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. Transport Anywhere, Anytime 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. Borosilicate? Gesundheit! 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”, 14” and 16” models use steel needle bearings to ensure smooth and easy movement. Upgraded Pro Models Sky-Watcher’s 14” and 16” Collapsible Dobsonian Pro models offer a few additional upgrades. Pro models also use a conical parabolic mirror to help reduce the weight of the primary and for faster cool-down time. Additionally, a 10:1 dual-speed Crayford-style focuser offers users a more precise method for focusing and needle bearings produce smoother, quieter movement. Pro models also include Sky-Watcher’s premiere collapsible mount which uses an easy-breakdown base for enhanced portability. Normally, these larger aperture scopes would be extremely difficult to transport but with Sky-Watcher’s innovative design these telescopes can be used anywhere.
