Telescope Terms To Know: 

Diagonal:

 A mirror that deflects the ray of light 90 degrees. 

With a horizontal telescope 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). 

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 used to determine magnification. 

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).
