How much does a Gekyer 70400 type astronomical telescope cost?

Gskyer Skywatcher 70400 telescope? The price of this mirror on a certain treasure is around 470.

If you are a novice, the biggest problem is not what kind of astronomical telescope you recommend, but that after you buy it, it may be too different from what you imagined and idle.

Many people think that astronomy is interesting and think that they like astronomy, but in fact, it is because they have watched some advertisements, or astronomical **. But in fact, the actual use of astronomy is a different matter entirely. About astronomical telescopes, maybe there are too many misleading things in the movie, maybe there are too many irresponsible advertisements, and many people who have not been in contact with it have a misunderstanding that they think they can see colorful nebulae - in fact, it is the effect that can only be obtained by using a professional SLR camera, and a sophisticated electric and equatorial mount to track ** for a long time.

Even if it is an astronomical telescope of tens of thousands of yuan, observers cannot see as colorful as those.

When the astronomical telescope actually observes, in addition to observing the moon is more interesting, looking at the planets can have disks, and looking at the stars is the same as the naked eye, they are all small dots, but the number of them is more; Without a DSLR CCD, a brilliant nebula looks like a cloud of mist. I'm worried that you might regret buying it like most people.

It's a misspelling, it's a gskyer. **As much as you can out. In addition, this is not recommended to buy, toy grade.

80EQ for various brands (Syntelem, etc.).

The budget of 1000 is just right (in fact, there is still a spare), an entry-level astronomical telescope, the serious kind, not a toy.

If it is a scanning electron microscope, it may be helpful in physics, but the general electron microscope is used in biology, and it may also be used in material chemistry; Astronomical telescopes, as the name suggests, are used in astrophysics. Hope it helps

One is biology and the other is physics!

There are too many lessons involved.

For example, astronomy, mechanical engineering, optics, physics, chemistry, mathematics, computer technology, geography, ......Uh, that's too much.

Modern society is a cooperative society, and cutting-edge science and technology are almost the crystallization of multidisciplinary cooperation.

Physics.

To study astronomical telescopes, you should have a very professional knowledge of light, refraction, diffuse reflection, diffraction, dispersion and other very professional physical knowledge, so you should work hard in this area.

Beijing Galaxy Telescope Answer:

The gap between astronomical telescopes is very large, and our ordinary junior astronomy enthusiasts can choose non-professional mirrors (professional mirrors are very expensive, and they are generally used for professional observation). **In the 1000-2000 yuan or so low-end astronomical telescope can be, of course, if you are very passionate about astronomy, for the observation effect of high requirements, you must choose the high-end telescope, refraction and reflection have their own advantages and disadvantages, mainly depending on what you want to observe, choose the best one for yourself;

The refractive aperture is relatively small, the focal length is relatively long, and the realization multiple is relatively high, which is more suitable for seeing the single planet and details, but it is easy to maintain, simple to operate, and the low-end refractor is relatively cheap, which is more suitable for beginners.

The reflective type has a large aperture, a short focal length, and a relatively low realization multiple, which is more suitable for seeing a large area of the starry sky, with a large observation field and no chromatic aberration, but it needs to be coated once every five years.

The realization multiples mentioned above are relatively speaking, the magnification of astronomical telescopes is directly related to the eyepieces, and the eyepieces that are standard with each model are different and cannot be generalized. For beginner astronomy enthusiasts, it is still recommended to choose the refractive type.

For entry-level astronomical telescopes, the Centron 90EQ (refractive type) and 130EQ (reflective type) are both good choices.

90EQ This can see the crater on the surface of the moon, can see Saturn, Jupiter, Jupiter moons, etc., can also view the scenery, can see the trademark of one or two kilometers of air conditioning, this basic configuration is very good, the imaging effect is also great, ** at about 1600 yuan.

130EQ can see the craters on the surface of the moon, Saturn's rings, Jupiter, Jupiter's cloud belts, Jupiter's moons, etc., and 130EQ is basically a civilian astronomical telescope that can shoot nebulae with the lowest aperture requirements after being connected to the camera. **Around 1500 RMB. The relative aperture of 130EQ is large, and the observation field is large.

You can go to the Galaxy Telescope Knowledge Zone to see, you can directly search for "Galaxy Telescope", there is a lot of relevant knowledge about the purchase, maintenance and use of telescopes.

It may disappoint you, first of all the equatorial mount is a problem, and secondly that it is too heavy. If you want to see the scenery, use birding glasses or high-quality ED binoculars!

How far to see is such a loose question that it simply can't.

Theoretically, any telescope can see infinity, and some distant stars are invisible because of brightness, not distance. Like the Andromeda Galaxy (M31), which is quite far away from us, it can be seen by the human eye in places with little light damage, let alone telescopes? It can be seen millions of light-years away, let alone objects on the ground?

It can only be up to the conscience of the shopkeeper who bought your telescope.

The Astronomy Bar has the answers you need, but don't be unreasonable and ask boring questions that will shut you up!

Passing by, let's talk about the telescope.

100mm ED. Generally, it is an astronomical mirror, and a single tube costs more than 10,000.

80mm ED. There are birdwatching scopes to choose from, but it is recommended to use an astronomical scope, with high flexibility, many eyepieces to choose from, **5000, you can choose the ed of Jinghua Daguan, more than 3000 yuan, and Yingtian's ed ed is also OK, more than 5000.

It is recommended that you buy Yingtian's 60ed. Totally enough for your situation.

If you ask for it, it's good to use a good viewing glass, it is recommended to buy a small black cannon, this is not an ED lens, if it is an ED lens, it will be very high, and there is no need for such a high requirement for the ground observation of the flower: achromatic full-surface multi-layer broadband film high-sharpness refraction.

