What is it like to look at the sun through a telescope?

Telescopes see the sun in a variety of ways, all of which focus on reducing the damage of sunlight, because telescopes will gather more sunlight than the naked eye, and the naked eye can still make many people unbearable to look directly at the sun, think about how much damage can be caused by receiving at least thousands of times more sunlight.

Without Bard membrane, it can be observed in the early morning or evening in winter, when the sun is red and not dazzling, the telescope is fine, the sunspot can be observed with the naked eye, you can also use X-rays, at least the four layers of the blackest, cover the telescope inlet, the telescope should also use a light shield, further reduce the amount of light, so that it is okay to see the sun at noon, once observed the solar eclipse, do not cover the eyepiece, it will catch fire.

The equipment that I used to see the sun for the first time was the Xinglunte 80EQ solar filter and the gabard membrane were all used As a result, I didn't see a big circle of the sky (about three or four o'clock in the afternoon in autumn), and then I used the sun filter directly, and I saw it, and it was not brighter, and then I always used only the sun filter.

To see the sun with a telescope, you must use Bard membrane, you must use Bard membrane, you must use Bard membrane. Important things are said three times, of course, if it is projected with a telescope, there is no need. Looking at sunspots, you can look at the number of sunspots on the day and decide whether to set up a mirror or not, after all, setting up a mirror is still a very physically demanding thing.

That's the experience. There are no details to speak of, but you can see sunspots, 80eq, which are slightly larger than the Earth.

In addition to the Bard membrane, you can also use the Herschel prism and the solar telescope for astronomy enthusiasts, but it costs a few thousand and is very expensive, but you can see the solar chromosphere, etc., which is spectacular.

You can see it. In 2011, when sunspots erupted, two large sunspots were observed using ordinary binoculars. Usually, the observation depends on the magnification of the telescope.

One day, I was observing the sun with 80EQ, and my eyes were manually looking for the eyepiece, and I suddenly remembered that I forgot to install Bard membrane on the end of the objective lens, and then removed the eyepiece and found that the plastic of the inner ring had melted away.

When I was in high school, I didn't have Bard film to read it on discarded film, but then my right eye was directly astigmatized, and my vision was much worse in my left eye, which is quite light.

If I want to go to the sun, my eyes will hurt so much, so I don't recommend you to do so.

The most inconclusive thing in this world is the sun, and you have added a telescope, do you dislike your two eyes?

Introduction: The first function of a telescope is to magnify the opening angles of distant objects, allowing the human eye to see details at a small angular distance. The second function of the telescope is that the beam collected by the objective lens is much thicker than the pupil diameter (up to 8 mm) and is sent to the human eye so that the observer can see faint objects that were previously invisible.

So, why can telescopes see so far?

The convex lens with a large diameter and long focal length in front of the telescope is called an objective lens; The lens with a small diameter and short focal length at the back is called an eyepiece. The objective lens concentrates light from distant objects behind you into an inverted, zoomed-out image, which is equivalent to moving distant objects to the image at once. The inverted image of this scene falls right on the front focus of the eyepiece, so looking at the eyepiece is like looking at something with a magnifying glass, and you can see a virtual image that has been magnified many times.

In this way, in the telescope of **, the distant scenery looks like it is close at hand. Like other optical instruments, telescopes of various structures have been developed one after another after a long history. According to the principle of optics, it can be divided into two categories:

Refraction and reflection.

Telescopes, commonly known as prism binoculars, are often used in military and field surveys because of their short barrel, wide field of view, and easy portability. Reflecting telescopes use concave mirrors as objective lenses and convex lenses as eyepieces to observe celestial objects at the observatory. The first person to patent a telescope was Hans Lipperch, a Dutch manufacturer of optical instruments, who applied for a patent in 1608.

According to the Lipper Hope Telescope, the Italian scientist Galileo made one himself in 1609. The 00-300 was improved in design and was soon used to study planets and stars.

As long as there are infinite objects, the telescope can see the infinite. At a distance of several hundred light years from the planet, we can see without a telescope, but with a telescope. The moon is far away from us (380,000 km), but we can see it with binoculars.

Because the telescope uses the principle of concave-convex mirrors, it is possible to see that far.

Because through the principle of the telescope, the telescope can see things far away, and the telescope can see the stars in the sky.

