Field Flattener & Coma Corrector

 

“I’m pleased to report that the Esprit 120 really performed.”

“I compared its performance with high-end Officina Stellare and Astro-Physics 105mm and 130mm apos employing similar premium glass. Even at high magnification with a 3mm eyepiece, star images appeared just as sharp,aberration-free and colourless as the best.  I was Impressed.”

“it exhibited none of the aberration oddities I’ve seen in some test telescopes, effects created by cold temperatures pinching optics.”

“…the Esprit 120’s performance matches the best in the business at a competitive price…”

“Sky-Watcher’s Esprit refractors become very attractive options for anyone looking for the best.”

The Esprit ED APO 120mm Telescope from Sky-Watcher is a 3-element refractor telescope designed for astrophotographers. The optical system features apochromatic extra-low dispersion (ED) glass and fully multicoated optics. A 2-element threaded field-flattener corrects distortion that can occur at the edges of the field of view. This combination makes astrophotographic images clear and sharp, with high-contrast and true-color transmission, from one edge of the field of view to the other. With a focal ratio of f/7, this medium speed telescope is well-suited for astrophotography.

The 2" rack-and-pinion Helinear Track focusing system allows you to bring celestial objects into precise focus with virtually no shift. The focuser features tracks above and below the focus tube. This gives the mechanism two points of contact, keeping focuser level even with a camera mounted on it. The Esprit comes with a 90° star diagonal with dielectric coatings. These coatings provide better than 99% light reflection. The telescope also comes with a 8x50 right-angle erector finderscope, a Cannon 48mm T-Ring photo adapter, and a foam-lined aluminum case.
