1. How to use the dual -Tube Telescope

Step 1: Rotten or folded eye mask

Rotten eye mask: Friends who do not wear glasses to observe the eye masks, and friends wearing glasses observe the eye masks.

folding eye masks: Friends who do not wear glasses do not need to turn over. Friends who wear glasses turn the eye masks when observing.

This is to keep the eyes and eyepiece of the pupils properly. If you stick it too close or too far, you will feel that there is a dark shadow in the vision and cannot get a complete vision circle.

In addition, if a friend who does not wear glasses is observed, the eye mask is not spinning, and the eyelashes can easily be scraped into the eyepiece lens to contain oil, which affects the imaging clarity. The observation will be blurred.

Step 2: Adjust the pupil distance

Many friends say that the Telescope always sees two rounds, and there are black shadows in the middle that cannot be re -coexized, because the pupil distance is not adjusted.Operation method: Well the distance between the two lens cylinders and adjust it to the same distance from your eyes, so that the image can be overlapped.

People of different ages are different. For example, children's pupils are relatively small, and the distance between adults is relatively large.The distance between the two sides of the lens barrel is adjusted to the same distance as the pupil distance, so that the image can be re -observed and there is no dark shadow.

Step 3: Cocume

Slowly rotate the focus wheel focusing and adjust the definition!

Add the visual dialogue:

Some people have different eyes, such as 100 degrees left eye and 300 degrees right eye.After taking off the glasses, you will find that your eyes cannot be clear at the same time, because the eyes have vision.At this time, you can first turn the middle focus wheel to make the left eye clear, and then slowly rotate the right mirror or mirror to compensate for fine -tuning, and the eyes can be observed at the same time.

Generally, most Paul Telescope is to rotate the right -eyed mirror micro -adjustment compensation vision:

Some friends received the Telescope because they were unfamiliar, and when they saw the right mirror or dialogue, they could turn it directly to the end.However, if the eyesight is normal, the difference is turned to the end, so no matter how you rotate the focus wheel focusing, there will always be blurry, and you cannot get a clear imaging at the same time.Therefore, everyone should also pay attention to this. Generally, if you can see the differential ring at the same time, don't move to the end.

Tips:The binoculars on the market are generally divided into roof spine structure and Paul structure. In fact, the operation method is roughly the same. There may be a slight gap between the Telescope of different brands.TelescopeThe manual prevails.

2. precautions for the use of dual -Tube Telescope

1. Do not observe the sun directly with a Telescope, which will cause serious damage or even blindness to the eyes.

2. Do not fall to the Telescope, avoid shocks, so as not to observe the light shaft to be dizzy and bloating.

3. Do not touch the lenses in your hands to avoid affecting imaging definition on the lens.

4. Don't watch the Telescope while walking to avoid accidentally stepped on dangerous objects and cause personal injury.

5. Don't put the Telescope in the car or sunlight under the scorching sun for a long time to avoid the aging of accelerating the rubber at high temperature.

6, waterproof Telescope does not need to keep dry for a long time, which can prevent the lens from growing mold in a sealing bag with desiccant.

7. Do not put the desiccant in the Telescope at the place where the child can get to avoid the child from swallowing the desiccant to cause damage.

8. After using the Telescope mirror, cover the lens cover and eyepiece cover to avoid dust falling on the lens.

Third, double Tube Telescope maintenance contraindications

Although there are a lot of waterproof Telescope on the market, there will be no problem with even if it falls into the water.But in terms of maintenance Telescopes, preservation Telescope in a dry environment is harmless to the baby's coating and Telescope.Waterproofing and nitrogen -filled functions are only in case of water falling and moisture, and they are not afraid of being subject to moisture.RememberDo not use it in rain and snow in non -waterproof Telescope.

Do not try to clear the interior of the Telescope or disassemble the Telescope. The Telescope is actually very complicated. If the light shaft is broken, it must be debugged on the dedicated to debug the light shaft of the Telescope.As soon as the Telescope is disassembled, the light shaft will change, so that the imaging of the left and right Tube will not be overlapped, making your glasses uncomfortable, and in severe cases, you cannot use it at all.Do not fall, pressure or do other violent actions for the Telescope, mainly because of the light shaft of the Telescope, and it is easy to destroy the optical axis of the Telescope.Double -Tube mirrors are the most available impact, especially cheap models.

