoculars from the continued exposure to salt water if they are used on ocean cruises.

Seek Out Features You Need

If you are planning to spend a lot of time on a boat then fishing binoculars with coated lenses is necessary. These will reduce the amount of glare from the sun and make your images more defined. Additionally, with the glare almost completely gone, images will not be hidden by the reflected light.

Whether you are using the fishing binoculars to actually look for fish movement on the water or for trying to spot the shoreline if you get lost, be sure the magnification is strong enough to meet your needs. Depending on the size of the water way you be on will determine the strength of the fishing binoculars you will need.

Center focus fishing binoculars will enable one-handed operation easier and along with the prism being mounted on the roof of the binoculars making them more compact, they will be easier to carry, store and use. A rough waterproof coating is also desirable to make for more sure handling if they, or your hands, do get wet so they will not slip overboard.

The angle of view is determined by the lens size and depending on your needs, you may want a wider view lens. Similar to the lens on a camera, fishing binoculars also come with a variety of lenses. They are available from numerous manufacturers in many styles and magnifications. Resultantly, costs can range from about $40 to several thousands of dollars.

How to Pick a Good Pair of Binoculars

Sphere: Related Content
Binoculars aka field glasses are like two telescopes pointed at the same area. It is easy to perceive depth because it has two lenses and not just one, like a monocular.

The binoculars have been around since about the 17th century after telescopes have been invented. People use to mount two telescopes side by side and looked through them with both eyes.

Between the 1850-1890s, a prism type of binocular was invented that allowed greater depth perception by allowing the eye pieces to be spaced wider apart. These binoculars allow greater magnification.

The most affordable binoculars are porro prisms that allow for brighter images and are precise instruments. These binoculars are wider and sometimes need to be re-aligned.

An expensive kind of prism binocular is the roof prism binocular. This binocular is smaller and narrower but loses some brightness. The good think about them is that they usually never have to be re-alligned. They are also much lighter. Optical coating fixes this problem. That is why many roof prism binoculars are coated.

Optical Coating is a great feature that helps make a brighter image by reducing the amount of light that is reflected. Reflected light inside the binoculars makes the image hazy.

General Binoculars are focused by moving a round wheel that focuses both telescopes at once. More sophisticated binoculars use independent focus which means that each side of the binocular needs to be adjusted individually.

Some binoculars have image stabilization technology which dampen sudden movement. It can usually be turned on or off by the user. This means that very high powered binoculars can be hand held when normally they couldn't. The image quality is not always as good for stabilized binoculars, and they are usually more expensive.

Coin-operated binoculars are very popular in many tourist attractions. They allow a more detailed view. These are always mounted on a pedestal and are usually high powered.

Military Binoculars are usually hand held and at a magnification of 5x or 7x. Military binoculars are more rugged and sturdy than regular binoculars and they also use independent focusing because it is more sturdy than central focusing. Most military binoculars also have special features that help it work when wet or to block out laser beams. Sea binoculars are meant to be easier on the eyes because of the sea rocking back and forth.

Astronomical Binoculars allow people to view certain elements of the sky from far away. There are many moons and planets that can be viewed with binoculars. Pluto, Eris and Uranus can all be seen easier with the use of binoculars. Some users use lower magnification binoculars so they can have a larger field of view than if they used a higher magnification.

How Binoculars Work

Sphere: Related Content
If you understand how telescopes work, then you understand how binoculars work. Binoculars are, after all, nothing more than two telescopes attached to each other.

Binoculars are essentially a series of mirrors and prisms made of glass that take incoming light and provide the viewer with a magnified image. Each half of the binocular has three major parts.

The lenses at the front of the binoculars, the largest lenses, are called the Objective Lenses. The Objective Lens is where all the light comes into the binoculars. The Objective Lens focuses the light coming into the binoculars, and projects the image it receives as an upside-down image into the binoculars. In this way, the Objective Lens is a refracting lens. The larger the Objective Lens, the brighter the final image will be since it can take in more light. The trade off, however, is in convenience, as a larger Objective Lens will result in larger and heavier binoculars. Of course, higher quality lenses can be brighter than cheaper Objective Lenses of any size. Indeed, to ensure that the Objective Lens projects the sharpest image possible, it is important to use a high quality lens. With lower quality lenses, not all the light will be refracted at the same angle, causing the final image to be distorted in shape and color.

The image is turned the right way up by the second major part, the prism. In the common Porro design, the image is turned the right way up by two prisms set at right angles to each other. This is what accounts for the traditional binocular shape. For more money, you can get binoculars with a roof prism setting that allows for a more streamlined design. No matter what layout the prisms use, the final result is always the same. The prisms then project the corrected image down the binoculars towards the last major component.

The third major part of the binoculars is the eyepiece lenses. These lenses fulfill the binoculars' main purpose of magnifying images. The eyepiece lenses then project the magnified, right way up image to the viewer's eyes. It is important to consider this last step, from the eyepiece lenses to the viewer's eyes. Every pair of binoculars has a different eye relief, or optimum distance between the viewer's eyes and the eyepiece lenses. In particular, if you wear glasses, you should look for binoculars that have a long eye relief. So, now that you know how binoculars work, get out there and try some!

