Which telescope for a child?

The short answer

• Under 7: no telescope. Light 8×30 or 8×40 binoculars, the Moon with the naked eye, a trip to see the Milky Way. Appetite first, instrument second.
• 7 to 10: a 130 mm tabletop Newtonian (130/650), that you will set up and point with them. It is the telescope they will still be using at fifteen.
• 10 to 14: 10×50 binoculars they can take out alone, or the same tabletop Newtonian if there is a motivated adult at home. Both, if the budget allows — they do not do the same thing.
• 14 and up: the adult answer. A 150/1200 Dobsonian if there is room, and the general guide applies.

The advisor — answer 'for a child' at the first question

What the child will see on the first night

This is the point that decides everything. A child does not compare the image with what an adult knows about Saturn; they compare it with the picture on the box. If the box shows a nebula in colour and the eyepiece shows a grey smudge, the telescope has lost, whatever it cost. Show them the Moon first — at a quarter, not full — because it is the one thing in the sky that looks like the photographs.

Second night, if Saturn or Jupiter is up: the ring clearly detached, the four moons in a line. Small, sharp, and real — a child understands very well the difference between a photograph and an object they are looking at. Keep the nebulae for later, and for a dark sky.

By age — and mostly by adult

The ages below are the ones people type into a search box, not thresholds. What actually changes from one band to the next is who sets the instrument up and who points it. Read yours, then the next one: the right present is often next year's.

At 4 or 5

No telescope. A child this age will not point anything alone and will not hold an eye on an eyepiece for more than a few seconds; that is not a criticism, it is motor skills. Light 8×30 binoculars, held in two hands, show the Moon with its seas and the Pleiades. The real outing is a dark sky on holiday and the Milky Way with the naked eye.

If a telescope arrives anyway — a grandparent, a box — put it on a quarter Moon and nothing else. It is the one target that looks like the picture on the carton.

At 6 or 7

The hinge. At six, still binoculars. At seven a first telescope becomes possible on one condition: you set it up, you point it, you decide when to go in. The child looks. The 76 mm tabletop Newtonian (76/300) is the smallest real telescope; it shows the Moon and Saturn's ring honestly and fits in a bag.

At 8 or 9

The age of the best present in this guide. A 130 mm tabletop Newtonian (130/650) sits on a garden table, is pointed by hand, needs no adjustment, fits in a cupboard. You will carry it out; they will look — and around nine they will start pointing it at the Moon themselves. It is the telescope they will still be using at fifteen.

At 10, 11 or 12

The question becomes independence. 10×50 binoculars with a second-hand photo tripod, a planisphere, and the child does their own evenings. The 130 mm tabletop remains the right telescope if there is a motivated adult at home; a telescope they cannot set up alone will stay in its box as soon as you no longer have the time. Both, if the budget allows — they do not do the same thing.

At 13 and up: for a teenager

A beginner like any other, with shorter arms and less patience for a complicated mount. The 150/1200 Dobsonian is heavy for a teenager but not too heavy, and it is the instrument that shows the most per euro; the 130 mm tabletop remains the answer if space is short. No equatorial mount, no GoTo: the general guide applies from here.

By budget

• Up to €100: 8×40 or 10×50 binoculars. The 76 mm tabletop Newtonian slips just under the line at today's price; below it there is no good telescope.
• €100–200: better binoculars with a tripod, or the 76 mm tabletop Newtonian (76/300) plus a decent eyepiece. No new 130 mm at this price; a used one, yes.
• €200–300: the 130 mm tabletop Newtonian. The best present on this list, by a distance.
• €300–400: the 150/1200 Dobsonian, if the child is over twelve and the house has the room. Otherwise the 130 mm and a good 8–10 mm eyepiece with the difference.

What not to buy

The first three outings

• Outing 1 — the first-quarter Moon, ten minutes, that is all. Have them look for crater shadows along the day-night line. Go in before they get cold.
• Outing 2 — a planet if there is one (Saturn in autumn 2026, Jupiter and Mars in February 2027), otherwise the Pleiades at low power. Let them point it themselves, even if it takes five minutes.
• Outing 3 — a dark sky, out of town, without the telescope: the Milky Way with the naked eye, binoculars for Andromeda. It is the outing they will remember.

Buy no accessory before the fifth outing. No Barlow, no filter, no extra eyepiece. By the fifth, you will both know what is missing, and it will probably be a chair.
