Bahtinov Mask Cover for WO Telescopes

Description

A Bahtinov mask that doubles as a protective dust cover for William Optics telescopes. When placed over the telescope aperture, the mask generates a distinctive diffraction pattern on bright stars, allowing you to achieve precise focus quickly and reliably. When not in use for focusing, it serves as a standard dust cap to protect the front optic. Available in sizes to fit various William Optics telescope models.
