Which astronomical telescope should I buy to watch the stars at home?

Beginners can get started at home, and ordinary stargazers can choose 7X50 binoculars, which is easy to carry. For better conditions, it is recommended to choose 60 mm, 70 mm and 80 mm refractors:

First of all, it is easy to carry, use and maintain, and can be often taken out for observation (100mm is relatively overweight and inconvenient to carry; How much depends on the number of observations rather than the diameter of the telescope);

Secondly, even in cities with severe light damage, you can see sunspots, the moon and bright celestial bodies such as Jupiter and Saturn.

In addition, the price is low. If you buy a bigger and better telescope in the future, you can upgrade it as a star guide and make full use of it.

Astronomical telescope is an important tool for observing celestial bodies. It is no exaggeration to say that there would be no modern astronomy without the birth and development of telescopes. With the improvement of telescope performance in all aspects, astronomy is also experiencing a huge leap, which rapidly promotes human understanding of the universe.

Generally, an astronomical telescope has two lens barrels. The big one is the main mirror, which is used to observe the target. The small one is called an image finder, which is used to find the target. It is also called a sight. The eyepiece is an individual and determines the magnification. There will be an f value on the eyepiece, which is the focal length of the eyepiece. Divide the f value of the primary mirror by the f value of the currently used eyepiece, which is the current magnification. Remember, magnification is the standard. The limit magnification of a telescope with a diameter of 6 cm is about 120 times, and the maximum magnification of 8 cm is about 160 times. If it exceeds this range, the object cannot be seen clearly.
