[Use of astronomical Telescope] How to use the astronomical Telescope to use the correct use step and guide

1. Install a astronomical Telescope according to the instructions.

2. Regarding the focus of the Telescope and the calibration of the cross -line mirror

Loose two fastening screws on the eyepiece.Take out the low -duty mirror and put it on the eyepiece to pick up the cylinder, and then tighten the screw.The adjustment of the focusing knob can obtain a fuzzy image of an object A in the distance, and then slowly adjust the coke knob back and forth until the object image is clear.The Telescope has accurately adjusted the focal length, and now it can be observed with a star -seeking mirror.If the astrology mirror is not at the focal length, turn the eye mirror until a clear scene appears.When the object of object A you see on the Telescope is not in the center of the star mirrors, according to the following method: tighten or release the screw on the star -seeking mirror support, so that the star -seeking mirror up and down, left and right workers, left and right workers, left and right workers, left and right workMove obliquely.When the object of the object A appears in the center of the cross line, your star -seeking mirror is ready, and finally the three screws are tightened.Then replace the low -power mirror with a high -power mirror and repeat the above program.If the center of the image observed under the maximum mirror and the cross -line center of the star -seeking mirror, your star -seeking mirror is adjusted.Now you can quickly find the celestial body you want to observe.In extremely special circumstances, star -seeking mirrors may need to be adjusted.

3. precautions

A. Under any circumstances, first look for objects with a star -seeking mirror, because the perspective of the star -seeking mirror is greater, which can greatly accelerate your coarse tone.

B. Under normal circumstances, first install a low multiplier mirror to gradually increase the multiple you need, and you need to make the necessary focus when you change the mirror.

C. Don't be troubled by the upper and lower, left and right images that you see, this is a normal situation for astronomical Telescopes.

4. Effective observation notice

If the Telescope gets outdoors for the first time in air with lower indoor temperature, it must be used for a few minutes-because the temperature difference will make the lens blindfold.This phenomenon will disappear after 15-20 minutes.If your eyelids or fingers touch the eyepiece, the cloth that can't afford the hair will be gently wiped to see the mirror to prevent blurred images.It takes about 30 minutes to enlarge your pupils to adapt to darkness, so use a Telescope at night. After half an hour, you can see a much dark celestial body.

5. Various factors that may affect the observation results

Observation results are not all taken in the optical properties of the Telescope, and many factors also affect the quality of the image.

A. The atmosphere surrounded by the earth is always moving. This kind of atmospheric movement and rotation will cause bad images at a high rate. Perhaps after a few nights, the observation will improve.

B. The heat on the surface of the earth will also cause the fluctuations of the air and make the image distort and deform, resulting in poor observation.

C. The observation angle of the Telescope and the star and horizon has a great impact on the observation effect: if the star body is close to the horizon, the goal will be blurred.

D. Pollution of light sources: use your Telescope (such as under street lights, under room Lights, etc.) as much as possible in a light -free environment, high -mortar astronomical Telescope is very sensitive to light.Even more obvious, it seems that many stars will disappear over the urban area.

E. Moonlight may also be another factor that affects observation. The dazzling full moon or bright moonlight will blur the nearby stars or planets, and the moon itself is the best observation state between darkness and Tianming.

f. Try to avoid observation from opening the window (let alone observation of closed windows), especially in the cold season, the indoor and outer temperature difference can be worse, which will make the observation quality worst.

G. The cloud layer accumulated in the sky cannot penetrate the observation, but this cloud will often move.

H, star flashes are caused by air convection, which will also affect observation.

Remember, in any case, do not directly observe the sun through a star -seeking mirror or main lens barrel, otherwise it will seriously damage your eyes.

Astronomical Telescope purchase guide

Types of astronomical Telescope

The Telescope is usually focused by a telephoto mirror (main mirror) to focus the image of the celestial body, and then uses a (short focus) eyepiece to enlarge this image near the focus.Generally speaking, Telescope can be divided into three categories: refraction Telescope, reflecting Telescope and refractive Telescope.

Refractor

Generally, the objective mirror that reflects the Telescope is composed of two different discounted glass lenses to reduce the color difference and make the red and blue images gather on the same focus. This type of lens is called Achromatic lens.Strictly speaking, there is still a very lilac halo in the periphery of such lens images.

a. Blu -ray focus.

b. Huang Guang's focus.

c. Red light focus.

The color difference between the red, green and blue color of the Telescope.

