  Promotion telescope to teach you how to measure function

Published 2011/1/24 17:57:00 - Ceramic Ball

    First contacts the telescope's friends always have many questions, for promotion telescope, how short time closed out the selected telescope function?

   Now promotion telescope can view how far do introduction:


   Ordinary telescope effective distance in 60-1000 meters.

  1. The telescope unhealthily and people's eyesight relevant:

Such as eye chart of letters "E" in 5 meters yuan place test, people with good eyesight can see the bottom line, shortsighted people could only see above a few lines of big "E".

If the was in 50 metres, with 10 times the telescope, equivalent to closing the 10 times, (and five metres distance observation do). People with good eyesight can still see the bottom is same, myopic or only see above a few lines of big "E", the bottom or can't see clearly. Shortsighted people will say this telescope see 50 meters, even the most these letters are not being able to see clearly, and people with good eyesight will say this telescope is very good, with 50 metres was the most these letters can see, you can say this telescope can see only 50 meters?

  2. A telescope unhealthily and object related to the size of the:

For example 1000 metres an ant, you use the telescope, equivalent to ten times the ants close to 100 metres, you must still can not see, you can say this telescope see 1000 meters? If 1,000 metres a person, with 10 times the telescope, then the equivalent man to pull 100 metres, then affirmation is to see.

Eye chart of letters "E" in 5 meters far place test, people with good eyesight to see the bottom is same, shortsighted people could only see the above a few done great "E". Why? Just because the bottom lines letters "E" is too small!

Through telescopes can see 380,000 kilometers of ringed mountain, they did not see the moon is quite near to us the earth satellites, is because they are too small, that is the reason why.

   3. Telescope unhealthily and air quality related:

For example with the same with binoculars, observe 1000 meters outside goal, in sunny day can see a clear goal, and after rain, cloudy day without sun and air a car tail gas, dust and circumstances, could see clearly.

One step closer, if the fog, in the air has a large amount of suspended particles, reducing visibility and so probably 50 meters all could not see, this is the fog weather why blockade highways reasons.

 Binocular Ratings - How to Pick the Best Binoculars

Published 2011/1/21 9:24:00 - Ceramic Ball

For being such a simple device, there sure are a lot of choices when it comes to binoculars. There have been some recent technological advances in binoculars that include electronic image stabilization and digital image capturing. That means those simple binoculars do more than just magnify, they can now keep the image steady and even take a digital picture of what you are spotting in your binoculars. But for the most part the main job of binoculars is simply to magnify. So how should you choose and what should you consider when reading binocular comparisons or ratings of binoculars?

The first feature you should look at is the binoculars' power measurements. The power is listed by a pair of number such as 10x25, pronounced "ten-by-twenty five". The first number is the amount of magnification. In this case the image would be magnified by a power of 10, or in other words would appear 10 times closer than without the binoculars. The second number listed is the size of the lens in millimeters. In this case the lens is 25 mm in diameter. So the larger the first number, the closer your subject will appear to be. But what about the second number? The lens size determines how much light enters the binoculars. The more light, the sharper and brighter the image will be. So at first glance it would seem you would want binoculars with the highest power measurements as possible. But you must consider that larger lenses mean larger and heavier binoculars, and in most cases, more expensive too. So it is best to first consider what you plan to use your new binoculars for.

If you just want to observe birds at your back yard feeder, then a small birding binocular or spotting binoculars that are light and simple to use would be the best choice. If you plan to mount your binoculars on a tripod and use them for astronomy study, you should choose a larger Celestron binocular. Your decision will most likely involve compromising size and weight for power and image quality. You should pick the highest powered binocular that you are comfortable holding and carrying. Obviously you wouldn't want to haul large-lensed high powered astronomy binocular to a concert. You should choose compact binoculars that are easy to carry and conceal.

Aside from a binoculars' power measurement, additional features to consider are weatherproofing and the electronic capabilities mentioned earlier such as image stabilization and image capturing. If you plan to use your binoculars for camping, fishing, hunting, hiking, boating or any other outdoor activity, you should probably choose a weatherproof or waterproof binocular. Waterproof binoculars have a rubber coated body which keeps out moisture and protects the optics and internal parts from corrosion. Stabilizing binoculars and camera binoculars are fun and those features are great, but those same electronic features add size and weight to the binoculars. Are those features worth the added size and cost? That is a decision you will have to make when you compare binoculars.

