Hopefully you'll agree that this is my best 3D effort yet, I think I've stumbled upon the most effective workflow, using 3 different luminance mask selections for the key nebulosity structures.
Pretty cool. Did you arbitrarily place the stars in different 3d planes or was their a more scientific approach using astrometry information on their distance used?
Thanks chaps! Alas I don't use astrometry data, just my best approximation, though all the background stars are stripped from the original Pleiades image.
