Sky-Watcher Esprit 150EDX Triplet APO Refractor

The Sky-Watcher Esprit 150EDX is the flagship of the Esprit range, designed for advanced astrophotographers who demand flawless performance. Featuring a 150mm air-spaced apochromatic triplet lens crafted with Ohara FPL-53 ED glass, this refractor delivers exceptional colour correction and eliminates chromatic aberration, even on the brightest stars and planets. It provides diffraction-limited optics for crisp, high-contrast imaging across the entire visible spectrum.

Every internal component is engineered for contrast and clarity. Fully multi-coated lenses enhance light transmission, while a knife-edge baffling system minimizes stray light and internal reflections, thereby improving deep-sky detail. An optional 2-element field flattener is included to produce a flat, fully corrected 42mm image circle perfect for full-frame sensors.

Its premium 3″ linear dual-speed focuser is designed for heavy imaging payloads, offering smooth, precise adjustments with zero image shift. Built on dual tracks to prevent flexure, the focuser is also rotatable and indexed, allowing for perfect framing and balance during imaging sessions.
