What is this part of a binocular called?
http://img265.imageshack.us/my.php?image=nikondw4.jpg
Its the part in the middle of all the arrows that says nikon on it. I just got these same binoculars and I couldnt really seem to move it all that easy. It has 2 numbers and little dots all along the right side of the wheel.
Does anyone know what this is and how to use it. I thought that it was used to focus it but I dont know.
It looks like the focus knob to me. It should turn fairly easily.

What type of binoculars and camera do I need for Alaska wildlife ?
I'm taking a 2 month trip to Alaska and want to be able to view wildlife and take some pictures . I want to stay under a $2,000 price range and I want equipment that is easy to use because I am not a professional.
Thanks for your help .
Spend most of your money on the camera, not the binoculars. You can view the wildlife through the telephoto lens on your camera. You can buy a decent pair of binoculars, pocket size or larger, from Bushnell or other companies at any sporting goods store or Target-type store for a relatively cheap price. The reason I recommend putting your money into the camera is that the better camera and lenses you have, the better results you will take home. For sure you want a telephoto lens. You can get a camera with a zoom lens that goes from a standard view to a mid-range telephoto view, or you can buy one with interchangeable lenses. If you do that, in addition to buying the regular 50 or 55mm lens or a macro-zoom for snapshots and scenery buy a large telephoto (500mm+ if you can afford it) so that you can get good close-ups of moose, bears and birds. Secondary would be a macro lens if you are into flower pictures. For clear pictures with a telephoto lens you will need a tripod. Some nice lightweight backpacking tripods are out there, and they'll fit in a suitcase or duffle. There is too much lens shake with a big magnification lens to make a clear picture just holding it in your hand. The places where you would most likely use the telephoto and tripod would be scenery shots, swans on a lake, moose feeding in ponds and bears in Denali National Park. For the quick shots of a fox by the road, you'd have to turn off your car to avoid vibration and rest the lens on your car window or on the shoulder of a steady friend.
Buy a good quality camera, such as a the Canon, as mentioned by another answerer. Your photos will only be as good as the quality of your lenses and camera. Since this is the trip of a lifetime, you don't want to go cheap on an off brand.
Buy several spare batteries and a charger and spare memory cards if you aren't uploading to the web. Nothing worse than a battery failure just as a herd of caribou cross the road.
You will need to protect your equipment. This doesn't necessarily mean buying an official camera case. They can be good, but are also targets for thieves and sometimes hard to carry. I've seen many cameras riding around in padded Tupperware boxes or other containers inside backpacks, fanny packs, etc. If you don't like carrying a lot of weight around, then pay attention to size when you buy the camera. Large telephotos take up a lot of room, so if you don't want to deal with that, then compromise with a zoom lens.
Keep your camera with you at all times, to avoid theft and to take advantage of the many many photo opportunities that you won't want to miss, including taking pictures from the airplane. If you sit on the right side of the plane as you face the cockpit, you'll see some great views as you fly north to Anchorage. If you sit on the left from Anchorage to Fairbanks, you'll see Mt. McKinley if the weather is clear. For whale photos, take an ocean trip out of Sitka or Seward or Homer.
Whatever camera you buy, become thoroughly familiar with it before you leave home. Learn how to take pictures of sunsets, fireworks, people, snow, close-ups, items far away, moving items, etc. Learn what every button and setting does.
Have a great trip! Alaska is a wonderful place and you will get some great pictures. Don't be shy about asking locals about places to take photos or to see wildlife. Not everyone will know the answer, but many will and will be happy to give you the inside story or to tell you about upcoming events.