Once you have decided where you will be using your binoculars and what you will mainly be using your binoculars to observe, you can then make a smart decision about the size and power you need. And with most purchases, you should first know your budget and then match your needs to your budget. Perhaps you should choose used binoculars? Sometimes buying used binoculars is the smartest choice. Other times buying new is the only option. Take your time and make a smart buying decision and enjoy your binoculars.

 Binoculars For Boating

Published 2011/1/17 23:56:00 - Ceramic Ball

If you've ever gone on a dolphin or whale watching excursion, you know it's rare to see the animals up close. Boats are supposed to keep a safe distance from wildlife to avoid disturbing them, and sometimes the animals are just frightened away by the sound of a boat's engine, or excited people yelling about seeing a whale or dolphin in the water.

You don't want the excursion to be a waste of time or money, especially since those trips can be expensive. The best way to ensure you get to see what you went out there to see is to take some waterproof binoculars with you.

Any binoculars will work, of course, but out on the ocean, even in a boat, nothing stays completely dry. Waves splash against the boat, the motion of the boat kicks up spray, and if a curious whale or dolphin does approach the boat, you may get sprayed or splashed by them. If you're going to spend money on binoculars, it's best to get a waterproof model to protect your investment.

Pentax binoculars has several waterproof binoculars to choose from, so you can find what best suits your needs, and your budget. You can also choose between full size and compact binoculars. Compact are easier to travel with, but full size can also offer longer range views, depending on the model. A little bit of research will help you make the right decision about which binoculars to buy.

Waterproof binoculars are the first choice to take on any boating trip, but you may also consider trying image stabilizing binoculars. Even if the boat is stopped on the water, the motion of the waves can make it difficult to focus on any wildlife you may have the opportunity to see. Trying to do so can also increase the possibility of becoming seasick. Image stabilizing binoculars keep the image steady, even when you're moving, so you can keep the object in your field of view, and avoid seasickness.

Perhaps your interest is less in watching marine wildlife, and more in catching it. Whether you're fishing on a lake, or going after big game while deep sea fishing, binoculars can help you find game and keep your bearing while on the water. If you're in a small boat without navigation equipment, binoculars allow you to keep land in your sight so you don't get lost. While fishing, one thing to look for is a group of birds flying and diving over one location. This is an indicator of a school of fish near the surface. Binoculars will help you keep your eye on where the fish are.

When looking for a good set of binoculars to take when you go fishing, one high quality option is Tasco binoculars. They offer waterproof models at very affordable prices, without sacrificing any quality. A well-known name for more than 50 years, you can be sure that any model you choose will provide clear, sharp images. They even make a model with a built-in compass to help you find your way out on the water.

Whatever your boating purpose, there is no shortage of information to help you find a great pair of binoculars.

 Three Newbie Mistakes When Buying Binoculars For Bird Watching

Published 2011/1/12 22:10:00 - Ceramic Ball

There are three newbie mistakes often made by novice birders when choosing binoculars. You can learn from the mistakes of others and choose the best binoculars for birdwatching the first time. You'll have more fun with your new hobby and save money at the same time.

Mistake Number One - buying the most powerful binoculars you can afford. There are two problems with very powerful binoculars. First, they're usually pretty large. Remember those old "Victory at Sea" films with the giant binoculars mounted on the railings of ships? Don't forget, you're going to be carrying these around all day. More than that, very powerful binoculars are hard to use. It's difficult to hold them still without jiggling and the field of view is very narrow. That makes it hard to find the bird you're observing, especially if it's flying or even hopping around on the ground. The best binoculars for bird watching will be around eight to ten power.

Mistake Number Two - buying binoculars that are not waterproof. You say you'll never go birding in the rain? That may be true, but even water vapor from humidity in the air can be a problem. If your binoculars get any amount of moisture inside them they can fog up inside when that moisture condenses due to a change in temperature just like your mirror gets fogged up when you take a hot shower. Even if they dry out later, that day of birding was spoiled. Good, waterproof binoculars are filled with nitrogen to keep out moisture and even these can be found in a relatively inexpensive pair.

