Allows you to gather more light from a distant object.
A telescope can do that, but magnification is not its purpose.
The least important power of a telescope is likely the magnification power. While magnification allows you to zoom in on objects, other factors such as aperture size, optical quality, and clarity are more crucial for obtaining clear and detailed images.
Although I'm not familiar with the Nikon P900 system, adding a camera to a telescope is usually an enhancement. The only downside would be if you are trying to exceed the usable magnification of the overall system. Despite manufacturers claims of high magnification (for sales purposes), no telescope is much good above 100 power, and excellent images are usually achieved around 60x. High magnification means magnifying the atmospheric and optical defects as well as the image you want.
Increasing the resolution or magnification of the optical instrument, such as a microscope or telescope, will allow you to see more details of the object.
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
"Optical", in this case, simply means that they work with light.
The formula for calculating the angular magnification of a telescope is: Magnification focal length of the objective lens / focal length of the eyepiece.
Magnification in optical systems is calculated by dividing the size of the image produced by the lens by the size of the object being viewed. This ratio gives the magnification factor of the optical system.
The magnification. What really matters about a telescope, the single most important piece of information, is the diameter of the main lens, or main mirror.The magnification.

The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.
No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
