Product Details

  • Remotely Controlled Bahtinov Mask

    Building on the success of the Alnitak Astrosystems Flip-Flat, Optec has designed the Flip-Mask, remotely controlled Bahtinov Mask.

    A number of customers have asked for a way to introduce a diffraction mask into the light path for remote observatories.  Their solution is the Flip-Mask.  With this new device and proven Alnitak software, automated scripting programs such as ACP, CCD Autopilot, and Maxim D/L can be configured to automatically position a custom size Bahtinov Mask for precision focusing, then remotely move it out of the path once focus is achieved and verified. 

    Optec masks are precision cut on our in-house laser engraving /cutting machine up to 12-inches in diameter.  Contact OPT Sales if you have a different preferred diffraction mask or wish to adapt a mask you already own.  Some weight limitations may apply.


    Bahtinov Masks will be made to match the customer's OTA- up to 12-inch diameter.