Mistake Number Three - believing the most expensive binoculars are the best. While there is a relationship between price and quality, the average bird watching enthusiast doesn't need to spend a huge amount of money on binoculars. A fifteen dollar pair will not have anywhere near the optical quality of a $100 pair and it will show in the sharpness of the image, especially around the edges. But the difference between a $100 pair and a $500 pair will be much less noticeable. As binoculars get into the upper price ranges, the quality in general still might get better, but in much smaller, even imperceptible increments. It's the old idea of diminishing returns. The good news is you don't have to spend several hundred dollars for good birding binoculars.

Avoid these three mistakes when choosing your binoculars for birdwatching and you'll do just fine. Look for a pair that is waterproof and around eight to ten power. You can find a great pair of birding binoculars in the one to three hundred dollar range. If your budget won't let you go over fifty dollars or so, don't worry. You can still have a lot of fun and perhaps upgrade in the future.

 Binoculars Tips You Need to Know Before Purchase

Published 2011/1/11 18:30:00 - Ceramic Ball

Before you purchase a set of binoculars, it is important to fully understand their purpose, any special requirements or features you will need and have a price range in mind. Example: if you are an avid day hiker or back-packers in the outdoors you might think about compact, lightweight binoculars that are waterproof and shockproof. If you are purchasing your optics for sheep hunting you would want rugged, high power magnification, large objective high quality lenses for long distance viewing with critical eye relief (less straining on your eyes as you view). 

My experience has proven to me that when buying binoculars, all things being equal, you get what you pay for. If you are buying binoculars for your grandkids there are plenty of brands offering inexpensive, attractive and quite functional optics perfect for the beginner. However, if you are buying for yourself it is my recommendation to do some homework, look around and compare different brands, features and price ranges.

Then while making your decision on the right set of binoculars strongly consider the fact that this purchase is an investment that you will have for your lifetime. This is not the time to go economy and shave the budget. Believe me, a great set of binoculars are more money but very well worth it.

Now, let's discuss how to define what a good set of binoculars is and what features you should consider:

Warranty: this is a good place to start. A limited lifetime warranty is very important and something you want. If you narrow your search down to two pairs of binoculars sometimes the warranty can be the tie breaker.

Quality of Lenses: understand the type of lenses, materials used in the lenses and what benefits the lenses offer. Most lenses are made out of glass, crystal, plastic or high-tech composites and have some type of coatings offering various types of advantages. Better quality binoculars will have a higher level of clarity and resolution providing the greatest advantage over the inexpensive binoculars.

Waterproof: a good set of binoculars will be waterproof which is always a good idea since most are used outdoors where the elements can turn nasty. To have a nice set of binoculars ruined because they were not waterproof would be a disappointing event. Waterproof binoculars are usually filled with nitrogen which helps them to stay moisture free. Waterproofing is actually done with the construction of the binocular and if it is fully waterproof it will be printed on the binocular. Most of the waterproof binoculars are also available with individual eye focusing system.

Shockproof: having the benefit of shockproof binoculars is a good idea. We do not intent to be rough on our optics but events happened in or out of our control that could permanently damage binoculars. I dropped my favorite set of binoculars many years ago and they were permanently distorted. Nothing I could do but throw them away as I mourned. 

Rubber Armor: this is not a must but it sure is nice to have exterior rubber armor on your binoculars. It provides some shock resistance, helps tremendously with your grip and reduces the tendency of sliding while lying on table tops or similar.

Objective Lenses: generally, the larger the objective (the size of the front lenses) the more field of view you will have and the more light that will be collected in low light conditions such as dawn and dusk. If you have not experienced this it is very neat. It can be almost dark out and look through your binoculars with large objective lenses and you can mysteriously see like an owl.

Eye Relief: Eye relief is the distance from the eyepiece to the point where you can see the whole picture. Small compact binoculars have more challenges with eye relief than most others. People who wear glasses often have trouble using binoculars, because their glasses hold the eyepiece too far away from their eyes.  People wearing contact lenses or people who do not need prescription glasses should not experience difficult eye relief issues.

People who need glasses but do not have astigmatism can look through binoculars without their glasses, adjusting for their nearsightedness or farsightedness merely by adjusting the focusing device. Generally, in this situation you take your glasses off before raising the binoculars to your eyes.

