Refractor vs Reflector Telescope

Refractors use lenses and need almost no maintenance. Reflectors use mirrors and give much more aperture for the same money.

Choose Refractor if

  • You want grab-and-go simplicity
  • You mostly view the Moon and planets
  • You also want terrestrial viewing

Choose Reflector if

  • You want the most aperture for your budget
  • Deep-sky objects are the goal
  • You do not mind occasional collimation

The bottom line

For visual observing on a budget a reflector, especially a Dobsonian, shows the most. A small refractor is the easiest telescope to own and use often.
