All of the following statements are correct except

Choose an answer

The total focal length of astronomical telescope is the sum of the focal lengths of its two lenses

The image formed by the astronomical telescope is always erect because the effect of the combination of the two lenses is divergent

The magnification of an astronomical telescope can increases by decreasing the focal length of the eyepiece

The magnifying power of the refracting type of astronomical telescope is the ratio of the focal length of the objective to that of the eye piece
