6-INCH DOBSONIAN
The Sky-Watcher Dobsonian Telescope 153mm/1200mm (6") have a "paraboloidal" primary mirror to
eliminate spherical aberration and a four-arm, secondary- mirror bracket with fine supports (0.5mm
thick), to reduce diffraction spikes and light loss. In addition, this models include a 2" focuser with a
1.25" adapter, allowing the use of either eyepiece size. This models also include the new
feature-tension control handle.