Weight: hunting or hiking all day with a large heavy set of binoculars can get annoying and not to ignore the fact about chaffing the back of your neck from the carrying strap. Weight should certainly be considered when selecting the right pair of binoculars.

Carrying Case: you want to protect your investment in between uses. A good hard shell protective carrying case is recommended.

Purchasing a good set of binoculars is an investment you will enjoy for a lifetime. Do you homework, consider all your options, make your investment and then enjoy!

 Sailing Skipper Guide - How to Pick a Perfect Pair of Marine Binoculars

Published 2011/1/9 18:26:00 - Ceramic Ball

If you are anything like me, nothing quite beats the usefulness of a great pair of high quality marine binoculars. They are one chart navigation tool that every sailing skipper should carry aboard for safer navigation by day or night. Use this simple guide to get the best bang for your hard earned dollar.

Select binoculars based on quality, comfort, clarity, and ease of adjustment. Good binoculars allow you to see vessels through haze, rain, or low light conditions. From far away, you can identify that buoy you're looking for or the friendly twinkle of lights that signal you've made your expected landfall.

Check the Field of View (FOV)

When you look through a pair of binoculars, a circle surrounds the object being viewed. The diameter of that circle at a distance of 1,000 yards is called the field of view, or FOV. A larger FOV helps keep objects inside the circle, even when your boat rolls or pitches in waves and swells. Purchase binoculars with a specified FOV between 350 and 450 feet at 1,000 yards.

Choose the Right Power for Sailing

The most common marine binocular powers are 7 × 50 and 7 × 35. The first number shows the amount of magnification of a viewed object. You'll need magnification of 6 or 7; anything higher causes objects to jump out of the FOV.

The second number is the diameter of the larger lens, or objective lens. This indicates the instruments ability to gather light at twilight or nighttime and in haze or fog. Larger is better. Look for an objective lens diameter of 35 to 50 millimeters.

Are All Rubber Coated Binoculars Waterproof?
Rubber coating provides the user with a better grip and protects against damage. Waterproof binoculars come charged with nitrogen to prevent intrusion into the prism or lens housing. Read the specifications and avoid binoculars bearing the much less protective "water-resistant" claim. You want waterproof, not just water-resistant, binoculars, and you'll be glad you spent a few dollars more after spray or a squall douses them.

*Note -- Eyeglass wearers should choose rubber-coated binoculars with the fold-down eye-cups. These help improve focus and provide comfort when bracing the binoculars against glasses.

How to Focus Binoculars to Perfection
Binoculars come with center focus or individual focus eyepieces. Center focus makes adjustment easier and readjusting unnecessary as your viewing range changes. Many fine professional marine binoculars, however, come with individual focus lenses. They just take a bit longer to adjust and need readjustment at different ranges.

Take the time to learn the adjustment process for both types of instruments. Now you can select the perfect pair that will give you satisfaction for years to come.

Individual-Focus Eyepiece Binoculars

1. Focus the left eyepiece. Close your right eye or cover the right objective lens. Focus the left eyepiece on an object at least 1 mile away. Mark the scale setting between the body and the focus ring.

2. Focus the right eyepiece. Close your left eye or cover the left objective lens. Focus the right eyepiece on a distant object at a range of at least 1 mile. Mark the scale setting between the body and focus ring.

3. Reset the focus when ranges change. With individual focus settings, you'll need to make incremental adjustments when viewing objects at longer or shorter distances than your original setting. Remember to
reset your binoculars back to your personal focus-ring setting.

Center-Focus Eyepiece Binoculars

1. Focus the left eyepiece. Close your right eye or cover the right objective lens. Use the center focus wheel to focus the left lens while viewing an object at least 1 mile away. Mark the scale setting on the center focus ring.

2. Focus the right eyepiece. Close your left eye or cover the left objective lens. Using the right eyepiece focus ring, adjust the focus by viewing the distant object. Mark the scale shown on the body and focus ring.

3. Fine-tune with the center focus ring. When you need to make adjustments as viewing ranges change, use only the center focus ring.

Follow this simple sailing skipper guide to choose the perfect pair of marine binoculars. They will serve you as a faithful companion for many sailing seasons to come--wherever in the world you choose to cruise!

