ApertureBuy the right telescope, not the biggest one

Instrument class

130 mm tabletop Dobsonian

A short Newtonian on a small rocker box that sits on a table, a wall or a crate. The best value in astronomy at the moment, and the answer to more first-telescope questions than anything else here.

What it does well

  • Real aperture — several hundred times the light of an unaided eye — at a price that does not need justifying
  • Carried outside in one hand, set up in a couple of minutes
  • Nothing to align, nothing to power, nothing to fight in the dark

What it costs you

  • Needs a table or a wall. On the ground you are lying down
  • Needs collimating occasionally — five minutes with a €20 cap
  • The supplied eyepieces are usually adequate rather than good

Fit against each goal

  • Sharing it with children · 5 out of 5

    On a garden table it sits at a child's eye level, and they can move it themselves.

  • The Moon and the planets · 4 out of 5

    Sharp on the Moon, and Saturn's rings are unmistakable at 130×. Jupiter shows two belts and four moons.

  • Learn my way around the sky · 4 out of 5

    Fast enough to point that star-hopping stays fun.

  • Nebulae, clusters and galaxies, by eye · 3 out of 5

    The brighter half of the Messier list, from a decent sky.

  • Taking it with me · 3 out of 5

    Fits in a car boot easily; hand luggage, no.
