The Sky-Watcher 10 Inch Flextube Dobsonian is a Newtonian reflector that combines exceptional light-gathering power with innovative portability through its patented collapsible truss-tube design. With a 250mm aperture and 1200mm focal length (f/4.7 ratio), it delivers 1235 times more light-gathering capability than the human eye while the parabolic borosilicate mirror with 94% reflectivity provides excellent contrast for detailed observation of nebulae, galaxies, and star clusters. The collapsible design retracts to just 31.5 inches for transport yet extends to 44 inches for observation while maintaining collimation, making this large-aperture telescope surprisingly portable for amateur astronomers seeking substantial viewing capability without a bulky installation.
