The new Sky-Watcher EXPLORER-300PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-300P 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)
