Optimized for astrophotography, this focal reducer is specially designed for the telescope Sky-Watcher Evostar 150EDX<\/strong>. It transforms your instrument into a faster, larger system, ideal for deep-sky imaging.<\/p>\n Thanks to its 0.77x<\/strong>, It reduces the telescope's focal length while improving overall brightness. This translates into shorter exposure times and greater efficiency during astrophotography sessions. The focal ratio is thus reduced (for example, from f\/7 to approx. f\/5.4<\/strong>), making the instrument more effective on faint objects such as nebulae and galaxies.<\/p>\n In addition to reducing the focal length, this accessory acts as a field corrector<\/strong>, This improves the sharpness of stars throughout the image. The edges of the field are better corrected, limiting distortion and coma, which is essential for modern APS-C and full-frame sensors.<\/p>\n Its multi-coated optical design ensures excellent light transmission and high contrast. This results in cleaner, more detailed images with improved color rendering.<\/p>\n This accessory is therefore ideal for astrophotographers wishing to optimize their setup without changing telescope, by improving field of view, brightness and overall image quality.<\/p>\n This gearbox is an excellent choice for improving the performance of the Sky-Watcher Evostar 150EDX<\/strong> in astrophotography, offering a wider field of view, faster exposures and better overall optical correction.<\/p>","protected":false},"excerpt":{"rendered":" R\u00e9ducteur de focale 0.77x pour Sky-Watcher Evostar 150EDX Optimis\u00e9 pour l\u2019astrophotographie, ce r\u00e9ducteur de focale est sp\u00e9cialement con\u00e7u pour le t\u00e9lescope Sky-Watcher Evostar 150EDX.