Your application is the most important factor in choosing a microscope. What you need to see and what you want to do with that image will determine what kind of microscope you need. Microscopes typically come in two types: compound or stereo microscope.
The most common is the compound microscope. It is the one most people visualize when they think about microscopes. A microscope with one eyepiece is called a monocular microscope; with two eyepieces it is called a binocular microscope, or it might have an additional camera tube and is called a trinocular microscope. The compound microscope has a number of objectives (the lens closest to the object being viewed) of varying magnification mounted in a rotatable nosepiece. It uses a light source beneath the stage to illuminate slides. These microscopes are generally used to view very small objects such as cells or bacterium. Magnification of compound microscope scopes range from 40X up to 1000X. Actual magnification can be figured by multiplying the power of the eyepiece by the power of the objective lens.
The other type of microscope is called a stereo microscope or dissecting microscope. It uses two eyepieces and two paired objectives. Stereo microscopes come in models that have full zooming capability and models that just have only two magnification settings. Stereo microscopes are particularly useful for biologists performing dissections, technicians building or repairing circuit boards, paleontologists cleaning and examining fossils or any one who needs to work with their hands on small objects. You can find stereo microscopes that have a built in light source from above, below, or none at all. Magnification is usually much less than that of a compound microscope, but is figured in the same way by multiplying the power of the eyepiece by the power of the objective lens.

What kind of bird is this?
This morning I woke to this bird outside my window going ""chaaay, chi eeee" its makes two chirps and has a very loud voice, like a mockingbird's. I tried to get some photos of it, my camera isn't that great though. also it didn't turn around for me so all I got is photos of its back. it has a white furry chest.

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/

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.

Matt is a Binocular fanatic that has many binoculars available for sale at auction prices at his website Compact Binoculars.
Does anybody know how to make a binocular/periscope?I don't want a regular plain periscope.10 pts to best answ
I have to create an optical device that would allow you to look at an object about 1 m above u and from about 10 cm of distance away or any distance away. I have to use mirrors, lnses, and prisms. I don't want to make a regular periscope because that's uncreative. We're being marked on origanilty as well. I sorta wanna make a periscope/ binoculars. Something that works lie a periscope but you put it up to your eyes and you can get different magnifications. Please help! Any suggestions guys? I would be so grateful if you have a website.
i get the wheel part, but not exactly the shaft part. what do u mean?
For the different magnifications you could install a wheel type device. Only the upper portion of the wheel is exposes so you can turn the wheel to various positions simply by turning the wheel along the exposed portion.
Inside the wheel actually has several lenses attached to it, as the wheel turns the next lens aligns itself so that the image is being magnified with the lens in alignment. The wheel should have definite stops that can be felt as one turns the wheel. The stops must be at the point of alignment for the lens.
Therefore, by looking through the device, one can turn the wheel on top to rotate to the next lens and view an object at different magnifications.
The wheel could be installed on to a shaft, like a flywheel is on the motor of a car. The shaft is supported by brackets mounted to the housing, and the shaft hold the lenses in a plastic like wheel device itself. As the wheel turns the shaft turns to align the lens, as described above.The thing to do is to set it up so the wheel you turn only turns the shaft, this way a smaller wheel can be used to turn this shaft. It could be a gear to gear relationship between the wheel and the shaft.

Binoculars have many different uses. Binoculars are used for hobbies, work, military, and even law enforcement purposes. Almost everyone has seen a pair of binoculars whether on television or in person. When thinking about hobbies that involves binoculars bird watching is probably the first thing that comes to mind. Watching a bird soar through the air using a pair of binoculars can be a thrilling experience. This gives you a first hand look at nature at work. Scientists have used this method a long time now to study bird behaviors not only birds but other animal behaviors as well. From a distance scientists have a chance to observe animals without disturbing their natural behavior.
Before buying a bird watcher binoculars you should research the best binoculars for your budget. While not all binoculars are expensive with a decent budget you can consider extra features that might make the experience even more pleasurable. All binoculars are classified by a power level or magnification specification. The higher the number the larger the distant image will appear. However the higher the magnification the harder it will be to hold the binoculars steady. Anyone new to binoculars is better off with a magnification lower than 10x. Tripods are a cheap fix but also make the binoculars less portable. A more expensive solution is image-stabilizing binoculars. These types of binoculars are built to keep the image steady but also make the binoculars heavier.
Weatherproofing and armoring are a good idea which protect the binoculars making them last longer. Weatherproofing falls into three categories none, showerproof, waterproof, and nitrogen purged. Nitrogen purged waterproofing is the best choice for bird watchers. Nitrogen purging always keeps out dust and sand. Armoring is good for all binoculars regardless of use. Armoring provides shock resistance. No matter how careful we are some times we get a little clumsy. Dropping your binoculars is a scary thought with armoring it isn't nearly as bad. Both are a very good idea if you happen to purchase a very expensive pair of binoculars. It would be a shame to drop and destroy your binoculars on your first bird watching trip.
Binoculars with cameras can sometimes be found at discount prices. The camera will take pictures of everything you see through the binoculars. Some even allow the possibility of videos. With cameras you could print out the images at home or send them to a fellow bird watcher. Extra memory is a good ideas if you plan on saving a lot of pictures or videos. Well by now you should know all there is to know about binoculars and bird watchers. One final rule: Have fun!

