Focal length on a telescope
Did you know?
WebThe focal length of a telescope is the distance between the primary lens/ mirror and the point where the image is in focus. To determine the magnification of a telescope for a given eyepiece, all you have to do is divide the focal length of the telescope by the focal length of the eyepiece. Thus, consider using an eyepiece with a 10mm focal length. http://physics.wm.edu/~labs/astro/astro_manual/ch8.pdf
