![]() The mirror is easier to manufacture than a lens, so they are cheaper than refractors.Reflecting telescopes are available in gig apertures.Because of the small aperture, they can’t collect enough light to enjoy observing deep-sky objects like nebulae and galaxies.High-quality refractors with compound lenses are very expensive.A compound lens is correcting this issue resulting in a higher price of the telescope. Chromatic Aberration – “color fringing” is a problem with the lenses where they can’t focus all colors to a one-point.Refracting telescopes are available only with small apertures.A Refracting telescope is an excellent choice to observe the moon and planets.Temperature change doesn’t affect the stargazing experience because of the closed tube design.Refractors with complex lens designs are the number one choice for astrophotography.Refracting telescope is a good choice for kids.Refracting telescopes are easy to use and require little to no maintenance.Mirrors reflect the light to create an image in the eyepiece that’s why it is called a reflecting telescope. ![]() The secondary mirror is tilted 45 degrees and reflects the light into the eyepiece on the side of the tube. The tube is open, the light goes through and reflects from the primary mirror to a small flat secondary mirror at the front of the telescope. Reflecting telescope uses a spherical or parabolic primary mirror at the end of the telescope tube. ![]() The only lens in the reflecting telescope is the eyepiece. This design uses mirrors to produce an image. The reflecting telescope is also called the Newtonian telescope because it uses the Newtonian design. Galilean Refractor design is more like a spying glass, and it is not used in the modern refracting telescopes. This design is producing a true image that is not inverted. Galilean Refractor design is using a convex lens and concave lens in the eyepiece, but the eyepiece is placed before the focus point of the primary lens. This design allows for a more significant apparent field of view in the eyepiece and a longer focal length telescope to achieve higher magnification. The light is refracted in the primary lens and produces a magnifying image in the eyepiece, hence called “Refracting” telescope.īecause the eyepiece is situated behind the primary lens’s focal plane, the eyepiece’s image is inverted both vertically and horizontally. The Keplerian Refracting telescope uses a convex lens at the front and a convex lens inside the eyepiece at the back of the telescope behind the primary lens’s focus point. Modern refracting telescopes are using Keplerian Refractor design. These telescopes are using only lenses to magnify the distant object. Refracting telescopes are very common telescopes used by amateur astronomers. If you want to learn more about the other designs, you can read my article Schmidt Cassegrain vs. There are also other telescope designs like Schmidt Cassegrain and Maksutov Cassegrain telescope, but in this article, I will only talk about Refractor vs. Refractor telescopes usually have smaller apertures and are more expensive than reflector telescopes. The refractor telescope requires less maintenance than a reflector telescope. The difference is also in the maintenance required between those two. The main difference between refractor and reflector telescope is that the refractor uses optical lenses, and the reflector telescope uses mirrors. That is a huge mistake because there are big differences between refracting and reflecting telescopes. Many people buying the first telescope are making the decision based on the look of the telescope. The main telescope designs you can choose from are the refractor telescope and reflector telescope. If you are looking to buy your first telescope, you will find out that there are a few types of telescope designs. I may receive a commission for purchases made through these links.