1.If you look at the stars, they are only slightly brighter than what you can see with the naked eye, and they have no characteristics. If you look at the planets, Venus and Mercury (which are usually invisible) have waxing and waning, Saturn's rings, and Jupiter's four Galilean moons.

Then there are some nebulae or star clusters, it depends on the actual situation.

2.The price of a telescope for ordinary astronomy enthusiasts is less than 1,000 yuan, and of course, the price is directly proportional to the performance. I suggest that the landlord buy a refracting telescope with an aperture of 80mm, with a focal length of more than 750mm, and the price can be 600 to 900 yuan.

These are a little bit of parameters, at the discretion of the landlord to consider)

3.First of all, all kinds of telescopes have their performance, not everything can be seen, **meteor shower, the most ideal instrument is our eyes!

Because the eye has the largest field of vision, you can see meteors flying out of the sky. But no telescope can compare to the field of vision of our eyes. The landlord wants to see the meteor clearly, but the magnification of the telescope comes at the expense of the field of view.

If you think about it, the popularity came very quickly, and if you wait for it to come and then chase it with a telescope, it will be too late. If you want to wait for the rabbit, I am afraid that you will not be able to wait for a meteor to break into the telescope's field of vision in one night. So, the naked eye, binoculars, astronomical telescopes, they all have their own uses.

What I'm talking about is my experience as an astronomy enthusiast and common sense. If the landlord doesn't believe it, you can try it yourself, hehe.

If you have any questions, you can ask them again.

I don't know what the specific parameters of the landlord's telescope are. The effectiveness of an astronomical telescope is mainly determined by the aperture of the objective lens, and the larger the aperture, the darker the celestial objects and the more detail they can see, and the greater the limit magnification they can bear. It is certain that the astronomical telescope can only see the point of light when looking at the star, let alone yours, and it is impossible for them to see the circle surface of the Keck, very large, and Pleiades star clusters.

Because the stars are too far away and the volume is not large, they belong to point light sources.

There is no problem with the 70mm aperture to see the waxing and waning of Mercury and Venus, the polar crown of Mars, the cloud belts of Jupiter, the rings of Saturn, and Uranus and Neptune. But Venus has a dense atmosphere on its surface, and there are no telescopes on Earth that can see the surface of Venus; Mars has strong storms, and the red surface seen is iron-bearing dust; If the observation conditions are good and the operation is skillful, the 13 cloud bands on the surface of Jupiter can be seen; Saturn's rings have been facing us sideways for a few years, making it difficult to observe, but now the situation is gradually improving, and 2014 is more suitable for observation; Uranus and Neptune are so small and so far apart that they can only see a bright spot, and Uranus can barely make out the circle at opposition.

This caliber can theoretically see all 110 Messier deep-sky objects, but due to various problems such as operational problems, environment, and the level of observers, it is very good for novices to see more than a dozen Messier objects. In the case of nebulae, you can only see the Large Magellanic Nebula and the Andromeda M31 Nebula (in fact, they are all galaxies), the Orion Nebula M42, the Taurus Pleiades M45, and the Cancer Ghost Cluster M44. If you can use it in the wild without any light interference, you will see more things, such as the Nebula M8 and M20 in Sagittarius, and the globular cluster M13 in Hercules.

But it's mostly a blurry white spot.

There are a lot of clear celestial maps that can be seen on the Internet, but many of them are post-processed by software, and most of the ** on the Internet are taken with relatively strong telescopes, and the effect of human eyes is different from that of CCD for a long time** after all. One reason you don't see a nebula cluster may be due to the environmental constraints of your viewing location, as these objects are usually not very bright and easily obscured by light pollution. Second, it may be that you are not familiar with the sky and do not know the location of celestial bodies.

That's right. I think it's good to use an astronomical telescope here:

Moon craters, Venus waxing and waning, Saturn's rings, Jupiter "Wood Grain" and 4 Galilean moons. Even if it's just to see this, I think it's worth it to buy an astronomical telescope.

Stars look almost exactly the same in a telescope as they look to the naked eye, just a bright spot. Of course, in theory, it should be a little brighter. But it doesn't feel obvious. Some binary stars that appear to be one star to the naked eye can be separated in a telescope.

Some nebulae (such as the Great Andromeda Nebula) should theoretically also be visible. And it has a visual shape. But it's very hard to find. You can't see it with the naked eye, you can't see it in the finderscope, and you have to look at the star map to find what is difficult to find.

You can get a good price for this price. Personally, I recommend you Xingtran 80EQ

Now it's about 600 yuan. Last year, it was more than a thousand! The price is all because of.

The 80EQ has become an entry-level model for astronomy enthusiasts and has a high market volume. Since this year, Cintron has put down its value in the domestic market to participate in low-price competition. It can be said that the price-performance ratio is unbeatable.

Even in miscellaneous astronomical telescopes, it is difficult to find 80mm aperture with equatorial mount, which sells only 600. What's more, Xingtron is the world's most famous astronomical telescope brand. The American Astronomical Society's event was put on the White House lawn to show Obama the Cintron.

With an ordinary astronomical telescope, it looks like 4 large planets – Venus, Mars, Jupiter and Saturn.

I think the most interesting thing is to look at the profit and loss of Venus, the 4 moons of Jupiter (Galileo's moons), and the rings of Saturn.

Looking at the stars will surely disappoint you. It's no different from the naked eye. Slightly brighter.

The telescope of the average astronomy enthusiast can be seen for 100 yuan. Of course, if you have more money, you can have a better effect if you are more expensive. However, I personally feel that the refractive type of amateur astronomical telescope is better than the reflective type.

A: No, you can't. You'll know if you've seen it. Aiming at a star with an astronomical telescope is not an easy task. The meteor is so fast that it's gone before you can turn the barrel.
