Why are reflecting telescopes bigger?

Why are reflecting telescopes bigger?

Because the mirror can be fixed onto a metal plate, reflecting telescopes can be much bigger than refractors.

Are most large telescopes reflecting telescopes?

Larger telescopes can collect more light and so they can study dimmer or more distant objects. The largest optical telescopes in the world today are reflectors.

Are large telescopes reflecting?

Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors.

What are the disadvantages of a reflecting telescope?

Reflecting telescopes have a few disadvantages as well. Because they are normally open, the mirrors have to be cleaned. Also, unless the mirrors and other optics are kept at the same temperature as the outside air, there will be air currents inside the telescope that will cause images to be fuzzy.

What are the disadvantages of telescope?

Disadvantages:

• Very high initial cost relative to reflector.
• A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.
• Long focal ratios can mean that the instrument is cumbersome.

  Should I get a refractor or reflector telescope?

If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.

  Do astronomers use reflecting or refracting telescopes?

  A refractor uses lenses within a tube to refract (bend) light. It’s the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand, use mirrors instead of lenses to reflect light. Most modern observatories use reflectors because their telescopes are so huge.
