I would like to ask the person who paid for the telescope there, and you can see animals in the fore

If you want to buy an ordinary telescope, you can't see animals at night, unless you illuminate the animals with strong light, you can see through the telescope, this is the basic principle of optics, the target can either self-emit or reflect light to be seen, which is also the reason why you can see during the day and can't see at night. If you want to buy that kind of night vision, it is relatively high, and there are low-light night vision devices that need to have starlight and moonlight to see** are more than a few thousand yuan, and there is a kind of thermal imaging **Ken can be higher. Thermal imaging is seen through imaging of the animal's body temperature.

1. There is no such thing. Thermal imaging is made up of a series of electronic sensor arrays, circuits, and screens. It's not something that can be made with a glass lens at all. And then there's the power battery.

2. I don't know if you have seen some false propaganda about telescopes, in fact, the so-called "night vision telescope", "infrared telescope", "shimmer" and "perspective" are the most common false propaganda. Considering the current chaotic market background, to put it mildly, if a merchant is very focused on promoting these things, then to a certain extent, you can think that this merchant is not particularly credible, at least not very down-to-earth.

3. I feel that you still don't know much about the telescope and are familiar with it, in addition to the above, there are some basic knowledge, you can take a look at popular optics, there are some common introductions to false propaganda on the market, which is more comprehensive.

I remember that it seemed like I could see about 1000 meters.

Look at how big the animal is. 200 meters to see a mouse, not a big problem.

And so on scale, you calculate the animals that you're going to look at.

Night vision. There is a 3x magnification. To be thermally ready for 1w or more, hunting.

Then it depends on how far away the LZ buys the telescope.

If you want different animals at different distances**, it is recommended to choose a 15-45x zoom monocular that can meet the needs at any time.

If you observe a fixed target at a fixed point, 10 times as many binoculars as far away will do. When choosing, try to choose nitrogen-filled or argon-filled waterproof. Heavy moisture in the depths of the mountains Non-waterproof products or waterproof products are easy to get moisture into the lens barrel, resulting in water mist inside the lens that cannot be wiped off, and there will be traces on it when it dries.

Ten times as many binoculars, or a simple tripod will be.

That's a toy, but one hundred and fifty meters can still be seen, but those telescopes have a large color difference, can't see clearly, it is recommended that the landlord buy a little more expensive specifications are best 7 50 (personal preference for large caliber) focal ratio is best not more than ten, should have a field of view of 5 ° to 7 °.

It's okay to have light at night.

If there is no light, it cannot be seen.

Can you see, see clearly? The 50-piece thing is not clear during the day.

You can buy it, it's called low-light night vision goggles, you can find a lot of them online, ranging from 1000 to tens of thousands of yuan, and the imaging point is at least 2000 yuan, which is advantageous. There are also thermal imagers, but thermal imagers are more expensive, they are tens of thousands of yuan, and there are thermal imagers that can only see the outline of the animal.

There is no such thing as an "ultraviolet double telescope".

At present, there are infrared night vision devices and infrared thermal imaging cameras on the market, the former is generally used with infrared lighting (such as infrared flashlight), which can meet the obstacle identification and road observation of tens of meters and two hundred meters. The latter is expensive, but animals with a constant body temperature can be seen through thin shelters, such as leaves or blades of grass.

Thermal imaging cameras have very low image resolution and images in false color, so they can only be used to find targets, and they are difficult to identify (if you have a lot of experience with them), and they are generally used for military, research, and industrial surveying purposes.

1. There are actually many kinds of telescopes, and the telescopes for observing the scenery can be divided into handheld and desktop (tripod) high times. 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.

2. If it is handheld, whether it is a civilian or military telescope, there is a standard optimal multiples range for hand-held, that is, 7 10 times, among which, the most commonly used in the military is 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 can be easily misled.

And if it is a tabletop type, this multiplier range is relatively large because there is a tripod. But for observing the scenery on the ground, it is generally the highest and the highest, and in my experience, when looking at the scenery on the ground, the image quality begins to decline significantly after more than 25 times, because the air begins to boil, and when it starts at 35 times, it is meaningless.

3. The so-called "good telescope", that is, you choose a more regular product at the price you want to invest in :)

4. Regarding the identification of telescopes, as an ordinary person, the simplest is probably from some details, such as whether the merchant's publicity is formal, whether it is honest, and whether the product has some performance that needs to be avoided, such as.

Japanese cherry blossom "night vision infrared".

Shimmering "Russia" such deceptive propaganda, or a very risky direction that should not be considered. Wait a minute. This aspect can be seen.

Popular optics has some basic knowledge introduction, which is relatively comprehensive.

Generally, it takes 1000-2000 to buy a telescope from the past. In addition, astronomical telescopes are demanding on the environment in which they are used. It is necessary for the human eye to adapt to the darkness for more than 1 hour in the absence of lights, moonlight, sunny weather and no wind in order to maximize the function of the telescope.

Otherwise, you can only see the most basic celestial phenomena such as the Moon's ringed mountains, sunspots, Venus's waxing and waning, Jupiter's four Galilean moons, and Saturn's rings. Don't be fooled by the extreme magnitude of the telescope's design, it is generally difficult to exert the telescope's function to the ultimate magnitude. Telescopes are generally divided into two types: refraction and reflection, and I personally feel that the reflection type is better than the refraction type, but it is more expensive.

