About Sky-Watcher Quattro Imaging Newtonian

Quattro Imaging Newtonian’s are fast, large aperture astrographs, delivering an optical system that excels at both imaging and visual observation.

Built to Perfection
Like all Sky-Watcher reflectors, the Quattro Imaging Newtonian features borosilicate mirrors with a quartz overcoat, producing 94% reflectivity. The optical system uses an oversized secondary mirror, providing greater illumination for DSLRs and CCDs using full-frame sensors. The optical tube is constructed with rolled steel, and features Sky-Watcher’s signature glossy metal-flake Black Diamond finish on the exterior.

Jack of all Trades
Did you know the Quattro Imaging Newtonian is also an excellent visual observation instrument? Although this optical tube is excellent for deep sky imaging, the wide aperture and short focal length produces a bright and vivid viewing experience. If you’re looking for one optical tube to use for both visual and photography, then look no furth er than the Quattro!

Sky-Watcher Quattro 250P
The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2? dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography. Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector.
