Focal length:
Everything that magnies 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 tel-
escope 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).
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'.
Zenith mirror (diagonal) (2):
A mirror that deects the ray of light 90 degrees. With a horizontal telescope tube, this device deects 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).
