Articles and News about Kowa Binoculars
Binoculars or binocular telescopes, are really two identical symmetrical telescopes mounted together. Because they point in the same direction, they allow the viewer to see a far greater distance than with the naked eye. A binocular has a big advantage over single telescopes as you can see through both eyes and they are easier to hold steadily with two hands.
The Optics
The objective lens diameter generally determines how much light is allowed while the magnification will display the ratio of the focal lengths. An example is 8 X 35 (eight times magnification and 35 mm objective diameter) or 7 X 50 (seven times magnification and 50 mm objective diameter). In these two examples, the first one has a higher magnification ( 8 over 7) but allows less light (35 mm is smaller than 50 mm) than the second one. If you are requiring binoculars for low light use, buy the biggest objective diameter.
Lens Construction and Coatings
Unfortunately, in any optical instrument used for images (e.g. a telescope, camera, microscope, etc.) light is often reflected and distributed into the view. This can reduce contrast. Reflection can be reduced by adding coating to the optics. Some of the newest techniques are phase-corrected prism and dielectric prism coatings.
Binoculars designed from the Porro prism design are generally brighter than a roof prism design but newer technologies are reducing the differences (the Porro prism binoculars still have the highest value at a lower price).
Choosing binoculars
Roof-prism models are generally lighter and smaller than Porro models, but you will usually pay more. If the binoculars are sealed and filled with nitrogen gas, they will not cloud with condensation.

Looking for 10x50 Binoculars? Then have a look below to see what we have on offer, stock changes daily
Other than M31 what galaxies are generally visible through 10x50 binoculars in the Northern Hemisphere?
I have located where Triangulum Galaxy (M33) should be but even on a very clear night is an extremely faint blur and I am not 100% sure I am not being deceived by a far distant star. Would any of the Virgo Cluster galaxies appear brighter?
One last thing - I am struggling to discern Jupiter's moons. With my binos stabilised the best I get is a slight bulge to one side of the disk which might be caused by an imperfection in focussing.
The key is to get to a very dark sky site. Then, m51, m81, m82, and maybe m33 should be visible, or at least detectable. You just might be able to detect m100 or m86 in the Virgo cluster. These objects should be as high in the sky as possible - so you're not looking through so much atmosphere. A planetarium program will tell you when they transit.
What i mean by detectable is that if you've found the right spot, and there's a bright patch where the galaxy should be, and you move your optics, the bright patch moves with the sky.
Focus is very important in seeing faint things. You can discover this by yourself. Get some faint star into sharp focus. Then defocus it. It should disappear.
Do you have a stable tripod?

Articles and News about 10x50 Binoculars
What to take with limited allowances for travel, in vehicles and/or light aircraft. The first thing you should do is invest in at soft bag. Your luggage will be squeezed into a limited space in your safari vehicle and a hard suitcases just will not do. Make sure the bag is plain, hardwearing with a sturdy zip.
We are often asked what binoculars to bring on safari we recommend the following: - a power x7 or higher. Look for any of the following: 7x42, 8x42, 10x42, 8x50, 10x50. It is the second number that is critical. Less than 30 and image quality is seriously compromised. Higher than 50 and you will have a hard job holding them steady. If you can afford Zeiss, Leica or Swarovski, all the better, but Canon, Nikon and Opticron do very good reasonably priced glasses.
[Recommendations for Binocular: - Magnification: 8 x 42 - Field of View: At least 330 ft at 1000 yards. - Exit pupil size: 5.25 mm or more Eye relief: 18 or more - Prism and Coating: BAK-4 prism and Fully Multi-Coated surfaces, Weight: Not more than 30.1 oz. Lbs]
MAKE A PLAN AND STICK TO IT! creating a list - like an architect planning a building, so must you plan the contents of your suitcase. Set aside the pieces you intend to bring and ensure that they are clean and ready to be packed
Jewellery - don't take what you don't want to lose, and leave behind the flashy pieces that could attract thieves. Keep makeup to a minimum to save space, and leave the perfume behind when scented lotions will work just as well. When it comes to toiletries - travel kits are always the answer. Having a travel kit perpetually stocked in a waterproof case will save in packing time before the trip and aggravation [and mess] after arrival.
A Kenyan I know is an expert packer - he will spend time packing using every space possible in you soft bag. He ensures everything is clean and ironed. Once folded he irons them flat - sometimes rolling but if they are ironed and folded correctly rolling is not always necessary.
Clothing To Pack for a Safari:
2 pairs khaki cotton pants (jeans are hot and uncomfortable)
2 pairs sturdy shorts
2 long sleeved light coloured shirts (for evenings help to keep the mosquitoes at bay).
1 light sweater or sweatshirt
1 lightweight, waterproof windbreaker
1 or 2 pair sturdy walking or hiking boots or running shoes [thick soles are essential as when walking in the bush there will many long sharp thorns]
3-5 short-sleeved shirts or T-shirts
5 changes underwear and socks
1 hat with a brim (baseball caps might cover your nose but not your ears and neck).
Please travel light. You should also bring a day pack to carry any essentials you might need whilst on safari. On safari most people wear shorts and a T-shirt during the day and put on long sleeved shirts and long pants in the evening for warmth as well as protection from mosquitoes.
Khaki, brown, olive and beige colours are best for and safaris and game walks.
White is not a suitable colour for these activities; they will get dirty with red/brown dust within minutes.Fleece or sweater and a windbreaker for game drives, because it is highly possible that you may go out on a hot day, but be faced with a chill evening on your return. Some areas have a steep temperature gradient, i.e. Very hot days and very cool nights.
Remember that layering your clothing will keep you warmer than relying on one thick item.About the Author:

