Product Details

Sky-Watcher Explorer-250PDS (EQ6 PRO) (f/4.7) 10" Parabolic Dual-Speed Newtonian Reflector Telescope - 10221/20854

The new Sky-Watcher EXPLORER-250PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-250P Black Diamond Series, but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also the tube length has been slightly shortened to optimise performance for prime-focus photography.

Even better performance for astro-photography and visual use can be achieved when used in combination with Sky-Watcher's Newtonian coma corrector (Prod.Code 20233)
