  • Sky-Watcher Esprit EDX 70 Super APO Triplet

    The Sky-Watcher Esprit EDX 70 is engineered for the discerning astrophotographer, delivering professional-tier imaging performance in a highly portable format. Utilizing a sophisticated three-element, air-spaced objective lens design, this refractor completely eliminates false color to provide exceptional contrast and sharpness for wide-field deep-sky capture.

    By using laboratory-matched lens assemblies and high-end extra-low dispersion elements, the Esprit EDX 70 achieves unrivaled clarity. Whether you are a dedicated imager or a visual observer, this "Super APO" provides the elite performance typically found in instruments costing significantly more.

    Advanced Triplet Optics and FCD-100 Glass

    The core of the Esprit EDX 70 is its 70mm apochromatic triplet objective. Unlike standard doublets, this three-element design offers superior correction for spherical and chromatic aberrations. Specifically, the 70mm model utilizes premium FCD-100 glass for its ED element, ensuring that light across the visible spectrum is brought to a precise, common focus.

    The optical system features knife-edge baffles throughout the tube to maximize contrast by suppressing stray light reflections, ensuring a jet-black background for your astronomical data.

    Exclusive Linear-Track Focusing System

    To meet the demands of modern imaging trains, the Esprit EDX 70 is equipped with Sky-Watcher's exclusive 2.7-inch linear-track rack-and-pinion focuser. This design is engineered to be rock-solid, providing a stable platform that eliminates image shift during critical focusing.

    • Precision Control: The focuser includes a micro-focus knob for ultra-fine adjustments, essential for achieving pinpoint stars with fast f/7 optics.
    • Generous Image Circle: When paired with the optional two-element field corrector, the system delivers a 44mm image circle, providing edge-to-edge illumination and flatness for full-frame sensors.
    • Internal Baffling: Precision-placed internal baffles further enhance the optical performance by reducing internal scatter.

    Ultra-Portable Professional Astrograph

    Weighing only 7 pounds and featuring a compact length of 14.5 inches when retracted, the Esprit EDX 70 is the ultimate high-end travel telescope. Its 490mm focal length hits the "sweet spot" for expansive deep-sky targets, allowing for breathtaking wide-field compositions of large nebulae and star fields.

  • Does the Esprit EDX 70 require a field flattener?

    For large-sensor astrophotography (APS-C or Full-Frame), an optional two-element field corrector is available to guarantee a flat field across the entire 44mm imaging plane. This ensures pinpoint stars even in the extreme corners of your images.

    What type of glass is used in the 70mm model?

    The Esprit EDX 70 specifically uses FCD-100 glass for its extra-low dispersion (ED) element. This is a premium fluoride-based glass that provides exceptional color correction and clarity.

    What kind of mount does it use?

    The EDX 70 comes with high-quality mounting rings and a V-style (Vixen-style) dovetail plate, making it compatible with a wide variety of portable equatorial and alt-azimuth mounts.

    Is the focuser strong enough for heavy cameras?

    Yes, the 2.7-inch linear-track design is specifically engineered for a rock-solid, zero-image-shift performance even under the load of heavy imaging accessories.
