The Sky-Watcher EXPLORER-150PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-150P 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.
ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.
150mm Parabolic Mirror for super quality images.