1. Do not use the telescope directly **sun,**the sun must pass the projection method or have special filtering measures;

2 Don't treat telescopes as toys, telescopes are precision optical instruments that should be used and maintained carefully.

3 Don't think that you can see everything with a telescope, you can indeed see the details of celestial bodies and celestial bodies that cannot be distinguished by the naked eye through a telescope, but the better the effect, the higher the one, there is no perfect telescope, the most important thing is to choose the one that suits you;

4 For every telescope, there is a suitable magnification. Exceeding this multiple does not enhance the ability to distinguish, but rather makes the object very dark and difficult to see. With a telescope of 60 80 caliber, the appropriate magnification should be less than 100x, and with a magnification of 200x, almost nothing can be seen.

5 If you can't identify more than five constellations in the night sky, don't rush to use a telescope, because you can't find observable stars, you can only look at the moon;

6 Astronomical telescopes can also often be landscaped or flora and fauna, and can easily obtain higher magnifications than binoculars. However, the magnification should be less than 100 times, and 20-50 times is the most appropriate.

Because the sun's rays are very strong, they can do a lot of damage to the glasses. If we look directly at the sun with a telescope, the light will focus on the eyes, causing damage to the retina and pupils.

Because the brightness of the sun is unbearable for the eyes. First, it burns your eyes because the sun is too hot. Second, it can cause a fire, because focusing can cause a fire. Thirdly, it can damage the body. Because the sun's rays have radiation.

Because the eyes can't stand the sun's bright light. The distance between the earth and the sun is very far, and the light that the sun shines on the earth has weakened a lot, and people are not likely to be able to look directly at the sun, let alone look at it with a telescope, and the line of sight does not know how many times it has been narrowed.

Because it is easy to focus light when looking directly at the sun with a telescope, it produces a very high temperature, and the high temperature will instantly burn people's eyes, which will directly lead to blindness and have very serious consequences.

The telescope is made by a combination of multiple magnifying glasses, and if the sun will bring a burning sensation to the eyes, it may burn the eyes and bring harm to the eyes if it is serious.

Because the telescope can concentrate the sunlight to a point, as we all know, the sun is very hot, and if the sunlight is concentrated, if people use their eyes directly, it may cause blindness, and if the object is irradiated, it may cause spontaneous combustion of the object.

Because the telescope has the function of concentrating light, if you look at the sun, it will gather light and heat to a little bit and hurt the eyes, so it cannot be used to look at the sun. It is very harmful to the eyes, ranging from blindness to burn the eyes and cause blindness.

Because the telescope will focus the sun's rays at one point, it will produce thousands of degrees of heat, burning the eyes and even leading to blindness.

It is very dangerous for a telescope to look at the sun without any protection. The strong sunlight will be focused through the telescope, which will produce a high temperature of thousands of degrees, and a piece of white paper will burn instantly under the telescope, not to mention the fragile eyes of people?

Because looking at the sun with a telescope can easily focus the light, which can burn people's eyes, and the high temperature will instantly damage people's eyes.

The best way to see the moon is to use an astronomical telescope. The astronomical telescope itself is designed to observe celestial bodies, and the general astronomical telescope can see the circumferential mountains on the moon, while the better ones may be able to see the surface of the moon clearly, and some can even see the potted surface on the surface of the moon. The above is the answer to Guan Wangyu's question "What telescope to use to see the moon", and the next is the supplementary content of the astronomical telescope, interested viewers are welcome to continue**.

1. Introduction of telescopes: The world's first telescope was invented by Galileo in 1609, and in the subsequent human development, telescopes are also developing, and astronomical telescopes are a part of the development branch of telescopes.

2. Introduction of astronomical telescopes: astronomical telescopes are currently one of the most effective observation tools used to observe celestial bodies, and some relatively large astronomical telescopes can even see celestial bodies far away from the earth.

3. The importance of astronomical telescopes: Astronomical telescopes allow people to more conveniently and intuitively observe celestial bodies very far away from human beings, and this has also made great contributions to human aviation.

4. Placement of astronomical telescopes: Since the development of some astronomical telescopes, in order to be able to observe celestial bodies more intuitively, people have even sent astronomical telescopes into space, so that people can directly use astronomical telescopes to observe celestial bodies in space.
