Sky-Watcher Esprit 150ED Triplet Super APO - High-end f\/7 apochromatic refractor<\/h3>\n

Visit Sky-Watcher Esprit 150ED<\/strong> is the flagship of the Esprit range, designed for the most demanding astrophotographers and observers. With its 150 mm super-apochromatic triplet lens<\/strong> with air-spaced lenses (BK7 and FPL-53), it virtually eliminates colored fringing and delivers exceptional contrast, even on the brightest stars. Each element is treated with the high-transmission metal coatings (MHTC\u2122)<\/strong> for optimum light transmission.<\/p>\n

Sa 1050 mm focal length<\/strong> (f\/7) and its doublet field corrector<\/strong> included guarantee a perfectly flat field across the entire sensor, from full-frame to large modern CMOS. The focuser 3.4\u2033 double-speed rack<\/strong>This Helinear rail-mounted system enables smooth, precise, backlash-free focusing, and can be rotated for easy framing of your images.<\/p>\n
