Audiophile level astronomy is the same as good progress, and the problem of equipment purchase. Rook

After reading the landlord's records, it can be seen that the landlord has a certain basic understanding of astronomy, and I hope the landlord can join our team. But it can also be heard from the tone of the landlord that the landlord is still relatively young and a little sharp. Of course, this is also understandable, a young person is useless if he is not arrogant.

But please also pay a little attention to the landlord and put away his edge, after all, there is a sky outside the sky, right? And when you come here to ask questions, how would you feel when you want to speak to the teacher in such a tone?

The landlord has already given the aperture of the telescope, 50mm, and the corresponding limit magnitude can be calculated - etc. What is the concept, hundreds of thousands of stars, dozens of pairs of binary stars, all Messier objects, hundreds of deep-sky objects, eight planets, a number of moons.

In terms of aperture and magnification, it is suitable for astronomical observations, but it is better to have a tripod.

To have a higher parameter of binoculars also means a higher **, the aperture of the telescope is closely related to the aperture, if you want a larger aperture, silver is also certain.

If the landlord thinks that the space for his astronomical development is too small, I would like to give the landlord a recommendation and suggest that you work hard in the direction of the National Astronomical Olympiad. Competitions allow you to prove your astronomical prowess and meet more like-minded people (which are not my forte, but I know a lot of people who are very professional in this area). As for the information to believe, you can refer to the forum of the Beijing Planetarium - Astronomy**.

It's a hassle to look at the budget...

I heard from a friend that it costs a lot of money to build a good equatorial mount, the kind that can automatically guide stars.

Not to mention the shelves or something, there are more than a million burners.

What a frozen CCD, even more burning.

The entry-level is the reentry mirror, which is cheap and easy to use, and the kind that can be changed for eyepieces.

This topic should not be asked, you should go to the forum that specializes in burning astronomical telescopes, and there should be a master in the forum of the burner who is unscrupulous.

I've seen a forum dedicated to burning astronomical mirrors before, but I forgot the address, so you can search for it yourself.

Stellarium is of course the first choice for astronomy enthusiasts, and this one is the green version, which filters out a lot of useless files.

Asynx PlanetArium is an astronomy education software that contains information on more than 2,500 stars and also provides real-time positions of planets. Here's a closer look, but I think it's a bit of an exaggeration, so be careful.

Asynx Planetarium is a free astronomy education app that contains detailed information about up to 2500 stars, complete data on nine planets (currently eight planets), and 88 constellations. It also allows friends who want to get a glimpse of the mystery of the stars to know the appropriate observation time.

There is also a Chinese version.。

Three-dimensional star map Oh, the Chinese's own astronomical software, support it.

The Stereo Star Atlas software is designed to help ordinary astronomy enthusiasts increase their knowledge and interest in astronomy. Through this software, astronomy enthusiasts can understand the starry sky more intuitively and understand the operation laws of various stars.

skymap I'll give you a Chinese version:

I personally recommend skymap and stellarium, the first software is more convenient to query, and it is particularly small, but the latter software is very powerful, the starry sky is more real, and it has a strong complementarity to skymap when simulating solar and lunar eclipses.

My computer is also 256M.,There is no problem with the above two software.。

Of course, I don't rule out other better software, but I personally think that these two are more than enough.

If you have better astronomy software, I hope you can put it up and share it with you.

Find a super good software to simulate the starry sky, everyone hurry up.

The software is not big, but it is very useful.

The demo version of Skymap is only a few tens of MB and the installation is also very simple.

Do you have to take an exam before making friends?

I know that the red shift and blue shift pulse are these, whether the universe was founded by the big ** is still difficult to say, no one can come up with real evidence, although the scientific community always says to find evidence. But no one has really seen it, right, believe in the truth. (Hehe, equal to nonsense.)

I also like astronomy, but now I don't have time to pay attention to these things because of the pressure of studying, and I don't remember much, so that's it.

The last question, the first reaction is"5"Right, I liked this number since I was a child.

First of all, I am not a believer in the grand theory of the universe, and I am inclined to believe that the universe has remained basically the same since the beginning. Matter in the universe is transformed by energy. The existence of energy in the universe is unbalanced, and secondly, I believe that space is multidimensional, and at a very small scale, space is extremely compressed, and people cannot feel it.

