Celestron 71198 Cometron 7x50 Porro Prism Binoculars, Black

Product Information

However, because of the complications of viewing through two eye-pieces at once, in most cases, “ Zoom Binoculars” are not really recommended. The magnification range is often termed as the power of the binocular. As most of us have heard, with great power comes greater responsibility, with higher power ranges, there are certain consequences. For example, with increased magnification power, the field of view gets dimmer, and vice versa, and so the image produced is darker as compared to the normal light field. The multi-coated optics will help the binoculars render a crisp, color correct image that is also bright and easy to see. New from Gael Force, these focus-free, waterproof BaK4 prism binoculars are buoyant and include an illuminated compass with distance calculator. They are identical to the Konus Tornado and Talamex Lankhorst Taselaar Deluxe binoculars, except for a different hand grip and colour, but are quite a bit cheaper.

As you approach another vessel it will of course get larger, but a fishing boat may take some time before its direction can be identified by the naked eye. Not only does this aspect give a clear idea of the range of field of view of a binocular, but it also determines the quality of the image that will be produced at the other end. The in-depth detail of any image captured from any distance in a binocular depends upon the close focus distance. Scouting the surroundings is possible with ease, due to the large field of view granted by the ration between the lens size and the magnification power of the model. Secondly, the most valuable accessory in terms of using binoculars for astronomical purposes is a tripod stand. We cannot stress the importance of a tripod stand in the case of binoculars as it solves so many smaller, seemingly unrelated problems.Weight: The weight of the binoculars is an important consideration, especially if you’ll be carrying them around for extended periods of time. A lighter weight can be more comfortable to use, but heavier binoculars may offer better image stability. Recent developments in lens coatings have improved them to the point where up to around 90% of the light gathered by the objective lens can be delivered to the ocular lens. This makes them particularly good for reduced visibility and night vision. Compass binoculars Visit 'HAWKE LIFE' : A lifestyle hub for the outdoor enthusiastFeaturing tips, techniques & advice from passionate sporting men and women Field of view: The field of view is the amount of scenery that you can see through the binoculars. This can be important for activities like birdwatching or sports events where you want to be able to follow the action across a wide area. Some Best-Selling 7×50 Binoculars Models 1. Steiner Marine 7×50 Binoculars: The relatively large diameter lenses, combined with a somewhat small magnification power should fit in plenty of scenery. The precise figure is expressed either in linear dimensions, meaning feet at a standard distance of 1000 yards, or through the actual angle of view, which hovers around 7 degrees for the best marine binoculars.

BaK-4 Prism Glass Glass– Good quality optical glass is used on the prisms, for a better and brighter view. Very Wide View– At 393 feet wide at 1000 yards away, these Fujinon Polaris binoculars have a viewing angle of 7.5° which ranks them up there with the very best 7x50 binoculars. Each tester had their favourite, often influenced by the shape and size of the binoculars: a bit like shoe size. You need to try them: people’s inter-pupillary distance does vary. The metal frame makes these binoculars sturdy and capable of handling some wear and tear without a glitch. The generous 7mm width of the binocular's image disk more than compensates for the minor cut-off of the best image area. (Image credit: Jeremy Lips & Dave Brody)Because the planets, stars, comets, and even the moon are so far away from us, many people logically assume that you need a very high magnification binocular for astronomy and indeed giant high powered binoculars like a 15x70 or even a 25x100 are important for and commonly used for astronomy. Weather Resistant– Whilst not completely sealed, they are described as weatherproof. This should keep out light rain and dust. However, should you also require your 7x50 binoculars for marine use or often go out in the worst weather conditions, you may be better off with a fully o-ring sealed and thus fully waterproof instrument. Rather than a focus wheel, these binoculars are fixed focus / focus free binoculars and thus once calibrated to your vision using each of the eye-pieces, you no longer have to alter the focus for any objects from medium range right to infinity and thus are particularly ideal for stargazing and boating. For example, if you plan on using your binoculars for outdoor activities like hiking and birdwatching, you may want to prioritize a lightweight and portable design. On the other hand, if you plan on using them for stargazing, you might prioritize a larger objective lens diameter for better light-gathering ability. B. Other specifications to take into account In addition to a wide exit pupil diameter, the brightness level of its image is supplemented by light absorbing coating, which prevents glare and also adds color correction.

The base model of the Steiner marine range is available with or without an analogue compass. The construction utilises a two-way valve technology that makes maintenance possible at any time, even after many years of use. An integrated compass is rather common, and most often display true north directly on the binoculars’ main view. However, this might add additional weight and cost to provide you with data you could get from your actual compass. The other advantage of a 7x50 is that the combination of a very wide view and bright optics also makes a great low light general use, wildlife and particular bird watching binocular.Eg 18mm, the distance between your eye and the eyepiece for comfortable focus. This is a critical performance factor, especially important for those wearing spectacles: the longer the distance, the better. Wide View– with a viewing angle of 7.1° or to put it another way a view that is 372 feet wide at 1000 yards away, these 7x50 Sightron SII binoculars make it easier for you to scan the night sky, locate objects and study them without having to move the view about. First of all, let’s have a closer look at magnification. The Nikon aculon a211 binoculars have a magnification of 7x and an objective lens size of 50 millimeters. This is great because it gives you enough power to view objects far while still retaining clarity. And as far as the field of view goes, the magnification on these binoculars is definitely impressive. Optics Do you know what is most important in astronomy? The objective lens of binoculars is without a doubt. This is the lens that collects the light from an astronomical object and projects it onto your eyes. And what do you get with the Celestron cometron 7×50 binoculars? You get high-quality optics coupled with a nitrogen-fused coating for longer life; this means you can use them for years without any problems at all. Price
