A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
The telescope is cylindrical. Its primary mirror is concave.

A telescope that uses one or more mirrors is called a reflecting telescope. Light is collected and focused by the primary mirror, which then reflects it to a secondary mirror that directs it to the eyepiece or detector. This design allows for larger apertures and better image quality compared to refracting telescopes.

A hole at one end, a mirror at the other.
A parabolic mirror, usually. A spherical mirror is also sometimes used, but that requires additional corrections in other parts of the telescope.

A reflecting telescope.
To find the aperture of a reflecting telescope, you would measure the diameter of the primary mirror. The aperture of a telescope is the diameter of its primary light-gathering element, which in the case of a reflecting telescope, is the primary mirror.

A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
