Quick Overview

  • 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

Description

The Quattro imaging Newtonian is an affordable, 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.

Included with the Quattro Newtonian is a 11:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapters, a 6x30 finderscope, tube rings, V-style dovetail plate, a 70° Ultra Wide 22mm eyepiece, and coma corrector/reducer.