What's So Different About Waterproof Zoom Binoculars?

Not all binoculars are equal. Whether you are a professional paparazzi, in the military, a marine biologist or an amateur astronomer, you will get a lot more accomplished with waterproof zoom binoculars than just any old pair of binoculars. You need to quickly locate your target or focus on your surroundings and then move off to another location to check out. You can’t waste time endlessly twiddling with the focus function of your binoculars. You need to invest in a pair of waterproof zoom binoculars.

Thar She Blows!

Let's say you work for a humpback whale conservation organization. You're out on the open ocean and need to not only count the humpback whales in your area, but identify them. Humpback whales have markings on their tails and flukes that are as individual to them as fingerprints are to us. Humpbacks will only stick their flukes and tails out of the murky water momentarily, so you must identify them as soon as you spot them. Otherwise, you've missed your chance.

This is one occasion where the superiority of waterproof zoom binoculars shines over standard waterproof binoculars, or even image stabilization waterproof binoculars. You do absolutely have to have waterproof binoculars is you are out in the water for any length of time. Although salt water is far more corrosive than freshwater, the pollution and hard metals in a lot of freshwater can still cause damage to your delicate lenses.



The demand for waterproof zoom binoculars has grown and so has the variety of makes, sizes and even colors of the binoculars to meet this demand. Don’t just go with the first pair of waterproof zoom binoculars you come across. Ideally, you want to get a pair with a free trial period or some sort of return policy, should the binoculars prove to be too uncomfortable to use.

There are very compact and lightweight waterproof zoom binoculars on the market, but if you are going to be using them a lot, then you do need to consider getting a sturdier model. If cost is a real issue, then look into getting a waterproof monocular, instead. However, larger binoculars tend to be less expensive than the tiny palm-sized compact models. This is because they are often not in such a demand as the smaller models. Still, you can expect to pay about $100 (US) for a pair of quality waterproof zoom binoculars.

How to Buy The Right Binoculars For You

Sphere: Related Content

Binoculars are wonderful pieces of equipment that can enhance many of our daily activities including, birding, action sports, hunting, and even astronomy. Essentially binoculars take a distant image, enlarge it through the use of lenses for viewing, all while remaining small and light enough to be mobile.

The actual makeup of most binoculars is fairly straightforward and simple. You have the lenses at the end of the barrel called the objective lens that gathers the light from the distant image and focuses it on the lens closest to your eyes for viewing. Binoculars are really two small telescopes put side by side so that you can view the desired image with both eyes instead of just one. This imparts some measure of depth of field, much more so than with a single scope.

When selecting a pair of binoculars you will immediately find that two numbers are used to describe their capability. These numbers are often expressed as "6 X 30" or something similar. Let's break the code so you will know what these numbers mean.

The first number refers to the magnification power of the binoculars, or in other words how many times the image is magnified. So if the number is 6, that means that the image that you view through the lens is magnified 6 times it's normal siZe.

The second number has to do with the size of the objective lens at the end of the binoculars.It's good to know this number because the larger the diameter of the objective lens, usually the more light will be let in for viewing the distant image.

Now, let's put this information in use in the real world. You may think that it's best to just get the highest magnification that you can get for binoculars, but this is not true. At some point, hand holding the binoculars will affect the clarity of a highly magnified image and the resulting shake will render the magnification benefits useless. Generally speaking, anything above ten times magnification should be mounted on a tripod instead of handheld. So if you are planning to use binoculars for activities that do not allow you to be able to bring along a sturdy tripod, you probably want to stay with a pair of binoculars with 4 -7 times magnification.

As far as light gathering properties are concerned, if you plan on using your binoculars in any kind of low light situation whether indoors, or at times of day when there is low available light outdoors, then you need to have a large objective lens, usually 30 or above, to make as much use of available light as possible.

Finally, consider the weight of the binoculars before buying them. If weight will be a consideration for activities such as hiking, then perhaps plastic lenses will be best that are specially coated to produce a high quality, sharp image. These can be more costly than glass lenses, but they are considerably lighter. Glass lenses usually make for much better optics and clearer images at a lower overall cost, but they can also be more fragile.

Generally speaking, more expensive pairs of binoculars have more atention paid to fit and finish and will stand up to more vigorous use, but if you only plan to occasionally use your binoculars, then a less expensive pair will no doubt work fine. Also, remember that after the purchase you should be sure to protect your investment with a suitable binoculars case.

The Do's And Don't When Buying Binoculars For Astronomy

Sphere: Related Content

Using Astronomy Binoculars allows you to see things in the sky that you would normally not be able to see with your own eyes. There are many small details that cannot be seen with the naked eye. Buying Binoculars is a lot cheaper and a lot easier to use than to use a telescope.

