Which telescope should you choose to get started in astronomy?
The right first telescope isn't the most powerful one on paper: it's the one you'll actually take out of its box on a weeknight, without a fight.

Aperture matters more than magnification
The classic trap of telescopes sold in big-box stores is a bold magnification number splashed across the packaging — "675x," for example — on a box that in reality contains only a poor-quality optical tube. In amateur astronomy, the characteristic that truly determines what an instrument can show isn't magnification, but the aperture diameter (the main mirror or lens), expressed in millimeters.
A larger aperture gathers more light, which makes it possible to see fainter objects — nebulae, galaxies, star clusters — with more detail and contrast. Magnification, meanwhile, is simply adjusted by changing the eyepiece, and beyond a certain threshold (roughly twice the diameter in millimeters), the image becomes dark and blurry no matter how good the instrument is. A 130 mm aperture telescope with modest magnification will always show more detail than a 60 mm model boasting an outlandish magnification figure.
Refractor or reflector?
Two families of instruments dominate the consumer market. The refractor uses glass lenses at the front of the tube, like a spyglass: it's rugged, needs virtually no adjustment (collimation), and produces sharp, high-contrast images, especially of the Moon and planets. Its main drawback is cost: for the same aperture, a good refractor is markedly more expensive than a reflector, which limits affordable models to fairly modest diameters (around 70 to 90 mm).
The reflector (notably the Newtonian telescope) uses a concave mirror at the bottom of the tube. At the same price, it offers a much more generous aperture — often 130 to 200 mm on a beginner budget — making it particularly well suited to deep-sky observation. In exchange, its mirror requires an occasional adjustment called collimation, a simple operation once understood, but one that can be discouraging if it's never clearly explained.
For a first purchase, a Dobsonian-style reflector — a Newtonian mounted on a simple base, with no tripod or motorized drive system — is often the best simplicity-to-performance ratio: the tube points wherever you push it, with no complicated adjustment, for an unbeatable aperture at the price.
The mount matters as much as the tube
An unstable mount ruins the observing experience, even with excellent optics: the slightest vibration turns the image of a planet into an unusable shudder. Two main families exist. The altazimuth mount (including the Dobsonian's rocker box) simply moves up-down and left-right, like a camera on a photo tripod: intuitive, and more than sufficient for a beginner. The equatorial mount, aligned with Earth's rotation axis, lets you track a celestial object by turning a single axis — a real plus for long-exposure photography, but an unnecessary level of complexity for simple visual observation.
Another often overlooked point: weight and bulk. The best telescope is the one you actually take outside in the evening. A bulky tube left at the back of a closet because it's too heavy to carry out to the garden will never be as useful as a more modest but practical instrument.
The accessories that change everything
A telescope that ships with two or three eyepieces is enough to get started, but two additional accessories truly transform the experience. A red dot finder, which projects a simple point of light superimposed on the real sky, makes pointing infinitely more intuitive than a small inverted optical finder scope. And a low-magnification wide-field eyepiece makes it much easier to initially locate an object before zooming in with a more powerful eyepiece.
On a tight budget, it's better to prioritize a more generous aperture and good basic accessories rather than a pricier tube supplied with low-end eyepieces you'll have to replace anyway.
Examples of gear suited to beginners
The models below illustrate the categories described above — an entry-level Dobsonian, a more compact alternative, and an essential accessory. Always check reviews and availability at the time of purchase.
A travel telescope for viewing the Moon and planets, with a more generous aperture than a typical 70 mm.
- 80 mm aperture, more generous than a typical 70 mm for the same kind of use
- Amazon's Choice badge and a solid review count (594, 4.4 stars)
- Less established brand in astronomy gear than Celestron or Skywatcher
A lightweight travel telescope for viewing the Moon and bright planets on the go.
- No collimation needed, sharp image right away
- Light and compact, easy to take travelling
- More limited aperture than a Dobsonian at the same budget
Mounts on the telescope and projects a lit dot onto the real sky, to aim at an object before looking through the eyepiece.
- Makes pointing far easier than an inverted optical finder
- Very affordable, fits most telescope tubes
- Needs a reasonably dark sky to see the dot clearly
For viewing lunar craters, Saturn's rings and Jupiter's cloud bands, with no fiddly adjustments.
- Generous aperture for the price, ideal for deep-sky objects
- Ready to use immediately, no fiddly adjustments (Dobsonian)
- Simple alt-azimuth mount: no motorized tracking
Frequently asked questions
Do you need a telescope to see Saturn's rings?
Yes — good binoculars show Saturn as a slightly oval point, but you need a magnification of at least 30-40x, and therefore a real telescope, to clearly make out the rings as a disk separate from the planet. Our dedicated Saturn guide details the gear you'll need.
What budget should you plan for a first serious telescope?
Budget roughly 200 to 300 € for an instrument capable of showing Saturn's rings, Jupiter's bands and moons, lunar craters in detail, and the main deep-sky objects under good conditions.
Is a telescope for kids worth it?
"Toy" telescopes with very small apertures almost always disappoint, even the youngest users. A real 76 or 130 mm Dobsonian, simpler to use than you might think, offers a far better experience and can be handled from around age 8-10 with a bit of guidance.
