Skywatcher Esprit 100ED - 100 mm F/5.5 FPL53 ED Triplet Apochromat
Sky-Watcher Professional ESPRIT apochromatic 3-element ED refractors are instruments of the highest quality with optical performance rivalling or exceeding similar telescopes of even the most famous high-end telescope brands.

The ESPRIT apo triplets are designed for the most demanding astrophotographers, for use with the optional M48 field flattener, but are also fine telescopes for visual observations. The premium, superbly-corrected optical systems deliver high-contrast images full of detail and zero detectable colour fringing, even on the brightest of objects.

The Skywatcher Professional ESPRIT 3-element ED APO refractor is one of the fastest apochromats in this aperture range. The focal ratio of f/5 makes the telescope interesting for astrophotographers. The optional flattener corrects the field of view and is even suitable for full-frame size sensors.

"Ein großartiger APO, der durchaus auch mit höher bepreisten Produkten mithalten kann. Die Verarbeitung und das gesamte Erscheinungsbild sind hochwertig. Die Abbildungsleistung ist erwartungsgemäß sehr gut. Für Weitfeld-Astrofotografie mit APS-C Sensor perfekt!"
