SKYWATCHER PHOTOGRAPHIC NEWTONIAN 150 F/5
SKYWATCHER PHOTOGRAPHIC NEWTONIAN 150 F/5 is backordered and will ship as soon as it is back in stock.
The Sky-Watcher 150mm f/5 Newtonian is a compact telescope optimised for astrophotography. Its oversized secondary mirror provides a wide illuminated field, making it well-suited for cameras with large sensors.
The optional Sky-Watcher f/5 coma corrector effectively eliminates coma, delivering a wide, corrected field ideal for astrophotography.
The 2" Crayford focuser features a dual-speed (10:1) reduction for precise, backlash-free focusing—essential for both imaging and detailed visual work.
The collimatable secondary mirror is adjustable via three grub screws and a central spring-loaded screw for offset alignment. The primary mirror uses three pairs of push-pull screws for accurate collimation.
The aluminium optical tube is internally blackened to suppress stray light, reduce reflections, and improve contrast.
