Anonymous users2024-02-10The people upstairs can talk nonsense! Do you really love astronomy? Do you really delve into astronomy? Do you really have astronomical telescopes?
Let me tell you about it @! I have made a lot of astronomical telescopes of different magnifications! Knowledgeable about observation telescopes of all magnifications!
Twenty-five times the craters and volcanoes of the moon can be seen absolutely! Some downstairs say that it is seen when the moon is full, which is also nonsense! When the moon is full, you can only see a little because of the light!
If you want to see the main building, you should see the crater the most in the middle moon or so! Generally, craters are concentrated in the middle of the half-moon where light and dark meet! I'm not saying nowhere else!
Just to say, if we use the telescope directly, we can't see it because the light is too bright and reflective, etc. It doesn't mean nothing! Someone downstairs said yes, with binoculars we can also see a few craters, if you study to see!
For us amateur astronomers! Generally, using 50 multiples is very suitable, and your telescope can't be too bad! The multiplier can be a little smaller, but the optical glass must not be bad!
May I ask the landlord what kind of telescope is yours?? Is it really 25 times? By what you said I don't think yours is an astronomical telescope in general, I'm a little skeptical of what you're talking about!
Don't see that your telescope says 25 times just say 25 times! The telescopes of small manufacturers are all false multiples! Their telescopes are generally within ten times!
But the multiples are very high, such as: 25*30, this is all a lie! I have a method for measuring the magnification of a telescope, you can try it!
You draw an equal row of squares from a blank piece of paper, a little smaller, put it about seven or eight meters away, and look at the square in front of you through the telescope with one eye (after it is clear) and the other eye does not look at the square in front of you through the telescope, and you count, for example, you find that a square under the telescope is as big as the side length of 10 squares without the telescope, and the telescope is ten times larger!
Also, if you hold a telescope and look at the moon, your hands will tremble a lot! Can't see clearly! It's best to lean it against a wall!
Does the landlord love astronomy? If you love it, buy an astronomical telescope! It's only more than 100 yuan on **, you can search and see it when you have time! It is a very good choice for beginner astronomy enthusiasts!
Good luck!

Anonymous users2024-02-09I also found that someone is talking nonsense, under normal circumstances, it does not need 25 times, a 7*50 binoculars can observe the crater of the moon, but the resolution is not high enough, only the large crater can be distinguished, and the small one cannot be seen clearly. 25 times can already clearly observe most of the craters on the moon (this is a premise, that is, the objective lens of your telescope should not be too rubbish, and the chromatic aberration should not be too large, otherwise the observation effect will be extremely poor).

Anonymous users2024-02-08The weather is good, the place is good, the time is good, and you can tell it with the naked eye! I have two mirrors, one binocular, one 90090 astronomical. **The best magnification (effective magnification) of the moon is 40 to 80 times in my personal opinion; My astronomical scope is tripled, doubled, and equipped with the smallest eyepiece, with a maximum of more than 300 times, but the moon is not clear, and the image is too dark; So because of [Mirror]!

Anonymous users2024-02-07There are shaded parts on it, and if the weather is good, you should be able to see some craters, but it's very vague. It is best to see it on the fifteenth and sixteenth day of the lunar calendar.

Anonymous users2024-02-06I can't see it at all, I can't even see the crater, at least 70 times more.

Anonymous users2024-02-05What you can't see can only be seen at least 200 times more.

Anonymous users2024-02-04With a 50mm telescope, you can see a crater with a diameter of one kilometer.
With a 60mm telescope, you can see a crater with a diameter of one kilometer.
With a 70mm telescope, you can see a crater with a diameter of 1,000 kilometers.
With an 80mm telescope, you can see a crater with a diameter of one kilometer.
With the naked eye, you can see a kilometer-diameter crater (adapted to the dark)** high, if you have enough money, you can consider buying one.
Amateur astronomers generally control the multiples of mirrors within 200 times, and less than 100 times to see the moon. The landlord said that 500 times is too general, can you be specific. Almost 70 times you can see Jupiter's extreme moons, Saturn's rings.
Hello Beginners mostly choose refraction and maca reflection is not recommended to use Sky Wolf Sailing, Xingtron 80eq, Boguan 80, Boguan Marca, Xinda 80, Xinda Marca are all great Beginners are very practical! I've been playing with equipment for a long time, and it's been one step at a time, and my first astronomical telescope was the Changge of the Celestial Wolf.
The pole is an equatorial mount.
Buy an 80eq 80eq parameter: >>>More
**Proportional to the square of the aperture (i.e., the area of the primary mirror). If you have money, you can see details such as the spiral arm of the extragalactic galaxy with an aperture of more than 200mm, and a spot of light below 200mm. The same is true for nebulae, the stars are one point anyway, even with Hubble, but large aperture can distinguish more binary stars, polyconjunctions. >>>More
