The Sky-Watcher Flextube 250P f/4.7 Dobsonian is a 10-inch collapsible Newtonian reflector designed for serious visual observing of deep-sky objects. With its patented truss-tube design, the telescope collapses to just 31.5 inches for easy transport while maintaining collimation, making it practical for amateur astronomers to explore faint nebulae, star clusters, and galaxies from dark-sky sites. The instrument features a parabolic primary mirror with 94% reflectivity coatings, smooth Teflon bearings, and a patented tension control handle for stable tracking, combined with a 2-inch Crayford focuser that accepts virtually any eyepiece.
