>> FREQUENTLY ASKED QUESTIONS <<

Question : How does the Bahtinov mask work? When do I know the image is sharp?

Answer : We choose the brightest star possible. We set the focus initially. To focus precisely, let's see the appearance of the star close to focus.



• on the left: the central ray is not equally distant from the outer rays - we are far from focus; radius
• middle: it's better, but still not perfect
• on the right: the central ray is equidistant from the outer rays - the focus is set
