Is a reflector or refractor better?
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.
What is the advantage of reflectors over refractors?
Reflecting telescopes have a number of other advantages over refractors. They are not subject to chromatic aberration because reflected light does not disperse according to wavelength. Also, the telescope tube of a reflector is shorter than that of a refractor of the same diameter, which reduces the cost of the tube.
What is the major problem that refractors have that reflectors don’t suffer from?
Refractor telescopes suffer from this separation of light into its component colors. One advantage of the Hubble Space telescope over ground based ones is that: A) it is larger than any Earth-based scopes.
What kind of telescope is best for viewing planets?
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.
Why are reflecting telescopes better than refracting?
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.
What problem do refractor telescopes have that reflectors don t?
Reflectors do not suffer from chromatic aberration like refractors do. Large mirrors need only one optical surface, achromats four surfaces to grind. Large lenses deform under their own weight, but mirrors can be supported.
