Sky-Watcher Quattro 150P Imaging Newtonian Highlights:

  • 150mm aperture, 600mm focal length 
  • Fast f/4 focal ratio 
  • Parabolic borosilicate mirrors utilizing Sky-Watcher’s proprietary Radiant ™ Aluminum Quartz (RAQ™) coatings designed for imaging with 94% reflectivity 
  • 11:1, dual-speed, 2-inch Crayford-style focuser 
  • Oversized secondary mirror produces greater illumination for full-frame DSLR and CCD cameras
  • Primary and secondary mirrors are both collimatable 
  • Included coma corrector is designed to match the 600mm focal length, ideal for APS-C sensors and smaller
  • Imaging focal ratio with included coma corrector/reducer is f/3.45, focal length is 518mm 
  • Includes tube rings, mounting plate, eyepiece adapters, 70° Ultra Wide 22mm eyepiece, coma corrector/reducer, and a 6x30 finderscope 

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.
