  • 305 mm Newtonian reflector
  • 1200 mm (f/4)

  • 8×50 finderscope
  • Tube rings with D-style dovetail bar

The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2" dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography.

Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector.
