Before buying a telescope, you must let your child understand the knowledge of the telescope, after understanding the knowledge of the telescope, you can buy some telescope parts DIY, so that the child's interest in this area will not decline, but also exercise their brain, I think I just bought a 300-degree reading glasses, made a telescope, the lens barrel is 3 meters.
Today's telescopes can't meet the needs of astronomy at all, at most they observe the starry sky, and now the so-called [astronomical enthusiasts] are basically starry sky lovers, just looking at the starry sky.
If your child is also a lover of the stars, then a reading glasses will do the trick; If you are determined to learn astronomy, you need to buy the [Active Star Map].

Hello, I'm in the optical industry. In fact, I don't think it's advisable to choose an astronomical telescope unless your child is really into astronomy.
Astronomical telescopes, many people buy them back, and they are idle for a few days.
If possible, it is recommended to actually contact it first, and if you really have a hobby, then it is not too late to spend money to buy it.
You can take a look.
Click on "Telescope Knowledge and Introduction" - there is a "Common Sense and Identification" in it, which includes an introduction to astronomical knowledge.
There is a little introduction to the later part of the introduction, which introduces the things about astronomical telescopes. I still recommend that you touch the real thing first and then decide if it's astronomical or not. I think that's very important.

If you don't have a lot of observation experience, you don't need to buy a very good telescope, there is no absolute difference between good and bad telescopes, only the technology of the observer.
The main targets of general observation are the moon and planets, such as Zhejiang Phoenix 76700 or 76900 can be satisfied, these two telescopes are not very professional but more economical, slightly professional can buy Boguan Pioneer 60700, 70900, 80800 and so on. But **slightly more expensive.
These are more suitable for beginners.

Don't buy Phoenix's, it has a bad reputation. You can consider Boguan's Pioneer 70 900, **less than 1000 yuan, the accessories are relatively complete, and the observation effect is also acceptable. In addition, I need to explain to you that astronomical telescopes belong to precision equipment, even if it is an entry-level telescope with general observation effect, its ** will not be too low, there are many telescopes on the market, these are not bought, and it will cost money to buy.

It's better to buy a binocular first, if the child is not a three-minute heat, you can consider buying an astronomical telescope, if yes, you can buy binoculars to avoid regretting after buying. 12-year-old children, using astronomical telescopes may have some impact on height, people are not as tall as mirrors, and they are white.

The nth time to answer this kind of question, novices or buy an astronomical telescope within 1000 yuan to practice, you can look at the wolf in China, if you want to be better, use Xingtreng, bresser, reflective personal think it is better, but also remember to add Bard membrane in front of the objective lens before looking at the sun.

Beijing Galaxy Telescope Answer:
The gap between astronomical telescopes is very large, and our ordinary junior astronomy enthusiasts can choose non-professional mirrors (professional mirrors are very expensive, and they are generally used for professional observation). **In the 1000-2000 yuan or so low-end astronomical telescope can be, of course, if you are very passionate about astronomy, for the observation effect of high requirements, you must choose the high-end telescope, refraction and reflection have their own advantages and disadvantages, mainly depending on what you want to observe, choose the best one for yourself;
The refractive aperture is relatively small, the focal length is relatively long, and the realization multiple is relatively high, which is more suitable for seeing the single planet and details, but it is easy to maintain, simple to operate, and the low-end refractor is relatively cheap, which is more suitable for beginners.
The reflective type has a large aperture, a short focal length, and a relatively low realization multiple, which is more suitable for seeing a large area of the starry sky, with a large observation field of view, and no chromatic aberration, but it needs to be coated once every five years.
The realization multiples mentioned above are relatively speaking, the magnification of astronomical telescopes is directly related to the eyepieces, and the eyepieces that are standard with each model are different and cannot be generalized. For beginner astronomy enthusiasts, it is still recommended to choose the refractive type.
For entry-level astronomical telescopes, the Centron 90EQ (refractive type) and 130EQ (reflective type) are both good choices.
90EQ This can see the crater on the surface of the moon, can see the Hui Duan to Saturn, Jupiter, Jupiter moons, etc., you can also view the scenery, you can see the trademark of one or two kilometers of air conditioning, this basic configuration is very good, and the imaging effect is also great, ** at about 1600 yuan.
130EQ can see the craters on the surface of the moon, Saturn's rings, Jupiter, Jupiter's cloud belts, Jupiter's moons, etc., and 130EQ is basically a civilian astronomical telescope that can shoot nebulae with the lowest aperture requirements after being connected to the camera. **Around 1500 RMB. The relative aperture of 130EQ is large, and the observation field is large.
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.
It is important to know that astrophotography with a telescope is never a matter of clicking on the eyepiece. The first way to shoot is to use a CCD or SLR to unscrew the lens and connect it to Tianwang, and then shoot a single frame or **, and carry out various post-processing on the computer. >>>More
