Product Highlights
  • 6" / 150mm Aperture
  • 600mm Focal Length
  • f/4 Focal Ratio Optimized for Imaging
  • Highly Reflective Borosilicate Mirrors

The 6" f/4 Quattro Imaging Newtonian Telescope from Sky-Watcher is a large-aperture astrograph, ideal for users searching for a fast-imaging system that will work for both astrophotography and visual astronomy. Boasting a swift f/4 focal ratio, this astrograph can produce an exposure 6x faster than the average 8-inch f/10 Schmidt Cassegrain telescope (or 8.4x faster with the included coma corrector/reducer). Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy.

Like all Sky-Watcher reflectors, the Quattro Imaging Newtonian features borosilicate mirrors coated with Sky-Watcher's proprietary Radiant Aluminum Quartz (RAQ) coatings, producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher's signature glossy metal-flake Black Diamond finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an included coma corrector/reducer for those who want to take their imaging to the next level.

  • 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" 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
