Sky-Watcher 10" Dobsonian Collapsible Newtonian Telescope

The Sky-Watcher 10" Dobsonian Collapsible Newtonian Telescope represents a compelling blend of portability, affordability, and impressive light-gathering capability, making it a popular choice for both aspiring and seasoned stargazers. Featuring a massive 254mm (10") parabolic primary mirror, this telescope provides outstanding light collection for bright and detailed views of celestial wonders. Its 1200mm focal length delivers a moderate ƒ/4.7 ratio, expertly balancing a wide field of view with versatile magnification options that allow you to explore the cosmos with incredible depth.

One of the most amazing aspects of this instrument is its innovative collapsible truss-tube design, which allows the telescope to retract into two compact sections for effortless transport and storage. This unique feature overcomes the portability limitations common to traditional large Dobsonians, making it easy to take to dark-sky locations. Supported by a simple and user-friendly Dobsonian mount, this telescope excels at showcasing various celestial wonders; you can observe the intricate details of Jupiter's Great Red Spot and Saturn's rings, explore the dust lanes of distant galaxies, and resolve close binary star systems with stunning clarity.

Product Features in Detail

Massive Light-Gathering Power

The 10-inch aperture is widely considered the "sweet spot" for serious visual astronomy. It collects enough light to reveal the spiral arms of galaxies, individual stars in globular clusters, and the intricate "veins" within the Orion Nebula, providing an experience that smaller telescopes simply cannot match.

Patented Flex-Tube System

Unlike solid-tube Dobsonians that require a large vehicle for transport, the Flex-Tube design uses three sturdy sliding rails. This allows the optical tube to collapse to nearly half its length in seconds, significantly improving portability while maintaining perfect optical alignment (collimation).

Smooth Dobsonian Navigation

The telescope sits on a classic Alt-Azimuth rocker box made of heavy-duty materials. Using Teflon bearings for smooth rotation, it allows you to move the telescope intuitively by hand—just point and look—making it one of the easiest mounting systems to master.

Planetary and Lunar Detail

With a maximum practical magnification of over 500x, this telescope is a powerhouse for solar system observation. You can see the shadow transits of Jupiter’s moons, the Cassini Division in Saturn’s rings, and thousands of tiny craters on the lunar surface.

High-Contrast "Fast" Optics

The ƒ4.7$ parabolic mirror is designed to bring all light rays to a single point, eliminating spherical aberration. Combined with ultra-thin secondary mirror supports, this results in high-contrast views and minimal diffraction, even on the brightest celestial targets.

2-Inch Dual-Fit Focuser

The included Crayford-style focuser accepts both standard 1.25" eyepieces and professional 2" wide-field eyepieces. This versatility allows you to switch from "space-walk" views of the Milky Way to high-power, zoomed-in views of planetary disks with ease.
