9.5/10Our score

• 6 in Schmidt-Cassegrain optics
• Computerized GoTo mount
• 40,000+ object database
• SkyAlign

Six-inch optics and an automated mount make this a strong fit for observers who want help finding and tracking targets.

See it on Amazon

Pros

• GoTo system locates and tracks selected objects
• SkyAlign uses three bright stars or planets
• Compact Schmidt-Cassegrain design

Cons

• Computerized setup adds steps compared with a manual mount
• Computerized mount requires power

The NexStar 6SE combines 6 inch Schmidt-Cassegrain optics with a computerized alt-azimuth single fork arm mount. Select a target from its 40,000-plus object database with the NexStar+ hand control, and the mount slews to it and tracks it.

SkyAlign aligns the system by centering any three bright stars or planets, even when you do not know their names. This can suit you if you want help locating targets.

Celestron describes the 6SE as suitable for viewing lunar details, Jupiter's cloud bands, galaxies, and globular clusters. It includes a 25 mm eyepiece, star diagonal, StarPointer red dot finderscope, hand control, accessory tray, optical tube, mount, and tripod.

The computerized mount adds setup steps and requires power. Choose this scope if you want the mount to locate and track targets after alignment, and see our Celestron StarSense Explorer 150 mm review for a different way to find objects with a 150 mm tabletop Dobsonian.

7.9/10Our score

• 130 mm reflector aperture
• 650 mm focal length
• German equatorial mount
• Moon filter and phone adapter

A 130 mm reflector falls short of six inches but keeps the manual equatorial format at a smaller aperture.

See it on Amazon

Pros

• 130 mm aperture
• Fine-turn control cables help track objects
• Includes a Moon filter and phone adapter

Cons

• Not a 150 mm telescope
• Manual mount needs alignment

The SOLOMARK 130EQ has a 130 mm aperture, so it is a near-six-inch alternative rather than a 150 mm scope. Its 650 mm focal length and equatorial mount place it in the manual reflector category.

The scope includes two eyepieces, a 1.5x Barlow lens, a Moon filter, and a phone adapter. SOLOMARK describes its mount as having a dial and fine-turn control cables for positioning and tracking celestial objects.

Pick it if you want a smaller reflector with an equatorial mount and included accessories. If you require 150 mm aperture, choose one of the 150 mm models instead.

What changes between a 150 mm telescope and a smaller scope?

A 150 mm aperture gathers more light than a 90 mm refractor or 127 mm reflector. That can help with dimmer targets and finer details, while the mount, optical tube, and storage needs also matter.

A 150 mm telescope is about 5.9 inches across, so it is commonly described as a six-inch aperture model. The 127 mm PowerSeeker and 130 mm SOLOMARK are smaller alternatives, while the HSL and Skyoptikst have 150 mm aperture.

Aperture is one part of the view. Optical design, collimation, eyepiece choice, atmospheric steadiness, light pollution, and observing skill also affect what you can see.

For a first telescope, consider how much setup you are willing to do before each session. If compact size is a priority, compare these compact beginner telescopes.

Our guide to what telescope aperture is good for beginners explains how to weigh aperture against ease of use.

Should you choose a reflector or a Schmidt-Cassegrain?

A reflector uses mirrors to bring light to focus, while a Schmidt-Cassegrain folds the light path inside a compact tube. Both designs can provide six-inch aperture, but their tubes and mounts work differently.

The NexStar 6SE is the Schmidt-Cassegrain in this group, and its computerized mount is a central feature. The HSL and Skyoptikst are reflectors with equatorial mounts, as are the smaller Celestron and SOLOMARK models.

If you are new to mirrors, read what a reflecting telescope is before choosing a Newtonian. If you are deciding between six and eight inches, consider whether an 8 inch telescope is good for beginners.

Which mount makes sense for a six-inch telescope?

A computerized alt-azimuth mount can find and track selected objects after alignment, while a manual equatorial mount requires you to point and track the telescope yourself. Choose based on whether you want automation or prefer manual control.

The NexStar 6SE uses GoTo and SkyAlign for target selection and tracking. HSL, Skyoptikst, and the near-six-inch Celestron and SOLOMARK reflectors use equatorial mounts with manual controls.

The HETEKAN refractor has an alt-azimuth mount that moves horizontally and vertically. That can feel direct for casual viewing, but its 90 mm aperture does not meet the six-inch target.

How should you choose between these 150 mm telescopes?

Choose the mount and optical design first, then compare accessories and tube length. Adults weighing their options can also browse telescopes for adults.

A telescope you can set up regularly is more useful than extra aperture that stays in storage.

Pick the NexStar 6SE if you want computerized target finding and tracking. Choose the HSL 150EQ for a 150 mm reflector with a 750 mm focal length, or consider the Skyoptikst if its 1400 mm focal length suits your preferences.

The PowerSeeker 127EQ and SOLOMARK 130EQ are smaller manual reflector alternatives. The HETEKAN is a refractor with a smaller aperture and alt-azimuth mount.

Which 6 inch aperture telescope should you choose?

Choose the NexStar 6SE if you want computerized target finding and tracking, or the HSL 150EQ if you prefer a 150 mm reflector with manual equatorial controls. The Skyoptikst is another 150 mm option with a longer focal length.

If you are considering a larger aperture, compare our 10 inch telescope guide before deciding how much tube and mount you want to handle. For a manual reflector comparison, see the Celestron StarSense Explorer 150 mm review.

Frequently asked questions

Is a 150 mm telescope the same as a 6 inch telescope?

A 150 mm telescope is commonly described as a 6 inch telescope because 150 mm is close to 5.9 in. The aperture may be stated as 150 mm or rounded to 6 in.

Check the primary mirror or objective aperture, since focal length and tube length do not tell you how much light the telescope gathers.

What can you see with a 6 inch telescope?

A six-inch telescope can show lunar features, planets, and many deep-sky objects, though the view depends on sky conditions, target position, and telescope design.

The NexStar 6SE is designed to show lunar details, Jupiter's cloud bands, galaxies, and globular clusters. Darker skies can help with faint objects.

Is a 6 inch telescope good for beginners?

A six-inch telescope can work for a beginner who is ready to learn its mount and setup. A computerized model can locate and track selected targets, while a manual equatorial mount needs you to learn alignment and tracking.

For a simpler start, compare aperture choices in our beginner telescope aperture guide.

Should you choose a reflector or a Schmidt-Cassegrain?

Choose a reflector if you want a mirror-based optical design, or a Schmidt-Cassegrain if a compact tube and computerized GoTo system fit your priorities.

The guide to reflecting telescopes explains how mirrors form an image. Both designs can have six-inch aperture.

Is a 6 inch telescope a worthwhile upgrade from an 8 inch?

A six-inch telescope has less aperture than an eight-inch model, so it is usually a step down in light gathering rather than an upgrade. It may still appeal if a more compact setup or computerized mount matters more to you.
