Last night things went mostly ok until unrelated issues stopped my progress for the night.
However, luminance filter was getting some strange black areas on it that moved from shot to shot (I was rotating between LRGB filters).
Today while I was baking the dessicant again, I pulled apart the filters/camera - and on the luminance filter was part of a leaf/bark floating around. I suspect removing that obstruction will help make the L data a bit better.
