The Verdict, and the Basis for It

The ESSLNB Telescope 700X70mm with K4/10/20 Eyepieces is the best Refractor Telescope for kids because it includes three different power eyepieces to help beginners learn how magnification works.

Choosing a first telescope often feels overwhelming because of the technical jargon surrounding aperture and focal length. A confusing purchase can lead to a blurry view of the moon that discourages a young astronomer from continuing their hobby.

The ESSLNB Telescope 700X70mm with K4/10/20 Eyepieces solves this by providing a versatile set of three eyepieces for immediate variety. You should choose the Celestron AstroMaster 90AZ Refractor Telescope if you prefer a more established brand name, or the 80mm Aperture 600mm Refractor Telescope if you want the lowest price point available.

Each Pick, Reviewed

The 3 picks below run from $109.99 to $188.88, reviewed in rank order.

ESSLNB Telescope 700X70mm with K4/10/20 Eyepieces

The ESSLNB Telescope 700X70mm with K4/10/20 Eyepieces made this list because it provides a pre-assembled starter kit that balances a low price point with the necessary 70mm aperture to resolve lunar craters and Jupiter’s moons.

What we like: This model includes three replaceable eyepieces (K4, K10, and K20) and a 3x Barlow lens to reach up to 525X magnification. It clears the 70mm aperture threshold required for clear lunar viewing while offering a smartphone adapter for capturing images.

Keep in mind: The 70mm aperture is at the minimum requirement for lunar detail, so this model is best for beginners who prioritize a complete accessory kit over high-magnification planetary imaging.

Celestron AstroMaster 90AZ Refractor Telescope

We selected the Celestron AstroMaster 90AZ Refractor Telescope because it offers a larger 90mm aperture and comes from a brand with a long history in consumer astronomy, providing a more stable viewing experience for kids.

What we like: The 90mm aperture exceeds the 70mm requirement for lunar craters, and the manual Altazimuth mount includes a panning handle for precision adjustments. It features a StarPointer red dot finderscope and a 4.4 rating from 4,612 ratings to support its reliability.

Keep in mind: This model is more expensive than the ESSLNB or EACON options, which may be a consideration for those on a strict starter budget.

80mm Aperture 600mm Refractor Telescope

The 80mm Aperture 600mm Refractor Telescope is a strong pick for kids because its 80mm aperture provides extra light-gathering capability over the 70mm minimum while remaining highly affordable.

What we like: This telescope features a 80mm large aperture and fully coated green optics glass to improve light transmittance. It includes a rough adjustment and positioning gimbal with a scale to help users point the telescope more easily.

Keep in mind: The provided specs do not list a wide-angle eyepiece, so you should check if the included K20mm and K9mm lenses provide a wide enough field of view for your specific needs.

What Separates One Refractor Telescope From the Next

Mount Stability for Small Hands

Mount stability for small hands depends on a sturdy base and intuitive controls. You should prioritize a tripod with a stable footprint over complex tracking systems. The ESSLNB Telescope 700X70mm uses an altazimuth stainless steel adjustable tripod, while the Celestron AstroMaster 90AZ features a manual Altazimuth mount with a panning handle for precision. For a child, a manual Altazimuth mount is often better than a computerized mount because it provides immediate tactile feedback and is easier to troubleshoot than complex motor programming. The EACON 80mm Aperture 600mm Refractor Telescope includes a positioning gimbal with a scale to help with movement.

Ease of Alignment

Ease of alignment is determined by the inclusion of a red dot finder rather than a complex finderscope. We selected these three models because they all include an erect-image red dot finder to help beginners center targets. The Celestron AstroMaster 90AZ specifically includes a StarPointer red dot finderscope. Because children may struggle with the fine adjustments of a high-magnification eyepiece, an erect-image diagonal—included with the Celestron—ensures the image is not upside down, making it easier to keep objects in view.

Weight for Portability

Weight for portability is a trade-off between the size of the optics and the ease of carrying the unit to a backyard. The Celestron AstroMaster 90AZ is built with a lightweight frame to balance its 90mm aperture. If you need a telescope that a child can move alone, look for a model with a pre-assembled design like the ESSLNB Telescope 700X70mm. For the EACON 80mm Aperture 600mm Refractor Telescope, check the specific weight of the tripod and gimbal in the listing to ensure it fits your transport needs.

Optical Clarity

Optical clarity depends on the aperture size and the coating of the glass. A 70mm or 80mm objective lens is the sweet spot for a beginner because these sizes clear the 70mm aperture threshold required to resolve lunar craters and Jupiter’s moons clearly without the heavy price of larger models. The EACON 80mm Aperture 600mm Refractor Telescope features a 80mm Large Aperture and fully coated green optics glass. The ESSLNB Telescope 700X70mm uses multi-fully coated optical glass, while the Celestron AstroMaster 90AZ features fully-coated glass optics to reduce reflections and improve light transmission.

Included Accessory Variety

Included accessory variety determines how many different views a child can see right out of the box. The ESSLNB Telescope 700X70mm includes three replaceable eyepieces (K4, K10, K20) and a 3x Barlow lens, providing a wide range of magnifications from 35X to 525X. The EACON 80mm Aperture 600mm Refractor Telescope comes with K20mm and K9mm eyepieces. The Celestron AstroMaster 90AZ includes a 20mm and 10mm eyepiece, an erect image star diagonal, and a smartphone adapter for capturing views.

You might also consider exploring various refractor telescope alternatives to achieve similar viewing results.

Who Buys Refractor Telescopes, and What It Really Costs

Who buys a Refractor Telescope, and what each one needs

  • Parents of elementary students — a telescope that avoids Magnification Over-rating to ensure the child sees clear images rather than blurry blobs
  • Homeschooling educators — a scope that meets the 70mm Aperture threshold to successfully resolve lunar craters for science lessons
  • Grandparents buying gifts — a durable entry-level refractor that avoids Mount Flexure to prevent frustration during first-time use
  • Middle school science teachers — a setup that demonstrates the difference between Achromatic and Apochromatic glass to explain light dispersion

What to budget for on top of the Refractor Telescope

  • Sturdy tripod — to prevent Mount Flexure when the telescope is balanced
  • Moon filter — to reduce glare when viewing high-contrast lunar features
  • Red light flashlight — to preserve night vision while navigating the telescope controls
  • Barstool or chair — to provide a stable viewing height for children

What you can leave out of the budget

Who Should Skip These Refractor Telescopes

These refractor telescopes do not include an Equatorial (EQ) mount. You cannot track celestial objects for long periods with these models because they lack the necessary tracking mechanism to compensate for the Earth’s rotation.

If you require the ability to track celestial objects for long periods, you need a telescope with an Equatorial (EQ) mount. None of the options on this page provide that specific tracking capability.

You should look for an equatorial mount refractor if you intend to do long-exposure astrophotography or track deep-space objects for extended periods. If you need a different configuration for your specific needs, you may want to see best refractor telescope for travel.
