title: Sky-Watcher Classic 250 Dobsonian 10-inch Aperature Telescope – Solid-Tube – Simple, Traditional Design – Easy to Use, Perfect for Beginners (S11620)
text: Product Description High-Quality Light Buckets with Old School Charm Featuring large apertures and easy functionality, Sky-Watcher’s Traditional Dobsonian telescope makes the perfect beginner scope. Developed in the 1970s, the Dobsonian-style telescope is an inexpensive solution for bright, detailed visual observing using a simple design. The name ‘Dobsonian’ comes from the telescope’s inventor, John Dobson, a Vedantan monk and sidewalk astronomer who dedicated his life to astronomy outreach. Dobson was notorious for constructing large aperture reflecting telescopes capable of deep sky viewing, using low cost materials. These were often made with found materials, heavy cardboard tubes, recycled porthole glass and plywood mounts. Dobson encouraged other astronomers to assemble their own telescopes and taught workshops on telescope making. Sky-Watcher carries on the legacy Dobson left behind with our Traditional Dobsonian telescope. Often referred to as ‘light buckets’, Dobsonians provide users with the highest possible aperture for their money when compared to telescopes of a similar size, such as Schmidt-Cassegrains or refractors. Dobsonians use a simple, yet effective design, optimized for visual observation of faint objects, such as nebulae, star clusters and galaxies. At Sky-Watcher, we stay true to the traditional John Dobson design, using just two mirrors, a metal tube and a simple rocker box. Although we love computerized telescopes, using a star chart to find objects by hand can be far more fulfilling and will improve your knowledge of the night sky. Unplug your electronic devices, step outside and become immersed in the wonders of the universe. Not your Father’s Dobsonian Don’t let this simple design fool you! Dobsonian-style telescopes utilize their large aperture to give users bright, vivid detail. Both primary and secondary mirrors deliver 94% reflectivity, using borosilicate mirrors coated with quartz, titanium and silicon dioxide. With a finely-crafted parabolic primary mirror and coatings this bright, you’ll be viewing just as John Dobson intended. Sky-Watcher Innovation Unlike other models on the market, Sky-Watcher Dobsonians feature a patented Tension Control Handle which allow for easy tension adjustment, enabling the telescope to move freely around the sky. The Tension Control Handle also provides stability when using large eyepieces. Steel ball bearings provide smooth movement even when the handle is tightened. The simple rocker box mount with azimuth Teflon™ bearings is easy and straightforward enough for any beginner. The use of Teflon™ ensures smooth movement, yet creates enough friction to prevent any unintentional movement of the telescope. Accessories and Other Goodies While most telescopes limit the astronomer to 1.25” eyepieces, Sky-Watcher provides users with a beefy 2-inch Crayford-style focuser. Using the supplied 1.25 inch adapter you can take advantage of virtually any eyepiece on the market. Also included is a 9x50 finderscope and two eyepeieces (10mm & 25mm), perfect for the beginning astronomer!

