The Sky-Watcher Esprit 120 ED APO Refractor a purpose-built instrument for astrophotography, but is also great for visual astronomy. The triple air spaced optical design completely eliminates color aberrations, while the elite ED glass, fully treated with Sky-Watcher's propietary high-metallic coating, yields light transmission rates rivaling any scope on the market.
Still, the Sky-Watcher designers have gone two steps further to make sure the Esprit stands out among other elite astrographs. The scope comes with a 2-element field corrector, specially designed for this instrument, that guarantees a flat field across the entire imaging plane, much better than any third party field corrector ever could.
Also, the exclusive Helinear Track focusing system, which makes innovative use of bearings within a linear track system, keeps even heavier accessories nice and square inside the focuser, achieving smooth adjustment and zero image shift.