In order to reduce the spherical difference of the lens, the comets and the AstigMatism can generally increase the focus ratio, so the caliber and focal length ratio (coke) of the longoscope generally reflect the at least from F10 toBetween F16.

The higher -level lens is composed of three different discounted glass lenses or made of lower -color (ED) or even fluorite crystals to eliminate the color difference between red, green and blue.These lenses are called apochromat.Their caliber and focal length can reach F5.The length of the Telescope is shortened and the weight is light, it is more convenient to use, but the price is very expensive.

Because the refraction of the Tube can be sealed, it is more convenient for maintenance, and it is more suitable for moving to the wild without being affected by the airflow of the lens barrel.

Because the lens is composed of at least two pieces of glass, the cost (four mirrors) is more expensive than the reflected Telescope with the same caliber.The small astronomical Telescope sold on the market is mostly refracted Telescope.

Reflector

The reflection Telescope is to focus on a concave glass plated (usually aluminum) plating (usually aluminum). Because the focus is in front of the mirror, it must be used to reflect the image outside the lens barrel with another mirror before the focus of the object mirror, and then use the eyepiece to put it large.

There is no color difference in the reflection Telescope (not scattered because it does not need to be through the glass), but there are other types of aberration.If the reflection concave surface is grinded into a parabolic, the spherical difference can be eliminated, but it is seriously affected by the comet shape, so the edge part is still loose.

At present, there are two types of small and medium -sized reflecting Telescopes:

Newtonian

A 45 -degree plane mirror (Flat or Diagonal) with a piece of light shaft is used as a secondary mirror to reflect the image to the front side of the lens barrel.This structure is the simplest, the image contrast is high, and the most people are selected. Usually Job is between F4 and F8.

Cassegrain (Cassegrain)

Use a Convex Hyperboloid as a secondary mirror. Before the focus of the main mirror, the light is gathered, and the main mirror is focused on the main mirror through the main mirror.Because after a reflection, the lens barrel can be shortened, but the field of view is narrow, like a lot of dispersion than Newton. At the same time, there are a little Curvature of Field.

Because the reflective Telescope only needs to grind a optical surface, in terms of the same caliber, the price is cheap than the refractive mirror.Ordinary astronomical enthusiasts have a lot of 150mm and 200mm caliber, and reflex Telescope can be worn at the same time.

Because the lens cylinder cannot be sealed, the main mirror is very easy to be affected by smoke and dust, so it is difficult to maintain. At the same time, it is greatly affected by the temperature and the airflow of the inside of the lens.The light shaft is also quite complicated, and it is not convenient to bring.In addition, the diffraction effect of the auxiliary mirror seat will make the star image of the light stars appear a cross or star -shaped diffraction pattern, and also reduces the image contrast.

CatAdioptric Telescope

This is a type of Telescope that uses the principles of refraction and reflection at the same time. It was used as astronomical photography by Schmidt in 1930.The main thing is to use a spherical concave mirror as the main mirror to eliminate the comet shape difference, and at the same time, a non -spherical lens (ASPHERIC INS) is appropriately placed in front of the main mirror as a correction mirror to correct the spherical difference between the main mirror.In this way, you can get a wide -torment (up to 40 to 50 degrees) fields without the common spherical difference between the spherical difference between the common reflex mirror. Only the mild color difference made of the correction mirror.The Schmidt Telescope for photography can be very small (usually from F1 to F3, minimum can reach 0.6), so it is very suitable for Hoshino and Nebula photography.However, the only disadvantage is that there is a certain venue, so the negative must also be changed to adapt (undertake with a special negative seat), and at the same time, the negative is placed in the long -distance lens barrel, so it can only be put in.

Generally, astronomical enthusiasts use Schmidt-Cassegrain (Schmidt-Cassegrain). It uses a convex mirror as a secondary mirror to gather the light before the main mirror focus.after.Because of a reflection, the lens barrel can be shortened, usually between F6.4 and F10.

In addition to the Schmidt-Cassegrain, there are also Maksutov designs.A round hole focuses on the main mirror.In recent years, the popular spinning Telescope such as "Celestron" and "Meade" are composed of Schmidt-Cassegrain principles, while "Questar", "Meade" ETX series and "Intes" use Mark Su.The principle of Toff.

The mirror body of the refractive Telescope is short, the focal length, and the focus is behind the main mirror, and the field of view is quite flat.In terms of contrast).

How to use the Telescope and maintenance skills

Many people have Telescopes, and even many friends have military Telescopes. Although they have such good things, many people do not know how to use them and how to maintain them. Today, they answer questions for everyone.

