The Sky-Watcher Esprit 100EDX Super APO Triplet Refractor is a high-performance imaging telescope engineered for astrophotographers who demand exceptional optical quality and mechanical precision. Featuring a three-element, air-spaced objective with FPL-53 extra-low dispersion glass, this refractor delivers virtually zero chromatic aberration, outstanding contrast, and pinpoint star performance.

Designed to rival refractors costing significantly more, the Esprit 100EDX offers a perfect balance of aperture, focal length, and portability, making it an ideal choice for serious deep-sky imaging.

The three-element, air-spaced lens system eliminates false color and produces sharp, high-contrast images across the field.

Premium glass ensures superior color correction and clarity, making it ideal for demanding astrophotography applications.

Fully multi-coated optics maximize light throughput, delivering bright images and deep, contrast-rich backgrounds.

• Heavy-duty rack-and-pinion linear rail design
• Zero image shift under load
• Dual-speed micro focusing for critical precision
• Perfect for large imaging trains and cameras

Easily frame your target with a rotatable focuser and built-in camera angle adjuster, allowing precise orientation without disturbing focus.

With a 100mm aperture and fast f/5.5 focal ratio, this telescope excels at wide-field and medium-scale deep-sky imaging.
