The Sky-Watcher 12" Quattro will bring your imaging into the next level.

The Sky-Watcher 12" f/4 Quattro Imaging Newtonian has . . .
  • 305mm aperture/1200mm focal length f/4 Newtonian reflector optics
  • Fully multi-coated borosilicate mirrors
  • 3” 10:1 ratio dual-speed focuser
  • 8x50 finderscope
  • Tube rings with D-style dovetail bar

The new 12" f/4 Sky-Watcher Quattro Imaging Newtonian with 3" dual-speed focuser has the light-gathering needed for serious wide-field deep space imaging of very faint deep space objects, but can also be used for pleasing visual observing. It incorporates a superbly-figured multi-coated borosilicate optical glass mirror-set. Additionally, the tube length has been slightly shortened to optimize performance for wide-field prime-focus photography. Even better field edge performance for astrophotography, and visual use, can be achieved by adding the Sky-Watcher Quattro coma corrector.

This Sky-Watcher 12" Quattro imaging Newtonian is ultra-fast and incredibly simple to use. The 12" f/4 optical system allows the user to capture wide field images of very faint deep space objects such as nebulae, open clusters, and galaxies over six times faster than using an f/10 system. This gives 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.
