Telescopes within 230 yuan are recommended

Beijing Galaxy Telescope will answer for you:

At present, the domestic binoculars are relatively good, especially the binoculars, the series and models are more, and the reputation is also good.

For binoculars, the higher the magnification, the better, the magnification of binoculars is 7-10 times, if the multiplier is too high, a slight shaking of the hand will affect the observation effect. In terms of caliber, it is relatively better around 50, with a large aperture and a large observation field of view and high comfort.

Here are some things to keep in mind when buying binoculars:

Two parameters are important to choose binoculars, one is the aperture, one is the multiple, like 7x50, or 8x42, and one: the number before the X number is the multiple.

Ordinary binoculars, the multiple is more than 7-10 times, generally not more than 12 times, if the multiple is higher, it will tremble when held, affecting the observation effect, 10 times the telescope to see the scene at 100 meters, which is equivalent to 10 meters in front of you (100 divided by 10 times, 7 times is equivalent to the feeling of getting closer to 14 meters) The feeling of the naked eye.

2: Caliber: The number of amps behind the X number is the caliber.

If you want to observe a large area, it is recommended to choose a large aperture, in ordinary binoculars, 50 aperture is relatively large, but the large aperture telescope is relatively large.

Three: the ratio of caliber and multiple:

Brand model recommendation:

Binoculars are based on different brands, parameters, and performance, and the gap is also very large, so you can choose the right one according to your own use and economic situation.

Low-end binoculars are recommended:

Boguan surfing series, like 7x18, 6x18, 8x22, 8x25 of the mountain eagle series, these are relatively elementary binoculars, very practical, the appearance is more fashionable and beautiful, the volume is relatively small, very easy to carry, more suitable for watching concerts and ball games, and also suitable for young people and students, ** are below 200 yuan.

Low-to-mid-end binoculars are recommended:

Boguan Hunter 7x50 and Traveler 10x50 These two reputations are very good, the caliber is large, the multiple is more reasonable, ** is also moderate, about 400 yuan, cost-effective, very suitable for travel and sightseeing, belongs to the mid-end binoculars are more affordable, the shape is relatively mature, suitable for men.

Mid-to-high-end binoculars recommended:

Boguan hollow 8*42 and optimistic 10x42, these two series are metal mirror bodies, themselves are waterproof and anti-fog, the viewing quality is very high, the imaging is sharp, the definition is high, the coating technology is also very good, and the quality is high. **Around $1000. Binoculars that belong to the mid-to-high-end.

You can go to the Galaxy Telescope Knowledge Zone to see, you can directly search for "Galaxy Telescope", there is a lot of relevant knowledge about the purchase, maintenance and use of telescopes.

Boguan traveler 10 * 50, OK, it is estimated that 300 can be done, novices are OK, if the budget is high, it is recommended to buy a foreign one, domestic is not very good.

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. A good telescope, that is, you choose a more formal product at the price you want to invest.

4. Regarding the identification of telescopes, as an ordinary person, the simplest is probably from some details, such as whether the merchant's propaganda is regular, whether it is honest, and whether the product has some performance that needs to be avoided, such as "Japanese cherry blossoms", "night vision infrared", "shimmer", "Russia" and other deceptive propaganda, or a very risky direction that should not be considered. Wait a minute. In this regard, we can look at popular optics, which has some basic knowledge introduction, which is relatively comprehensive.

Judging by your question, I may not know much about telescopes, so I will talk about it slowly.

One is about "distance" and the other is about "price".

1. In fact, the telescope does not have the farthest distance to look at, and the usual "can see 2000 meters" and "can see 3000 meters", many of which are false propaganda of some inferior products. Just think about it, I'll give you an example:

When the weather is good, you can see the moon 300,000 kilometers away with the naked eye without a telescope, and when the weather is bad and there is dust or fog, even with a telescope, you may not be able to see the traffic lights 200 meters away, right? Hehe.

So, there is no such thing as how far you can see – this has nothing to do with telescopes, it has to do with weather, air conditions, environment, etc.! Of course, the premise is that the regular telescope, the kind of inferior product produced by a small workshop, is itself blurry because of problems such as the accuracy of the parts.

2. Then you may have to ask, what is the difference between different grades? To be honest, there is no standard for this, but roughly speaking, this kind of thing is of different grades, according to different requirements, to customize the material grade and processing accuracy. It affects the effect, that is, the image quality, the clarity of the picture.

3. The telescope is mainly too many inferior ones on the market now, and this requires you to know more basic discernment knowledge. If you choose regular production, there will be no problem. The point is that there are too many inferior and counterfeit ones, and this one can be taken a look.

There is a lot of knowledge introduction in the back, from some identification knowledge, to the production of telescopes, materials, processing, lenses and other knowledge. You can take a look.

4. Speaking of **, in fact, when this kind of problem was in the past, it was said that "more than 100 yuan, you can buy regular products if you are careful", but now it is a little different, it is recommended not to be less than 200 yuan. This year, the field of telescopes has changed a little more, because the price of raw materials has risen, the factory does not make money, the standard is lowered, and the quality of the products within the 200 price range is obviously not as good as before, and I have been in contact with several products like this. Therefore, it is generally not too recommended to choose this range at present.

I don't know what you mean, any mirror can see 1000 meters, less than 200 yuan, this and this... What do you mean by 1000 meters, do you want binoculars or skywatch?

There are many kinds of words on the bottle, and if you look at it with the naked eye, it is difficult to read the large ones from four or five meters away, and the small ones from one meter away. I don't know which one of your requirements will prevail?

There's more than one word on the Coke label.

If you only want to be able to read the largest font at a distance of 500 meters, you can do it. The general 80 100mm aperture and 800 1000mm focal length astronomical telescope sold on X Bao can meet the requirements with a 6 10mm focal length eyepiece. However, there must be a stable bracket to avoid the shaking of the primary mirror under high magnification; It is also required that there be adequate illumination at the location of the observed target (beverage bottle).

If you want to see the smallest font from 500 meters away, it's a real struggle to choose a telescope – it requires the mirror to have an effective magnification of more than 500 times, which is an indicator of a top celestial vision with an aperture of more than 200 mm. Moreover, this kind of long-distance observation near the ground is very demanding on the state of the air, and the air turbulence will turn the image in the telescope into a pot of boiling paste, and the slight fog or haze will give your target an indiscriminate blur. So, forget it.
