This 80 mm aperture Sky-Watcher Esprit 80 ED APO Refractor was 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. This high-performance imaging telescope has a three-element air spaced objective lens design, and being apochromatic, false color is completely eliminated, yielding exceptional contrast and sharpness. The included 2-element field corrector lens guarantees a flat field across the entire imaging field.
The Sky-Watcher Esprit 80 ED APO Refractor incorporates their exclusive 2-speed Helinear Track focusing rack and pinion system with helical cut teeth on the rack gear, which provides a smooth, rock-solid focuser with zero image shift. In addition, all of the Sky-Watcher USA Esprit refractors come with these featured equipment components: an 8 x 50 right angle Finderscope, a 2-inch Star Diagonal, a 2-element field flattener, a camera adapter, a D-style Dovetail mounting plate, and a padded case. Optics are fully multi-coated for high contrast and bright images. The objective lens incorporates 2 BK-7 glass elements and one FPL-53 ED element.