Just as an ant crawling on a curled piece of paper can only climb from point A to point B (points A and B are the two corners of a piece of paper, and due to the curvature, the two corners are very close to each other), while a human finger can go straight from point A to point B. The universe is also multiple. There are an infinite number of identical, or similar, or completely different universes.

Personally, I think that human beings can only perceive, but cannot detect, let alone reach another universe. Of course, I'm not saying that there is another Earth, another me, and I personally disagree with this view, again, speed can be faster than light, and time can be reversed. Of course, I can't think of whether the objects on Earth can withstand this situation and go back to the past.

But the individual does not agree with the cycle theory.

Astronomy is also divided into many types, I don't know much about observational astronomy and aeronautical astronomy, I know a little about cosmic astronomy, my main hobby is astrophysics, especially theoretical astrophysics, I read a lot of books, mainly Hawking's. I also read some books on modern physical theories, such as M theory, membrane theory, ten-dimensional and eleven-dimensional theory, and so on. Classical relativity and quantum mechanics are also seen a lot.

Upstairs inexplicably ......

Upstairs upstairs is pretty ......

I think it's just a cycle, just like saying that people today were born by a mother 137 years ago at the latest, I think it's just a cycle, and now scientists don't think that black holes are actually white holes? This may lead to the possibility that the birth and death of matter in the universe are constantly making a big cycle, what do you think?

An asteroid hits the Earth.

You dare to post the answer.

It seems that few people can see the question here, right?

You can go to a dedicated astronomical forum and ask.

Currently the largest forum for astronomy enthusiasts in China:

Shepherd Astronomy Forum.

In addition, the Qingdao Astronomy Enthusiasts Association is quite active, I don't know if they have Tai'an people there.

You can get in touch, they also have a special section on the shepherd.

Ah, can I?

I like it too!!

I like to listen to the stories of the constellations, see all kinds of different universes**, and I am super interested in solar and lunar eclipses but can never explain them clearly.

And the origin of the earth and so on and so forthFind Beidou in the summer sky.

Those stars will give people a lot of reverie.

HeheHow to add you?

I'm also a rookie, what should I do?!

The solar eclipse is super complicated and I can't tell you clearly.

A solar eclipse is simply said to be formed by the moon blocking the day's rays.

The regions that see the total solar eclipse are in the umbra, and the partial eclipse is in the penumbra, and I think they may not have the same time.

In the case of a total solar eclipse, it should be determined by the distance between the Earth and the Moon, the distance between the Sun and the Earth, the revolution of the Moon, the rotation of the Earth, and the speed of the Earth's revolution.

The distance between the moon and the sun can be calculated from the apparent diameter of the sun and the moon The yellow and white channels refer to the orbit of the sun and the moon in the celestial sphere, and the equator is the celestial equator that has the illusion of the earth's equator extending to the celestial sphere.

The distance determines the size of the shadow.

The angle of intersection determines the speed at which the shadow moves on the ground (also affected by the speed of revolution, which is assumed to be constant here) The shadow movement path.

The eclipse time is the time from when a person enters the shadow to when he leaves the shadow.

So the bigger the shadow, the slower the shadow moves, and the longer the eclipse lasts.

This seems to be more complicated, but it simply means that the shadow is required to be cast on the Earth, and the distance and the angle of the celestial bodies have an effect on it, and it's about the same reason as above.

The main factors that determine the size of the food limit:

1. That is, the intersection of the white path and the ecliptic;

2. The apparent radius of the Sun and the Moon;

The latter two in turn depend on the distance between the Sun and the Earth and the distance between the Moon and the Earth at that time.

There are more intuitive explanations in the geography textbook for the first year of high school, as well as illustrations, so you might as well check them out. In addition, you understand what is the yellow and red angles, what is the umbra, what is the penumbra and so on.

cold

I believe that the truth is always in the hands of a few.

According to Stephen Hawking's cosmic large**, the universe is constantly expanding, and the temperature will get lower and lower, when the universe belongs to an atom, the temperature is like hundreds of millions of degrees, so it will be far away, am I right? Big brother, don't keep taking this kind of low-level problem out in the future, we astronomy hobbies are not easy to bully, always support Hawking, Hawking first.

eeeeeeeee

There is such a thing in the world

None of ...... faster

hot,hot.Because cold is frozen, how can it be fast?
