Quick Overview

Bahtinov masks are an essential aid for precision focus in astrophotography. In fact they allow you to focus with greater precision than the one obtained watching the star on your computer screen! To do so, after installing the Bahtinov mask in front of the telescope (like a cap), point a bright star and you will notice the light rays that move away from the central star: move the focuser until the central ray is perfectly in the center and you will be in focus! This makes this method faster and more accurate for focusing, in addition being less sensitive to atmospheric turbulence.

The Bahtinov masks can be used with different diameter telescopes, you can choose from the list the one that is compatible with the diameter of your telescope dew shield. Each Bahtinov mask is equipped with 3 screws with rubber to avoid damaging the dew shield. Place the screws in the slot of the mask and fix the position that best suits your dew shield so mask is safely fixen in front of the optical tube.