The biggest advantage of reflective compared to refractive is that there is no chromatic aberration. Because visible light is composed of different wavelengths of light, different colors of light will converge in different positions due to different refractive indices after refraction, which is chromatic aberration, but the reflective type does not have this disadvantage, because all light obeys the same law of reflection. However, there are coma and spherical aberration in the reflective type, and the edges of the mirror image will be distorted.

In addition, the astronomical telescope has some ancillary facilities, such as equatorial mounts, finderscopes, filters, photographic interfaces, extenders, and so on.

Among the domestic mirrors, Boguan, Daguan, and Tianluo have a good reputation.

Hello, I am a distributor of a military optical manufacturer, and our factory produces night vision gun sights for the troops.

If you are more interested in the so-called "night vision telescopes" that often appear on the Internet, then you should be reminded that this is a common false propaganda for inferior products on the market now.

I don't know if you know, the so-called "how far to see" and "night vision binoculars" - are common deceptive propaganda for some inferior products. - There is no such thing at all.

If you follow this "guiding ideology", I'm afraid it will be easy.

You can pay more attention to the local gymnasium nearby.

Also, pay attention to optical stores, photographic equipment stores, sometimes there are such things. Ordinary stores, may not be easy to find.

However, there are a lot of fake products now, counterfeit and inferior products account for more than 95% of the market, and the trouble is that there are false propaganda, such as "night vision", "infrared", "Japanese cherry blossoms", "Russia" and so on, so it is recommended that you understand the basic knowledge: you can look at the basic identification aspects.

Particular attention is paid to the issues related to multiples, military, night vision, etc., that is, the introduction of some common false propaganda.

What can really see at night is the night vision device, which requires electricity, relying on the amplification and excitation of some electronic components to image and enhance the weak light at night in nature.

The cheapest may also cost more than 1,000 yuan, but those below 2,000 yuan have poor results.

Night vision devices and telescopes are completely different things, night vision devices are almost not magnified, only 2 or 3 times, and they cannot be used during the day, and the clarity is definitely far from the telescope, because it is imaged by the screen.

There are a variety of telescopes on the market, their appearance, size, ** and use are different, some are used to enjoy scenery, sports competitions and theatrical performances, some are used to observe birds and other animals, some are used for fixed-point monitoring (such as forests, electricity, public security departments, etc.), and some people use them to enjoy the magical and beautiful celestial bodies in the night sky, etc., so if you buy it, you mainly choose it according to your actual needs. If you want to buy a brand, you can consider Panda Panda Telescope, Boguan, Sky Wolf, Phoenix, Canon, these are all very good, and they are some of the lists I inquired about on the top ten brand networks maigoo, I hope it will help you. Hehe...

It depends on what you want to achieve:

If it is for hunting, it is recommended to use 98 factory 10*50 binoculars (JYSW10X50), nitrogen-filled and waterproof, good impact resistance (can withstand 20g overload), the mirror comes with a curve division, can roughly measure the distance and orientation of the target, the weight of the whole mirror does not exceed 2kg (including accessories) Good portability, the price of the hand is about 1200 1600 left filial piety pants right (**).

If it is only for observation, it is recommended to use 20 * 80 bird watching goggles, and the domestic **** is about 650 (waterproof, excluding tripod weight, if you want to be fully waterproof, the function of measuring the distance is about 1100, and the tripod is counted separately.) Imported brand products** are generally above 5 figures.

I suspect that maybe any telescope can't reach it.

1. First of all, if it is a hand-held telescope, the hand-held telescope has a standard optimal multiple range, that is, times, all hand-held regular products are in this range, among them, the most commonly used in the military is 7 times and 8 times. According to your example, if you use a hand-held telescope to look at something 1 kilometer, it is about 120 meters or so. Can you imagine that at a distance of 120 meters, do you see a light bulb clearly?

It's almost impossible.

2. Theoretically, to achieve your effect, let's calculate the multiple, assuming that you can see a ladybug, or the farthest limit distance of the filament, is 8 meters, then, 1 kilometer, divided by 8 meters, is more than 100 times. This effect can only be achieved theoretically if this multiple is reached.

But - for the observation of objects on the surface of the earth, there is a limit to the telescope, no matter how high the multiple, you can't see more burning details - my experience, even if there are more than 1000 desktop high-magnification products, the multiple of the limit is about 30 times, and then up, you can't see more details, in fact, 30 times, it's worse, to ensure a more perfect image quality, in the observation of ground scenes, my experience is not to exceed 25 times.

Therefore, holding a telescope will definitely not achieve your effect, and a desktop (tripod) high-magnification viewing scope (not referring to astronomy) will not be able to achieve the truth.

Why observing astronomy, more than 90 times is sometimes no problem (although the air is also boiling more violently), this has other reasons, and it has nothing to do with the topic, so I won't talk about it. Astronomy can only be used to look at the stars.

It is recommended that you can learn about the relevant knowledge, you can take a look.

3. I want to add to what I said above: In fact, for some limits, like a sniper and a ruler, even the beating of the heart must be estimated. And like a telescope with high magnification, even if it is cloudless and clear with the naked eye, the flaws in the air are magnified when viewed at a high magnification.

It's like looking at the scenery 20 times, and the air is boiling. Therefore, for telescopes, as long as they are not in vacuum space, as long as there is an atmosphere on the surface of the earth, then the multiplier cannot be infinitely increased with imagination. Generally more than 25 times, especially to 30 times, and further up, looking at the ground target is of little practical significance.

4. Combined with the example you asked, 1000 meters, if you look at it 25 times, it is about 400 meters, can you see small animals in the grass? I think it's unlikely.

So it's unrealistic to think that this is a requirement.
