Designed with the discerning astrophotographer in mind, Sky-Watcher's top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing thousands of dollars more. With the Esprit's three-element, air spaced objective lens design, false color 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.

Description

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.

Quality Workhorse

The Esprit 80ED has been my workhorse for quality image acquisition. Sharp stars edge to edge with a fast f/5 focal ratio. I paired this with the APEX 0.65 to increase the focal ratio to f/3.25 for amazing nebula images (like this one https://flic.kr/p/2kL2Gj3). Focus is smooth and accurate and field of view allows for the capture of many larger nebula regions.

no regrets on the value of this unit.
