Visit Sky-Watcher focal reducer \/ field corrector 0.77x<\/strong> has been specially developed for the apochromatic telescope Sky-Watcher Esprit-150 ED<\/strong>. Designed to meet the requirements of advanced astrophotographers, this accessory increases the photographic field of view while improving the instrument's brightness and optical correction.<\/p>\n Thanks to its 0.77x<\/strong>, the Esprit-150ED's focal length is reduced to give a fast focal ratio of f\/5.4<\/strong>. This reduction reduces the exposure times required for deep-sky astrophotography, while capturing a wider field of view. This makes it ideal for photographing extensive nebulae, vast stellar regions or large galaxies in maximum detail.<\/p>\n The corrector uses an advanced optical design with three fully multi-coated lenses <\/strong>(Fully Multi-Coated). This multi-coating optimizes light transmission and effectively reduces internal reflections and loss of contrast. The result is a brighter, sharper image, with pinpoint stars right up to the edges of the photographic field.<\/p>\n The reducer\/corrector produces a corrected, fully illuminated image circle of 36 mm<\/strong>, making it ideally suited to sensors APS-C<\/strong> and compatible with cameras full format<\/strong>. This wide field of view means that the Esprit-150ED's optical performance can be fully exploited with modern, high-resolution sensors.<\/p>\n The system is supplied with a standard adapter featuring a M48 x 0.75<\/strong> and a 55 mm<\/strong>. This configuration is ideal for direct use with Canon EOS and Nikon Sky-Watcher adapter rings, facilitating After removal of the supplied adapter, an internal thread M71x1<\/strong> becomes accessible with a maximum back focus of 75 mm<\/strong>. This configuration offers great flexibility for astrophotographers wishing to use customized solutions including cooled cameras, filter wheels, additional correctors or motorized focusing systems.<\/p>\n The Sky-Watcher 0.77x reducer\/corrector is also compatible with 2-inch astronomical filters<\/strong>. This compatibility enables the use of anti-light pollution, UHC, OIII or narrowband filters, particularly useful for astrophotography from urban areas or for narrowband imaging.<\/p>\n Weighing in at around 910 g<\/strong> caps included, this corrector benefits from a solid, precise construction ensuring excellent support of the optical train. Its high-end finish blends in perfectly with Sky-Watcher's Esprit series, guaranteeing reliable use even with heavy, complex photographic set-ups.<\/p>\n The Sky-Watcher 0.77x reducer\/corrector for Esprit-150ED is an essential accessory for astrophotographers wishing to exploit the full potential of their apochromatic refractor. It provides a perfectly corrected field of view, enhanced brightness and exceptional image quality for modern high-definition sensors.<\/p>\n R\u00e9ducteur \/ Correcteur 0.77x pour Esprit-150ED Le r\u00e9ducteur de focale \/ correcteur de champ Sky-Watcher 0.77x a \u00e9t\u00e9 sp\u00e9cialement d\u00e9velopp\u00e9 pour la lunette apochromatique Sky-Watcher Esprit-150 ED.
