Camera lens Bahtinov Mask from 52mm UV filter and black permanent marker?

[Ags]

I am thinking of making a Bahtinov Mask for my camera lenses from a cheap UV filter. I will just draw on a multi-line Y pattern with a black permanent marker. Any reason why this wouldn't work?

I don't know, but I have printed a Bahtinov mask onto acetate in an inkjet printer then cut it down to the correct size for placing in a Cokin filter holder. Not used it yet though !

My thoughts is that 'permanent ink' marker pen may smudge or wear off eventually when you clean it... or you purchase a ready made Bahtinov Mask.

I got a 3D printed one made by @Philippe LECA... http://www.astrokraken.fr/clipsable-bahtinov-mask-for-standard-diameter-dslr-lens-a137731510 
I would order through his site as above. His status is showing that he last visited SGL on February 13th 2020.

Why would I clean it?

Perhaps the indelible ink will be too transparent, that would be my first thought.  Sounds like you have nothing to lose, as the marker will likely clean off with alcohol should it fail anyway!

I thought of that too, but on the other hand people sell transparent Bahtinov Masks?

When I made a Y Lord mask there was a set measurement to use for the aperture used, I did a 50mm, and one of them would be easier to measure and draw.
