The definition of your so-called high multiplier is not clear! Because it depends on what you're looking at. How far away !
Generally, the monotube is divided into 21mm, 25mm, and caliber, which are 8-10 times. Then there are 50mm, 60mm, 65mm, 80mm, 85mm, 90mm, 100mm, aperture objectives! If you want a large multiple, you must choose a large caliber!
That's a big principle! As for the quality of the lens material, it is another matter! At present, the more famous ones are nothing more than Nikon, Zeiss, Swarovski, Kowa, and Laika.
But these ** are very expensive! It depends on what your budget is!

Sakya.
The Saga telescope adopts a ridge structure, the eyepiece and the objective lens are in the same straight line, the volume is smaller, the image has a stronger sense of realism and distance, but the light loss in the prism refraction is more, and the assembly accuracy is higher, so under the same observation effect, the ridge is higher than that of the telescope with the Paul structure**.
A monocular is a kind of visual optical instrument used to observe distant objects, which can magnify the small opening angle of distant objects at a certain magnification, so that it has a large opening angle in image space, so that objects that cannot be seen or distinguished by the naked eye become clear and recognizable.
Cintron
Xingtron has several monocular bird-watching goggles are good, very cost-effective, 20-60x80 (1500 yuan) and 22-67x100, (2100 yuan) These two are adjustable zoom, look at the distance to use high power, look near use low times, these two can be viewed, bird watching, and the starry sky at night is also very good, and the crater of the moon is very clear, but both of these need supporting role frames.

Binoculars 7 to 10 times are best.
Typically, binoculars with a magnification of 7 to 10x are sufficient for everyday use. A telescope of the same quality will have a clearer image and a wider field of view (the range you can see) when the magnification is lower.
How to choose a telescope:
1. Choose the appropriate multiple.
Telescopes are not always better at higher magnification. Binoculars are represented by two numbers, such as 7x35 or 10x50. The second number is the diameter of the primary lens (objective) in millimeters; The 7x35 lens has a diameter of 35 mm, while the 10x50 lens has a diameter of 50 mm.
The lower the magnification of a telescope of the same quality, the clearer the image will be, and the wider the field of view (the range you can see). If you need a wider field of view, such as from a football match, choose a lower magnification.
2. High-magnification binoculars can be selected for long-distance observation.
If you're hunting in the mountains or in an open area, you'll need to use binoculars with larger magnifications, such as 10x or 12x. Note that the higher the magnification of the binoculars, the darker the image. While the image you see will get bigger, your field of view will narrow, and it will be difficult to keep the image in steady focus.
If you choose a magnification of 12x or higher, purchase a pair of binoculars with a tripod mount to mount and stabilize the binoculars when needed.
3. Binoculars for bird watching or low-light activities with a larger lens are preferred.
The larger the objective, the wider the field of view of binoculars, which is more conducive to spotting and tracking birds when birdwatching. They are also able to collect more light, which is important for low-light activities such as dawn or dusk hunting. If you're interested in astronomy, use the largest possible objective (70 mm is common) and low magnification to observe large, faint objects like nebulae and the Andromeda Galaxy (M31).
Note that the larger the lens, the more weight the telescope may be. In general, standard-size binoculars have an objective lens diameter greater than 30mm, while small binoculars have an objective lens diameter of less than 30mm.
4. Determine your budget range in advance.
More often than not, the more expensive top-of-the-line binoculars have higher image quality and are also more durable. However, there are also a lot of cost-effective binoculars that are durable enough and have good optical quality to meet your daily needs. Therefore, determine your budget range before choosing.
5. Determine the weight of the binoculars you can bear.
If you're planning a long trip or don't have a lot of storage space, you may be better suited for lightweight binoculars. Scenes where telescopes are used are especially important here. If you're planning to wear them around your neck while hiking, heavy binoculars can be a real, burden.
6. Do you need waterproof binoculars?
If you don't plan to use it in bad weather or wet conditions, you can ignore the waterproof performance. If you're planning to take them on rafting or skiing, opt for waterproof binoculars. <>

