Description
The Sky-Watcher line of Quattro imaging Newtonians are ultra-fast and incredibly simple to use. The f/4 optical system allows the user to capture an image over six times faster than using an f/10 system, giving you the ability to acquire more images in less time. The Newtonian optical design is one of the most basic, and therefore trouble free, systems available to astrophotographers.
The large apertures of the Quattro line provides resolution of finer detail than smaller, fast refractors. For visual users, the large aperture provides the ability go deeper into the night sky and see fainter objects while still providing a wide field of view.
Also available for the astroimager is the optional f/4 coma corrector. This four-element ED corrector removes the annoying comet-like flair common with parabolic mirrors.
The Quattro line comes complete with 2-inch dual-speed linear focuser, 8×50 finderscope, mounting ring and dovetail bar.
