Hello, I am a distributor of a military optical manufacturer.
If it's about the same, I'd recommend considering the previous one. Because of the latter one, there are too many fakes now!! If you don't know how to discern, it's best to be cautious!!
Hehe, friends downstairs, in fact, 8*50, the main reason is to consider that it is too heavy to take out, not easy to carry, and easy to damage.
Doctors can, if you talk so empty, it's hard to tell how to tell the difference between the real and the fake, unless you're in this industry. Even if you are in this industry, if it does not have a messy sickle pattern in appearance, the parameters are not indiscriminately marked, and the coating does not use red or yellow. Even if you are in this industry, it is difficult to tell if you don't really look at the effect!
I've seen a bushnell before, but it's just a **, I thought it was real at the time, but I asked the manufacturer to know that it was fake.
About the upstairs again, this does not see the real thing, to be honest I can't tell clearly :(

**There should be a price difference of a few dozen yuan. Why aren't there 50's? 8x50 is the best.

Can you talk about fake doctors? I also have one in my hand.
I just bought a 20x80 one, and I feel that the image is still sharp, but the manual is relatively thick, which is worse than my panda's.
-
Just looking at the parameters, I recommend the first one.
-
The Bushnell brand is still okay and can be considered.
-
The price is a lot.
The shark's 10*42 8*32 is good.

You do the work I know that the transmission of microwaves is in the line-of-sight range. Wherever the glasses can see, microwaves can be transmitted unhindered. In fact, you can roughly judge whether it can carry out direct microwave communication without a telescope, and it is best to have a telescope in order to better set up the installation site.
The telescope that meets your conditions is actually a toy, but your working environment in the field is best to use a nitrogen-filled waterproof and anti-fog one, that is to say, the high point will be more than 800 yuan, the magnification can be 6 to 12 times, the caliber from 20 to 50 is suitable for you, the image with a large aperture will be sharper, considering that the work is in the daytime, the caliber does not need to be too big, the bigger the heavier, you can consider this problem yourself.
Considering your working environment, it is better to buy a hard shell with cowhide, which can prevent you from accidentally bumping and bumping into the telescope while working.

It is too difficult to see microwave antennas at 2-10 km, and it is difficult for a 20x100 telescope to do it. You haven't seen a real military telescope, have you? A 5-kilometer microwave antenna is absolutely invisible. If you know more about telescopes, you'll understand, don't fall for the black businessmen.
-
The installation of microwave transmitting antennas and receivers requires a certain angle accuracy. The higher the accuracy, the less power the transmitter is required. If you use the debugging method I gave you, you can achieve an error of no more than a degree. - Senior Technical Consultant of Shanghai Boguan Telescope Store.

That's the military kind, the 7*40 kind of the 95 type.
Adaptable to all kinds of environments.

It is recommended that the landlord enter the North Brigade to learn the knowledge of telescopes, and then you will know what you use.
If the landlord wants to recommend, then I recommend the painting king 8*45, the optics are very good, but it's a bit big. There are two kinds of prices: more than 400 and more than 600.
If you want to be cheap, you can choose more than 400 yuan. The effect is basically the same.

I don't agree with what the upstairs says.
For a telescope, the larger the aperture is indeed the better, and the aperture determines the telescope's light-gathering capacity and resolution. It is the most important parameter of the telescope, but the ** of the telescope is also proportional to the cubic of the aperture, and the large aperture also means the rapid increase of the **.
As for the eyepiece upstairs said to be small (it should be the focal length) and the focal ratio is large, that is to improve the magnification.
The focal ratio (focal length aperture) of the telescope is relatively long and suitable for observing planets, and relatively small for finding deep-sky objects.
The eyepiece of the telescope has a lot of exquisiteness, a good eyepiece should be composed of three glass lenses, which can eliminate chromatic aberration and spherical aberration under a relatively high magnification, but the landlord gave only two eyepieces in the accessories H4 and H20, if there are only these two eyepieces, H4 will definitely be shelved by me, because the magnification is too large. In the process of using the telescope, I also hope that the magnification of the telescope is as small as possible, so that it is easier to find celestial objects and the image quality is not easily affected.
As for the landlord's telescope, which is a popular telescope, it is still okay as the first telescope to start. I have not used the brand of Xinglunte, but it is very hot at these times, and most of the telescopes recommended by netizens will know that this brand is recommended, I have not used this brand, so it is inconvenient to say more. But in the low-end telescope, I personally admire Boguan.
As for these popular telescopes, it is recommended that the landlord choose the Phoenix, after all, it is cheaper.
But I want to remind the landlord that the stars in the sky are not just a telescope to point to find, deep sky objects to find is to rely on a good basic skills, this is not easier than finding a grain of sand from the desert, a few days ago when I went out to observe the meteor shower by the way to find some deep sky objects, Aquarius M2 took me an hour, M2 in the brightness of deep sky objects steadily ranked in the top 30, but for me like a person who is more than less than the top (after all, looking for M31 in the back, M45,M42These old friends have been killed in seconds.,M34 that I've never looked for can also be done in 5 minutes.,It's probably not appropriate to say that I'm a complete newbie). Give an example of your own example to the landlord as a warning.
Personally, I suggest when the landlord can recognize the 30 constellations in the sky, and can familiarly point out the location of the five planets when to buy a telescope, at that time the naked eye alone may not be full, at this time into the telescope is better than now.

