What are the details.

Polarisation has something to do with it I gather.

I haven't seen anyone else do it except for Tim Khan after I showed him how to do it.... you let the cat out of the bag.... I was hoping that there'd be a few guesses made as to what was going on there Paul!

Well the answer to that is easy

there's LRGB, Emission Line, Stokes, Polarigram, and a combination of stokes and emission line. - either with or without luminance, and with a rotation from 0* to 135* at 45* intervals

All disclosed in the articles I linked as well as the slidesets, Anni!

You got it right though