The principle of Galileo Telescope and optical road map

The objective mirror is a Telescope that can gather lens and eyepiece to diverge the lens.The real image of the light through the refraction of the objective mirror is on the focus of the eyepiece (behind the purpose of the person). This is like a virtual image of the pair mirror, so it is refracted into a magnifying positive image.The magnitude of the Galileo Telescope is equal to the ratio of the focal length of the material mirror to the focal length of the eyed mirror.Its advantage is that the lens barrel can be short and can be positive, but its vision is relatively small.Two Galileo's Telescopes with a low magnification of the magnification are tied together. In the middle, a bolts can be used to adjust its clearly. It is called "Watching mirror"; because it is convenient to carry, it is often used to watch performances.

You can use a very low cost to make a Galileo -style Telescope.Buy a glasses with a diameter and focal length from cultural supplies stores as objective mirrors and lens with a small -diameter and smaller diameter as eyepiece.Use glue and small grooves to put two lenses in the hard paper Tube, and make a simple table, so a Telescope of the mountains on the moon, the stars in the galaxy, and the Jupiter's satellite Telescope can be made.Think about it, Galileo was discovered with this person.But remember, do not directly observe the sun through the Telescope, so as not to burn your eyes at high temperature!Galileo's refraction Telescope has an annoying disadvantage, that is, "fake color" is generated around the bright objects.The disease produced by "fake color" is that the so -called "white light" is not the light of white color at all, but a mixing from all color light that forms a rainbow from red to purple.When the beam enters the objective mirror and is refracted, the refraction level of various color light is different, so the focus of the imaging is different, and the blur is generated.

In 1611, another astronomer Capeller used two dual -convex lenses as objective mirrors and mirrors, which improved the magnification significantly. In the future, people call this optical system as the Campler -style Telescope.The refractive Telescope used now is still two forms.But the "fake color" problem has not been solved.

Lieper is not an astronomer. He never thought that his new installation was aimed at the sky.But not long, the news about his discovery spread.Fortunately, Galileo, a professor at the University of Padova in Italy, learned about it.Galileo quickly created a refraction Telescope.He uses flat convex lens as objective mirror and concave lens as eyepiece.From the light shot from the objects to be studied to a glass lens of the Telescope lens, the objective mirror reflects the light and focuses on it as the focus of the focus, where the glowing image is formed.This is enlarged by the lens of the eyepiece and entered the eye.

[Telescope Buy] How to choose a Telescope price Telescope for the purchase of the Telescope?

Speaking of Telescopes, many people are no strangers because it can be seen everywhere in the current optical market.With the development of productive forces and the improvement of living standards, there are more and more types of Telescope brands and Telescopes, and the output is getting larger and larger, and the price is getting lower and lower. It has gradually become one of the household supplies of many consumers.In recent years, Telescope enthusiasts across the country and even the world have gradually increased. They all want to buy a Telescope with excellent performance, reasonable prices and meet their requirements.However, the Telescope in the market really dazzles many consumers.Many people often know much about the knowledge of Telescopes because of lack of experience in this regard. Therefore, they waste a lot of time and a lot of money, and they still have not bought a Telescope that makes them completely satisfactory.Therefore, we should learn from experience. The so -called confidant and knowledge can be able to fight all the best. Buying things is actually the same principle, especially for valuable items such as Telescopes, we must first understand that we can buy to make ourselves allow ourselves to make ourselvesSatisfied.

1. About multiple: 7-12 times the best, do not want to be greedy.Many people always think that the higher the optical multiples, the better. In fact, the reasonable multiple of a Telescope is related to the caliber and observation method of the Telescope, that is, the large caliber can be higher.Higher than the handheld observation.If you choose a two -Tube Telescope brand product with hand -held observations, it is sufficient between 7 to 10 times? It is best not to exceed 12 times.Otherwise, the higher the multiples, the smaller and darker the observation field, and the observation effect will decrease, especially the jitter brought by the high multiplier will greatly increase, making the observation scene unable to stabilize.Most of the Telescopes of various countries in the world such as China, the United States, and Russia are mainly 6 to 10 times. This is because a clear and stable imaging is the most important.

2. About caliber: The larger the diameter, the greater the observation field and brightness, which is conducive to observation under the light light.But the larger the caliber, the larger the volume, and it can generally be selected between 30 and 50 according to needs.

3. About the field of view: The larger the viewing field, the wider the observation range, the more open and comfortable. The regular military Telescope is generally designed with a wide -angle viewing field.For the binocular Telescope, the more comfortable the view of the view at the same rate, the more comfortable the wide -angle viewing Telescope will give people a wide and comfortable feeling. According to the experience of Wheat fields, it is generally recommended that you buy 110M//Telescope with a field of view above 1000m.

