Bahtinov Mask Generator

This is a customisable bahtinov mask generator for astronomy/astrophotography that will generate bahtinov masks that can be fitted over your telescope or lens. The defaults are set for a Celestron Origin as that's what I have available for testing output.

The generator will produce rims to go inside or outside your dew shield /hood etc. and you can choose to have a core obstruction, hole of full mask.