How to use the Telescope:

1. Adjust the distance of pupils

First of all, my Telescope is a rotating eye mask system. When used, the eye cover is rotated to the highest (generally operating this). If you bring glasses or when you are at the highest of the eye maskShadow (shadow), you need to adjust the eye cover to the most comfortable height of your glasses.

Second, adjust the distance between the program

Change the distance between the Telescope two lens cylinders, until the left and right views are a circular viewing field.At this time, the pupil distance of the outlet of the two lens cylinders was consistent with the two pupils of the human eye.

3. Focus

First rotate the middle -tone agency's handwheel of the Telescope until the left eye can see the target clearly.Then turn the vision of the right mirror, so that the right eye can also see the goal.

Fourth, observation

The Telescope is roughly observed to observe the goals, and the central institution is turned, and the eyes can quickly see the target at the same time.For different distances, as long as you rotate the central institution, you can see it quickly.

Notice:

With Bi, the rotary eye mask must be put down back, otherwise it may hit a bad rotation eye mask because of negligence.

Because of the focus function of the Telescope, it is not suitable to observe the bright objects, especially the sun, which will damage your eyes.

maintenance of the Telescope:

1. Do not wipe the mirror or eyepiece mirror with other ordinary cloth, use the velvet cloth or other soft cloth to wipe the Telescope mirror mirror with a Telescope bag.

2. When removing the residual dirt or stains, you can drip one or two drops of alcohol. It is best to use a cloth to dip, because the drip is not easy to control.

3. Although everyone buys a waterproof mirror, there will be no use problems even if they fall 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.

4. Don't try to clear the interior of the Telescope or disassemble the Telescope. The Telescope is actually very complicated. The light shaft is broken on the dedicated to debug the light shaft of the Telescope to debug.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 other severe actions of the Telescope, mainly because of the light shaft of the Telescope, and it is easy to destroy any glasses in the light shaft of the Telescope.Please send it to me, help you repair it for free.

5. Do not observe the sun directly with a Telescope. This is a major precautions of all Telescopes. The strong sunlight through the focus of the Telescope, just like a magnifying glass, will burn your eyes.

6. Due to cost and self -weight, carry light consideration, most of the current Telescope is not a metal mirror body. It falls heavy, heavy pressure, and it is easy to damage.So everyone should love her like a Dog.

7. The desiccant I match is actually not meaningful to the waterproof Telescope. After a year, I will be thrown away.However, it is best to replace it regularly (half a year to one year) to prevent the internal moisture.The desiccant should be available, and some products are also available, which can be borrowed.

8. After using the baby, first look at the foreign body on the table when placing it. Do not place it on other items to prevent scratching or staining mirrors and eyepiece.

9. The Telescope still should be put on the drip. Do not put the eyepiece down.(Everyone on the earth!), Because some parts are painted with lubricating oil, and some places are designed with oil grooves. For a long time, the inverted time or the weather is too hot, and it may flow to the place.

1. What does infrared Telescope mean?

There are many types of infrared. Most of the microcariar night vision also have infrared functions. Its infrared is a short wave infrared, which is longer than visible light, similar to remote control.The purpose of this night vision design is to use infrared lighting, so it is not easy to be discovered (enemy).There is also a thermal imaging. Thermal imaging actually collects the infrared from collecting hot objects. However, this infrared wavelength is very long, and the general microcariae night vision instrument cannot be seen.The advantage of thermal imaging is that it can effectively observe the heat source, such as mammals, cars, etc., which is very useful in military.

2. Principles of Extramaginal Telescope Imaging

You can see the infrared Telescope, which is the band of infrared rays((wavelength8001 000Nm)The Telescope.It is also one of the night viewing Telescopes in military applications.Of course, the infrared Telescope is applied to astronomical observations.The infrared Telescope converts the infrared rays into electronic flow through photoelectric transformation, and then doubles the electrons. Finally, the electrons are hit on the fluorescent screen and turned into visible light.As long as there is temperature, infrared rays will be generated, he is a special lens that can pass and display infrared rays.

3. How much is the infrared Telescope

Like the movie, you can see the enemy clearly at night without light. Only the military active infrared Telescope.Russia is cheap and good quality. Among them4800RMB, if you can buy it in China, it should be in6000above.If it is lower than5000The active infrared night viewing Telescope should be a bit problematic. It is recommended not to buy.

