As an expert in the field of astronomy, I can tell you that the telescope is one of the most crucial tools for observing and studying celestial objects. It has been instrumental in our understanding of the universe and has led to many significant discoveries. Here's a detailed look at the function of the telescope:
Light Gathering
The first and foremost function of a telescope is its ability to gather light. The universe is vast and the light from distant objects is often very faint by the time it reaches Earth. Telescopes, particularly those with large apertures, are capable of collecting a significant amount of this light, which allows astronomers to study objects that would otherwise be invisible to the naked eye. This is particularly important for observing dim or distant objects like galaxies, nebulae, and quasars.
Resolution
The second key function of a telescope is its resolution, which refers to its ability to distinguish between two closely spaced objects. The resolution of a telescope is directly related to the size of its aperture. The larger the aperture, the better the resolution. This is because the larger the aperture, the more light a telescope can collect, and the finer the details it can reveal. High resolution is crucial for studying the surface features of planets, the structure of star clusters, and the details of distant galaxies.
Magnification
The third main function of a telescope is magnification. This is the process of making distant objects appear larger. The magnification of a telescope is determined by the ratio of the telescope's focal length to the eyepiece's focal length. The higher the magnification, the larger the object will appear. However, it's important to note that simply increasing magnification does not necessarily improve the image quality. In fact, if a telescope is magnified beyond its capacity, the image can become distorted and less clear.
In addition to these three main functions, telescopes also have other important features. For example, they often come equipped with various filters that can enhance the visibility of certain types of celestial objects. They may also have tracking systems that allow them to follow the motion of celestial objects across the sky.
In conclusion, the telescope is a powerful tool that has greatly expanded our understanding of the universe. Its ability to gather light, resolve fine details, and magnify distant objects has led to countless discoveries and continues to be an essential part of astronomical research.

The main purpose of astronomical telescope is to make objects from outer space appear as bright, contrasty and large as possible. That defines its three main function: light gathering, resolution and magnification.
