It is not subjected to chromatic aberrations.It has a shorter tube than a refracting telescope.Since the mirrors are cheaper to manufacture than optical lenses, thus this telescope is cheaper.
Observing bright distant celestial bodies in space.įor a better understanding of the difference between reflector and refractor telescopes, let’s have a look at the advantages and disadvantages of the two types. Observing deep distant objects in the space. For the Gallelian refracting telescope, one is convex while the other is concave. Typically two optical lenses.For Kaplarian refracting telescope, both are convex. In Newtonian design, the primary mirror is concave, while the second one is a diagonal mirror. Reflector vs Refractor TelescopeĪ single mirror or combination of mirrors. For that purpose, let’s observe the reflector vs refractor telescope comparison table. We know what is reflecting and refracting telescopes thus, now we will study the difference between reflector and refractor telescopes. The Galilean design, due to some inaccuracy, has been replaced by the Keplerian design. He assembled a concave and a convex lens in a long tube, proving the first structure for a refracting telescope.
The image produced by a Keplerian refractor telescope is inverted both horizontally and vertically.
The light gets refracted at the objective and produces a magnified image at the eyepiece, through which the observer can study the image. The eyepiece is situated behind the focus point of the objective lens. The lens at the front is called the objective, while at the end is the eyepiece. A Keplerian refracting telescope uses a pair of convex lenses. The design used for refracting telescopes these days is the Keplerian Refractor design. Its lens has a small aperture and is best known for creating sharp and magnified images. It is best known for observing bright celestial bodies in outer space, such as planets, stars, and the moon. Unlike a reflecting telescope, a refracting telescope uses an arrangement of lenses to produce a more precise and nearer image of faraway objects.

Still today, the Newtonian design is preferred and considered best for a reflecting telescope. He used a concave mirror (primary) and a diagonal mirror (secondary) for his design. In 1668, Isaac Newton invented it while solving the problem of chromatic aberrations in a refracting telescope. The picture produced by a Newtonian reflecting telescope is inverted. The eyepiece is a lens through which the viewer can see the magnified picture. This focused light reaches the secondary mirror, which is tilted at a 45-degree angle so that the light from this mirror is reflected in the eyepiece. It catches light from distant bright bodies and focuses it on a point. This curved mirror can be parabolic or spherical. At the bottom of the tube, a curved mirror, also called a primary mirror, is present. The design mostly used these days for a reflector is the Newtonian design thus, it is also named as a Newtonian reflector. It has huge mirrors that can capture a good amount of light and create enlarged images of obscure objects.
A reflector telescope is basically known for capturing faint and dim lights from distant objects and make those objects appear magnified. A reflecting telescope is preferred for observing deep objects like nebulae in space.