4. About coating: The role of lens coating is to reduce reflection, add light transmission rate, and improve the brightness of observation. The color of the coating needs to be based on optical materials and design. The lighter the coating, the smaller the reflector, and the better.In recent years, there have been various red -film and green film Telescopes that have strong reflection and shiny shiny in various markets, which attracts consumers. In fact, this inferior coating reflex has lost many Lights, which makes the color cold and darkened, and the clarity decreases.What's more, some people actually call this infrared mirror as a "infrared night vision Telescope" that can be used to deceive consumers.The imaging is completely different from the Telescope. It cannot be used during the day, the price is expensive, and the power supply is required to work.

5. What can I see when the Telescope can be seen: This is mainly related to the performance, weather and goals, and judgment standards of the Telescope.According to the test, the Russian 8 30 conventional binocular Telescope can see stones, people's faces, and vehicles driving in a few kilometers when the weather is fine. You can also see the dense ring -shaped mountains on the moon at night., Jupiter's satellites, stars, nebula, etc., friends who are interested in astronomy can try it.In fact, an excellent Telescope brings you fun and use that will often exceed your imagination.

This remote mirror brand is enough to shock people, because it is a professional manufacturer, so it is very good to wait and see.When we choose a Telescope, we can actually distinguish it well, because those who are not very professional are often blown. For example, 80 meters of Telescope with 80 meters is equivalent to 8 meters. This statement is wrong.The merchants can see dozens of kilometers more outrageous. I think a few people can't lift such Telescopes.

6. The identification of regular Russian -made Telescope: In recent years, a large number of plastic shells have appeared in various plastic shells with camouflage, gray, black, white and green, etc., and only use ordinary lenses and prisms. The so -called Russian Telescope is plated with red film, green film, yellow film and other colors.There are northern needles, seat lines, and mirrors with Russian, Russian Party emblems, cannons, red stars, etc.It is tens of times, hundreds of times, or even thousands of times. The so -called "Russian Telescope" of tens of kilometers and hundreds of kilometers can actually be seen.The quality is very poor, and its real multiple is only about 3 to 6 times.The real Russian military Telescope is generally only visible in the border trade area of the Northeast and Xinjiang, and there are not many goods.The Russian -made military Telescope is characterized by the military factory. The all -metal structure is solid and durable. The mirror has a number engraved on the body.BAK4 high -level prism material, wide -angle design is large -view design, the multiple is real, the high -definition optical quality is excellent, which fully reflects the superior optical level of the original Soviet Union.The value is high.

7. About price: A famous Telescope in the international market. Its performance is very good and the packaging process is exquisite, but the general price is more than two or three thousand yuan.You can go to MAIGOO, the top ten brand network of China before buying, to learn about specific brand information. This website not only shows us the top ten Telescope brand lists: https://www.maigoo.com/maigoo/217wyj_index.html, andI also introduced the relevant information of the well -known brand of Telescope.

1. How about the Nikon Telescope

The focus of the Nikon Telescope is accurate. When designing, it fully considers the user's feelings. When wearing glasses, it can also be used normally. In terms of workmanship, it is exquisite in craftsmanship, lightweight, and elegant appearance.All lenses and prisms are multi -layer of coating, and prisms with phase correction coatings and high reflected silver coatings are used to create a super bright and bright field of vision.This is an ordinary Telescope brand that cannot be comparable.In addition, most Nikon Telescope uses a relatively easy -to -operate rotary stepping eye mask (eye mirror eye cup) and uses soft silicone materials to make the grip comfortable and the user feels best.

How to use Nikon Telescope

1. Adjust the distance: adjust the distance between the two lens barrels of the Telescope until the left and right views are a circular viewing field. At this time, the pupil distance between the two lens cylinders is consistent with the two pupil distances of the human eye.

2. Focus: Close your right eye first, use the left eye to see, turn the central institution (hand wheel or pressure plate) of the Telescope until the clear left eye is closed, and the right eye can be seen.Rotate slowly) until it is clear.

3. Observation: Met the Telescope's target for observation, and slowly rotate the central institution, and the eyes can quickly see the target.For targets at different distances, you can see the goal clearly as long as you adjust the medium -adjustment mechanism.

