What brand of telescope can see people s facial features clearly at three kilometers

Three kilometers, that is, 3,000 meters away. It depends on the magnification of the telescope. With 10 times, it is equivalent to you being 300 meters away from this person and seeing with the naked eye; 20 times is 150 meters away from him.

It seems that your requirements are quite high, and ordinary people can't see other people's facial features when they are 150 meters away, right? The bird-watching mirror has a high magnification, such as 60 times, which is equivalent to being 50 meters away from the person's naked eye, and it seems that it is still difficult for the telescope of this magnification to see the facial features of a person 3 kilometers away. Then go on the astronomical mirror, 120 times, which is equivalent to 25 meters to see with the naked eye; 300 times, which is equivalent to being 10 meters away from him naked, this is about the same, right?

But not to mention that in fact, astronomical mirrors are rarely 300 times (don't raise the bar, I know that a certain treasure can even be stacked up to thousands of times with a magnifier and the like, but that is meaningless. In fact, if you want to get a passable imaging effect, the general consensus of the astronomical scope is that the maximum magnification should not exceed twice the aperture of the objective lens), even if you get a big guy, you have to understand that the magnification is so high, the field of view is very small, as long as the target moves slightly, it will run out of your field of vision, and it is very troublesome for you to find the target when using high magnification (if you don't understand what the field of vision is, go down yourself, and the hand is very tired, so you won't be verbose). And the high magnification will also have the disadvantage of dim imaging, and then your field of vision may be dim and blurry, what do you think you think?

To sum up, your requirements are actually very high, and I think there are very few brands and models that can meet them. Don't think of the telescope as an artifact, after all, it's just a few.

Ten, hundreds, thousands of gadgets, not as expensive as your ordinary smartphone, what great effect can it have? I've been playing with all my hands for more than ten minutes, it's interesting enough, I don't want your wealth yet.

The clarity of a telescope depends not only on the brand and model, but also on factors such as the telescope's aperture, magnification, and viewing environment. However, in general, to see a person's facial features from three kilometers away, a high-performance telescope is required.

According to the principle that the distance between the human eye and the face can be distinguished within 20 meters, to see the facial features of a person 3,000 meters away, it needs a magnification of more than 150 times, and to achieve such a high magnification, the diameter needs to be more than 80mm.

There are many telescopes on the market that meet this requirement, such as Xingtran 80EQ, Boguan 80EQ, etc. Note that the viewing environment can also affect the performance of the telescope, so make sure you choose a suitable viewing location before using the telescope.

The landlord is talking about the imaging ability of the telescope, the telescope is just to bring the distant scenery closer to the **, as for how far the distance to observe, what kind of effect do you want to see, these are related to the lens material of the telescope, workmanship, magnification, and the size of the objective lens Theoretically, the magnification of the telescope is large, the objective lens is large, the lens material is good, the coating is good, and the workmanship is precise The imaging effect of such a telescope is very good.

Summary. Dear, how many meters can the best telescope see, the telescope does not look far. Depending on the resolution and aperture, it can be said that the telescope can see how far away the object is in detail.

For example, an astronomical telescope with a resolution of arc seconds can resolve details on the moon up to 180 meters in size. The ordinary astronomical mirror is also called the universal astronomical telescope, which varies from 200 to 1000 away, and has a variety of classifications such as refractor and reflector, with a magnification of about 15-70.

Dear, how many meters can the best telescope see, the telescope does not look far. Depending on the resolution and aperture, it can be said that the telescope can excite the level of detail to see beyond the object. For example, an astronomical telescope with a resolution of arc seconds can resolve details on the moon up to 180 meters in size.

A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. It uses the light refraction through the lens or the light is reflected by the concave mirror to make it enter the small hole and converge for imaging, and then through a magnifying eyepiece to be seen, Ming Jian Song is also called "bright canopy clairvoyant".
