I want to buy an astronomical telescope!!

There are a lot of questions similar to the landlord, if you don't know about the telescope, it is also necessary to buy a hot hand of entry-level equipment within 1000 yuan.

For your requirements for telescopes, generally, 1000 mirrors do not match moon mirrors, and solar filters do, which is already the most basic configuration of astronomical telescopes. Considering the current price of raw materials, 1000 yuan to buy a slightly higher quality telescope, the aperture should be 60mm, not larger than this. For example, the Sky Wolf 60mm costs more than 1200 yuan.

The configuration and quality of the average brand, 1000 yuan can sell an 80mm mirror, but the overall workmanship is not ideal.

As for the Saturn rings mentioned by the landlord, you can distinguish them from the 50mm mirror, not to mention that now 80mm is already the mainstream aperture, and there is no problem in looking at the Saturn rings. But a little more detail, such as the Cassini ring seam, can only be seen by a mirror with a diameter of at least 100mm.

Again, the telescope must not be deceived by the maximum magnification marked by the manufacturer. You must know that "caliber is the last word", what is the highest magnification that can be configured with a large caliber, that is a theorem, the highest magnification can be made, if it exceeds the theoretical value, the imaging quality is rotten and bad.

I suggest the landlord to buy Boguan, what else can you ask again.

Astronomical telescopes are actually what you pay for, cheap things, and their quality is really questionable in some ways.

1000 yuan is the ordinary price of a beginner mirror for astronomy enthusiasts, and there are many choices of mirrors around this price, all of which can meet the requirements of the landlord.

I personally recommend the landlord to buy a refractor with a diameter of 80mm (the focal length is reasonable to choose a telephoto and break the focus, and the price of the mirror itself is about 600), with 25mm, eyepiece (different observation objects should use different eyepieces), aluminum alloy tripod (my own 80mm mirror is equipped with a heavy-duty photographic tripod, heavy enough, wind resistance, 280 yuan.) For those who are equipped with an equatorial mount, I advise you not to do it, that kind of equatorial mount is no different from a child's toy, really. ), zenith mirror, moon mirror.

The configuration of this mirror allows you to see the rings of Saturn, and it is easy to operate, making it suitable for enthusiasts with no experience in operating. If you plug in a camera and do astrophotography, you can get a decent image of Saturn's rings.

As for the sunglasses you are talking about, you need to use a professional filter film to observe the sun, you can buy one yourself, and then come back and make it yourself, and the price is relatively cheap.

If you want to be able to see the rings of Saturn very clearly, it is clear that a mirror of 1000 yuan is absolutely impossible.

As for the brand, you can choose a well-known brand in China, and you can choose one that offers you the most discounts or the best service.

If you shop online, I personally recommend going to the newly opened small store of the boss to see, and it will jump to his ** store. As the chief altar owner of the Shepherd Astronomical Forum and a well-known astronomical figure in China, his credibility is absolutely guaranteed.

Beginners use a small refraction (the kind used by Galileo) to buy one OK (see if you have so much silver) Advice: The pursuit of high magnification is a wrong idea, don't buy the mall, don't buy the phoenix, don't buy the recommended brand on the stall: Sirius, Jinghua (Daguan) Boguan.

I don't like to use cows because I have to dim the shaft from time to time.

Didn't you refocus after doubling? Because doubling actually extends the focal length, the focus is no longer in the original position, you have to refocus to see things clearly again, this step can not be saved, besides, you can't save it, it can't be saved, it looks like a blurred scene of big myopia to see things, everyone will want to adjust it.

As for looking at the stars, it is even worse, just like a short-sighted person who can't see the stars when he takes off his glasses, the image of the stars becomes too blurry, so it's normal to not see.

There is no problem with an ordinary astronomical telescope looking at Saturn, but you must first know which one is Saturn in the sky, and you can't look for it. Of course, it is no problem to see Saturn, but the telescope must have a considerable aperture and magnification to see better.

You can go to the North Travel Star Forum to ask Lao Liu (moderator), and directly search for "North Travel Star", Lao Liu is very enthusiastic, I hope you find a satisfactory answer!

I think it's a garbage bar as standard. There's nothing left or right, I'm changing one. And I'm sorry to tell you.

You've been fooled. This can triple the distance. Yes, indeed.

But the stars are too far away to imagine. You add three times the palo and see it with the naked eye.

