About the Sky-Watcher Flextube 200P 8" Collapsible Dobsonian Telescope
If you love the superior light gathering capability of a Dobsonian telescope, but you want to be able to transport it easily then this offering from Sky-Watcher is tailored for you.
Many truss tube Dobsonians solve the portability problem by being designed to disassemble, which often results in a frustrating (and time-consuming) reassembly experience. Sky-Watcher have instead created a collapsible design. Just loosen three locking screws and bring the front and back cells together. Then lock them back down for transport. Preset indentations on the truss tubes allow you to easily extend the telescope again without losing collimation.
Teflon bearings allow movement so smooth that sweeping adjustments can be made with one finger. A tension clutch keeps the OTA firmly in position with the twist of a lever.
The 8" aperture and fast focal length of this telescope make it ideal for wide-field, deep-space observation of even the faintest nebulae and galaxies. Sky-Watcher's dedication to quality design and top-notch components result in an instrument that will delight even seasoned astronomers. The parabolic primary mirror and elliptical diagonal mirror are made of borosilicate glass which are finely polished to ensure high smooth surfaces and high-contrast images. On each mirror surface, aluminum is vacuum deposited and then over-coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied, resulting in 94% reflectivity and bold-bright images in the eyepiece.
