The 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-Watchers Newtonian coma corrector (SKY-20233).
