Esprit 150mm ED Triplet APO Refractor

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. 

In addition to superb optics, all Esprits feature an exclusive 3.4-inch dual-speed, Helinear track focusing system, which provides 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 a 8x50 right angle finderscope, 2-inch Star diagonal, M48 camera adapter, D-style dovetail, and padded case.
