Designed to be as light as possible with maximum ergonomic comfort, these Nikon Aculon binoculars aren’t giant, but they’ve been found highly useful for nighttime stargazing. If you’re just looking for a high-class set of ‘regular’ size binoculars, you’ll have a hard time going wrong with these. Recommended by amateur astronomy class teachers, the Aculon 7×50’s cost about a fourth of professional grade astronomy binoculars, but provide much of the same performance.
The little brother to the underwhelming 10x42 submitted in the full-size category, this 8x32 charmed the test team with its compactness and relatively better optics. Like on the full-size Fujifilm, the chassis of the mid-size KF feels flimsy, and the boxy style seems retro without the cool. On the upside, the testers liked the four-position eyecups and the overall balance of the open-bridge design. Very good image scores—including low-light brightness—elevated the KF’s ranking.
Since you're not looking at really far distance, I don't think you need anything more than 6x or 7x...this lower power will bring the subject in close while maintaining a wide field of view. If you need more power, I wouldn't go any higher than 8x. Also, depending on the objective lens diameter you go with, keeping the power to the 6-7x range you'll also benefit from a wide exit pupil and (generally) longer eye relief.
Whilst the size of the objective lens determines to a large degree how much light can enter the binoculars, it does not completely determine how much light enters your eyes, which is far more important. A measurement known as the Exit Pupil gives you the width of the column of light exiting the eye-piece and is calculated by dividing the Objective Lens size by the Magnification of the binoculars.
The Leica 8X42 Geovid is an all-around excellent range finding binocular that delivers outstanding performance when you need it. In addition to its stunning range of view and excellent optical clarity, the 8X42 offers unparalleled ballistics information at the push of a button thanks to the binoculars' patented advanced ballistics compensation technology which allows you to record and obtain proper rifle ranges. It is perfect for hunting, hiking, and other outdoor activities.
Tripod Adapters As mentioned before, binoculars with magnifications of 10x and higher are hard to hold steady, especially if they have large objectives. Large binoculars sometimes have a built-in tripod mount that makes it easy to mount them on a tripod. Sometimes a tripod adapter is required. Typically, full-sized binoculars have a plug that unscrews from the front of center hinge. The adapter screws into its place and mounts on most quick-release plates or tripods. Some tripod mounts are simply a small platform on which to lay the binocular and hold it in place with an adjustable strap.
Weighing at 34.7 ounces, it is not the lightest of the lot. You might feel a bit fatigued after carrying it for a longer time period. But it has long-range capabilities which outweigh this aspect. The range is estimated to be from 10 to around 2000 yards, which is much more than a mile. The binocular has a micro sd card slot which can be used to feed the ballistic information. Having a field of view of about 374 feet per 1000 yards, it is one of the biggest you will come across. The range and field of view go hand in hand to deliver you the view of a much larger area through the binocular, something which most of the rangefinder binoculars cannot offer. This will easily make you forget the weight of the device.
The magnification and objective of a binocular are always complimentary. The range of a rangefinder binocular also depends on these two aspects. You might have seen the binoculars being denoted by a set of numbers such as 7×20 or 10×42. What it denotes is the magnification and the diameter of the objective lens. For example, if the binocular is denoted by 7×20 it means that 7x is the magnification and 20 are the diameter of the objective lens. The magnification requirement depends on the purpose of your purchase. If you have bought it to take it to the movies, the ideal magnification would be anywhere from 3x to 5x. If the purpose something like sports, 7x would fair perfectly. But for hunting the best option would be 10x magnification. But one thing you have to keep in mind is that the field of view reduces with increase in magnification. The field of view of a 7x rangefinder binocular would be more than that of a binocular with 10x magnification. Also, it will be difficult to hold a rangefinder binocular which 10×42 for a long time as it will be heavy. The help of a tripod stand can be used in such cases.
If this japanese-made binocular looks European, that’s entirely intentional. It’s the first full-size bino from a new brand that hopes to marry European style and optical performance with retail prices achievable from the lower production costs of Asian partners. The Passion looks, feels, and performs like a higher-end European binocular. The machined aluminum eyecups are first-rate and the controls are tight and precise. The glass is excellent. The price is a bargain for an optic of this quality, especially considering the fully transferrable lifetime warranty.
Binoculars come in two basic designs based on the type of prism used in their optical construction — the traditional porr0-prism design and the more modern roof-prism design. Until relatively recently porro-prisms were by far the most common type of binocular on the market. However as the prices for high-quality roof-prism design has come down their popularity has increased.
The Leupold Shadow Gray 6x30 BX-1 Yosemite Binocular features a compact form-factor outfitted with traditional BAK4 Porro prisms and a fully multi-coated optical path to display more depth of field than similar roof prism designs. The resulting images transmitted by the Yosemite binocular have lifelike depth and are crisp and clear with high-contrast and accurate colors across the field of view.
I am shopping for a pair of good binoculars for my husband for Christmas. We attend all of the UGA games, so this pair would be used for viewing sporting events. Our daughter is in the marching band there, so we will also use them to follow her on the field. I have read about the image stabilization of the Canon produts, but I am not sure if we need it? Do you have a great pair that you would recommend for my gift? Also, my husband wear glasses
Compact binoculars are essentially scaled-down versions of full-size binoculars, with similar rubberized construction to protect against impacts, waterproof seals, a central focusing knob, twisting eyecups, and foldable hinges—yet they are about half the size and weight (around 10 ounces vs. 25 ounces or more). Because the lenses are narrower, the field of view (how wide an area you see while looking through them) is reduced compared with that of any full-size model. But, particularly if you have neck/shoulder pain or don’t mind sacrificing a little optical performance for the ease of packing them in a pocket or tote bag, they’re a solid choice for “light” birding, butterfly-watching, or botanizing. They’re also ideal for mountain biking or backpacking, when you may want to look at a couple things on the trip, but they’re not constantly in use.
