First of all, telescopes can be divided into handheld and desktop high magnification. The hand-held one can be carried with you, and you can see it by holding it, and the desktop one must be on a tripod and cannot be observed by hand. Because if you hold it, the multiplier is too high, and you can't see it at all.
If it is handheld, whether it is a civilian or military telescope, the multiples of the handheld have a standard optimal multiples range, that is, 7 10 times, of which the most commonly used in the military are 7 times and 8 times. The so-called 20 times, 30 times, 50 times, and so on are all deceptive, not even regular products. People who don't understand are easily deceived.
And if it is a tabletop type, this multiplier range is relatively large because there is a tripod. But for the observation of the scenery on the ground, generally the highest and the highest, my experience, when looking at the scenery on the ground, more than 35 times the image quality begins to drop significantly, because the air begins to boil, and 60 times the beginning, there is no meaning. Now there are many counterfeit and inferior products, accounting for more than 95% of the market, as well as false propaganda, such as "night vision", "infrared", "Japanese cherry blossoms", "Russia" and so on, etc., it is recommended that you understand the basics:
You can take a look.
Particular attention is paid to the issues related to multiples, military, night vision, etc., that is, the introduction of some common false propaganda. If you don't know this, then it is recommended to know more, and when you are sure, you can take action, there are many people who are deceived by this. Because there are too many fake and inferior products, and such products have a characteristic, they like to use "high times" to deceive people.
If you know this, then talk about it in detail, in fact, what multiple to choose, and your use is very related, for example, if you go to the sea to use, use it on the ship, because the shaking is large, you have to choose 7 times, if you only use it at home, then any multiple can be, if you are traveling, then it is recommended to choose 8 times, the multiple is moderate, and the field of vision is also large.

Astronomical telescope of maximum magnification.

7 times between 10 times.
Small hand-held telescopes for personal use should not use too large magnification, generally 3 12 times is appropriate, when the magnification is too large, the imaging clarity will deteriorate, and the shaking is serious, and the telescope of more than 12 times is generally fixed by means such as tripods.

Answer: The general telescope needs 10 times, and the magnification is generally divided into three grades, the medium magnification is 6 to 10 times, the large magnification is 10 to 20 times, the magnification is 20 to 40 times that of the German style, and the magnification is 25 to 40 times that of the domestic one. 2/4
Telescopes are not always better if they are larger than 10x, and if they are more than 10x, they should usually be mounted on a tripod. 3/4
The larger the aperture, the greater the field of view, the greater the brightness, which is conducive to observation in low light, and can generally be selected between 30 and 50mm according to the need. 4/4
Most of the ordinary telescopes on the market use plastic mirror bodies and lens barrels, and only a few high-end products use all-metal structures, which are expensive but durable.
I hope you will adopt it.

The higher the magnification of the telescope, the clearer it is. In fact, the clarity of a telescope is determined by a combination of factors. First of all, the telescope's effective aperture is a key factor in this process, which refers to the maximum diameter of the beam of light through the telescope's optical elements, such as lenses or mirrors.
In addition, the magnification of the telescope is also related to clarity. Higher magnifications can provide higher magnification, but some of the clarity of the image may be lost. In telescopes with higher magnifications, the optical elements through which the light passes may be relatively smaller, so the image may be darker and more blurry.
It also depends on the quality of the telescope. Higher quality telescopes are able to maintain clarity at high magnifications, while lower quality telescopes may also lack resolution at relatively low magnifications. In addition, the design of the telescope can also affect its clarity, for example by utilizing lens materials that reduce image dispersion.
Therefore, the clearest telescope is not just to look at the multiplier, but to consider a combination of factors. In clear weather conditions, the use of a 10x telescope is clear enough. However, in low-light conditions or where higher resolution is required, a larger-aperture, higher-quality telescope needs to be selected and moderately multiplied.
Finally, when using a telescope, you should always pay attention to the cleaning of the mirror surface to ensure the clarity of the image. <>

The choice of telescope magnification depends on the use case, generally speaking, higher magnifications can obtain a more Jane's distance and a clearer image, but at the same time, a larger lens and a higher ** are also required. Therefore, the optimal choice of telescope magnification needs to be judged according to actual needs.
For example, if you're looking at birds or observing celestial objects, a high-powered telescope will allow you to see these objects more clearly, resulting in better visuals. If you need to look at objects farther away, smaller and more detailed, then a high-magnification lens will be more suitable. And if you only need to observe a more ordinary scene, a low or medium magnification lens may be more suitable.
For astronomy enthusiasts, it is common to choose a high-powered telescope of more than 30 times, which can obtain more detailed observation quality and clearer vision. For bird watchers, a 20x to 40x medium- to high-power telescope may be more suitable, sufficient to observe a miniature of objects at a relatively long distance.
Of course, the optimal choice of multiples has a lot to do with the manufacturer, type and lens holder part of the telescope, so when purchasing, you should pay attention to the size and weight, check the quality, and see if the function is more in line with your actual needs, so as to better realize your own Yuyu observation needs. <>

6-10 times.
The ideal telescope should magnify the target losslessly, and truly restore the details, many users feel that the magnification of the telescope should be as large as possible, in fact, the magnification of the telescope is determined by many factors, each telescope is marked with the main parameters, such as 7x35 means that the mirror is 7x, and the objective lens diameter is 35mm. Generally, less than 6 times is a low magnification, 6-10 times is a medium magnification, and more than 10 times is a high magnification. Now the main discussion is about the magnification of binoculars.
However, it has been proven that the most suitable telescope for handheld observation should be 6-10x magnification.
The telescope is used to pay attention to the rough items.
Never use a telescope to look directly at the sun, as strong sunlight can cause great damage to the eyes.
Users who wear glasses are advised to turn down the goggles of the telescope before making observations when using the telescope, so that they can see the full field of view.
Although many telescopes are now waterproof, try not to throw the telescope into the water in order to try such a function, the telescope is a precision instrument, and you should never slam the telescope, put pressure on it, or do other strenuous movements.

The angular diameter of the area of the sky that can be well imaged by the telescope is called the field of view of the telescope or the angle of view of the field of view ( ) The field of view of a telescope is often determined at the time of design. The field of view of a telescope is inversely proportional to magnification, and the greater the magnification, the smaller the field of view. Different optical systems, different imaging qualities (due to aberrations), different apertures, and different focal lengths determine the size of the telescope's different fields of view (in the case of astrophotography, the size of the negatives or CCDs also constrains the size of the field of view). >>>More
One day in the early 17th century, Hans Lippershey, the owner of an optical shop in a small Dutch town, in order to check the quality of the polished lens, arranged a convex lens and a concave mirror in a line, looked through the lens, and found that the church spire in the distance seemed to be getting bigger and closer, so he accidentally discovered the secret of the telescope. In 1608 he patented a telescope he had made, and in compliance with the authorities' request, he built a binocular. It is said that dozens of opticians in the town claim to have invented the telescope, although it is generally believed that Lieberch was the inventor of the telescope.
The cheapest one is probably the one with a diameter of only 50mm. The kind of people can only see the stars that can be seen with the naked eye, and as for the ones that can see clearly, only the moon. As for the rings, Saturn's rings can be seen dimly (the rings need to be facing the Earth, and they can't be seen even if they are tilted to a certain extent.) >>>More
