Bahtinov mask for Canon 300 f/2.8 lens

[Stefan Buda]

Hi guys,

Recently I made one of these for someone and now I have a spare one that is available for $25.

I have improved my production techniques and I can make these cheaper than before. This particular size used to work out to $35.

Cheers,
Stefan

Sale pending to Andrew, but I can make more if anyone else needs one.

Stefan do you make these for a Canon 135mm f2 lens and a Canon 200mm f2.8 lens. I could give you the dimensions and if so how much. Love your glow in the dark knobs.

Hi Mark,

No problem. I should be able to make those for $20 each. You only need to give me accurate measurements of the locating diameter, which is the inside diameter of the filter thread. But from what I gather, both lenses use 72mm filters and in that case a mask with 2mm slits should work for both lenses.

Cheers,
Stefan

Hi Stefan,
The 200mm f2.8 that you made for me works a treat.
So did the one you made for my Williams 88mm refractor after Vic-South.
I've been using them this evening imaging up in the Flinders Rangers.
Thanks for your effort.
Cheers,
Jeff

Thanks Jeff for the feedback, it's good to know that someone is actually using my creations.

Cheers,
Stefan