Have you ever used those binoculars with a built-in digital camera?
I am looking to buy some binoculars with a built-in digital camera. Are they any good? Anyone out there who have used them wanna tell us what you think of them? thanx
Seen em at the local Sharper Image/Brookstone and they dont seem to be much better than a camera with a decent zoom lens... Not sure how much the bino-camera costs, but you may want to check out a good camera instead...

Roof vs porro prism binoculars
Astronomic binoculars are optical instruments used in stargazing or day and night sky viewing. It allows people to see far objects besides those seen by the naked eye. Choosing good binoculars for astronomic purposes entails some considerations. A good pair of astronomical binoculars is more effective as a telescope.
Binoculars are small telescopes mechanically linked together or mounted side by side, allowing distant viewing. It is handy, durable, light and easy to use. Astronomical binoculars can help you see up to 40% of a more detailed observation as compared to using only one eye with a telescope. In order to get high quality astronomy binoculars, one should follow certain considerations for good results:
Magnification
Choosing the magnification level also reflects the way it is intended for usage. With the handheld method, the setup time is zero. It has no accessories so as to drain the pocketbook. This means that one should keep magnification below 12x in order to maintain the steadiness of your binoculars. However, an objective size combination allows you to view hundreds of stars and galaxies, only through the use of a 7x to 12x binocular.
Hence, you can also determine the binoculars exit pupil (a virtual aperture in an optical system) which can match your eyes. It is done by dividing the size of the objective lens via its magnifying power.
A human eye has 2mm of exit pupils during the daylight, making it a type of high magnification. The exit pupil needs to be more than 5mm in low light so as to make it more usable. Since all binoculars have limits, one should consider the amount of distance to be achieved when focusing or the so-called eye relief. Binoculars having a 9mm eye relief can produce uncomfortable viewing.
A tripod can also help you to effectively handle magnifications over 15-20x. Astronomic binoculars have 15x to 30x and can result to a more detailed stargazing. This is while a 25x100mm can be very effective for a dark and clear night viewing.
Most giant binoculars possess a limit, especially for fixed magnification. This is although more model types now offer interchangeable eyepieces.
Sizes
Lens Size - Aperture (opening or a hole through which light is admitted) is referred to as the size of the objective lens. It is a light gathering source that plays a key role in suiting binoculars applications. More apertures mean better and brighter resolved images. The size and bulk can also increase proportionately. Binoculars are very portable, having a size that is less than 30mm. 5x25 or 5x30 models can also fit into the pockets easily. Low magnifications are necessary for this size range in order to keep a bright image.
Binoculars that have 40mm are considered as mid-range sized. It is used by most people for multiple applications. A 50-60mm lens size is far heavier that requires support. However, this is well suited for astronomy.
Mounts
Big binoculars need to have big mounts. The weight of the binocular can be compared with its maximum load capacity on a tripod. A tripod that has the capacity of at least 12 lb. and 15 lb. or more is best for an 80mm binocular.
Prism Type
Z shaped porro prisms are best suited for astronomy binoculars. Porro prisms have no mirrored surfaces and are less expensive. It can even inherent image sharpness which is intended for large hands.
The prism allows the body to be seen onto a far shorter view. This is because it folds the light path. It can also flip images and reflects the light path 3 times.
Focus Type
Astronomy binoculars use both CF (center focus) and IF (individual eyepiece focus). Center focus is versatile and easy to use, especially in refocusing other applications. If the focusing system is a more practical type, it is then easier to seal against moisture and dust.
Quality and Price
Most giant binoculars are made in China. Some Chinese optics is made with high optical standards. Popular brands include the following:
• Celestrons
• Oberweck
