Bahtinov Mask for 16″ Ritchey-Chrétien-Cassegrain Telescope The Bahtinov mask, also known as the Bakhtinov mask, is a focusing aid designed for amateur telescopes, similar to the Scheiner aperture. This innovative tool is essential for astrophotography, where precise focus adjustment is critical. The Bahtinov Mask is placed in front of the telescope's primary lens and creates a radial pattern within the observer's field of view. As the ideal focus point is set with greater accuracy, the longest beam will appear more centrally aligned. Focus is achieved when the image becomes completely symmetrical. Mahdi Abokhalaf deserves special recognition for his precise calculations used to design the Bahtinov Mask. The Bahtinov mask offers several advantages over other focusing aids. Its unique design allows a substantial amount of light to reach the observer, making it suitable for a wide range of observing conditions. In contrast, the Scheiner aperture is better suited for bright stars due to its lower light intensity.
