Starlight Xpress SX-42 camera kit is a joint effort between Sky-Watcher USA and Starlight Xpress in honor of our 20th Anniversary. The SX-42 addresses all usual headaches when setting up a new system. The back-focus is matched for all Sky-Watcher correctors, simply thread the camera system onto the corrector and you are ready to go. All camera components are produced by Starlight Xpress in the UK and meet their highest of standards.

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.
