Product Information
About
Value 3-Pack Multi-Size Kit: Includes 3 different sizes of Bahtinov masks in one package to fit a wide range of optical tube diameters. Perfect for amateur and professional astrophotographers who own multiple telescopes, guide scopes, or DSLR/mirrorless telephoto camera lenses.
Precision Sharp Focus in Seconds: Eliminates the frustrating guesswork of focusing on faint stars. Our premium diffraction grating structure creates distinct, razor-sharp 3-line spike patterns, allowing you to achieve 100% flawless crystal-clear focus quickly and effortlessly.
Ultra-Clean Precise Laser Cutout: Features mathematically optimized, clean grid lines with zero burrs or warping. The high-contrast design ensures maximum light transmission and sharp diffraction spikes even when focusing on dimmer, lower-magnitude stars.
Lightweight & Scratch-Free Material: Molded from premium, impact-resistant, and lightweight polymer. Unlike heavy metal aluminum masks that can scratch your expensive lens coat or unbalance your tracking mount, our masks offer sturdy, all-weather outdoor durability without adding extra weight.
Easy Slip-On Secure Fit: Designed for quick attachment and removal in pitch-black dark sky environments. The low-profile outer rim slides easily onto your telescope's dew shield or lens hood, staying firmly in place during vertical tracking or windy nights.
