  • Sky-Watcher Quattro 12S

    Price £929.00

    The QUATTRO series with their fast f/4 focal ratios, have been specially designed for high quality astrophotography with short exposure times. They are of course also fine telescopes for visual observations. 

    Please note the QUATTRO-12S is internally darkened and does not contain baffles like the other Quattro models.

  • The new Sky-Watcher EXPLORER-130PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-130P Black Diamond Series. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision.

  • The new Sky-Watcher EXPLORER-200PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-200P 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.
