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.
