Sky-Watcher Quattro 300P Imaging Newtonian - 305 mm f\/4 Astrographic Telescope<\/h1>\n

Visit Sky-Watcher Quattro 300P Imaging Newtonian<\/strong> is a 305 mm Newtonian telescope<\/strong> designed for demanding astrophotography. Thanks to its 1200 mm focal length<\/strong> and its ultra-fast f\/4 ratio<\/strong>This tube allows you to capture deep images with maximum signal in minimum time. This tube is perfectly suited to the full-format sensors of digital cameras and SLRs.<\/p>\n

A powerful tool for photos and visuals<\/h2>\n

Built around a borosilicate parabolic primary mirror<\/strong>Quattro 300P features the exclusive Radiant\u2122 Aluminum Quartz\u2122 (RAQ\u2122)<\/strong> ensuring reflectivity of 94 %<\/strong>. Its oversized secondary mirror ensures even illumination of sensors up to full format.<\/p>\n

Although optimized for imaging, this tube remains perfectly usable for visual observation, offering bright, detailed images of nebulae, galaxies, clusters and faint deep-sky objects.<\/p>\n
