Magnification of Terrestrial Telescope #8211; (a) For relaxed eye, M<sub>∞</sub> = f<sub>0</sub>/f<sub>e</sub> In this position, length of telescope L<sub>∞</sub> = f<sub>0</sub> + 4f + f<sub>e</sub> (b) When a final image is formed at least distance of distinct vision, M<sub>0</sub> = f<sub>0</sub>/f<sub>e</sub> (1 + f<sub>e</sub>/D) Length of telescope, L<sub>∞</sub> = f<sub>0</sub> + 4f + u<sub>e</sub> f<sub>0</sub> = Focal length of objective lens f<sub>e</sub> = Focal length of eyepiece
