a telescope's magnification is calculated as the ratio of the focal length of the primary objective to the focal length of the eyepiece. Since a telescope is defined by the primary objective, this part of it is essentially unchangeable. Therefore, the way to increase magnification is to decrease the focal length of the eyepiece. For example, a 1000mm objective and a 25mm eyepiece yields a magnification of (1000/25) 40x. Changing the eyepiece to a 10mm eyepiece increases magnification to (1000/10) 100x.

Which power of a telescope is the least important?
Magnifying Power
What are the 4 properties of a telescope?
I know of at least three. I hope these help: - magnifying power - light gathering power - field of view
If the primary mirror of a telescope have a focal length of 225 centimeters and the eyepiece has a focal length of 7.5 millimeters then what is the magnifying power of the telescope?
The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X
Who invented the second telescope?
Isaac Newton. He made it with a magnifying power of 38 diameters and presented it to the Royal Society of London in December 1672.
What invention helped Galileo to prove that Copernicus was correct?
The telescope, especially for astronomical observation. He got a toy from the carnival. and made it into a telescope by putting in a magnifying glass in it.
