The magnifying power of a telescope equals the focal length of the eyepiece divided by the focal length of the objective of the telescope.

Explanation:

Magnifying power of a telescope

The value of the magnifying power of a telescope can be easily determined by dividing objective lens or mirror's focal length by the eyepiece focal length value.

Hence,

Magnifying power of telescope = focal length of lens / focal length of the eyepiece.

According to the above formula,

To have a high value of magnification of the telescope, the focal length of the lens should be higher than the focal length of the eyepiece.
