Telescope ABC's
What do the following terms mean?
Eyepiece (3): 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 magnified still
more. There is a simple formula for calculating the magnification:
Focal length of the telescope tube / Focal length of the eyepiece = Magnification
In a telescope, the magnification 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 600 mm, you will get the following magnification:
600 mm / 20 mm = 30 times magnification
Focal length: Everything that magnifies an object via an optic (lens) has a certain focal length. The focal
length is the length of the path the light travels from the surface of the lens to its focal point. The focal
point is also referred to as the focus. In focus, the image is clear. In the case of a telescope, the focal
length of the telescope tube and the eyepieces are combined.
Lens: The lens turns the light that falls on it around in such a way so that the light gives a clear image in
the focal point after it has traveled a certain distance (focal length).
The magnification corresponds to the difference between observation with the naked eye and
Magnification:
observation through a magnifying device like a telescope. If a telescope configuration has a magnification of
30x, then an object viewed through the telescope will appear 30 times larger than it would with the naked eye.
See also 'Eyepiece'.
Zenith mirror (diagonal) (2): A mirror that deflects the ray of light 90 degrees. With a horizontal tel-
escope tube, this device deflects the light upwards so that you can comfortably observe by looking
downwards into the eyepiece. The image in a diagonal mirror appears upright, but rotated around its
vertical axis (mirror image).
DISPOSAL
Dispose of the packaging materials properly, according to their type, such as paper or card-
board. Contact your local waste-disposal service or environmental authority for information on
the proper disposal.
Please take the current legal regulations into account when disposing of your device. You can get
more information on the proper disposal from your local waste-disposal service or environmental au-
thority.
