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. The lowest price can be bought around 500 yuan, like Xingtelang 60AZ. Because the aperture is relatively small, it is suitable for observing a single planet and details. Reflective type is relatively short, with good imaging effect, no chromatic aberration, large aperture and large viewing field, which is suitable for observing a large area of starry sky. But it needs to be painted every three to five years. There is no refractive convenience in maintenance.

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.

You can go to the knowledge area of the galaxy telescope. Just search Baidu for "Galaxy Telescope", which contains a lot of knowledge about the selection, maintenance and use of telescopes. At present, many telescopes are on sale and there are gifts.