In addition to the brand, the most important thing for the telescope is to identify, because there are too many fakes in the domestic market. This must be the most important issue to pay attention to. That is, more.
The most fake, to name a few: Tasco, Bushnell, Nikula, etc., the first two, really too few! The last one is that there are more counterfeits, and if you want to choose, you must pay attention to identification.
Some junk brands (the products are actually produced in small workshops, or the quality is very questionable): "Japanese Sakura" and so on, "Phoenix" is not very good.
Note: the so-called "Russian", "military", "night vision" are the most common names for inferior products.
As for Seedele, it is actually a brand with a very low cost performance, in fact, telescope enthusiasts basically do not buy Seedele. Because**Compared with its effect, it is too high and the cost performance is too poor.
Boguan is actually also a low-cost brand recognized by telescope enthusiasts, and their astronomical products are OK, but binoculars are not recommended. All expensive.
How to net downstairs to give people this kind of recommendation l
The key to the usual use of telescopes is practicality, in fact, as long as it is produced by regular manufacturers, there is no problem. The main thing is to choose the specifications well. 7 50 specs, too heavy! For normal use, it's best to buy a moderate specification, because that is generally easy to carry.
In fact, the main choice now is not the essentials, it is more than 90% on the market, all of which are counterfeit and inferior products, you have to know the basic distinction!
Take a look at market and product knowledge.
In addition, it should be reminded that do not buy military telescopes, if you are not an outdoor adventurer or something, there are introductions in it, why, take a good look, it may be more beneficial for you to understand and choose.

With this budget, you can start Boguan's Hunter II series, 7x50 or 10x50 is good.

Binoculars and monoculars have their own advantages and disadvantages. In response to this problem, let me introduce it to you.
Binoculars can provide a wider field of view and a more comfortable viewing experience because of their double-tube vertical structure, such as stability and comfortable holding, reducing eye fatigue, etc. This is very important for observers who use telescopes for long periods of time.
In addition, binoculars have a relatively small magnification, so they are suitable for observing relatively close objects and scenes, such as birds, athletes, racing cars, and flying machines. In addition, focusing is easier because binoculars have fewer parallax cases of occurrence, making them easier to see than monoculars.
A monocular, on the other hand, consists of a single telescope tube. Due to its relatively simple structure, it is relatively inexpensive. It can also be used for astronomical telescopes and telephoto photography, etc., and its multiples are generally higher, so it is more suitable for observing distant scenes and celestial objects, such as:
High-magnification monoculars can be used for solar flare observation as well as detailed observation of the lunar surface. In addition, the monocular is relatively light in weight and easy to carry, making it suitable for outdoor activities, travel, and other places.
In general, the choice of binoculars or monoculars depends on the specific application and personal preference. If you need to observe activities up close or have a more comfortable viewing experience, it is recommended to choose binoculars. If you need to observe distant celestial objects or need to carry them with you, it is recommended to choose a telescope.
In addition, appropriate ** and suitable functions are also factors to consider when choosing a telescope. <>
Presumably you're talking about binoculars, and you can't buy any so-called "brand" for 100 yuan. Even if it is the domestic entry-level brand "Boguan", if you want to buy a 7 50 twin tubes used in the past, you need at least 300+ prices. >>>More
I said, don't you want your own eyes, as long as the telescope is not standardized, the impact on the eyesight is great, not to mention the astronomical telescope, I advise you to buy a regular one, you can go to Wuhan Rongcheng Technology that telescope ** to see, how to say that it is still the most important thing in your body, not to mention whether there are materials, and the materials are not standardized, it is very difficult to make alone, it is a fine job, otherwise why would the telescope sell so expensive.
Summary. Hello! When choosing a good astronomical telescope, there are several factors to consider: >>>More
1. Theoretically, each has its own strengths. None of them are exceptional. >>>More
There are three types of astronomical telescopes: refractive, reflective, and reentent. Among them, the achromatic refractive telescope under the refractive classification is more suitable for family and personal entry. >>>More
