Highest Precision Bahtinov Masks

When absolute precision is a MUST, these are the focus tools you need. Incoming light is diffracted through the laser-etched mask at the highest quality. The 16 line Tri-bahtinov tools work for nighttime focus and telescope collimation. 

Developed in 2005 by the Russian amateur astronomer Pavel Bahtinov, the bahtinov focus mask works by diffracting incoming light into a predictable and recognizable pattern which you can then use as a guide to perfect infinity focus. With the mask attached, you'll be able to focus to infinity within seconds, saving you set-up time for nighttime photography. Click here to learn how to use a bahtinov tool
