Specifications
The Sky-Watcher Classic Dobsonian Telescope 254mm/1200mm (10") has 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 model include a 2" focuser with a 1.25" adapter, allowing the use of either eyepiece size. This model also include the new feature-tension control handle.

SW classic 250
A beautiful tool, simple and nicely made. This being my first 10"dob. I was surprised how big it is (assembled it takes up about a 21" x 55" corner of our home right now). The finder scope impressed me as well. Happy with my purchase!
