Collapsible Dobsonian with 3-Points Tube Locking System Dobson Wooden Mount Tension Control System Diffraction Limited Parabolic Mirror Eyepiece 1.25' Super Plossl 25 mm (48x) Eyepiece 1.25' Super Plossl 10 mm (120x)
The Sky-Watcher Flex Tube Dobsonian has an improved design with a collapsible system which allows the telescope to be easily stored or transported. The 3 metal bars, used to fully extend the tube, have an auto-lock spring loaded system that simplifies the set up of the telescope so only one person is required to fully extend the tube.
The rigidity of the telescope keeps the mirrors collimated and the tension control system keeps the telescope balanced, so it is not necessary to move heavy counterweights. To top it off, the Sky-Watcher Collapsible Dobsonians are equipped with a 2″ Crayford focuser and focuser locking screw.
