    Engineered for professional astronomy 

    The Sky-Watcher 80mm Esprit 80ED Triplet APO Refractor stands as a premier choice designed to cater to the exacting needs of enthusiastic astrophotographers. With three lens elements crafted from Ohara FPL-53 ED glass, this telescope effectively eradicates chromatic aberration, diminishes internal reflections, and significantly heightens contrast. As a result, it unveils the minutest intricacies of celestial objects in deep space, delivering remarkably crisp and detailed images.

    Furthermore, the Esprit 80 ED boasts a field-flattener that rectifies off-axis astigmatism and field curvature, expanding the field of view to a generous 42mm. Its distinctive Helinear Track dual-speed focuser has been meticulously engineered for photographic pursuits. Positioned on two tracks—one above and one below—it adeptly supports heavier cameras and offers complete rotation, allowing precise framing of a target on the sensor.
