Sky-Watcher Quattro 150P Imaging Newtonian Highlights:
The 6" Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser is optimized for wide-field deep space imaging, 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 6" Quattro imaging Newtonian is ultra-fast and incredibly simple to use. The f/4 optical system allows the user to capture wide field images of 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.