4. Usage of changeable Telescope: First pull the multiplier rod to the minimum multiple, and use the above method to adjust.Until the goal is clear, pull the double pole and select the appropriate multiple you need.Nikon Telescope brand product Daquan & gt; & gt;

Detailed explanation of the parameters of the bilateral Telescope purchase method is to answer what kind of good binocular Telescope

We often hear friends who come to buy a Telescope and ask, "How far can your Telescope look at?", "Can your Telescope be more doubled?", "How can your Telescope be put in the sky?" ...This problem reflects the public's lack of Telescope and astronomical knowledge.

The so -called "see how far" and "how big" are not scientific nor meaningful, and the quality of the Telescope is by no means this way.

In fact, "how far to see" depends entirely on the brightness of the observed target. As long as the goal is bright enough, we can see infinite distance without a Telescope. For example, we can see about 6,000 stars that we can see with the naked eye.In the end of infinitely; and "how big" is the problem that the basic knowledge of astronomy will be raised, this is because we see "the stars in the sky" or more are stars, and the stars are so far away from us, soEven if they are observed with the largest Telescope on the earth, they are still just geometric highlights (the smaller the highlights, the higher the quality of the optical imaging of the Telescope; on the contrary, if you see the stars in the Telescope, the stars have vision noodles or even the color, then there are colors, then there are colors, then there are colors, then there are colors, then there are colors, then there are colors, then there are colors.It can be determined that its optical system is seriously ill). Only the celestial bodies in the Solar system (such as the Solar, planets, satellites, comets, etc.) or the celestial body (such as Nebula, Galaxy, Star Group, etc.) outside the Solar system can use the Telescope.

So is the "magnifying multiple" the performance indicators that must first consider when buying a Telescope?Definitely not!Not only does it not be ranked first, but if it is too large, it will cause the image quality to worsen seriously.

Betal (Yisuke is 8 times to 10 times)

The Telescope is marked with the words of 10 x 42, 8 x 30.Look at a 10 -fold Telescope to see a bird standing in 100 meters, as close to 10 meters with the naked eye.Due to the large rate of multiple, the smaller the perspective, the more difficult to search for the goal, and it is more likely to affect the clarity due to the trembling of the hands.When the light is very sufficient, it is clearly 10 times compared to 8 times; when the light is insufficient, 8 times can see the details than 10 times, so you should not blindly pursue a high mortar rate.

Activation (Yisuke 30mm to 42mm)

The larger the diameter, the better the diameter of the objective mirror affects the amount of light.Especially in the case of strong comparison of light and darkness, morning and dusk, and cloudy, the larger the diameter, the higher the light inlet, the more details can be seen in the eyes; but at the same time, the heavier the Telescope, and the long -term watching is more difficult to cause fatigue.It is advisable to choose a larger caliber according to your personal body.

Vision (the bigger and better)

The field of vision refers to the range that can be seen at 1000 meters. The width of the field of vision should be higher than 104 meters, which is 6 degrees.The greater the vision, the faster and easier to search for the goal.However, when the field of vision is larger, the more serious the edge is distorted and blurred. The more complicated the correction of the aberration, the higher the required technology and cost.

color guarantee (the better the more natural, the better)

High -quality Telescope must faithfully reflect the primary color and saturation of the scenery.In order to increase the brightness of the Telescope, some manufacturers deliberately increase or decrease a certain optical waves, causing distortion to make the scene blue or reddish.

The relationship between light transmission and coating is inseparable and directly affects color conservation.All optical glass high light transmission and full surface multi -layer coating, the brightness is relatively high, and the color is accurate.Generally, manufacturers will not announce all data (it is difficult to do), and some manufacturers will announce the light transmission or coating of local optical glass to mislead consumers.

Use performance

Depth of field

For the bird watching people, the depth of field is a more contradictory parameter. The depth of the field does not need to be frequent, it is more convenient to use, but for observing the forest birds, the prospects and backgrounds are not easy to blur.protrude.The depths of the field are small. Although the forest and birds are obvious and the background blur is obvious, and the theme of the birds is prominent, when the distance changes, it is necessary to re -focus. The fingers must always be on the coking wheel, which is more tired.This depends on personal preferences, there is no fixed standard.

Sealing

Wangyuan is often carried out outdoors. Observation environment is changing. It is best to choose a Telescope with water -proof water (water pressure and waterproof), so that the interior of the mirror can be kept sealed and stable.

Comfortable

Comfort varies from person to person.Generally speaking, the Telescope of the surface of the surface not only has good shockproof effects, but also more comfortable to hold; the weight of the mirror body determines whether it is convenient to use and carry for a long time; usually, everyone will choose a Telescope with high durability.