4. Can infrared Telescope be seen through?

cannot.Because our human body has body temperature radiation.No formal manufacturer's manual says that I am"Perspective Telescope".Only said it is night vision Telescope.

Fifth, the red film Telescope is the infrared night vision mirror?

The Telescope, not to mention civilian, military useless Telescopes of night vision, the movie is just a movie.For red or yellow coating, many illegal vendors publicize that "night vision effects, infrared" and the like are actually false propaganda.It is a kind of decoration -has no night vision effect. In fact, this decorative coating also makes the field of vision dark.So except for the previous processed samples, other red film products have not been provided.Although the Telescope of red film, although the brightness and color deflection are not as effective as other coating, because the appearance is good, even as a regular military industry (foreign trade) manufacturer, there are a small proportion of exports.But the problem is that in the domestic chaotic Telescope market, most of the red and yellow -coated Telescopes are not from such regular manufacturers, but some small workshops, in order to deceive the propaganda (so -called "military"/"Russia",/"Japanese cherry blossoms"/"night vision"/"infrared") produced, that is, most of them are inferior products of small workshops.

Explain the top ten Telescopes worldwide in the world's top ten Telescope shooting pictures to appreciate

On October 2, 1608, Dutch officials were carefully thinking about a patent application. This is a invention submitted by the owner of the glasses shop owner Hans LipperShey.The object looks like it is around, and it can magnify the objects and scenes through it.This is the earliest concept of Telescope.A few months later, Italian physics and astronomer Galileo took a Telescope for astronomical observation.

The initial Telescope was very simple. It was composed of a very small lens and placed in an internal empty wood pipe with a long arm.However, today, 400 years later, the world's largest Telescope requires built on the towering mountains. Several tons of steel is used to support huge mirrors, so that scientists can observe the vast area of space.In June 2008, at a speech conference held by an astronomer, Dava Sobel claimed that observing space through Telescopes was one of the most outstanding achievements in human beings as a life form.

The following is the top ten largest astronomical Telescopes in the world. The photos of these are the largest optical/infrared Telescopes on the ground.

1. Gran Telescopio Canarias

Gana Large Large Telescope

At present, the world's largest ground basic Telescope is the large Telescope of Gasana. It is located on a small island in Parmaga Islands, Spain. It is said that multiple large Telescopes are placed in the Gaza Islands.The mirror diameter of the Telescope is 10.4 meters, which is composed of 36 custom mirror hexagonal components. The installation requires accurate to a range of 1 mm.It invested a total of $ 175 million, jointly built by the Spanish government, two Mexican research institutions, and the University of Florida.

Before installing the Telescope component, each component was named the name of the gods in the folk legend in the local islands, or named after the island's animals and plants.

Pictures shot by Garn Large Telescope

The last batch of 36 mirror components of the large Telescope of the Gana column was completed. However, its first appearance was in July 2007, when only 12 mirror components were installed.The first star it observes is the "Tycho 1205081" (Tycho 1205081), which is very close to the North Star. After that, this large Telescope has more captured astronomical pictures to shoot a set of interactive galaxies -UGC 10923.The results of each shooting show that the star formation area expands, and the exposure time of the shooting is 50 seconds.

2. Keck Telescope (KECK I & amp; ii)

Kake Telescope

W. M. Kay Telescope is located on the top of Monakia Mountain in Hawaii, 4200 meters above sea level, and Kike I & amp; II is two exactly the same Telescope. They are composed of 36 mirror hexagonal components. The overall mirror diameter is 10 meters.The diameter of each mirror is 1.8 meters, and the thickness is only 10 cm. By actively optical support system, the mirror surface maintains high accuracy.There are three main devices of the Telescope: near infrared camera, high -resolution CCD detectors and high -colored scattered spectrometers.

Each Telescope is 8 floors height and weighs 300 tons. At present, astronomical observation accuracy can reach milliligns.In 1993, the Kike I Telescope was put into use and used scientific observations.In order to use the Telescope for 1-5 nights, astronomers must be approved by the committee in advance and operate the Telescope with the assistance of the committee. Generally, astronomers collect data from the headquarters of the Observatory headquarters in Waimea, Hawaii.

Pictures taken by Kake Telescope

By canceling the distortion and deformation in the atmosphere, the recent adjustment of the adaptive optical system has improved the ground basic astronomical observation ability of the Kake Telescope, and the observation picture is 10 times clearer than before.For example, the Egg NEBULA (Egg Nebula) of the Egg Nebula (Egg NEBULA) is a synthetic picture.When more and more substances on the surface of the star begins to get rid of, the surface becomes more hot, making UV light electricity from becoming a gas, thereby showing beautiful colors under the Telescope observation.The planet can be formed after thousands of years.