This is a rather challenging topic when it comes to discussing binoculars. They are typically heavy products and keeping them steady might be an issue. The problem is, the larger the magnification, the more difficult it is to get a clear image, as even the smallest vibrations can manifest as a shaky, unusable image. A popular option is to mount them on a tripod. But if you’re on a boat, or in a car, the fact that they’re moving will counteract the tripod’s effect and you’ll still get a shaky image.
There is an adage that goes "the best pair of binoculars is the one you use." If yours aren't comfortable to hold, carry, or look through then you aren't going to use them. Things like rubberized coatings on the barrels, indentations for your hands and thumbs, an open bridge, comfortable interpupillary distance, padded straps, adjustable eyecups, weight, size, and eye relief can all affect how comfortable a pair will be. All of these measurements are very subjective and will differ between individuals. For instance, not everyone's eyes are set the same distance apart, so everyone will be most comfortable with a slightly different interpupillary distance. The amount of eye relief can be a big concern for someone with glasses and of little concern to others.
Another recent innovation is image-stabilized binoculars. These employ the same ingenious mechanisms found inside the best video cameras. Push a button and the shaky magnified view suddenly calms down, almost freezing in place. The result is that you can use higher magnifications, get away with slightly less aperture, and yet still see more than with conventional binoculars.
These Canon binoculars offer something different from the above options because of the image stabilization function. This means that they minimize any shake and are much easier to use by hand – you just push the image stabilization button and the shaky image steadies. This means that for casual stargazing and astronomy, they can be used without a tripod.
Birders tend to gravitate toward the 40mm range for their binoculars. Binoculars with 40mm, 42mm, or 44mm objectives serve as a good medium compromise between low-light capability and portability. Objectives smaller than 35mm will lead to a more portable package at the expense of light gathering, and a 50mm or larger objective will give you a very bright image along with, potentially, the aforementioned sore neck and shoulders.
Two other models also excelled in our brightness testing, though they didn't shine quite as brightly as our top scorers. The Vortex Viper HD 8x42, and the Leica 10x25 Ultravid BCR both provided bright images in our testing, even when conditions were overcast. We were surprised at how well the relatively small Leica performed in this regard. Clearly the company's high-end glass can make up for some lack of objective lens size.
High-performance features include: fully multi-coated optics and BAK-4 prisms, and custom adjustment with center and right diopter focus knobs. They have an extra-large field of view with crystal clarity from edge to edge; Ultra-smooth center focus that's easy to operate, allowing you to pinpoint your subject, Right diopter adjustment so you can fine-tune your viewing.
"I was introduced to these binoculars when taking a bird-watching class. I already had some inexpensive 'permanent focus' binos, and these Pentax binoculars were a revelation! Crisp depth of field for the sharpest images make these the choice for bird/animal watching. Easy and simple focusing system, with retractable eye cups for eyeglass wearers. Can't beat these binoculars for the price!"
Steadier - As long as they are well balanced a larger heavier pair of optics will resist moving better, so are often easier to hold steady, which can be a consideration if you are using a high magnifications. They are also far easier to use and more comfortable to hold than tiny compact binoculars, especially true if you are using thick gloves in winter.
Whilst these SuperGiant astronomy binoculars have smaller objective lenses (80mm) than the Tachyon binoculars from Zhumell, this does mean that they weigh in at just 4.4 pounds, meaning they are small and light enough to use in the field, but of course are best mounted to a tripod and they come with a built in tripod mount that takes any standard photographic tripod for longer periods of observation.
Whilst the field of view on astronomy binoculars is not as important as it is for people using their binoculars to view unpredictable, fast moving objects, like birds, it is still fairly important. Field of view is basically the width of the scene that is in view when you look through your binoculars, for a full explanation see field of view in my optics glossary. A wide field of view will make it easier to scan the night sky and find objects when looking through the binoculars.
Image stabilized binoculars are those with a compensating mechanism which adjusts many times per second, usually in conjunction with electronics, to eliminate most movements in the image you view. While the compensating mechanism may vary between brand names, the concept of stabilizing the view remains constant and amazes those who've not previously experienced it. Naturally, the compensating mechanism, electronics and batteries all add weight to the binocular. The benefits, however, outweigh the costs to the extent that these binoculars are rapidly gaining in popularity. It's up to you to decide whether these types of optics qualify as "best binoculars for astronomy." They're quite nice, but they're not essential to enjoying the celestial sites.
The Fusion ranges out just a tad less than its competitors, but nevertheless, it’s still a full 1,760 yards – a complete one mile. Bushnell is straight-up with its specs as they disclose that its soft-target ranging is only 500 yards. While that might seem on the low side for a high-powered and expensive optic, we do appreciate the truth of its abilities. However, 500 yards is still pretty, doggone far!
These are special coatings added to the outer lens surfaces, typically of high-end premium binocular models, designed to protect the more the delicate anti-reflective coatings from abrasion and damage during use and cleaning. They also usually repel water, dirt and grease, making the binoculars easier to use in the rain, and much easier to clean than binoculars without such coatings.
You may also find more numbers below the magnification-x-aperture rating. These give the field of view, which is how wide a scene you'll see. It's expressed in feet at a distance of 1,000 yards, or, more commonly these days, in degrees. (The conversion is simple: 1° is 52 feet at 1,000 yards.) Binoculars' fields of view vary from about 10° (the size of the Big Dipper's bowl, or the size of your fist held at arm's length) for wide-angle models, to a mere 2° (the width of your thumb at arm's length) for high-power models. Most of the time, though, the field of view is about 5° to 8° wide: about as much sky as is covered by a golf ball or squash ball held at arm's length.
