Description
Sky-Watcher Skyliner 350P FlexTube Dobsonian Telescope
Discover the universe in stunning detail with the Sky-Watcher Skyliner 350P FlexTube Dobsonian—a powerful 14-inch telescope designed for serious amateur astronomers. With its large aperture, premium optics, and innovative collapsible design, this telescope delivers breathtaking views of deep-sky objects, planets, and the Moon, while remaining surprisingly portable for its size.
At the heart of the Skyliner 350P is a 355 mm (14″) parabolic Pyrex primary mirror that gathers an impressive amount of light, allowing you to observe faint nebulae, distant galaxies, and fine planetary features with incredible clarity. The fast f/4.5 focal ratio offers a wide field of view, making it ideal for scanning star clusters or enjoying immersive views of the Milky Way.
Unlike traditional Dobsonians, the FlexTube design allows the optical tube to retract and expand in seconds. This reduces its size for easier storage and transport—without the need to recollimate after setup. It’s a practical solution for astronomers who want big-aperture performance without the hassle of bulky equipment.
The telescope comes equipped with a dual-speed 2″ Crayford focuser for precise and smooth focusing, even at high magnifications. A 1.25″ adapter is included to accept a wide range of eyepieces and accessories. The solid Dobsonian mount features a smooth Teflon and bearing system for effortless motion, and tension control handles help you balance the scope easily, even when using heavier accessories.
Included in the package are two Super Plössl eyepieces (10 mm and 25 mm) and a 9×50 optical finderscope to help you locate celestial targets quickly and accurately.
Whether you’re observing Jupiter’s cloud bands, resolving the delicate arms of spiral galaxies, or exploring distant nebulae, the Sky-Watcher Skyliner 350P FlexTube Dobsonian delivers a powerful and immersive stargazing experience.
