Skywatcher Newton Quattro 150 + Coma Corrector

Newtonian telescopes have always been the best-selling reflectors as they combine a large aperture with an affordable price. The Sky-Watcher Newton Quattro 150/600 f/4 is a 150mm diameter and 600mm focal length telescope that is particularly well-suited for photographic use, thanks to its fast f/4 focal ratio and the included coma corrector.

This instrument is very fast, allowing for the capture of the finest details of faint objects, but it can still be used for visual observation, especially for viewing galaxies, nebulae, or star clusters. The Quattro Newtonians are the best instruments for observing or photographing faint objects at very low costs. They are designed for deep-sky photography but also perform very well as instruments for observing both faint objects and planets. Weighing only 5.7kg and compact, despite appearances, it can be used on mounts like the EQ3, but we recommend at least an EQ5 for photographic use.

Newton Quattro optical tube with 150mm diameter parabolic mirror, 600mm focal length (f/4), rings with 45mm dovetail bar (EQ5 style), dual-speed focuser with 50.8/31.8mm eyepiece holder, 6x30 finder scope, 22mm Ultra Wide eyepiece with a 70-degree field of view, and included coma corrector.

The included coma corrector further reduces the focal ratio to f/3.45 with a resulting focal length of 518mm, making the instrument even faster and dedicated to deep-sky astrophotography. The coma corrector for the QUATTRO 150 Newton is not compatible with the QUATTRO 200, 250, and 300 models.
