Bahtinov Mask: Explore Scientific 80mm EDT

thingiverse

Thank you to all who contributed to making the very useful "Universal Bahtinov Mask Generator" tool: https://www.thingiverse.com/thing:4581618 Used this tool to make a mask for an ES 80mm scope...worked great on the first print... great diffraction spikes both with & without the 4x powermate I chose to make the mask fit the lens housing so I could still place the dust cap on the dew shield over the mask. Used a few small felt pieces on the lens facing side of the outer ring of the mask to keep the mask a few mm above the lens face & so it is easy to remove.
