The telescope is a device that is used to see distant objects. It has two main elements objective and eyepiece. Here, the objective is nothing but a mirror or lens and an eyepiece is a set of lenses that corrects the beam direction.
The important thing is that the telescope objective collects the light from the aperture and processes it through the smaller surface of the eyepiece. The quantity of light that enters, exit the telescope is equal so the image is not only magnified but also its brightness increases significantly.
The maginification of teleascope formula is given by
M = fo / fe
fo is the objective focal length
fe is eyepiece focal length
M is the image maginification
We can say that the magnification of the telescope increases when the focal length of the object increases or when the eyepiece focal length decreases.
Telescope Parameters for Magnification
The parameters of the adjusting telescope are along the lines:
Question: What is the angular magnification of a telescope that has a 100 cm focal length objective and a 2.50 cm focal length eyepiece?
The focal length of objective lens = 100 cm
The focal length of the eyepiece = 2.50 cm
The maginification of a telescope equation M = fo/fe
Therefore, the angular magnification of the telescope is 40.

1. How to calculate the magnification of a telescope?
To calculate the magnification of a telescope easily use our free Telescope Magnification calculator. Enter the inputs such as the diameter of the objective f-ratio, the focal length of the eyepiece, resolving power, score field of view and surface brightness details and tap the calculate button. You will get the magnification and star magnitude limit as output within seconds.
2. What is the formula for magnification?
Magnification is the ratio of objective focal length to the focal length of eyepiece. So, its formula is Telescope Magnificatiom M = fo / fe.
3. What is the Telescope Magnification?
Magnification is the measure of how much a telescope magnifies the image of the object. The two types of magnification are linear magnification and angular magnification. Both are used to measure optical instrument magnification and it is denoted by the letter M.
4. What does negative magnification mean?
The negative magnification means the object is inverted.
