  • FarPoint Astro Bahtinov Focus Masks make focusing for astrophotography easy. Works with all DSLR cameras or CCD imagers
    and is great for cameras with or without liveview.

    Simply place the Bahtinov Focus-Mask over the end of your telescope, find a reasonably bright star near your target,
    take a 3-5 second picture and view the diffraction spikes. Change your focus, take another picture and again, view your
    diffraction spikes. Is the center spike moving further from center? Then change the direction your focusing and try
    another picture. Watch the direction the spikes are moving and when the center spike passes the middle of the other two
    spikes, change direction and fine tune your tuning knobs until the center spike is in the middle. Your now in perfect
    focus.

    These are not paper thin masks. Bahtinov masks are made with light weight, thick, yet resilient plastic, will not break
    and will bend only when forced.

    You can check your focus as frequently as you like throughout your imaging session.

    Our masks are designed to match the focal length of your scope.
