To collect visible light emitted / reflected / scattered from a distant body, and increase the apparent size (or at least the intensity) of the image specularly, so that features can be discerned / observed.
The telescope is cylindrical. Its primary mirror is concave.
A reflecting telescope has both an eyepiece lens and a mirror. Light enters the telescope and is reflected off the primary mirror to a secondary mirror, which then directs the light to the eyepiece where it is magnified for viewing.

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.
