What does the magnification of a telescope refer to?

The magnification of a binoculars refers to the ability of the binoculars to bring objects closer. For example, when observing an object with a 7x binoculars, the effect of observing an object 700 meters away through the binoculars is similar to that of observing an object 100 meters away with the naked eye (of course, the effect is somewhat worse due to environmental influences).

Many people always believe that the higher the magnification, the better. Some dealers and manufacturers also attract and deceive consumers with false high magnifications. There are even some binoculars on the market that are labeled as 990x! In fact, the reasonable magnification of a binoculars is related to the aperture of the telescope and the observation method: the larger the aperture, the higher the magnification can be. Binoculars with a stand can have a higher magnification than those held by hand. The higher the magnification, the worse the stability, the smaller and darker the field of view, and the greater the increase in shaking. The influence of breath airflow and air fluctuations on it also increases. For binoculars used for handheld observation, a magnification between 7x and 10x is most suitable, and it is best not to exceed 12x. If the magnification of a binoculars exceeds 12x, handheld observation will be very inconvenient.

Military binoculars used in countries around the world are mostly in the range of 6x to 10x. For example, the main magnifications of military telescopes in our country are 7x and 8x, because clear and stable imaging is very important.
