What is the essential difference between a terrestrial telescope and an astronomical telescope ?

Astronomical Telescope

The eye-piece of an astronomical telescope has focal length of 10 cm. The telescope is focused for normal vision of distant objects when the tube length is 1.0 m. Find the focal length of the objective and the magnifying power of the telescope.

Assuming the mean wavelength of light as 555 nm , estimate the smallest angular separation of two stars which can be just resolved by the telescope. Given the diameter of objective of astronomical telescope is 25 cm .
