Bahtinov Mask Generator

thingiverse

This is a repost of my original and popular Bahtinov Mask Generator that was accidentally deleted in October 2020. This version is the latest edition, last revised 18-nov-2020. This revision increases the max outer and aperture diameters to 500 and 495, respectively. Use the customizer controls to set the outside diameter of the mask as well as the center hole if your telescope has a secondary mirror. The "outer diameter" is the physical outer diameter of the mask, while the "aperture" is the inner area that light can pass through. The difference creates a border, that's all. If you are using the mask with a telescope that has a corrector lens (SCTs, Maksutovs, etc), attach felt pads/feet to the side of the mask that faces the corrector to further protect it.
