Sky-Watcher Quattro 150P f/4 Newtonian Telescope + Coma Corrector

Sky-Watcher Quattro 150P f/4 Newtonian Telescope + Coma Corrector

Description

The Sky-Watcher Quattro 150P f/4 is a fast Newtonian imaging telescope ideal for short-exposure astrophotography and high-quality visual observation. With its 600 mm focal length and 150 mm aperture, it delivers a fast f/4 ratio, allowing efficient light capture.

It includes a modified M48 aplanatic coma corrector (effective focal ratio f/3.45, 518 mm), enhancing star sharpness across the entire field and reducing coma — especially valuable for APS-C sensors (image circle 21.7 mm, 55 mm backfocus required).

The 2" Crayford focuser with 10:1 micro reduction is supported by ball bearings to handle heavy cameras and provide ultra-smooth, backlash-free focusing. The fine focus knob allows for ultra-precise adjustments under demanding conditions.

A parabolic primary mirror and ultra-thin 0.5 mm secondary holder ensure better contrast and reduce diffraction. Also included are a 6x30 finderscope and standard 45 mm dovetail bar with tube rings.

Compact (41 cm length) and lightweight (5.7 kg), this telescope is easy to transport and install. Note that this Quattro model does not include internal baffles.