Some people think that binoculars are actually better than Telescopes. If you are new to star gazing, binoculars are a much more cost effective way to get started in the hobby than a telescope. Telescopes are bigger and harder to set up, but Binoculars are small and can be used hand held. Binoculars don't have to be assembled like telescopes do, allowing a faster view time for objects that move quickly. Telescopes have a much smaller field of view than binoculars, meaning it is harder to find what you are looking for with telescopes than with binoculars. If you own a telescope already, buying binoculars might not be a bad idea because it can come in handy trying to find something with binoculars before using your telescope. General observation with binoculars is much easier because of the bigger field of view.

If you are going to star gaze with binoculars, make sure you used the various resources available. The web has a calender that shows you when and where to look to see certain comets and moons. There are also sky atlas' that show you all the different parts of the night time sky. If you are using high powered Binoculars, a tripod helps you keep your view steady and allows for a better quality image. Make sure to pack chairs or blankets for long nights.

Binoculars allow you to see much more detail than when using just your plain eye. You can get a good pair of binoculars for much less than a good telescope. For one, they are a lot smaller, and easier to handle. Binoculars are also easier to use than telescopes. When looking at wide groups of stars, binoculars are much easier because of the greater field of view.

Chose a pair of binoculars that fit your needs. Most binoculars are made for a particular purpose. Astronomy Binoculars should be around 7x to 12x. Magnification above 12x is too hard to keep stable. If you require a higher magnification, then a tripod can help you get into a higher range.

Nightvision Binoculars Can Come In Handy In Many Situations

Sphere: Related Content


You never know when you may need to see at nighttime. You may find yourself hunting at night, you may be playing paintball with your friends in the dark woods, you may be looking for intruders on your property that have alerted your dogs, or you may just be bird watching at night. Whatever your reasons, you'll love a pair of nightvision binoculars. You'll be amazed at how they magnify the light even when it seems there isn't any to be magnified. The military used to be the only ones with their hands on this sort of technology. They still use them to this day for nighttime military operations, even going so far as to put nightvision binocular scopes on their rifles for night sniping missions. However, just like compact binoculars moved from only spies using them to the general public, nightvision binoculars are also now available for anyone who wants to buy them.

Magazines And Army Surplus Stores

There are many magazines that highlight the newest technology to move from military issue to the general public. You can often order items such as nightvision binoculars from these magazines. Army surplus stores are also great ways to get military issue gear that has moved to the civilian population. You should check both of these avenues to see if they have the nightvision binoculars you're looking for. These are the perfect way to get your hands on the perfect pair of binoculars for whatever you may be using them for.

The Internet

Nowadays, there's not much you can't find on the internet. You can definitely find nightvision binoculars online and you can probably find them at a price you can afford. The great thing about buying online is that you can often look at consumer reviews to see how people may have liked the product or may have found it less than satisfactory. However, make sure you take any reviews with a grain of salt. Anyone can have a bad experience but if you find many bad reviews for one product, you can be sure that those nightvision binoculars aren't worth your time or money.

There are various types of nightvision binoculars. There are cheap ones that can be used for any situation and then there are the more high powered versions that are more in tune with what the military uses. Depending on what you need them for and how much you have to spend, there is likely to be a pair of binoculars to suit you and your needs.

Everything You Need To Know About Binoculars

Sphere: Related Content
Binoculars are the world’s most used type of optical instrument. They have many different uses, and choosing the right pair for a particular application is crucial. There are binoculars for astronomy, bird watching, marine, military, hunting, opera, compact, digital, and more. As you can see there are quite a few different types of binoculars that you can choose, from but one of the most popular are the digital binoculars.

Terminology

There is some binoculars terminology that you are going to need to be aware of if you want to make sure that you choose the right pair for you and your needs. The field of view is very important, and this is the amount of territory that you see when you are look through the binocular.

Two things determine field of view and these are magnification and eyepiece design. The exit pupil in a binocular is the actual width of the beam of light that leaves the eyepieces and is measured in millimeters. To see an exit pupil all you need to do is hold the binocular at arms length and you will see a circle of light in each eyepiece. This circle is the exit pupil, and to calculate the exact size of the exit pupil, you simply divide the first binocular number into the second binocular number.

It is important to check out the exit pupil when you are trying to decide which pair to buy because a large exit pupil is easier to keep centered on the eye and this is a major advantage. For instance when it is difficult to hold the binocular steady such as on the deck of a moving boat.

The twilight factor will also play a major role in deciding which pair is going to be right for you. This is a mathematical formula that predicts the amount of detail that can be seen in low light. Twilight factor is the square root of magnification multiplied by the objective.

How To Choose

It can definitely be tricky to decide on a pair of binoculars for yourself, especially if you have never done it before. There are so many different options staring back at you from the shelves, but as long as you keep these helpful tips in mind and remember to choose the right pair, depending on the specific application you are going to be using them for, you will be alright.

This information will help get you well on your way to finding a pair of binoculars that will be perfect and last you a lifetime.
