Celestron NexStar 6 SLT Schmidt Cassegrain Telescope

Built around Celestron’s proven 6-inch (150mm) SCT optics and paired with the beginner-friendly NexStar SLT computerized GoTo mount, this telescope is ideal for Moon, planets, bright nebulae, globular clusters, and galaxies—all while being easy to carry, quick to set up, and simple to operate.

Why the NexStar 6 SLT is a Best-Selling 6” GoTo Telescope

1) Powerful 6-inch Celestron SCT optics (High contrast + long focal length)

The Schmidt-Cassegrain design delivers a long focal length in a compact tube, giving you:

• High magnification performance for Moon and planets (Jupiter bands, Saturn rings, lunar craters)

• Excellent contrast for double stars and globular clusters

• Great all-round capability with a wide range of eyepieces and accessories

With a 150mm aperture, the NexStar 6 SLT collects plenty of light for bright deep sky targets too—Orion Nebula (M42), Ring Nebula (M57), Hercules Cluster (M13), Andromeda Galaxy (M31) (under dark skies), and more.

2) Computerized GoTo mount with NexStar hand controller

The NexStar SLT GoTo mount helps you find objects quickly—especially useful under light-polluted city skies.

• Access a large database of celestial objects

• Track objects automatically once aligned

• Great for beginners learning the night sky without frustration

3) Fast setup and portable design

One of the biggest advantages of the 6” SCT is portability:

• Compact optical tube for easy travel

• Quick assembly tripod + mount + OTA

• A strong “grab-and-go” GoTo option compared to heavier 8” systems

4) Beginner-friendly alignment options

The NexStar system is designed so new users can start observing quickly. Once aligned, the mount points and tracks targets smoothly for visual observation. 78")
