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)
Quiet in operation, the EQ6i PRO mount has a maximum payload capacity of 25kg and is fully controllable with a smart device via it's Synscan Wi-Fi adaptor using the free Synscan Pro App for iOS, Android or PC.

PARABOLIC PRIMARY MIRRORSFeatures High Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal lengh reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, constrasty images, which are full of detail.
