Flextube 250P Collapsible Dobsonian

With a 10-inch aperture, the Flextube 250P collects 1235 times more light than the human eye, making it ideal for visual observation of faint objects such as nebulae, star clusters, and galaxies. The Flextube's patented truss design allows it to retract to just 31.5" for easier transport and storage, and then extends to 44" for observation. The optical tube uses a parabolic primary mirror constructed of borosilicate and coated with proprietary Radiant Aluminum Quartz (RAQ), producing a remarkable 94% reflectivity. Total weight is only 60.5 pounds, making it practical for one individual to explore the heavens with this truly big scope.
