Sky-Watcher Esprit 120EDX Triplet APO Refractor

The Sky-Watcher Esprit 120EDX is a precision-engineered triplet refractor, designed for serious astrophotographers seeking superior optical performance and robust mechanical design. Featuring a 120mm air-spaced apochromatic triplet objective with premium Ohara FPL-53 extra-low dispersion glass, this refractor delivers outstanding colour correction across the visible spectrum, eliminating chromatic aberration even on the brightest targets.

With fully multi-coated optics and an internal knife-edge baffling system, the Esprit 120EDX offers enhanced contrast and brightness, bringing out fine structures in deep-sky objects. An optional 2-element field flattener is included to produce a flat 42mm image circle, ideal for full-frame camera sensors and critical astrophotography.

A heavy-duty 3" dual-speed linear focuser with 11:1 fine adjustment ensures smooth, precise focus with zero image shift even under heavy imaging loads. The focuser is rotatable and indexed, allowing for optimal framing and balance during imaging sessions.
