Sky-Watcher Esprit 120ED APO Triplet - Super APO f\/7 full-frame corrected refractor<\/h3>\n

Visit Sky-Watcher Esprit 120ED<\/strong> is a refractor apochromatic triplet<\/strong> high-performance lens designed for astrophotography and high-magnification observation. Supplied with a field corrector doublet<\/strong>it delivers a perfectly flat field<\/strong> and minimizes aberrations and distortions on full-format sensors. Sound linear focuser 3\u2033<\/strong> ensures precise, stable focusing, while the knife-edge diaphragm system<\/strong> and multilayer treatments<\/strong> guarantee high contrast, with no perceptible halo or colored fringing.<\/p>\n

Highlights<\/h3>\n
    \n
  • APO premium triplet optics<\/strong> chromatic reference correction, no visible color fringe<\/em> even on very shiny objects.<\/li>\n
  • Doublet field corrector<\/strong> Full-format image flatness, sharp stars from edge to edge. Attention not included.\u00a0<\/strong><\/li>\n
  • 48 mm opening<\/strong> wide illumination for high-resolution sensors, extremely low halos.<\/li>\n
  • Short focal length & f\/7<\/strong> ideal for nebulae, clusters and medium-sized galaxies.<\/li>\n