The caliber is too small, or 80EQ is better, and it is not expensive.

The logo is regular and reasonable. Strongly diss "guarding the lost", netizens don't know how to pretend to understand the behavior of misleading people's children
The aperture is 80mm, the magnification is 20x, the conventional logo of binoculars, and in the conventional model, it can be said to be the largest one.
But such large binoculars will also have certain problems, which are too heavy (2040g). It is difficult for people who have not undergone upper limb strength training to keep their hands stable for a long time (just imagine, what is it like to hold a four-pound thing and magnify the shaking 20 times?). )。
As far as my personal experience is concerned, a boy like me, who is healthy and exercises regularly, but does not specialize in exercising the strength of the upper limbs, insists on taking a break for two or three minutes.
In order to solve this problem, it is best to use it with a tripod, so this binoculars are also equipped with tripod screw holes.
Observing the effect, as a beginner's starter, is definitely more than enough. There are no less than a few hundred suitable deep-sky targets (nebulae, star clusters, binary stars) throughout the day. If you can find dozens of them, you're definitely getting started.
It can also be used for daily travel and viewing, but the main problem is still too heavy.
If the landlord is interested in the use of binoculars in astronomy, it is recommended that "Astronomy (Rabbit) Lovers" in "Discussion of Binoculars" and "Binoculars Deep Space Observation" two ** topics. The former is about the structure, parameters and tuning of the telescope, while the latter is naturally a deep-space target.

The arguments are all scribbled, needless to say that it is rubbish. Let's learn about telescopes for yourself.
-
The performance is not very good, but the cost performance is okay.
If you talk about the performance of optical products, you should start with four digits, otherwise you will talk about cost performance.
-
With such a large magnification, if you don't choose the expensive one, it may not be good for the eyes, and more than 700 is really average.
-
Look good at the appearance, if the use is the same as the instructions, then it is better.
-
Very good, I think it's good if you're going to buy it.

In large binoculars, 20*80 is a very common model. It is characterized by a large caliber, high magnification, and a small exit pupil diameter and visual field. Most of the more suitable uses are equipped with a tripod or column tripod to fix and observe some distant targets that need to distinguish surface details under the conditions of good atmospheric transparency and visual tolerance.
Due to its large weight and high magnification, it is difficult to use this type of binocular by hand. Under the scorching sun during the day, the near-ground targets are more susceptible to air turbulence (compared with the low-magnification lens). For use at night, it is also more difficult to find targets than with low magnifications due to its smaller field of view. In conclusion, the use of this mirror requires a support mechanism and a high level of skill.

Perfect, how is it?
Personally, I recommend buying a large-caliber double-barrel, if the budget is relatively rich, you can consider 15*70 or 20*80 racks on the tripod, it will feel very good, more affordable large-caliber double-barrels can consider the 20*80 of the wolf, 15*70 can consider Boguan, but Boguan's ** is more expensive than the above two brands. If the budget is tight, you can consider 7 * 50 or 8 * 42, these two types of telescopes can be handheld without the need to go on a tripod, you can consider pandas, sky wolves and Boguan, ** almost 300-500 is enough. Note that it is best to purchase the Panda Telescope from its manufacturer or check with your local distributor.
To be honest, with our current capital, we can't afford this kind of telescope at all, so it's no wonder that the upstairs says so. >>>More
Good life. Heavenly secrets must not be revealed.
Summary. Hello, I'm glad to answer for you, the following is the answer to your query, I hope it will help you: the seventh day of the sixth month of the lunar calendar in 1995 is about 6 7 o'clock to give birth to a girl. >>>More
