Sporting the large light bucket users have come to expect from a Dob, the Sky-Watcher Flextube 300P SynScan 12" f/4.9 Dobsonian GoTo AZ Telescope gives users great performance at a reasonable price. Its large parabolic Borosilicate primary mirror is treated with an aluminum coating that brings its reflectivity to over 94%, with a secondary mirror obstruction of just 5% by area. Unlike traditional Dobsonians that tend to be bulky and unwieldy, the Flextube's patented truss design allows it to retract to just 36" for easier transport and storage and extends to 55" with an impressive 1500mm focal length for observation.
