SKY-WATCHER QUATTRO 300P IMAGING NEWTONIAN 12″

The new SKY-WATCHER QUATTRO 300P 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.
