The terrestrial telescopes have one more additional convex lens (erecting lens), placed between the objective and the eyepiece, to make the final image erect. This erecting lens is not required in the astronomical telescope as the celestial objects that are viewed using a astronomical telescope are spherical in shape, so it does not matter whether the final image is inverted or erect.
