Eyepiece (5):

An eyepiece is a system made for your eye and comprised of one or more lenses. In an

eyepiece, the clear image that is generated in the focal point of a lens is captured and

magnied still more. There is a simple formula for calculating the magnication: Focal

length of the telescope tube / Focal length of the eyepiece = Magnication In a tele-

scope, the magnication depends on both the focal length of the telescope tube and

the focal length of the eyepiece. From this formula, we see that if you use an eyepiece

with a focal length of 20 mm and a telescope tube with a focal length of 400 mm, you

will get the following magnication: 400 mm / 20 mm = 20 times magnication

Magnication:

The magnication corresponds to the difference between observation with the naked eye and observation through

a magnifying device like a telescope. If a telescope conguration has a magnication of 30x, then an object

viewed through the telescope will appear 30 times larger than it would with the naked eye. See also 'Eyepiece'.
