Sky-Watcher ESPRIT-70EDX F7 Super APO Triplet Refractor Telescope

Sky-Watcher ESPRIT-70EDX F/7 Super APO Triplet Refractor Telescope

Sky-Watcher ESPRIT – The Spirit of Perfection

The Sky-Watcher ESPRIT-70EDX is a compact, premium apochromatic refractor engineered for serious astrophotographers who demand outstanding optical precision in a portable format. Introduced as part of Sky-Watcher’s latest ESPRIT EDX generation, this 70mm Super APO triplet delivers exceptional sharpness, contrast, and colour fidelity — rivaling far larger and more expensive instruments.

Designed primarily for imaging but equally capable for visual observing, the ESPRIT-70EDX produces beautifully corrected, high-contrast views with virtually zero detectable chromatic aberration, even on bright stars and planets.

Premium Triplet Optics with Hoya FCD100 ED Glass

At the heart of the ESPRIT-70EDX is a finely matched three-element apochromatic objective, incorporating premium Japanese Hoya FCD100 ED glass. This advanced optical design ensures pinpoint stars, excellent colour correction, and superb micro-contrast across the field.

Each air-to-glass surface is treated with Sky-Watcher’s proprietary Metallic High-Transmission Coatings (MHTC), delivering exceptional light throughput approaching 99.5%. These advanced coatings maximise contrast while suppressing reflections and scatter — ideal for capturing faint nebulae and galaxies.

With its f/7 focal ratio and 490mm focal length, the ESPRIT-70EDX offers a versatile balance of wide-field capability and fine detail, and is fully compatible with full-frame sensors.

Precision CNC Linear Power Focuser

The telescope is equipped with a rock-solid CNC-machined dual-speed 11:1 rack & pinion linear power focuser, designed for modern imaging payloads. The 2.8" indexed drawtube provides:

• High accessory load capacity

• Zero image shift

• Smooth, precise fine focusing

While the main focuser is fixed, a 360° rotatable adaptor on the drawtube allows easy camera framing. A built-in carrying handle adds convenience during setup and transport.

An optional 0.92× focal reducer/flattener (Sky-Watcher code 20332) is available separately for wider fields and faster imaging.

Compact, Portable, and Built for Imaging

Despite its premium construction, the ESPRIT-70EDX remains highly portable. The aluminium optical tube features internal baffling for improved contrast, a retractable dew shield, CNC-machined tube rings with carrying handle, and a 45mm dovetail bar for secure mounting.

Everything packs neatly into the supplied foam-lined aluminium carry case, making this an ideal grab-and-go astrograph for travel or backyard observatories.
