Following are the advantages of a reflecting type telescope over a refracting type of telescope –
Due to the large aperture of the mirror used in the reflecting telescopes, it has high resolving power.
The reflecting type of telescope is free from chromatic aberration (formation of the coloured image of a white object).
The use of paraboloidal mirrors reduces spherical aberration (formation of a nonpoint, blurred image of a point object).
The image formed by a reflecting telescope is brighter than a refracting telescope.
