Summary

This is the Bahtinov mask generated by 1010011011. I have split it into two halves so it will fit in my 3D printer which is 270mm x 200mm.

I printed the two halves, bonded them together at the edges with epoxy, mounted it on the telescope (easy) and tried it out on a bright star. It works just like a Bahtinov mask should. Sharp focusing made easy.

Post-Printing

Glue the two halves together carefully so symmetry is maintained.
