What kind of hand held telescope can you buy for about 500 yuan?

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, multiples in 7-10 times more, generally not more than 12 times, if the multiples are higher, the hand will tremble, affecting the observation effect, 10 times the telescope to see the scene at 100 meters, equivalent to 10 meters in front of the eye (100 divided by 10 times, 7 times is equivalent to the feeling of approaching 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. Support.

Hello, although this **, it is more difficult to buy a regular telescope, but if you are careful, you can also find it. Generally, there are fewer regular products below 100, and even if they are regular, they are relatively low-grade.

Regarding your requirements, see clearly and far away (although the statement is not standard, but I know what you mean, that is, at this price, you can buy as much as possible "good" right) - in fact, as long as it is a regular product, the materials and accuracy are generally better, so the basic comfort and clarity can naturally be guaranteed. And the price of 100 yuan, it is indeed a price point of mixed fish eyes, inferior products are generally more than 100 pieces, you can look at the basic identification, there is probably an understanding of the fake a lot now, basically can account for more than 9 percent, and there are some common false propaganda, such as the so-called "infrared", "Russia", "cherry blossoms" and so on. - About the brand, it is not recommended to be too superstitious about the brand, because there are too many fake brands now, random counterfeit brands, like the most common on the market, what bushnell, kenko, tasco, Bego's, etc., etc., very cheap, within 100 yuan, and even some hundreds of yuan, most of them are some inferior products, indiscriminately pasted.

In the past, we were able to get some export tail goods without any quality problems, but now, the factory requirements are becoming more and more stringent, not to mention that there is no quality problem, that is, there is a quality problem, are not allowed to flow out, all controlled, we recently want to engage in a product for the United States bushnell OEM, we have to discuss with the manufacturer, remove the brand, can it be provided.

Therefore, those with foreign trademarks in the domestic market are almost not real, and there are really fewer and fewer of them. Because the real OEM is all in charge.

After understanding the basic identification given to you above, if you are careful, there is basically no problem.

Panda telescope 8x40 8*40 Yunguang Factory 298 produced 8 times the comfort rate,**122 yuan is very affordable, it is a brand telescope, and it is**, it is recommended that you buy, you can buy it on**.

This budget, whether you buy a single tube or a double tube, is a bit low. It's like if we buy a fish, the fish is delicious, 10 yuan can buy a fish that is not fresh and a little broken, and 20 yuan can buy a fresh fish.

I want to buy a bad fish that can't be eaten or used, so it's better not to buy it, right?

The price of 100 you are talking about now is facing a similar situation - this price is too risky, similar to grabbing a prize, it is not recommended that you take the hard-earned more than 100 yuan to gamble on luck, try to increase the budget a little more, and try to increase it to more than 200. I think it's better.

If you really want to choose this price range, then I have a few suggestions for you:

1. Don't touch the small monoculars whose magnifications can change, this kind of telescope is specially designed to fool novices, such as "15-35x21" and the like. Relying on unreasonable multiples to attract attention, it can't be used when you actually buy it.

2. Don't choose some products that call themselves "Russian" or "military" or "night vision" or "infrared", which are typical false propaganda.

3. Don't choose some products with unreasonable specifications, such as 12x25, or 20x32, and even I personally feel that 10x25 is considered a bad specification to a certain extent.

In short, to learn more about some basic knowledge, you can take a look at popular optics, there are some basic knowledge introductions, which are more comprehensive.

The point is to identify.

Want to buy an astronomical telescope, or binoculars?

If you are binoculars, you can go to the "sales factory" to see, the above are some export-oriented products, the quality is very good.

Tianjin Science and Technology Museum has it for sale.

1.Prism material. Generally used more prisms are BAK4 and BAK7, the refractive index of these two glasses is different, the refractive index of BAK4 is high, for the PORRO prism made of BAK4 material, it can fully reflect 100% of the incident light when it does not consider absorption, and BK7 can only reflect about 83% of the incident light, so the light efficiency of BAK4 is high, but it is also expensive.

2.Multiples are important. The magnification of the telescope is equivalent to how many times you bring a distant object closer, if you wish to hold the telescope in your hand.

The multiplier is best chosen between 6-12 times, the multiple is too low, I feel that it cannot meet the requirements, if the multiple is too high, the imaging jitter is very strong, it looks blurry, and there is a little dizziness after a long time. At the same time, high-magnification telescopes are generally relatively large and heavy, and they need to be fixed with a tripod to see. 3.

