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.

Designed with the discerning astrophotographer in mind, Sky-Watcher USA’s top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing thousands of dollars more.

With their three-element air spaced objective lens design, false color is completely eliminated, yielding exceptional contrast and sharpness. The included 2-element field corrector guarantees a flat field across the entire imaging plane. The Sky-Watcher exclusive Helinear Track focusing system provides a smooth, rock-solid focuser with zero image shift.

All Sky-Watcher USA Esprit refractors come with a 8 x 50 right angle finderscope, 2-inch Star diagonal, 2-element field flattener*, camera adapter, D-style dovetail and padded case. Everything you need to get out under the stars.
