The Sky-Watcher Esprit 120 is a world class 5" refractor. It's a stunning instrument for deep sky imaging.

With the Esprit's three-element, air spaced objective lens design, false colour is virtually eliminated, yielding exceptional contrast and sharpness. Each element is fully multi-coated with Sky-Watcher's proprietary Metallic High-Transmission Coatings (MHTC), producing a transmission rate that rivals any refractor on the market.

In addition to superb optics, all Esprits feature exclusive dual-speed, Helinear track focusers, which provide smooth, rock-solid focusing with zero image shift. Using a captain's wheel design all focusers can be rotated, giving astrophotographers flexibility when framing their image.

As is customary, Sky-Watcher supplies everything you need to get out under the stars, including a 2-element field corrector, which guarantees a flat field across the entire imaging plane. All Esprit refractors also come with an 8x50 right angle finderscope, 2-inch star diagonal, M48 camera adapter, mounting hardware, and padded case.
