Sky-Watcher Esprit 120 mm ED APO Triplet Refractor
What We Like About the Sky-Watcher Esprit 120 Refractor
- The 120mm air-spaced ED APO Triplet optics, made of FPL-53 ED and Schott BK-7 glass, coupled with multi-layers of a high transmission coating, yield sharp, high contrast views with no extraneous color.
- A thread-on doublet field flattener is included in the Sky-Watcher Esprit 120 Refractor package, providing a flat field from edge-to-edge.
- A good focuser is imperative when imaging, and the Esprit 120 comes with a 3.4" dual-speed rack-and-pinion Helinear track focuser
- The dew shield on the Skywatcher Esprit 120 retracts, making the length 7" shorter for storage and travel.
- A nice selection of accessories comes with this Esprit, including a 2" dielectric diagonal with 1.25" adapter, an 8 x 50 erect-image finder, a Canon M48 camera adapter, tube rings, and an aluminum case. Add a mount (the rings have a Losmandy- style dovetail bar) and a few eyepieces, and you're good to go.
More About Sky-Watcher Esprit 120 Telescope
Designed with the discerning astrophotographer in mind, Sky-Watcher USA’s top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing thousands of dollars more.
With their three-element air spaced objective lens design, made of high quality Schott BK-7 and FPL-53 ED glass, false color is completely eliminated, yielding exceptional contrast and sharpness. Knife-edge baffles in the optical tube increase contrast even further, and the included 2-element field corrector guarantees a flat field across the entire imaging plane. The Sky-Watcher exclusive Helinear Track focusing system provides a smooth, rock-solid focuser with zero image shift.
The Skywatcher Esprit 120 comes with a 9 x 50 right angle finderscope, a 2" star diagonal, a 2-element thread-on field flattener, and a camera adapter as well as a D-style dovetail and padded case. See highlights from the Sky-Watcher USA Esprit in the video below!
