This 120 mm aperture Sky-Watcher Esprit 120 ED APO Refractor telescope 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 120 ED APO Refractor telescope incorporates their exclusive 2-speed, 3.4" Helinear Track focusing rack and pinnion system with helical cut teeth on the rack gear, which provides a smooth, rock-solid focuser with zero image shift. The objective lens incorporates 2 BK-7 glass elements and one FPL-53 ED element. In addition, all of the Sky-Watcher USA Esprit refractors come with these featured equipment components: an 8 x 50 right angle RACI Finderscope, a 2-inch Star Diagonal, a 2-element field flattener, a Canon camera adapter, a D-style Dovetail mounting plate, and a padded rolling case. Optics are fully multi-coated for high contrast and bright images.
