The Sky-Watcher Quattro 150P Imaging Newtonian is a 150 mm reflecting telescope specially designed for fast, high-quality astrophotography. Thanks to its f/4 focal ratio and its coma corrector includedIt allows very short exposures, while providing perfect coverage of APS-C and smaller sensors. This optical tube is a affordable, high-performance astrographideal for starting out or completing a mobile photographic setup.
Equipped with borosilicate parabolic mirrors treated with the latest exclusive Radiant™ Aluminum Quartz™ (RAQ™) coatingsthis telescope reaches a reflectivity of 94 %. The oversized secondary mirror ensures optimal illumination for full-frame DSLR sensors and CCD cameras. The tube is manufactured from rolled steel with a Black Diamond metallic elegant and resistant.

With a 150 mm aperture at f/4 and a focal length of 600 mm, it is primarily an astrophotography instrument: when used with a camera, it is designed to photograph large nebulae, the Milky Way, and large clusters across a very wide field of view.
Yes, it's a lightweight instrument: the tube weighs about 5.7 kg.
Yes, and with care: in astrophotography, an f/4 open-aperture Newtonian telescope requires precise collimation. A collimation laser simplifies the adjustment process. The Sky-Watcher Collimation Guide (EN) explains the procedure.
Yes, that's what it's designed for: it mounts on a motorized equatorial mount (not included) with an astro camera or a regular camera. With an f/4 aperture, it gathers light very quickly, so exposure times remain short. With a tube weighing approximately 5.7 kg (without accessories), choose a mount with a load capacity that leaves some room to spare.