3. Large -scale Telescope in southern Africa

A large Telescope in southern Africa, referred to as SALT, is located on a hill on southern Africa. It is the largest single -optical Telescope in the southern hemisphere.It is composed of 91 mirror hexagonal components. The overall mirror is actually effective in diameter of 10 meters.The Telescope can detect the weak light of the moon distance like a candlelight, and the Telescope was first put into use in 2005.Astronomers from South Africa, the United States, Germany, Poland, the United Kingdom, and New Zealand have used large Telescopes in southern Africa.

Pictures of large -scale Telescope in southern Africa

Is this picture showing "the universe Nirvana Phoenix"?In fact, this is the scene of the three galaxies collision mergers. Before the astronomers called this picture "Big Bird", and identified this is just the merger of the two galaxies.It is the result of the collision of the three galaxies, and there is a clear separation material area on the head of the "Big Bird".In order to establish this picture, the large Telescope in southern Africa use its spectrum camera to provide valuable observation materials to the Telescope association, and the spectrum camera can decompose the light into a structure color.This may be used to study the physical condition of the galaxy and the detailed situation of the movement path during the three galaxies.The separation speed of interstellar matter in some areas of the "Big Bird" exceeds 400 km/s.It is very rare to observe such high -speed Running interstellar substances that can be observed in the combined galaxy.

4. Hobbie Enley Telescope

Hobbie Eberi Telescope

Hobbie Enlie Telescope is located in the Favaks Mountain in Texas, USA, referred to as Het, which is very similar to large Telescopes in southern Africa.It is composed of 91 mirror hexagonal components. Each mirror diameter is 1 meter, which is continuously sorted by a small computer control motor.The overall mirror diameter can reach 11 meters, and the actual available is only 9.2 meters.The Telescope can detect cosmic light of 100 million times darker than the human body.Its design and construction adopt a unique way to enable it to absorb large light, especially spectrometers, and its cost is very low.

Pictures taken by Hobbie Enley Telescope

The Hobbie Eberi Telescope can observe the layman star and gamma rays of the Solar system. It is currently used to observe the mysterious substance of the universe that humans cannot see-dark energy.In the three-year special plan "HETDEX" (Hobbi-Eberi Telescope dark energy experiment), the Telescope can observe more than 1 million galaxies from 9 billion light years away, so that it can be drawn to the largest so far so far so farThe universe map.This universe map allows astronomers to measure the expansion speed of the universe in different periods, hoping to reveal the role of the dark energy of different cosmic era. At present, the Telescope will search for the universe area where the Dabei star is overwhelmed.

5. Large dual -Tube Telescope

Large dual -Tube Telescope

Large binocular Telescope is referred to as LBT, which is composed of two tightly adjacent 8.4 diameter Telescopes. They can work separately. When the merger work is like a single, larger Telescope.The first Telescope was set up on the top of the Graham, Arizona, USA in 2004. The second Telescope was installed since 2005. It was not until early this year that the two Telescopes were observed.

Pictures of large binocular Telescope shooting

The first picture was taken in the large binocular Telescope, showing the NGC 2770 galaxy, which is 102 million light years from the earth.This is actually a synthetic picture: the same scene is taken with ultraviolet rays and green light, respectively, showing the activity of stars in the area. At the same time, the red light area shows the older and colder stars.After the merger of such three pictures, a beautiful picture can be formed, which can show the different characteristics of the star body at the same time.

6. 6 Telescope

Telescope

As shown in the figure, this is the half -mountainside of the Mountains of Monakia, Hawaii. The diameter of the Telescope is 8.2 meters. These are a optical/visual infrared Telescope.The mirror surface is thin, and the high imaging quality is obtained through active optics and adaptive optics; the second is to achieve high -precision tracking; the third is to use a cylindrical observation room to automatically control ventilation and air filter, so that the exclusion of hot turbulence can achieve the best conditionsEssenceThis Telescope uses a Serrurier truss to keep the main mirror frame and the auxiliary frame keep parallel in movement.

It can share the observation data of other Telescopes with the Kaike Observatory.It has the largest single -lens in the world today, and its use rights belong to the National Observatory of Japan, but astronomers from all over the world can use it.The name of the Telescope comes from a young star group- "Pleiades".The first scientific observation was conducted in 1999.