I think the telescope is definitely 80mm. You triple the baro to exceed the telescope's limit multiple. So it's definitely a blur.

Other than that. Even if you're in the right place. Let's say you add 3 times the palo.

is magnified 200 times. This is because the field of view is smaller than it is together, and the field of view is less bright. I'm sure I'm going to have to look around.

And it's also possible that you're out of focus. If you are in front of the zenith mirror. You see, you are God.

Is it plastic? It's a few dollars a piece, and it doesn't matter if you throw it away!

Due to the increase in magnification, the field of view will become smaller, please make sure that the target is in the field of view** when gabaro, otherwise you may not be able to see it.

Refocus after Gabaro.

Due to the limited aperture, the magnification is not as large as possible.

Theoretically, focusing followed by a high-powered objective should not be a problem.

I haven't encountered your situation, I only have an adjustable lens when I watch it myself, and the others have not been used. I don't understand.

From 6 o'clock to 10 o'clock on the 17th, west of Sheshan, Shanghai, the parabolic steel structure of Asia's largest 65-meter aperture radio astronomical telescope was successfully hoisted. According to the plan, this "giant ear" the size of eight basketball courts will be completed in the second half of this year, taking over the "class" of the 25-meter aperture radio astronomical telescope at the foot of Sheshan Mountain, accurately determining the orbit for China's "Chang'e-3" lunar landing mission next year, and will also "navigate" the Mars exploration satellite in the future. According to the Shanghai Astronomical Observatory, the overall performance of this giant mirror is currently second only to similar telescopes in the United States, Germany and Italy, ranking fourth in the world.

As a major project of "hospital-city cooperation", this radio astronomy telescope was funded by the Chinese Academy of Sciences, Shanghai Municipal Government, and China Lunar Exploration Program, and started construction in March 2010. Compared with optical telescopes, which are equipped with lenses to take images, radar-like radio astronomical telescopes are more like "ears downwind" that listen to the sounds of the universe, and detect the material structure of celestial bodies by receiving radio waves transmitted from distant celestial bodies to the Earth. The larger the aperture of a radio telescope, the higher its resolution and sensitivity, and the better it can capture the faint radio signals emitted by celestial objects.

Therefore, large radio projects must maintain a quiet radio environment within a 5 km radius of the site, free from electromagnetic interference.

The radio telescope is 70 meters high, the pile foundation is 65 meters deep underground, and weighs more than 2,600 tons, but it can rotate in all directions. The main reflector surface used to receive radio signals is made of 14 circles and 1008 high-precision solid panels, and the accuracy error of each panel is controlled at about millimeters, and the smoothness is better than that of ordinary mirrors. Moreover, at the intersection of the solid panel, 1104 actuators are installed, which can be fine-tuned to ensure the overall smoothness under the influence of large gravity.

Hong Xiaoyu, director of the Shanghai Astronomical Observatory, said that after it is officially put into operation, the 65-meter aperture radio microscope will become a backbone observation equipment in China and even in the world, and will be an important member of China's very long baseline interferometric network. The aperture of the "super telescope" composed of multiple mirrors is equivalent to the geographical span between the mirrors, and it is currently composed of four radio microscopes of different aperture such as 25 meters in Shanghai, 50 meters in Beijing, 40 meters in Kunming, and 25 meters in Urumqi. Shen Zhiqiang, the chief scientist of the project, said that when the Sheshan "65-meter" radio microscope replaces the "25-meter", the sensitivity of China's very long baseline interferometric network will be increased by 42%.

In the Chang'e-1 lunar exploration project, the very long baseline interferometric network and the space tracking and control network jointly completed the orbit determination task. When Chang'e-3 plans to release the lunar rover next year, the 65-meter aperture radio microscope will participate in tracking the footsteps of Chang'e-3 on the moon along with the other three mirrors. In addition, after the new mirror is put into service, it will also achieve more accurate positioning and orbit determination in a series of deep space explorations such as Mars and Venus, and measure the instantaneous position of spacecraft in a shorter time.

I checked: In 2016, the 500-meter aperture spherical radio telescope developed and designed by China will become the world's largest single-aperture radio telescope after it is completed in Kedu Town, Pingtang County, Qiannan Miao Autonomous Prefecture, Guizhou Province.

