Thanks Nik..I tried what you suggested but I just could not get rid of the green.but I made a difference....I know it's there by turning the saturation way up in the green channel in photoshop and it stands out..was better but finally I reprocessed in StarTools and mapped Ha to the red channel and the red stack to narrow band enhancement and left the green channel empty... that way I figured I would get rid of the green
Thanks again I appreciate the new ( to me) information.
