Visit Sky-Watcher Quattro 300P Imaging Newtonian is a 305 mm Newtonian telescope designed for demanding astrophotography. Thanks to its 1200 mm focal length and its ultra-fast f/4 ratioThis 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.
Built around a borosilicate parabolic primary mirrorQuattro 300P features the exclusive Radiant™ Aluminum Quartz™ (RAQ™) ensuring reflectivity of 94 %. Its oversized secondary mirror ensures even illumination of sensors up to full format.
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.
