What kind of telescope do you choose?

Beijing Xinghe Telescope answers for you: I don't know whether you want to choose binoculars or astronomical telescopes. The brand of binocular tube wave is good, AstraZeneca can be considered in astronomy. The following are some points for attention when choosing binoculars and astronomy. Please refer to: the selection of two parameters of binoculars is very important. One is a multiple of the aperture, such as 7*50 or 8*42. One: multiple: the number before the asterisk (*) is a multiple. For ordinary binoculars, the multiple is more than 7- 10, generally not more than 65438. 2. Aperture: Ampere behind the asterisk (*) is of large caliber, with large observation field, high brightness and high comfort. If you want to observe a large area, it is recommended to choose a large caliber, but it is relatively large. Three: the ratio of aperture to multiple: the ratio of 7 aperture to 50 is relatively high for observation comfort, but if you like high-magnification observation, you can choose 10 times. At present, Guanbo is relatively good among domestic brands, especially double-tube ones, with many series and models. Between 300 and 500 yuan, Hunter 7*50 is a better choice, and the price is around 400 yuan. Astronomical telescopes can be divided into three types according to the imaging principle: refractive, reflective and catadioptric. For beginners, refraction is the best choice. The operation and maintenance are very convenient and simple, and the price is relatively cheap. You can buy it as low as 500 yuan. The reflection type is short, the imaging effect is good, and there is no color difference. The aperture can be larger and the observation field is larger, but the price is higher. For the entry-level astronomical telescope, Xingzhuang 80EQ and 130EQ are both better choices. 80EQ, you can see craters on the surface of the moon, Saturn, Jupiter and Jupiter's satellites. You can also see the scenery and the trademark of air conditioner for one or two kilometers. The price is around 850 yuan. 130EQ You can see craters, Saturn's rings, Jupiter, nebulae and Jupiter's moons on the surface of the moon. At the same time, 130EQ is basically a civil astronomical telescope, which can shoot nebulae with minimum aperture requirements after connecting a camera. The price is around 1500 yuan. 130EQ has a large relative aperture and a large observation field. You can go to the knowledge area of Galaxy Telescope and search for "Galaxy Telescope" in Baidu, which contains a lot of knowledge about telescope purchase, maintenance and use.
