The Bahtinova mask is an unparalleled help in focusing on digital astrophotography. Focusing the image of a bright star (the clearer it is, the easier procedure is) we are sure to precisely "hit" the focal point. There is no need, as it often happens, to seek out the focus by trial and error.

Masks currently appear in golden color, with identical functionality.



• for telescopes with an aperture in the range of 85 - 120 mm
• Active diameter: 80 mm
• greatly facilitates focusing for astrophotography
• is more sensitive to defocus than digital methods (FWHM, FocusMax, Robofocus etc.)
• a universal system for attaching the mask on the tube (special pins)
• made on a digital machine tool made of resistant plastic

>> FREQUENTLY ASKED QUESTIONS <<

Question : How does the Bahtinov mask work? When do I know that the image is sharp?

Answer : We choose the brightest possible star. We preset the focus. To set the focus precisely, let's see the appearance of the star near the sharpness setting.



• on the left: the center radius unevenly distant from the outside - we are away from the focus; radius
• measure: it is better but still not perfect
• on the right: the central ray is evenly distant from the external rays - the focus is set

Question : How do you attach the mask to the telescope?

Answer : It's best to make such a frame as for a solar filter, vide: http://teleskopy.pl/filtrsloneczny.html
