  • “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.”
