How can the GoldFocus Mask be used for visual observing or film photography?
The GoldFocus Mask can be used without the GoldFocus Analysis Software in a manner similar to the Diffraction Cross, Modified Hartmann, or Bahtinov masks. When used without the GoldFocus Analysis Software, the objective is to center the diffraction fringes by visually assessing their location through the telescope eyepiece or a film camera viewfinder. When used without the GoldFocus Analysis Software, the GoldFocus Mask is noticeably more precise than the Bahtinov, Diffraction Cross, or Modified Hartmann masks due to the optimized design of the GoldFocus Mask. When used with an astronomical CCD or DSLR camera and the GoldFocus Analysis Software, the GoldFocus Focusing System is 10-20 times more sensitive than other focusing methods.
