Designed with the discerning astronomer in mind, Sky-Watcher top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing much more. With their three-element air spaced objective lens design, false color is completely eliminated, yielding exceptional contrast and sharpness.
The 3" CNC machined 1:11 rotatable dual speed linear power focuser provides a smooth, rock-solid focusing with zero image shifts. The Esprit ED 120mm refractor comes with a 9 x 50 right angle finder scope, 2-inch Star diagonal, D-style dovetail, retractable dew cap and padded case.
The 2-element thread-on 48mm field flattener guarantees excellent field flatness across the entire 44 mm imaging plane. Its oversized lenses ensure a larger and clearer aperture and also extremely minimized halation.
