Refractive aperture is relatively small, focal length is relatively long, and the realization multiple is relatively high, which is more suitable for seeing a single planet and details, but it is convenient to maintain and simple to operate. Low-end refractors are relatively cheaper and more suitable for novices.
Reflective type has the advantages of large aperture, short focal length and relatively low magnification, which is more suitable for viewing a large area of starry sky, with large viewing field and no chromatic aberration, but it needs to be painted once every five years.
The realization multiple mentioned above is relative. The magnification of an astronomical telescope is directly related to the eyepiece. Every standard eyepiece is different and cannot be generalized. For beginners, it is still recommended to choose refraction.
For entry-level astronomical telescopes, Startron 80EQ (refractive) and 130EQ (reflective) 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 see the trademark of the air conditioner one or two kilometers away. 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.
The above comes from/links? Url = dkne9d-rkzamqd _ n015vqizvqvsycliwsdzrtwspix6bxxxct2mon1dmuxl1jbtu2pxe6yn0d8phbslfnhv9 _. Although the original text is suspected of advertising, I personally think this answer is more pertinent. There are two other suggestions:
One is to figure out what you want to do. If we simply observe the craters on the moon, we will find that ordinary binoculars can also see the general picture. Moreover, to shoot deep space, you have to be equipped with a SLR camera, an equatorial telescope and a star guide. It is best to have a systematic study of basic astronomical knowledge first. If you really don't have time, at least you can learn some basic astronomical information, such as the planetary characteristics of the solar system, Hou Yu Xiongqin, messier catalog and so on. And pay attention to the prediction of these astronomical phenomena, such as meteor and comet occultation, solar eclipse and sunspot in Ling Xing. Only by understanding these things can you know what you are looking at, otherwise there will only be a simple visual impact and it will be easy to lose interest after a long time.
The second is to look at the city where you live. . . You know, I am in Beijing. Clear skies with good atmospheric conditions are rare, and it is not romantic to look at the stars with an index of three or four hundred. Therefore, when considering the cost performance of equipment, we must also consider this point. But now players with better conditions will choose to drive to the suburbs of Beijing to observe or shoot, or go further to places with good scenery, good air and less light pollution all over the country, and even have friends who chase the total solar eclipse, aurora and run around the world. It's very chic. It depends on your financial and time conditions.
