“I’m pleased to report that the Esprit 120 really performed.”

“I compared its performance with high-end Officina Stellare and Astro-Physics 105mm and 130mm apos employing similar premium glass. Even at high magnification with a 3mm eyepiece, star images appeared just as sharp,aberration-free and colourless as the best.  I was Impressed.”

“it exhibited none of the aberration oddities I’ve seen in some test telescopes, effects created by cold temperatures pinching optics.”

“…the Esprit 120’s performance matches the best in the business at a competitive price…”

“Sky-Watcher’s Esprit refractors become very attractive options for anyone looking for the best.”

- Three pages review on SkyNews by Alan Dyer

Review in SkyNews MAR/APR 2012 ( http://www.skynews.ca/  | review).


The Sky-Watcher Esprit line of high-quality ED Triplet APO refractors will perform flawlessly whether you enjoy it as a visual instrument or use it as a giant lens to image the Universe with one of today's amazing CCD cameras. The designers of this telescope line concentrated on the desires and requirements of the avid astro-imager, from a three-element apochromatic objective with included thread-on field flattener to the beefy oversized micro-focuser.

The air-spaced ED APO optics are fully multi-coated for extra clarity, contrast, and protection, and the two-element corrector, which comes standard with the Sky-Watcher Esprit, will ensure a flat field across the entire focal plane. This system produces a 40mm image circle, and you have about 69mm of back focus for plenty of imaging accessories. The dew shield, when extended, will protect the optics from dew and help increase contrast by blocking stray light that might otherwise strike the glass. However, the shield is fully retractable when necessary in order to shorten your OTA for storage and travel

The Helinear Track Focusing System, a Sky-Watcher exclusive, is a rock-solid 2.7" rack & pinion focuser that will perform smoothly, without image shift, due to the extra support rail on the top of the drawtube. The micro focuser allows you to make course and fine adjustments to focus, and the knobs are easy to turn, even with cold hands or with gloves on. A thread-on step down ring takes the opening down for 2" accessories, and a 2" to 1.25" adapter is included in the package.

Accessories are a big part of any telescope system, and Sky-Watcher wants to make sure that you start out right. Included with every Esprit refractor is a 2" dielectric diagonal, a 9 x 50 RA erect-image finderscope and bracket, a Canon camera adapter, tube rings with a CGE ("D" style) dovetail bar, and an aluminum foam-lined case.

Sky-Watcher Esprit 120ED APO Refracting Telescope

Esprit 120ED and 150ED Super APO refractors have a doublet field flattener to get a flat field and minimize aberration and distortion. Their M48 adapter for cameras assure larger clear aperture than M42 adapter to reduce halation as much as possible. Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image. 

Main Features:
- Premium optical materials
- Short focal length and full frame corrected focal plane
- Excellent field flatness
- Precision linear power focuser is standard
- Metallic high-transmission lens coatings
- Light-baffled optical systems
- Telescope tube attachment hardware