title: Sky-Watcher Flextube 300 Dobsonian 12-inch Collapsible Large Aperture Telescope – Portable, Easy to Use, Perfect for Beginners, White/Black (S11740)
text: Product Description For years, Dobsonian telescopes have provided astronomers with the most bang for their buck using a large aperture and simple design. Viewing with a large aperture can provide a stellar experience, however the size of large reflector telescopes can pose problems for users looking to either store or transport their telescope from one location to another. The Sky-Watcher Collapsible Dobsonian solves this problem with a unique collapsible design using three retractable steel struts, allowing for easy storage and transit. Dobsonians are known for giving users a large aperture reflecting telescope at a low price, however they often lack portability. Sky-Watcher has innovated this classic telescope design by integrating a collapsible tube system, addressing users’ portability concerns. Sky-Watcher Collapsible Dobsonians feature a strut system carefully designed to ease setup time in the field while delivering consistent optical performance. Each strut has preset indentations which place the optics in the same position time after time, maintaining collimation. Unlike Dobsonians using a truss-tube system, Sky-Watcher’s Collapsible Dobsonian does not need to be disassembled. The strut system is comprised of three 1” steel poles, joining the bottom and top portion of the optical tube. When extended, three chrome locking screws hold the instrument in place. Unlike truss tube Dobsonians, Sky-Watcher’s Collapsible Dobsonian holds collimation extremely well, forgoing the need to collimate each time it’s used. The retracting design can shorten the optical tube up to 36%, making storage and transit much easier. At the heart of any Sky-Watcher telescope are observatory-grade optical components. The Collapsible Dobsonian is no exception, using components that yield exceptional contrast, 94% reflectivity and minimal vignetting. Mirrors are constructed with borosilicate glass, then coated with quartz, titanium and silicon dioxide to ensure an unparalleled viewing experience. Combining these superb optics with a large Dobsonian aperture helps ensure you’ll have bright, bold views of faint deep sky objects. To ensure Sky-Watcher Dobsonians remain easy to use, all Collapsible Dobsonians include a mount base that is so smooth, it can be rotated with the push of a finger. 8” and 10” models come complete with Teflon bearings, while the larger 12” models use steel needle bearings to ensure smooth and easy movement. At Sky-Watcher, we want you to feel confident in your purchase, knowing that your telescope will come with all required accessories to start using your telescope. All Sky-Watcher Dobsonian telescopes include a 2” Crayford focuser and a 1.25” adapter, allowing you to utilize both 2” and 1.25” eyepieces. Also included, are two 1.25” eyepieces (25mm and 10mm), a 8x50 finderscope and eyepiece tray.

title: SkyWatcher S11800 GoTo Collapsible Dobsonian 8-Inch (White)
text: Product Description Sky-Watcher’s GoTo Dobsonian epitomizes Sky-Watcher’s dedication to innovative ideas, combining our exclusive collapsible optical tube design with the convenience of a computerized GoTo mount. The SynScan hand controller allows users to point the telescope at specific objects, or tour the night sky with the touch of a button! Most astronomers crave the large aperture of a Dobsonian telescope, yet the lack of computerized GoTo features can be discouraging for some users. Sky-Watcher tackles this by adding motors to a traditional Dobsonian base, giving astronomers the benefits of a computerized GoTo system. Sky-Watcher’s signature SynScan hand controller uses two easy alignment methods, ‘Bright Star Alignment’ or ‘Two-Star Alignment’ for quick and easy setup. Once aligned, the SynScan hand controller can point to over 42,000 objects, including a full catalog of Messier, NGC and IC objects, providing you with a lifetime of celestial observing! While Dobsonian telescopes have a reputation for large apertures at a low cost, they often come at the expense of portability. The GoTo Dobsonian fixes this problem using our exclusive collapsible optical tube, featuring a strut system with three 1” steel poles and chrome locking screws. The strut system uses preset indentations which place the optics in the same position time after time, maintaining collimation. Unlike other Dobsonians using truss-tube systems, Sky-Watcher’s GoTo Dobsonian optical tube does not need to be disassembled before transporting from one location to another. With the ability to collapse up to 36%, these optical tubes can be easily transported in the backseat of most vehicles. At the heart of every Sky-Watcher telescope are professional-grade optics. The GoTo Dobsonian is no exception, using borosilicate mirrors coated in quartz, titanium and silicon dioxide. This yields an amazing 94% reflectivity, vivid contrast and minimal vignetting to deliver an exceptional viewing experience. Unlike other manufacturers, Sky-Watcher has a policy of providing you with all necessary accessories to get started. 8”, 10” and 12” GoTo Dobsonians include a 2” Crayford-style focuser, with a 1.25” adapter and two 1.25” eyepieces (10mm and 25mm). Whether this is your first telescope or not, there’s enough accessories for every kind of astronomer.
