Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
Refracting telescopes tend to be more top heavy than reflecting telescopes because the lens at the front of the telescope, which is used to gather light, can be heavier than the mirrors used in reflecting telescopes. This imbalance can make refracting telescopes more prone to tipping if not properly balanced or supported.
A refracting telescope uses lenses to gather and focus light, while a reflecting telescope uses mirrors. Reflecting telescopes are often preferred for large astronomical telescopes because mirrors can be made larger and more easily than lenses.
Hi , A reflective scope uses mirrors to focus the image and the light while a refractive scope uses curved glass lenses to focus the light and the image. Generally the reflector telescope is better for deep sky viewing and the refractor is better for lunar and planetary viewing. You can also find a compound telescope which uses both glass and mirrors which is better for general viewing.

Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera. Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is. Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope. The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.
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.

If you are comparing the biggest telescopes in each type, that's because a large refracting telescope needs a huge lens, which gets expensive; also, the lens can't be supported, while a mirror can.
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.

Ah, a refracting telescope is a wonderful invention! It works by using a lens to bend or refract light, helping us see objects in the distance with more clarity. Unlike other types of telescopes, like reflectors or catadioptrics, refracting telescopes use lenses instead of mirrors to gather and focus light. Remember, there's no right or wrong choice when it comes to telescopes – each one has its unique beauty and purpose!
The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.
A reflecting telescope has both magnifying mirrors and lenses to focus the image on the eyepiece. A refracting telescope uses only lenses to magnify and focus. A reflecting telescope can be much smaller, because the light can travel through the barrel of the telescope several times, being magnified with each reflection. This is why most large modern telescopes are reflectors.
