Focus mask for Seestar S50

Focus mask for Seestar S50: focusing with certainty

With this Bahtinov mask, you can check the focus of your ZWO Seestar S50 with absolute certainty. 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.

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.
