Bahtinov mask for 6" Skywatcher telescope

A Bahtinov mask designed for 6" Newtonian telescopes, including the Sky-Watcher 150P Quattro, offers a precise focusing solution similar to the telescope's dust cap. Crafted with compatibility in mind, this mask conveniently mounts onto the telescope's front aperture, just like its dust cap counterpart. Its design incorporates angled slots that produce diffraction spikes around bright stars. By adjusting the focus until these spikes converge into a central pattern, users can achieve optimal focus effortlessly. This versatile Bahtinov mask enhances the viewing and imaging experience for a range of 6" Newtonian telescopes, ensuring clear and sharp images of celestial objects.