Field Binoculars Q and A's
What is the value of Carl Schweitzer binoculars? 7X50, Field 7.1?
Binoculars have original case. Between the large lenses is code E.O.C. in triangle. They are in great shape.
This is difficult. A quick look at eBay shows nothing for this brand. Recent sales of 7x50 vary widely. Some items of historical or specialist interest have sold from $250 up to $850, with one pair selling for over $3500. The great bulk, however, sell for under $100.

Field Binoculars Articles and News
It's hard to track game if you can't see it. Therefore, one of the most important accessories for hunters is a good pair of binoculars.
While there are literally thousands of different models of binoculars on the market, not all are suitable for hunting. Most are not rugged enough for the woods, marsh or field. Many are not suitable for low-light conditions. Some are too powerful, and others not powerful enough.
Here are some factors you should consider when choosing hunting binoculars.
Binocular Construction:
Hunting is a rugged sport that puts demands on your equipment, including your binoculars.
Hunting binoculars should feature some sort of rubberized exterior armoring to protect them from being damaged if dropped or bumped against trees, brush, rocks and so on.
Because you'll likely be hunting in extreme weather conditions, you'll want a pair of binoculars that can withstand such conditions. They should be waterproof, and the lenses should be fog-proof. Another feature to consider are the lens caps. Binoculars with attached caps will protect the lenses, but not require you to fumble in your pockets looking for lens caps if it starts to rain or snow.
Roof prism binoculars are popular with hunters. Light enters the front (objective) lenses, and is then redirected through the roof prism to the rear (ocular) lenses. The roof prism design allows the binoculars to be more compact than binoculars that transmit the light directly from the objective lenses to the ocular lenses.
Binocular Lenses:
When it comes to lenses, bigger is indeed better. The larger the objective lens, the more light the lens transmits to your eyes. If you like to hunt at dawn or dusk, you'll want the largest objective lenses you can get. The objective lens size is the second number in the manufacturer's description of the binoculars. For example, 10x42 binoculars have 42 millimeter objective lenses. Objective lenses for hunting binoculars range from 40 millimeters to over 60 millimeters in diameter. Again, bigger is usually better.
When choosing hunting binoculars, look for phase corrected lenses. Phase correction is a coating on the lenses that increases the sharpness, contrast and color saturation. When you're trying to spot game that blends in with its surroundings, you need every edge you can get.
Another feature to look for in hunting binoculars is nitrogen-filled optics. The nitrogen inside the binoculars displaces oxygen, so that moisture cannot form inside the optics, fogging the interior lenses.
The rear (ocular) lenses are another thing to consider when choosing hunting binoculars. If you're like most people, your eyes aren't identical when it comes to focus. Therefore, you'll want to look for binoculars that allow each ocular lens to be adjustable for focus.
Consider, too, the amount of eye relief the binoculars feature. This is the distance from the lens to your eye at which you can still see the view. If you wear prescription glasses or sunglasses while hunting, you'll need some eye relief. Also, binoculars with good eye relief allow you to bring them up to your eyes quickly, without having to get your eyes perfectly aligned. 15 to 20 millimeters of eye relief is generally considered optimum.
Binocular Magnification:
The first number in the manufacturer's description of binoculars is the magnification. A pair of 8x42 binoculars magnifies the view by eight times.
For long-distance hunting, such as prairie dog hunting, a high magnification may be desirable. But for most types of wood/field/marsh hunting, too much magnification is undesirable. You'll be viewing too small a portion of the area you're scouting.
8x or 10x magnification is generally considered ideal for most hunting applications.
Many manufacturers offer zoom binoculars, which allow you to vary the magnification. In practice, though, zoom binoculars aren't always ideal for hunting. They tend to be more fragile and weigh more than fixed-magnification binoculars. Also, as mentioned previously, high magnifications restrict your view of an area.
The amount of area binoculars allow you to view is called the "field of view." The field of view (FOV) is referred to in degrees, or in feet at a specified distance. For example, 6 degrees of field of view is common. Expressed in feet, a pair of binoculars with 6 degrees field of view will allow you to see 314 feet of area at 1,000 yards.
Other things to consider when choosing hunting binoculars:
Weight is a consideration for any hunting equipment, including binoculars. 32 ounces may not sound like a lot of weight but, after a full day in the field, it will feel like it. Most binoculars made for hunting weigh around 20 ounces.
When selecting your binoculars, pay attention to the warranty the manufacturer offers. You're going to be exposing your binoculars to some pretty rough treatment, so you'll want the best warranty you can get. Many manufacturers offer warranties that last twenty years or more. Some even offer lifetime warrantees.
Properly cared for, a good pair of binoculars will serve you for decades. When you consider the cost of a single hunting trip, quality $300 to $500 binoculars are a great investment.

