Description
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
- 8×50 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.
