The new Sky-Watcher EXPLORER-150PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-150P Black Diamond Series, but with two significant advantages.

The Sky-Watcher EVOSTAR series are two-element, air-spaced, multi-coated objective achromatic refractors. They are truly outstanding, high-performance, high-resolution instruments manufactured to extremely high standards of optical and mechanical precision

A compact but powerful, high-contrast, high-resolution Maksutov-Cassegrain telescope. High-transmission multi-coatings are employed on all optical surfaces for optimum performance.

All Skywatcher f/5 (‘fast’) Newtonian Reflectors and Dobsonian models feature high-quality parabolic primary mirrors to eliminate spherical aberrations inherent in ‘fast’ focal length reflector.

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

The new 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.

The new EVOSTAR DS-PRO Series ED Apochromatic refractors in their stunning Black-Diamond livery, house premium optics of the same quality and performance level as our now legendary Equinox series, making them superb instruments for both imaging and visual observations.
