The Sky-Watcher 10" Quattro Imaging Newtonian OTA is a fast f/4 Newtonian reflector specifically engineered for wide-field astrophotography and visual astronomy. With a large 254mm aperture and shortened focal length optimized for prime-focus imaging, this telescope delivers exposures six times faster than typical f/10 systems, making it ideal for capturing nebulae, galaxies, and star clusters. Featuring fully multicoated borosilicate parabolic mirrors with 94% reflectivity, an oversized secondary mirror for full-frame DSLR/CCD compatibility, and a precision dual-speed 10:1 Crayford focuser, the Quattro combines serious imaging capabilities with versatile visual performance for both amateur and experienced astrophotographers.
