This is the most common type of reflecting type telescope called Cassegrain Telescope.
The unusual feature about this telescope is that it instead of using lens for focussing the rays it uses a concave mirror and hence the name.
Its most important drawback was its secondary mirror in the middle of the tube infront of primary mirror. It reduces the rays incident on the primary and hence reducing the intensity of image formed many times.
