\\ \text{Magnification of a telescope is given by:} \\ M=\frac{\theta_{i}}{\theta_{o}}$ \\ $20=\frac{h / d_{i}}{h / d_{o}}$ \\ $20=\frac{d_{o}}{d_{i}}$ \\ Distance of image, $d_{i}=\frac{d_{o}}{20}$

Telescope resolves and brings the object closer which is far away from the telescope. Hence for telescope with magnifying power 20, the free appears 20 times nearer.
