The 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.

With a 305 mm aperture at f/3.9 and a focal length of 1,200 mm, it is primarily an astrophotography instrument: when used with a camera, it is designed to photograph nebulae, galaxies, and clusters, offering a good balance between field of view and detail.
It can still be transported by car: the tube weighs about 21.8 kg.
Yes, and with care: in astrophotography, an open-aperture Newtonian telescope at f/3.9 requires precise collimation. A collimation laser simplifies the adjustment. 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 aperture of f/3.9, it gathers light very quickly, so exposure times remain short. With a tube weighing approximately 21.8 kg (without accessories), choose a mount with a load capacity that leaves some margin.
305 mm Newtonian optical tube, 2″ Crayford eyepiece holder with 10:1 dual-speed focuser, 1.25″ and 2″ eyepiece adapters, 9×50 finder scope, tube clamps, Losmandy dovetail (Type D), piggyback camera adapter.
