Triplet\u003c\/h2\u003e\n\u003cp\u003eThe Sky-Watcher Esprit EDX 100 Super APO Triplet combines a 100mm air-spaced ED triplet objective with a fast f\/5.5 focal ratio to deliver a flat, high-contrast imaging field free of chromatic aberration. Its 550mm focal length is ideal for wide-field nebulae, while the diffraction-limited optical quality resolves fine detail. The robust 16-pound optical tube is equipped with a 3.4\" dual-speed focuser, providing a stable and precise platform for serious astrophotography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e100mm f\/5.5 Super-Apochromatic Triplet Optics\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the Esprit EDX 100 is a three-element, air-spaced objective lens that virtually eliminates false color. This Super-Apochromatic design produces textbook-perfect star points and outstanding contrast, meeting a diffraction-limited (1\/4 wave) standard for professional-grade imaging. With fully multi-coated elements, light transmission is maximized for brighter images of faint deep-sky objects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e3.4-inch, 11:1 Dual-Speed Focuser\u003c\/h3\u003e\n\u003cp\u003eThe oversized 3.4-inch rack-and-pinion focuser uses a linear rail track to support heavy imaging trains without sag or image shift. An 11:1 dual-speed mechanism allows for exceptionally fine focus adjustments, critical for achieving sharp stars at the f\/5.5 focal ratio.

An indexed scale on the drawtube gives an accurate indication of the focus position for various accessories. The entire focuser assembly is rotatable, enabling you to frame your target perfectly without rotating the entire optical tube, and the internal knife-edge baffles maximize contrast by suppressing stray light.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eOver 225mm of Visual Back Focus \u0026amp; Dedicated Correctors\u003c\/h3\u003e\n\u003cp\u003eThe Esprit 120 EDX provides more than 225mm of visual back focus, measured from the end of the focuser tube with the 2\" adapter installed.

When paired with the optional ESPRIT 150 field flattener, designed specifically for this telescope, it gives excellent field flatness and full illumination with extremely minimized color fringing across the entire 44mm imaging plane. The flattener is not compatible with other telescopes, even refractors with the same aperture and focal length.\u003c\/p\u003e\n\u003cp\u003eThe optional imaging train is precisely defined: the flattener requires 100mm of back focus from its last lens element to the sensor.

A 1:11 dual-speed mechanism allows coarse adjustment and fine-tuning for critical focus. The whole focuser body can be rotated when the knobs are not in a convenient position, the diagonal ring rotates independently, an indexed scale on the drawtube shows the focus position for each accessory, and a locking lever below the focuser secures heavy loads.\u003c\/p\u003e\n\u003cp\u003eFor visual observers, the system offers more than 170mm of back focus from the end of the focuser tube with the 2\" adapter installed.
