Bahtinov Mask for OD 63 to 89mm, Focusing Mask Aluminum Alloy Focus Fishbone Astronomical Part Focusing Mask for Astronomical Telescope
- UNIVERSAL COMPATIBILITY: Suitable for all types of telescopes including reflectors, refractors, for Dobsonians, for Mak Cas, and for SCT, fitting telescopes with an outer diameter of 63 to 89mm. The focusing mask can be easily installed on any telescope with 3 bolts.
- PRECISE FOCUSING: The Bahtinov mask eliminates guesswork during focusing, overcoming visual conditions to quickly and easily achieve optimal focus for your telescope.
- SECURE GRIP: Three metal columns of the mask clamp the telescope to prevent slipping while keeping the mask perfectly centered. The 3 column design allows for central alignment and compatibility with a wider range of telescopes.
- DIFFRACTION PATTERNS: The focus fishbone acts as a set of artificial trusses. As light passes through the fishbone plate, it diffracts in 3 different directions, creating 3 pairs of rays. With focus adjustments, the ray patterns move until the 3 sets of rays align, indicating proper focus.
- LIGHTWEIGHT AND ALUMINUM ALLOY: The telescope focusing mask features a thin and sturdy design made of 1mm thick aluminum alloy material, lightweight and to maintain balance without damaging the telescope.