Roof Prism Binoculars Q and A's
Can you give me any information about Roof Prism Binoculars, like for example, how it is built and designed ?
Roof prisms are an alternative design to Porro prism pair binoculars. In both cases, multiple reflections serve to deliver an image that is neither upside down nor left-right reversed. A roof prism requires a longer optical path through a dielectric (the material of the prism) and more reflections, so, all things being equal in terms of material quality, produces a fainter, more chromatically aberrated image. The optics also require a greater precision. In general, roof prism optics are far more expensive to produce the same performance as a good ol' Porro prism pair set of binocs, and of course if you use the best materials for both, the roof prism will not perform as well for the same cost.
Another advantage of the Porro setup is the input polarization state of the light is preserved. The advantage of the roof prism is that the design is more compact and potentially lighter.
You can follow the links below to get a very cursory look at how these two designs work in binoculars. If you hunt for searches on just "roof prisms" and "porro prisms" you will probably find more info on how these specific optical elements are designed.

Roof Prism Binoculars Articles and News
The sport of hunting falls fully in the latter category and is purely done in pursuance of interest. However, hunting needs precise tactical gear to bring about the best results. The expressions 'duty gear' and 'tactical gear' may mean the same, or can have different connotations, based upon who is using it. Duty gear is the essential equipment that one needs to perform one's duties. Tactical gear is the extra sharp gear designed to facilitate that performance in difficult situations.
Tactical gear may not be everybody's duty gear because all types of explorers and adventurers need tactical gear to pursue their interests, which may not be part of their duty. For police and military, there is not much difference between duty gear and tactical gear, because, they approach difficult situations as part of their duty. For example, policemen would be climbing mountains as part of their duty while civilians may be doing the same as a hobby, but both of them would require more or less the same type of tactical gear.
Hunting is the killing of wild animals for sport and hunting gear is never anybody's duty gear. Though hunting of endangered species is restricted in some places, tactical gear for hunting has evolved without any restriction. A good pair of binoculars, carbon suit that can eliminate human scent, and a GPS unit that incorporates advanced features, are some of the right tactical gear that hunters can use to make sure that they take the game home.
Binoculars, which is a necessary tactical gear for many operations like climbing, sailing, and night patrolling, is necessary for hunting as well. Of the two types of binoculars available – namely roof prisms and porro prisms - roof prisms accommodate the more recent technology. It is more expensive than porro prism, but is much lighter and easier to handle, and gives better service as tactical gear. Binoculars are for distance vision, but a good pair of hunting binoculars should be able to focus close also. While buying binoculars, hunters should check whether it can focus in a range of up to 12' to 14'.
Another tactical gear for hunting is human scent elimination suit. Many hunting game can smell human presence and will run away from the hunter's vicinity if it detects the human smell. The carbon lined scent elimination suit can prevent the wearer's body odor from leaking out into the atmosphere for about 40 hours. The suit has to be activated before wearing. For getting the best results, hunters should avoid wearing this tactical gear when they start from home. They should not use it while driving and should don it only once they reach the woods so that they get the maximum benefit from its functional hours.
A GPS is also a necessary tactical gear for hunting. A GPS unit can do many things like display the hunter's exact position on the hunting ground, calculate distances and speeds, store locations that have been crossed during the travel, help the user to navigate back to the vehicle, or even track the position of the hunting dogs if they are used. There are many varieties of GPS units to choose from. Those, which have features like radio facilities, are waterproof, are camouflaged, or can give warning signals when necessary, do a very good job as tactical gear.
Duty Gear Store is your one-stop shop for quality tactical gear, Police Duty Gear such as Badge Holder, Tactical Boots, Gear Bags, Gun grips, Holsters, and under Armour boxer jocks. Please visit the site for more details of police duty gear - http://www.dutygearstore.com/
