    Sky-Watcher's Flextube Dobsonian

    Often referred to as a "light bucket", Sky-Watcher Flextube Dobsonians utilizes an innovative collapsible optical tube design, giving users the benefits of a large aperture in a portable design. Using just two mirrors, an aluminum tube and a rocker box, Sky-Watcher honors the simple telescope design invented by John Dobson with their line of Dobsonians. If you're new to astronomy and want to experience bright and vivid planetary viewing, this is the scope for you.

    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.

    Great scope
    5 Stars
    Great scope
    I highly recommend investing in this scope. It is well worth the price. If your new to astrology, like me, I recommend you purchase a laser collimator, barlow lens, lunar lens, and a small hex wrench for collimation. The scope comes with every thing you'll need to get started, but if you purchase these other items along with it you'll save some time. The scope itself is relatively heavy, as is the base, but they come apart very easy and can be easily manipulated. Also want to point out that the mirrors do shift when your moving and you will need to collimate before you get started viewing the vastness of our universe. Peace be with you and clear skies!
