`M = (F_p/F_e)`

12.5

The Magnification of a Telescope calculator compute the magnification of a telescope based on the focal lengths of the primary mirror or lens and the eyepiece.

INSTRUCTIONS: Choose units and enter the following:

• (F_p) This is the focal length of the primary lens or mirror.
• (F_e) This is the focal length of the eyepiece.

Magnification: The calculator return the magnification of the telescope.

General Information

The magnification power M of a telescope is the ratio of the focal length of the primary lens or mirror F_P divided by the focal length of the eyepiece F_e.
