Bahtinov Mask for Camera Lenses
Focusing a camera lens in the dark represents the most challenging operation for amateurs and professional astrophotographers, and night photographers. Traditional Bahtinov masks have been in use for astrophotography in relatively large aperture telescopes. This type of mask delivers a diffraction pattern, creating a set of three fine spike lines around a bright star. Once the three lines are aligned in a single spot, the focus is achieved.
These masks adapt to the lenses like a lens cap. You must indicate what size you need. Currently we support the following standard sizes in mm: 37, 39, 43, 46, 49, 52, 55, 58, 62, 67, 70, 72, 77, 80, 82, 86, 90, 95, 100, 105.
Custom sizes can be requested (a small surcharge applies).
This model is suitable for lenses over 75mm of focal length. If you want a Bahtinov mask for shorter focal lengths, you should consider the Skylabs Enhanced Bahtinov mask.
