Cave nebula

[libraryman]

Hi all, i need a little help here....

im trying to process the Cave nebula complex...its wide field, Reduced FSQ106, QSI 583..

i know the data is good..and im not an expert but neither am i a novice but im really struggling to get this subject right...

ive tried Pixel math in various combinations...ive tried Images plus...ive tried PS and Hue saturation and clipping masks but i just cannot get the seperation of O111 Sii and HA correct.... or lets say as i want it!!

 

is this target just plain difficult or what!!...i have 12 x 20mins of HA and 30 odd each of Sii and O111all 20min subs...enough i would have thought...

 

any suggestions would be appreiciated but please please dot tell me to get more data...im fed up now....lol!!!
