The characteristic Bahtinov pattern forms three diffraction lines around a bright star. If the middle line is exactly in the center, the focus is perfect. This way, you can be sure that long exposure sessions start out in focus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The mask is 3D printed from PETG plastic: lightweight, strong, and dimensionally stable up to 80 degrees Celsius. The fit is designed for the Seestar S50, ensuring the mask stays securely in place and can be attached and removed in one second.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Bahtinov mask for exact focus confirmation<\/li>\n\n\n<li>Fit tailored to the Seestar S50<\/li>\n\n\n<li>3D-printed PETG: lightweight and dimensionally stable up to 80 degrees Celsius<\/li>\n\n\n<li>In a jiffy to place and remove<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Exclusively suitable for the ZWO Seestar S50.
