What does 1200 30 mean on a telescope

Hello, I'm afraid it's a bit of a pity, this product is not a regular product, the above parameters are not regular, 1200 30, literally 1200 times, the caliber is 30 mm, it must be untrue, because such unreasonable parameters of the handheld military telescope will not exist at all, at most 10 mouths.

Now there are many fake or inferior products on the market, almost accounting for more than 90%, including false propaganda, and random parameters, such as 9999*50, "cherry blossoms" and "night vision" If you don't understand, you will basically be fooled.

You can take a look.

Common Sense and Discernment".

The main thing is to see how to discern it, as well as some of the common false claims. It includes an introduction to multiples, military telescopes, etc.

But also comfort, don't be too sad, there are too many fake and inferior products now, and there are too many fools! Therefore, the landlord is not the first 100,000, nor will it be the last 100,000

It is a problem of the market quality supervision department.

It consists of 2 convex lenses, and the two digits are the magnification of the objective lens and the sight lens.

is the size of the telescope, 20 is the multiple, and 100 is the objective diameter of the telescope.

Magnification. The magnification calculation method of the telescope: objective focal length Eyepiece focal length, for example:

The 102 1000 telescope has a primary lens focal length of 1000mm (mm), and when a 10mm (mm) focal length eyepiece is used, its magnification is 1000 10 = 100 times.

Extenders. Extender (Barlow or Barrow): The focal length of the objective lens can be extended by two times (2x) or three times (3x) or more, and the combined magnification of the telescope after the extender is the focal length of the objective eyepiece focal length x the multiplier of the extender.

Telescope Maintenance:

1. Ensure that the telescope is stored in a ventilated, dry and clean place to prevent mildew.

2. The remaining dirty spots or stains on the lens should be gently wiped with a professional lens cloth to avoid scratching the mirror, if you need to clean the mirror, you should use absorbent cotton to occupy a little alcohol, wipe from the center of the mirror along a direction to the edge of the mirror, and constantly replace the absorbent cotton ball until it is wiped clean.

3. The telescope is a precision instrument, and it is important not to fall, press or do other strenuous actions on the telescope.

The number in front is the magnification, and the number in the back is the caliber.

That is, 100*25 means that the object is magnified 100 times and the diameter is 25mm.

Although the principle of the telescope is relatively simple, it brings us a high-tech feeling, and now it has also played a basic popularity, a large number of people can come into contact with the telescope, the world inside is so unreal, things beyond 100 meters can be clearly seen, because of this, we should not use the telescope to look around, should be positive and positive, of course, we also have to protect their privacy, the telescope can be seen, criminals must have something else to see, Hope mine can give some help.

100x100 is the size of the telescope, 100 is the multiple of the telescope, and 100 is the objective diameter of the telescope.

These are the two most important parameters of a telescope, and when buying a telescope, you should observe these two values and choose the right telescope for you. If it is a telescope within 10 times, you should choose a larger aperture, which looks more comfortable and has better stability.

The magnification of the telescope is divided into three grades, the medium magnification is 6 10 times, the large magnification is 10 20 times, and the magnification is 20 40 times in the German style. Generally domestic is 25 40 times. Telescopes do not have a larger magnification as much as possible, and if the magnification is more than 10x, it is usually necessary to choose a larger aperture.

The purpose of telescopes is different, and the performance is also different, and the performance of telescopes is generally divided into monoculars, astronomical telescopes, high-power telescopes, binoculars, ranging telescopes, bird watching telescopes, etc. According to the classification of uses, there are forest fire prevention telescopes, electric power patrol telescopes, outdoor tourism viewing telescopes, sports competition concert telescopes, etc.

Each type of telescope is different, before buying, you have to think about what to use it for, if it is just a simple ** concert, you can buy a concert telescope, this kind of telescope is specifically for watching concerts.

qiezi9221 nonsense! That's a microscope! The annotation on your telescope:

100m 1000m, which means that you can see a range of 100m wide when you look 1000m away with a telescope, as for the magnification, there is no information available in your message to determine.

26x magnification and 50mm caliber meaning.

26 represents magnification, for example, if something is at 2600 meters, looking at it with a telescope of 26x is equivalent to looking at it at 100 meters. 50 is the diameter of the objective lens of the telescope, also called the aperture. The larger the aperture, the more rays will be collected, and the target will appear brighter at the same magnification, but the telescope will also be larger.

A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. It uses light rays that pass through a lens to refract or light rays to be concave mirrors.

The reflection causes it to enter the small hole and converge for imaging, and then it is seen through a magnifying eyepiece, also known as a "clairvoyant".

The choice of Wangsheng telescope: what kind of telescope to choose depends on what you want to see with it, if the potato is to play in the mountains and rivers to see the scenery, usually watch performances or competitions, it is recommended to choose 8x30 or 6x30, the magnification is enough, and it is relatively light and easy to bring. To see the starry sky, it is recommended to be 10*50 or 7*50, with a large aperture, and you can see relatively faint stars.

To check the line and check the things in the high places, you can choose 12x x50, and put it large, so it is easy to see the problem.

The field of view is 1000 meters, and the magnification is 20 times.

When people buy a telescope, it is common to see several Arabic numerals on their price list.

Let me give you an example. For example, it is marked with 10 50 mm 5°, which means that it has a diameter of 50 mm and a field of view of 5 degrees (i.e. at 1000). Some people may think that the higher the number of technical parameters, the better, but this is not the case.

The magnification is inversely proportional to the width of the field of view, i.e., the greater the magnification, the smaller the width of the field of view, which is not conducive to searching. The larger the diameter of the objective lens, the more light intake, and the stronger the resolution ability when the light is insufficient, but this will inevitably lead to an increase in the volume of the telescope, which is not conducive to carrying. You may feel at a loss for what to do, but if you can learn from each other's strengths, you can also buy a telescope that you like.

Limit magnification (limit magnification affects the maximum effective magnification that the telescope can get). Generally we believe that the limit magnification is 2 times the aperture of the telescope, for example: the limit magnification of the 102 1000 model telescope is 200 times, but this is only theoretically speaking, there are differences in optical quality between different brands of telescopes of the same model, and a telescope with excellent optics can exceed the limit magnification by about 50 times.

It is important to note that the magnification of the telescope is not always better. Once the magnification exceeds the limit magnification of the telescope (effective magnification), the image quality will be blurred and details will be lost due to invalid magnification.

Summary. According to the normal representation, the telescope is marked with an aperture of 120 mm and a magnification of 100 times. When I believe that binoculars will never reach such an aperture, a telescope with a 120mm aperture will definitely be in four figures, and such a heavy telescope is estimated to be sour in your hand.

If the magnification is 100 times, it is even more impossible, the magnification of the telescope is a very useless parameter, generally I hope to press the magnification of the telescope below 10 times, if it is 100 times, I don't know how much it will shake by hand, and only snipers will use such magnification, the landlord has played similar games and should know that the heartbeat under such magnification will make the field of view shake seriously.

If you follow the normal method of representation, the telescope is marked with an aperture of 120 mm and a magnification of 100 times. When I believe that binoculars will never reach such an aperture, a telescope with a 120mm aperture will definitely be in four figures, and such a heavy telescope is estimated to be sour in your hand. If the magnification is 100 times, it is even more impossible, the magnification of the telescope is a very useless number of parameters to change the parameters of the potato hidden judgment, generally I hope to press the magnification of the telescope below 10 times, if it is 100 times, I don't know how much it will shake by hand-held alone, and only snipers will use such magnification, the landlord has played similar games should know that the heartbeat under such magnification will make the field of view shake seriously.

Pro: You can observe things above 1000 meters<><