Picture of Telescope shooting

This is the gorgeous and clear infrared picture of the S106 star in the S106 star.The maximum quality star in the regional center is called IRS4. It has a history of 10,000 years and its quality is 20 times that of the sun.In addition, astronomers have found that the quality of many stars is lower than the twins in the area, and they are likely to be brown dwarfs.

7. The European Astronomical Observatory is a big Telescope interference instrument

The interference instrument of the southern observatory of Europe

It is a 48.2 -meter diameter Telescope structureCheng, located on Mount Sear Parana, Chile, can operate alone or form a very large Telescope interference instrument.The instruments assembled in the big Telescope can provide detailed observation materials and capture the changes in the star body movement of one billionth.This combined astronomy observation can detect cosmic light 4 billion times more visible than the human body.

Pictures taken by the Da Ling mirror of the Southern Observatory of Europe

Very large Telescope helps astronomers to observe the "fried circle cake" structure shown in the figure, which is considered to be a large quality black hole at the center of many galaxies. Generally, the area near the black hole is very bright.Several Levels of brightness.Indirect evidence tells that astronomers are a gas and dust structure with thick frying circular cakes, which are wrapped in black holes.No one of the astronomers had previously observed the star structure.In 2003, astronomers used very big Telescopes to reveal the mysterious veil of the fried circle cake structure of the NGC 1068 galaxy center.

8. Gemini Telescope

Gemini Telescope is not two tightly adjacent Telescopes. This is two 8 -meter diameter optical/infrared Telescopes, which are located on the east -west hemisphere.The Telescope located in the northern hemisphere is coordinated with other Telescopes in Monakia, Hawaii. The Telescope located in the southern hemisphere is located on Mount Siro Parana, Chile.Place the Telescope in two hemispheres for easy observation of all -weather systems.Its main mirror uses active optical control, and the auxiliary mirror is quickly corrected as an inclined mirror. It will also use the adaptive optical system to make the infrared area close to the diffraction limit.

Picture of Gemini Telescope

It impressed the astronomers.This is likely to be the first picture of the planet surround another star. Astronomers did not eventually determine whether the star actually surrounds a young sun star.If it is a planet, then it will be a behemoth in the planetary family, and its quality is 8 times that of Jupiter.The distance between it is 330 times the distance between the earth-Solar distance. Compared with it, the sea king star in the Solar system is only 30 times that of the earth-Solar distance from the sun.

9. Multi -mirror Telescope

Multi -mirror Telescope

Multi -mirror Telescope is referred to as MMT. Before the main mirror surface is installed, 6 small mirrors are used. This 6.5 -meter diameter main mirror has a specially inferior honeycomb design.The multi -mirror Telescope is an art -level building, and it does not have the dome structure of the traditional observatory.This unique appearance makes the walls, tops, tops and Telescopes of the Observatory's wall, and Telescopes can quickly cool down the Telescope and improve observation efficiency.At present, Multi -mirror Telescope is located on Hopkinson Mountain, Tunson, Arizona, USA.

Multi -mirror Telescope shooting pictures

Because it is in the galaxy, it is difficult to observe the structure of the Milky Way, but the multi -mirror Telescope (referred to as MMT) can help us better observe the "twin brothers" of the galaxy -Triangle Star -based (referred to as M33).Although this galaxy looks very much like the galaxy, it is actually smaller.There are 200 billion stars in the galaxy, while only 10-40 billion stars in the triangle galaxy.Astronomers use multi -mirror Telescopes to establish three -dimensional maps of galaxies, which is conducive to searching for exterior planets and detecting ancient stars in the current period of the universe.

10. Magellan I & amp; II Telescope

Magellan Telescope is currently the latest bilateral Telescope. Two Telescopes are 200 feet apart from the heights of the Atkama Desert in Chile.The 6.5 -meter diameter mirror of the Telescope floats on a high -pressure oil film, and its friction is small, and children can promote this 150 -ton Telescope.However, no astronomer wants to slide the mirror, so driving the cylinder and the driving plane can form a pressure of 10,000 pounds to keep the mirror stable.

Pictures taken by Magellan Telescope

The 8 Zhang Magellan Telescope is combined to form this dazzling picture, which is called "Thor's helmet".This is shot by the spectral camera of the Magellan regional camera using the "Inamori) Magellan regional camera and assembled 8 megapixel CCD detectors.As a result, as a Wolf-Rayet Stars, its surface temperature can reach 25,000-50000 Kai Kai's temperature.
