You are certainly getting there Alex,
can't wait for some LRGB!

Peter,
I don't doubt your knowledge of the subject at all, but I have also noticed
this pattern on a few of my DS stacks with a drive artifact similar.
I can totally remove it with a better corrected dark frame (bad pxel
mapping in Nebulosity). Sorry for the OT post Alex!
