Which is better refractor or Newtonian?
Refractors are more rugged, and more easily adapted to photography. Less expensive (achromatic) refractors suffer from varying degrees of chromatic aberration, which causes colored fringes and halos around bright objects. Newtonian reflectors have a huge cost advantage.
Was Galileo’s telescope refracting or reflecting?
Galileo Galilei’s discovered the Galilean satellites of Jupiter in 1610 with a refracting telescope.
Do astronomers use reflecting or refracting telescopes?
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.

Is the Hubble Space Telescope refracting or reflecting?
reflecting telescope
The Hubble Space Telescope is a reflecting telescope. Even though Newton invented the reflecting telescope to study what he knew about light, by 1730 astronomers were using it to study the Universe. They found that the bigger the mirror, the more light it reflected.
What was wrong with Galileo’s telescope?
The spyglass-turned-telescope had limitations, some of which Galileo was able to design around. To reduce distortions such as elongations and blurriness caused by the curvature of the “objective” lens—the convex lens at the far end of the telescope—Galileo ground a lens larger than he needed, for example.
Why reflecting telescopes are 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.
