    This focusing aid enables astrophotography to be clearly focused in your telescope or with a camera lens. Attaching the Bahtinov mask to your telescope is very easy, it is simply screwed onto the front with a M48 lens thread.

    Follow these steps to effectively use the Askar Bahtinov mask with your camera on a telescope or lens:

    • Put the mask on the telescope and point it at a bright star
    • Turn on the camera and observe the constellation on Live View or on the computer
    • If the recording is not exactly sharp, the center line is shifted. Adjust the focuser until the central line runs right through the center of the star
    • You have now reached the optimum sharpness. Remove the mask from the telescope and you can start exposing the picture