The most important parameters of a telescope are aperture and focal length, and a large number of parameters are very useless. Of the first two parameters, the aperture determines the telescope's light-gathering capacity and resolution, which is the most important parameter.

Another important accessory is the equatorial mount, without which it will be slowly tormented by the celestial movement. In any case, an astronomical telescope always requires an equatorial mount.

Looking at these three parameters, it is enough to choose a telescope.

The following is my own in a similar question, and I personally think it will be helpful to the landlord.

I suggest that the landlord still carefully consider whether to buy a telescope, and even if he wants to buy it, my advice is to buy a small-aperture telescope, such as a Boguan 60 700 refraction (look at a simple celestial body).

Personally, I think there are two reasons, first of all, such a telescope is more than enough to observe the celestial phenomena that are relatively easy to observe, although such a telescope is small, but the power is still not to be underestimated, such a telescope can see Mercury in addition to the moon, the waxing and waning of Venus, the crown of Mars, the cloud belt of Jupiter, the rings of Saturn, Uranus conjunct Neptune, and hundreds of deep-sky objects (the 110 famous objects on the surface of the Messier object are completely tolerant), as well as hundreds of double stars, and some man-made objects.

In addition, such a telescope is relatively small and easy to carry, and it is relatively easy to take out of the city, you know, a small telescope outside the city is definitely no less effective than a telescope with a much larger aperture in the city.

However, I advise the landlord to think twice. After knowing the basic astronomical knowledge, I decided that it would be better to enjoy the more beautiful sky after learning astronomical knowledge. Because I am a little worried that some people only have a temporary interest in astronomy, and observing the starry sky requires a certain amount of astronomical knowledge (some must be laughed at by the star map), maybe not everyone can persevere, and I am afraid that the difficulties will not have a deep understanding if I do not experience it myself.

If the landlord must buy it, it is recommended to buy a refractor, and the reason is see me.

I still hope that the landlord can think carefully and not regret spending the money at that time.

As for the brand, I prefer Boguan, because this brand is more famous, the quality of the mirror is not bad, and there are more service points, and the after-sales service is relatively convenient. Of course, the brands such as Tianluo and Daguan mentioned upstairs are also quite good.

Finally, it is recommended that the landlord go to the manufacturer's website to look at the telescope, or go to several relatively large astronomical forums to communicate. **Lamp** is not completely impossible, but some of the above merchants can promote some incorrect knowledge (the most typical is magnification) in order to sell the meeting, if there is no certain knowledge of the Huai Wen may fall into the trap, buy a telescope that is not particularly suitable for yourself.

The reason why I don't recommend going to a physical store to buy a telescope.

I used to buy a Xingtran 80EQ through **, and I used 800 yuan at that time, and now the price has been reduced to more than 600 yuan, I think this should still be credible. Do not worry.

And the seller's credit rating is 4 diamonds, which can be trusted.

Generally, 3 diamonds will do.

In fact, looking at the nebula, I think the key is not, the telescope itself is decided, the key is to have a good equatorial mount, I bought the 80EQ original equatorial mount, really can only track and track celestial bodies, but can not find celestial bodies, can only rely on experience, star maps and star finderscopes to find. Because the accuracy of the scale on the manual equatorial mount is not enough.

The nebula can actually be seen even at 80EQ, but it is just a bright spot, and to be honest, it is difficult to distinguish it from the star, so it is necessary to rely on an accurate equatorial mount to find it based on the data. Jupiter's red spot, 80eq can barely be seen, but it's not very clear, I have my own ** of Jupiter, I can barely see the big red spot on it, I don't know if lz wants to see?

Addendum: I haven't used the 127eq one, but I'd better paste the photo of Jupiter I took, maybe it is displayed directly here, the proportion and size are a little wrong.

You buy it, absolutely.

What is real or fake is domestic, and if it is 10,000 made in the United States, it is not enough. I vouch for you as a person.

In addition, if you ask if you can see nebulae, some nebulae are very good with ordinary binoculars, such as Taurus M45, Andromeda M31, Orion M42, etc., these are all good opportunities for observation in the Northern Hemisphere now.

Jupiter's Great Red Spot can only be faintly seen after adding a 2x Barrow and PL10 combination, and the effect is not very clear.

That's the telescope I'm using now.

In addition, the ** you gave was obtained by exposure to light for a long time, and you can only see a foggy mass with a telescope, and you can't see the spiral arm.
