SKYWATCHER QUATTRO 150P f/4

The Sky-Watcher Quattro 150P Newtonian is a fast astrograph designed for both astrophotography and visual observing. With a fast f/4 focal ratio, it delivers exposure times up to six times shorter than a typical f/10 Schmidt-Cassegrain.

Though optimized for imaging, the Quattro also provides bright, detailed views for visual astronomy. Its borosilicate mirrors feature Sky-Watcher’s high-reflectivity Radiant™ Aluminium Quartz (RAQ™) coatings, achieving 94% reflectivity. The rolled steel tube is finished in Sky-Watcher’s signature glossy Black Diamond coating for durability and style.

An oversized secondary mirror ensures large illuminated filed for astrophotography cameras cameras, including full-frame models. The included coma corrector/reducer further enhances image quality across the field.

Included Coma Corrector:
This Newtonian telescope includes an aplanatic coma corrector. Its four-element optical design—featuring ED glass—minimize the coma aberration seen in standard Newtonians, delivering sharp, pinpoint stars across the entire image field.

The corrector features an M48 male thread and a 55mm back focus.
