I want to buy a telescope! But I don t know what kind of good!

It's not bad, but I'm going to tell you: the telescope is not the larger the magnification, the better, for some unprofessional telescopes, sometimes the magnification is not good, that is to say, there will be blurry in the distance, if you want to buy a little more professional, it is best to choose some waterproof and anti-falling. I think it's better to return the iris (some of the people on the market say that the iris can have night vision, but in fact, it is a deception to consumers, and the level of night vision is often more than 1,000 yuan!)

I know a little bit about telescopes, if you really want to buy it, you should add my Q, okay, I'll tell you some useful knowledge. 183127650 just note that you're a "friend".

Up to 450 times, buy this "Yili Astronomical Telescope 80400" is not bad, "80F900B.""Apollo II"Type refracting astronomical telescope, "this is not bad, and there is" A114F900B, Saturn, "reflective sky".

Zeiss 522073'It doesn't cost 500 yuan, the multiple is 200 times. Focal length 2000x;

The data on the 3rd floor is very problematic, and at first glance it is a statement that I don't understand.

The magnification of the general astronomical telescope should not exceed 150 times, if the magnification is too high, 1 is to magnify the celestial body and also amplify the atmospheric disturbance, and the object you observe will be blurred or shaky; 2. If the magnification is too high, the image will be dark, and even the edges of the celestial objects will become similar to the background. An important parameter for astronomical telescopes is aperture, and generally speaking, the larger the aperture on a budget basis, the better.

How can astronomical telescopes observe land, but because the imaging mechanism is different from binoculars, the observation effect is not very good, if you want to observe ground targets and want to observe celestial bodies, it is recommended that you buy a large-aperture binocular. The best choice for hand-held binoculars is 10*50 or 7*50. If you have the conditions at home, you can buy a bigger one, such as the 20*80 of the Sky Wolf or the 25*100 of Boguan, or even the Sentinel Mirror of the Panda.

Personally, I recommend buying a Sirius good.

I can't see anything if I can't use it cheaply!

The specific selection method is as follows:

1. Sturdiness.

Telescopes are mostly used outdoors The plastic shell is not very protective, and it is easy to shift the prism group due to excessive temperature changes, so you need to know that as long as there is a slight deviation in the parallelism of the binocular eye axis, it will make the eyes tired and uncomfortable, and even headache and want to vomit if you use it for a long time.

2. Weight and feel.

The telescope should not be too heavy, otherwise it will make people tired after a long time of use, make the hands tremble and unable to see the target clearly, and the telescope should not be too light, otherwise it is easy to operate and watch stably due to shaking. With the ergonomic combination of Swarovski, the products enjoy a good sense of balance and a first-class feel, making the most of their optical properties.

3. Magnification (should be between 8 times and 10 times).

The telescopes are marked with the words 10x42'8x30, the former representing magnification and the latter representing the objective diameter. Looking at a bird standing at 100 meters with a 10x telescope is as close as seeing it at 10 meters with the naked eye.

4. Generally, the handheld should not be more than ten times, 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 it is best to use 7-8 times at ordinary times, because the high multiple generally means that the field of view is relatively narrow, and the field of vision is very narrow.

5. If you just look at the scenery and travel, 8*40 is already the limit, and 7*50 is too heavy, so it is not recommended to choose.

1: You have to understand the type of telescope to know which one to buy, first let's take a look at how to choose binoculars, there are a variety of binoculars on the market, some are used to enjoy scenery, sports competitions and theatrical performances, some are used to observe birds and other animals, and some are used to enjoy the magical and beautiful celestial bodies in the night sky.

2: What do the numbers in the telescope model represent? The best binoculars on the market are marked with such numbers:

The number in front of the 7x35, 15x70, etc. x "represents the magnification, and the number after the "x" sign represents the diameter of the individual objective of the binoculars. The magnification of the opening angle of the target when viewed through a telescope is equal to the ratio of the focal length of the objective lens to the focal length of the eyepiece. The magnification of the telescope can be changed simply by changing the focal length of the eyepiece.

3: Is it better to have a larger magnification? Most people believe that the higher the magnification of a telescope, the better they can see, but the opposite is true, the higher the magnification, the worse the image quality and the blurrier the view.

Generally, it is most appropriate to choose a magnification of 7 or 8 times, like it will be brighter and more stable, 4: What are the main factors that determine whether you can see clearly? The larger the clear aperture of the telescope, the stronger the ability to collect light, and the clearer the image will be seen.

The increase in the aperture of the objective lens makes the telescope bulky, otherwise it would be impossible to hold it steady without a tripod.

5: What factors affect the brightness of the observed scene? If you divide the objective aperture by the magnification, then you can get the diameter of the beam in millimeters through the telescope to the eye. The more light your eyes receive or information about the object being observed.

Waterproof, moisture-proof, fog-proof and portable.

It depends on what you're used for, but if you're interested, you can search for the "Giant Eye Telescope".
