    Esprit 80 OTA Features

    World-Class Optics

    Chromatic aberrations and field curvature are things of the past with the Sky-Watcher Esprit series of super APO triplet refractors.

    Whether you’re photographing with a CCD or a full-frame DSLR, Esprits produce crystal clear images that rival the performance of other refractors costing thousands of dollars more. The Esprit series features extra-large image circles, providing astrophotographers with vignette-free images on large full-frame sensors.

    As you explore beyond the tube’s white glossy finish, it becomes apparent that the Esprit’s optical components are designed to court glass snobs near and far. The Esprit series is built around a fast focal length, air-spaced triplet objective, and a proprietary combination of matched lenses, designed to deliver optimum visual and photographic performance. Sky-Watcher’s signature Metallic High-Transmission Coatings (MHTC) – utilizing magnesium fluoride and zirconium oxide – is able to produce a transmission rate that challenges any other refractor on the market. All objective lenses are air-spaced, cooling to an ambient temperature faster than optical tubes using oil-spaced optics. Our optical tubes are fully baffled to eliminate any stray light.

    Solid and Precise Focusing

    It features paraboloidal primary mirrors made of Low-Expansion Borosilicate Glass resulting in substantially shorter cooling-down times.

    Whether you’re using the Esprit for imaging or visual use, Sky-Watcher’s proprietary 2.7” and 3.4” dual-speed focuser provides precise 10:1 rack-and-pinion focusing with zero image shift. The focusers are rotatable, allowing astrophotographers to easily frame their image. The large aperture focuser includes millimeter markings to assist with quick and accurate focusing.
