Used SkyWatcher 10" Classic 250P Dobsonian

This is a 10" dob in good shape.  Although the body is clean, and in excellent shape, there are a couple of issues with it.  The primary mirror is a bit dusty.  Not enough to significantly affect your views, but there is dust on it. 

Additionally, the focuser is loose in that you can push down on it with your hand and it will slide down.  However, to paraphrase the old doctor joke, if you don't do that, it won't do that.  We've put heavy two-inch eyepieces in, and it holds them in place well.  We have read articles where this can be adjusted, but we have not yet adjusted it ourselves.  

• 10” (254 mm) Dobsonian-style Newtonian
• 1200 mm focal length (f/4.7)
• 2” single-speed Crayford-style focuser with 1.25” adaptor
• Super 25 & 10mm 1.25” eyepieces
• 9×50 finderscope
• Solid rocker-mount with Teflon bearings and tension clutch for altitude
• Teflon bearing for azimuth

This dob was already built by its previous owner, and we don't have the shipping boxes for it, so this is for in-store pickup only.  

Description

The Sky-Watcher Traditional 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.