The telescope is nitrogen-filled and waterproof. Because the outdoor environment is relatively harsh, the inside of the telescope is filled with nitrogen and waterproof, and the nitrogen inside the telescope can prevent the internal lens of the telescope from fogging and mildew, and the sealing of the telescope is very good, so water vapor and dust cannot enter the inside of the telescope, so the durability of the telescope is guaranteed. 4.

About telescope apertures. The larger the aperture, the larger the observation field of view and brightness, which is conducive to observation in low light, but the larger the aperture, the larger the volume weight, and the higher the cost, which can generally be selected between 30 and 50mm according to the need. 5.

Telescope construction materials: In order to reduce costs, most of the ordinary telescopes on the market use plastic mirror bodies and tubes, and only a few high-end products and military models use all-metal structures, which are expensive, but their durability is incomparable.

1. Looking at the parameters, the parameters of the telescope mainly include magnification, objective lens size, field of view, and the exit pupil distance.

2. Generally, telescopes are marked like this *40 and so on, in which the front number indicates the magnification, and the back number indicates the size of the objective lens, the unit is mm, 7*50 means that the magnification is 7 times, and the diameter of the objective lens is 50 mm.

3. Generally, it should not be more than ten times handheld, because the multiple is too high and it is easy to shake too much, and it is impossible to see the target clearly, especially the military, there are almost no more than ten times at home and abroad, so don't think that the military is the multiple is high, and those who boast thousands of times are fooling rookies. It is best for us to use 7-8 times for ourselves, because a high multiple generally means that the field of view is relatively narrow, and the field of view is very narrow.

4. I recommend the diameter of the objective lens of 40, because I use Boguan 8*40 myself, I feel that the volume and weight are already the limit, and it seems not small in my boy's hands, and it is really unbearable to hold it for a long time, but if you are specialized in stargazing, then it is recommended to use 7*50, because a larger objective lens diameter means a greater amount of light, and you can see fainter stars when you look at the stars at night, it is best to install it on a tripod, or the average person really can't move for more than 1 minute.

5. Field of view: Generally measured by the degree or the width of how many meters (or feet) can be seen at a distance of 1000 meters or 1000ft, of course, the bigger the better.

There are two main types of telescopes: refractors, which use lenses to collect and concentrate light, and mirrors, which use mirrors to collect light. To choose the right telescope, you must first understand the relative advantages and disadvantages of both telescopes. Measure the telescope.

You can take a look at this, introduce some well-evaluated, cost-effective telescope brands, you can refer to the selection of telescopes, and the introduction is detailed.

If you look at it with the naked eye, 10,000 and 1,000 are not much different, and if you want to see more, you still have to take pictures.

About 10,000 can buy a good 100 caliber ED mirror, but you also need an equatorial mount with tracking function, and a DSLR camera. In addition, it takes about 30,000 yuan for the guide mirror, the guide star camera, various filters, etc.

If you don't take pictures, 1,000 is enough, and if you take pictures, 30,000 is not enough, so about 10,000 is an awkward position.

Handheld, the magnification should not be higher than 10 times. If you use 10 times, it is equivalent to looking directly at the plane 50 meters away, and you can walk about 50 meters away from the plane to see if you can read the words clearly. It is better to walk about 80 meters, because the telescope imaging will be discounted.

There are also reasons for the shaking of the hand. So what you can see with the naked eye at 80 meters, basically a 10x telescope can see about the same at 500 meters. If you put it on the shelf, the clarity can be improved a lot.

You can choose 10*42 10*50 models, and it is recommended to have a small caliber of 10*42. It is light and can be held more steadily. You can choose the Shark, the Vertical up to the low-end series. Boguan can also be. It's all within your price point.

Finally, if your little daughter is not more than 10 years old, it is not recommended to use a telescope, it will be bad for her eyes.

I estimate that 10x may be a little lower, but the multiplier is high, and the more you shake, you still can't see what you can't see. So the upper tripod is the best. The upper tripod can go up to 15 times or even 20 times. However, the caliber should also be increased, and the addition of shelves will exceed your budget.

m of the plane? Is your home close to the airport? Then this requirement can be met.

The zoom is a little larger, but it is easy to hold unsteadily, and the field of view is small, so it is not easy to aim at a moving target. So I feel that you can think about 8x, actually looking at a small object in the distance, and 10x jitter will cancel out its magnification, resulting in inability to see. Therefore, the military is generally more common.

4. If it is about two hundred, you can look at the price of Polzne 8x42,210 of Volkswagen Optics.

Phoenix 60700 No, no, you have to hold it.

Sirius's 50's should work.
