Reflector Telescopes

Reflector telescopes use mirrors to gather light, giving you the most aperture for your money for faint galaxies, nebulae and star clusters. Shop compact 114mm Newtonian reflectors on equatorial or alt-az mounts and big-aperture Dobsonian telescopes from 6-inch tabletop models to 10-inch truss tubes.

Why Reflector Telescopes Excel at Deep-Sky Astronomy

Reflector telescopes are among the most popular astronomy telescopes thanks to their ability to gather large amounts of light and reveal faint celestial objects. Whether you're interested in observing galaxies, nebulae, star clusters, or planets, reflector telescopes offer exceptional performance and value. Explore the information below to learn more about Newtonian and Dobsonian designs, telescope aperture, and how reflector telescopes can enhance your stargazing experience.

Explore Scientific | Reflector Telescopes

Explore the depths of the universe with Explore Scientific’s diverse collection of reflector telescopes, designed to deliver powerful, high-contrast views of faint deep-sky objects like galaxies, nebulae, and star clusters. Reflecting telescopes (also known as Newtonian reflectors) use a system of mirrors rather than lenses to gather and focus light, making them an ideal choice for astronomers who want large apertures at a more accessible price point. Whether you're searching for your first serious astronomy telescope or looking to upgrade to a larger, more capable instrument, our reflector lineup includes a wide array of options. From compact Newtonian reflectors perfect for visual observation to large aperture Dobsonian telescopes designed for immersive views under dark skies, these instruments are optimized for performance, portability, and ease of use. Key models feature high-quality parabolic primary mirrors, low-expansion glass, and sturdy optical tube assemblies that minimize optical distortion and maximize image clarity. Our Dobsonian telescopes are particularly popular for their simple, intuitive mounting systems and unbeatable value when it comes to aperture size, a crucial factor for observing dim, distant celestial objects. Explore Scientific reflector telescopes are available in a range of apertures including 114mm, 130mm, 152mm, and 254mm, allowing users to choose the right balance between light-gathering power and portability. Advanced users will appreciate features like dual-speed Crayford focusers, collimation aids, and compatibility with a wide range of astrophotography accessories. These telescopes are also a great choice for astronomy education and public outreach, offering bright and detailed views of the Moon, planets, star fields, and beyond. When paired with quality eyepieces and filters, they become even more versatile tools for both visual observation and imaging.

Newtonian vs Dobsonian

Most reflectors here are Newtonian designs: a curved primary mirror at the bottom of the tube and a small flat mirror that sends the light to the eyepiece. A Dobsonian is a Newtonian on a simple rocker base that you point by hand, so nearly all the cost goes into the mirror. A Newtonian on an equatorial mount can track the sky with slow-motion controls or a motor.

Reflector Telescope FAQ

Is a reflector telescope good for beginners?

Yes. A 114mm reflector or a 6-inch tabletop Dobsonian is an affordable first telescope that shows lunar craters, Saturn's rings, Jupiter's moons and bright nebulae like M42 in Orion. See all beginner telescopes.

Do reflector telescopes need collimation?

Yes, occasionally. Collimation means lining up the mirrors, and it takes a few minutes with a collimation cap or laser collimator. Check it before a session, especially after the telescope has been moved.

What can I see with a 6-inch or 10-inch reflector?

A 6-inch reflector shows hundreds of star clusters, nebulae and the brighter galaxies, plus fine detail on the Moon and planets. A 10-inch gathers almost three times as much light, showing spiral structure in bright galaxies under dark skies and resolving globular clusters into individual stars.

What warranty do your reflectors have?

Explore Scientific telescopes carry a limited lifetime warranty for the original owner (electronics are covered for 2 years). Explore One and National Geographic telescopes carry a 1-year limited warranty. Register within 60 days of purchase to activate coverage.
