Focussing mask design

Hi Folks,

I came across a reference to this new focusing mask on the SiTech Servo Controller mailing list - looks like it might take (some of) the pain out of focussing accurately - it's certainly a major improvement over Hartman style masks. I put the Russian forum announcement & discussion through Google Translate and it turned out quite well - understandable... but with some odd / untranslatable words! Anyway, have a deko. I imagine you could knock one up out of thin card very easily - a lot cheaper than the asking price!

Hi Phil,

This design looks very promising. I first became aware of it thanks to a message on the AP Yahoo forum and which I forwarded locally to various friends. In no time we all had our own designs and cutouts.

It seems to work quite well.
