The SkyWatcher Explorer 250PDS Parabolic 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.
Includes 9x50 finder, 2" 28mm Eyepiece, Dual speed focuser and tube rings!
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)
