What kind of telescope should beginners choose?

My suggestion is 70/900 packs of EM9 equatorial telescope.

The reasons are as follows

1。 The caliber and price of this mirror are within the acceptable range of novices.

2。 The quality of tube wave mirror is very good.

3。 Guanbo has many service points and convenient after-sales service.

Recommend this post, it is worth reading.

First of all, I am not a senior astronomy enthusiast. Please correct me if there is anything wrong with the following:

I want to talk to you about the principle of buying binoculars:

1, don't blindly seek big. Large-aperture telescopes have no dreams, but everything must be done according to one's ability. The resolution of large telescope is higher than that of small telescope, but it is much worse than that of small telescope in heat balance speed and portability. And if the atmosphere in your place is very unstable, even if you buy a big telescope, it will be like a chicken rib. Finally, you will find that a big telescope is not as good as a small mirror in your hand. Because of the shaking of the atmosphere, the image in the high-powered telescope is like water, and the details are not visible at all. Urban lighting pollution is serious, and all kinds of air pollution are becoming more and more serious. You have to take your telescope to the suburbs to observe. Because large-caliber telescopes do not have the portability of small telescopes, it will be very inconvenient to carry them without a car.

2. Pay attention to the bracket of the telescope. Many colleagues spend a lot of money on the telescope's main mirror, ignoring the importance of tripod, equatorial plane, theodolite, horizon bracket and other supports. When I used the telescope, I found that the bracket was wobbly and almost impossible to observe. In fact, although the telescope bracket is attached to the telescope, its importance cannot be ignored. Especially when the telescope is in a high-power observation state, the slight shaking makes the field of view deviate from the observation target.

Don't be too ambitious. You must do your best to buy binoculars. At the same time, after buying a telescope, you should always use it, use the equipment at hand thoroughly and "burn it out", give full play to the limit of the equipment in your hand and exercise your observation ability. The author contacted some colleagues who like astronomy at school and found that some colleagues talked eloquently about astronomy, which sometimes made the author gasp in admiration. However, when it comes to observation, even the most basic focus can't be done well. This classmate told me that her mother smashed her five binoculars, and she seemed to be a keen observer. Although the small telescope is not as good as the big one, the various operations are relatively simple. You must fully train the basic skills of aiming at the polar axis, focusing and finding stars in order to give full play to the effectiveness of the small telescope.

4. Beginner observation, close to celestial photography. Astrophotography is a difficult project. Film photography, in particular, requires photographers to be quite skilled in telescope operation. In particular, long-term exposure requires high polar axis accuracy, which is not suitable for beginners to take celestial photography. Celestial photography is not only difficult, but also requires high accuracy of telescopes, especially equatorial telescopes. Of course, ordinary celestial photography can still participate, such as total solar eclipse, star trails, meteor showers and other less difficult celestial photography.

5. Treat the price rationally. Do what you can. It is impossible to have good things at too low a price. I accidentally saw this post on some forums: "If you want to go to celestial photography, please recommend binoculars, and the price is around 500 yuan". It's a pity that 500 yuan, astrophotography can only buy middle-distance eyepieces. It can be seen that the price of telescope is very high. Moreover, when crossing the road, I quote a very good saying, "A telescope is worth a penny, a dime is worth two cents, and a dollar is worth three cents." The larger the aperture of the telescope, the higher the price, and it rises geometrically. If you have no money, you'd better buy domestic products that are relatively cheap and have a larger caliber. At the same time, don't believe in ultra-low prices. Too low a low price means the low quality of this geometric multiple.

6. Suggestions for "student soldiers". At present, most fans in China are student soldiers. An obvious feature of student soldiers is that they like to follow the trend and are not calm in doing things. I didn't recognize all the constellations, so I started to buy binoculars. I especially like large caliber. As a result, I bought some large-caliber ones because I had no money, but the accuracy of brackets and lenses was poor, but it was not worth it. For example, the common 76700 Lida brand on the market has obvious spherical aberration and imaging circle. It can be said that the telescope is not worth this ultra-low price. If you don't have money, do ordinary observation diligently and learn from Meng Huan. Maybe you can find comets with the naked eye and read more books. I'm tired of watching popular science. Let's have something a little more professional and take part in the astronomical Olympics. Maybe Harvard takes a fancy to you, so I won't have no money to buy binoculars in the future.
