The diameter of the concave mirror.
Isaac Newton invented the reflecting telescope.
The cost of a reflecting telescope can vary greatly depending on the size, brand, and quality of the telescope. Entry-level reflecting telescopes can start at around $200, while more advanced models can cost several thousand dollars or more.
The reflecting telescope
A reflector telescope collects light with a mirror. The mirror is located at the back of the telescope and reflects the incoming light to a focal point where it is then collected by an eyepiece for viewing.
One end of a reflecting telescope is the big hole pointed at the star. The other end of the reflecting telescope has a lens called an eyepiece.
Isaac Newton invented the reflecting telescope.
Refracting
It is a reflecting telescope
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
A Reflecting telescope has a lot of zooming technologies and the High Power telescope is highly powered.

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.
Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
Those are, in fact, identical down to the finest detail.
