What are the similarities and differences between a reflecting telescope and a refracting telescope?
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.
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.
What are the disadvantages of a reflecting telescope?
Disadvantages. It is easy to get the optics out of alignment. A reflector telescope’s tube is open to the outside and the optics need frequent cleaning. Often a secondary mirror is used to redirect the light into a more convenient viewing spot.
What are the disadvantages of a refracting 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.