 Hunting Binoculars

Published 2011/1/3 23:58:00 - Ceramic Ball

01. Price Range.

The price range of between $200 and $500 seems to satisfy the majority of hunting enthusiastic. Binoculars costing less than $200 often are found to be lacking in at least one desired feature, while those with prices above $500 may not offer substantial additional features to justify the price increase.

When considering binoculars costing less than $50, durability is suspect at best. Used constantly in outdoor settings one may suddenly find these inexpensive binoculars no longer functioning properly. This category of binocular is probably best suited as a beginning model, or one for occasional general use.

02. Magnification & Aperture.

These are the two numbers associated with all binoculars (i.e. 8X42). The first value ("8") is the power of the binoculars. Meaning that the object being viewed will appear eight times closer, or larger, than if seen with the naked eye. The second value ("42") records the measurement of the front (objective) lens as 42 mm and indicates its light gathering capability.

Theoretically higher aperture ranges are better suited for early morning dawn and late evening dusk viewing. Game often is most active during these hours, and the dimmer light requires higher light gathering capabilities from your binoculars. However, as the size of the objective lens increase so does the overall binoculars weight.

Typically the numbers most often associated with hunting binoculars run in the 8 - 10 magnification and the 40 - 45 aperture ranges (8x40, 8x42, 8x45, 10x40, 10x42, 10x45). In very dim light, you may even want to go to the 50 mm range.

03. Eye Relief.

This is the distance between where your eyes are placed and the rear ocular lens. The recommended minimum distance is 14 mm. Eye relief is important for the comfort of the binocular user, especially if used for extended periods of time. Eyes closer than the recommended 14 mm will cause them to blink more often, thus increasing eye fatigue and discomfort.

Better hunting binoculars have at least 14 mm adjustable eye relief features and normally include twist up eyecups.

04. Lenses Coatings.

Hunters want to clearly see their target without distortions. The best hunting binoculars have fully multi- coated (FMC) lenses. This means that each of the internal binocular lenses has been coated at least twice with anti reflective layers on both sides of all lenses. Lens coatings are necessary to create a brighter, clearer image, and to correct any color distortions.

In this regard, be aware of terms such as "fully coated" and "multi-coated". Multi-coated lens have been coated on only some of the sides of the internal glass. Fully coated lenses have even less coatings. Hunting binoculars that produce the brightest, clearest images almost always have fully multi-coated lenses.

05. Waterproof & Fog Proofing.

Waterproofing and fog proofing are important binocular features because hunters often encounter changes in weather conditions during the hunting day. This can be changes from sun to rain, from warm to cold, or include sleet and snow. The moisture condensation associated with these weather changes are prevented with a solidly constructed waterproof/fog proof binocular. A non-functional binocular (fogged) half way through a hunt can be an extremely demoralizing event.

Waterproof binoculars are purged of their interior oxygen, have this purged space replaced with nitrogen, and are O-ring sealed to create a waterproof/fog proof construction. Fog proofing normally is a by-product of this waterproofing construction. Insist on hunting binoculars that are specifically listed as both waterproof and fog proof. Some models may be designated as "weatherproof" or "water resistant". Be leery of any proofing verbiage that is not specifically listed as waterproof and fog proof.

06. Construction & Use.

Hunting binoculars are often used over rugged terrain where it can be dropped or bumped against a rock or a tree. Look for hunting binoculars that are designated as shock resistant or offer rubberized exterior armoring to help provide physical protection. Also, be aware that significant banging, dropping, or jars can cause damage to the binoculars interior alignment and can weaken the waterproof/fog proof features of the binocular.

While often considered minor at first, binocular neck straps or a body harness can become more important as the day goes on. The neck strap can secure your binoculars closely to your body to prevent it from banging around, while the body harness helps to ease the weight of the binoculars.

A solidly constructed binoculars case provides protection when the binoculars are not in use. And attached lens covers prevent wasted time looking for loose covers. Better class hunting binoculars normally have some shock resistant capability and include (with the purchase) a carrying case and a binoculars neck strap.

07. Closing Thoughts.

A good binocular will enhance your hunts for years to come. Buy the best you can afford for the hunts you are going to make. While binoculars often come down to a personal choice, their initial cost should be computed over the years you plan on using them for your hunting enjoyment.
