Reflecting telescopes have many advantages over refracting telescopes. Mirrors don't cause chromatic aberration and they are easier and cheaper to build large. The are also easier to mount because the back of the mirror can be used to attach to the mount. Reflecting telescopes have a few disadvantages as well.
Disadvantages. All refractors suffer from an effect called chromatic aberration (``color deviation or distortion'') that produces a rainbow of colors around the image.
Refracting Telescopes. Commonly known as refractors, telescopes of this kind are used to examine the visible-light region of the electromagnetic spectrum. Typical uses include viewing the Moon, other objects of the solar system such as Jupiter and Mars, and double stars.
Refracting telescopes. Commonly known as refractors, telescopes of this kind are typically used to examine the Moon, other objects of the solar system such as Jupiter and Mars, and binary stars.
Radio waves have a much longer wavelength than light waves (typically 100,000 times longer) and are therefore less susceptible to interferences caused by imperfections on the reflecting surface and therefore not constructed to the extent of smoothness required for glass mirrors.
If you are interested in astrophotography, purchasing a refractor is a better option because of it's specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
Space telescopes have the advantage of being above the blurring effects of the Earth's atmosphere. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth's atmosphere.
In space, however, telescopes are able to geta clearer shot of everything from exploding stars to other galaxies. Another disadvantage for ground-basedtelescopes is that the Earth's atmosphere absorbs much of the infrared andultraviolet light that passes through it. Space telescopes can detect thesewaves.
Reflecting telescopes use mirrors to gather the light. Refracting telescopes use lenses. There are different kinds of reflectors, but in general the refractors all follow the same basic design.
Both refractor and reflector telescopes are best for viewing planets. A good quality telescope with an aperture of 3.5” to 6” will give a beginner great views.
Radio telescopes detect radio waves coming from space. Although they are usually very large and expensive, these telescopes have an advantage over optical telescopes. They can be used in bad weather because the radio waves are not blocked by clouds as they pass through the atmosphere.
Infrared telescopes detect light that has a longer wavelength than the human eye can see. The main advantage of this is that we can use it to see stuff that we otherwise wouldn't be able to.
Radio telescopes only require small antennas. Radio telescopes have much better resolution than optical telescopes. Radio telescopes do not need a clear sky and are not dependent on weather. Radio telescopes do not need a clear sky and are not dependent on weather.
There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes.
Refracting telescopes use a lens to focus light. The largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century.
To put that in perspective, you can see an object that is over 6,750,000,000,000,000,000 miles from us and yet a small 60mm refractor telescope can view it given clear skies and low light pollution.
Disadvantages. There are some limitations with the Hubble Space Telescope when imaging the Moon due to its sensitivity to light and it cannot image areas in the direction of the Sun. They are exceptionally expensive to build and position in place. Maintenance is difficult.
With space telescopes, Earth's atmosphere is no longer an issue as the telescope is above it. This means that space telescopes can both get clearer images and detect wavelengths that the Earth's atmosphere blocks. Improvements in technology, such as adaptive optics, can mitigate, but it is still an issue nonetheless.
The disadvantages are mainly to do with the hassle of operating in space. It's much more expensive, so you can't have such a large telescope. If things go wrong it's much harder to repair them.
Which of the following is not an advantage that a reflector telescope has over a refractor telescope? a reflector doesn't have to do deal with the twinkling of the stars, as a refractor does.
