The masks of Bathinov are in Astrophotography a very useful tool for focusing.

They can be used for all optical systems, provided the correct diameter is chosen. The diameter in millimeters is specified in the product title. For a telescope with, for example, 80 millimeter opening you should buy the mask "Tri-Bathinov 80", etc.

Each mask comes with three pins that can be variably adjusted. Just put the mask on the front of the tube and set a bright star. On the computer monitor or the display of the Spiegelrefelxkamera you see a diffraction figure of the star. Focusing is achieved when the middle rays are exactly in the middle of the other two rays.

The Tri-Bathinov is a modernized mask that allows you to achieve an even more precise focus with up to 18 lines.
