Sky-Watcher Flextube 300P 305mm (12") Collapsible Dobsonian Telescope

Sky-Watcher Flextube 300P 305mm (12") Collapsible Dobsonian Telescope

Due to high demand and global product shortages due to the pandemic, please call for availability.

The Sky-Watcher 12" Dobsonian telescope is an outstanding value for the level of light gathering and functionality that it provides. Deep space views are simply stunning.

It collapses by running up and down on three vertical bars fixed to the top section, which reduces the need for collimation upon setup, which can be an issue for truss-tube Dobsonians.

As an added bonus, if the instrument is collapsed slightly, binocular viewers will come to focus and can be used without the need for a Barlow or image amplifier - a big plus for deep space binocular viewing.
