text: Generally expressed, focal length is the distance (given in millimeters) between the telescope's primary lens or mirror and the point where the light rays come together in focus.
text: Focal length is the distance that the primary mirror uses to bring the light to focus.
text: Eyepiece focal length is the distance from the entrance of the eyepiece (where the parallel rays of light begin to converge) to its focal point.
text: -The focal length of a telescope is the distance from the objective lens or mirror at which the light comes to focus.
text: focal length is the distance that the light in the telescope travels from the objective lens or mirror to the point where that light reaches focus (the focal plane).
text: Every scope has a focal length, which is effectively the distance from the primary lens or mirror to the image it forms.
