ok this has crashed 4 times trying to post here..........
so i'll be brief.
thanks for your comments Mike Ross and Jase, i've learnt a bit from blending, thank you. and i take your point on the registar data being hidden.
In the quest for the outer shell i realised i need to push the subs to atleast 15 mins. my previous sub max was 10 mins. did a 10er to see if everything was working. all good. then 20 mins all good so went for 30 all good. so here is a blend of RGB and Oiii (no Ha). i've got some shell woohoo (but probably a bit overtoasted - i always seem to redclip in LAB curves).
So good to know i can punch out 30 min subs now but this thing probably needs hour length subs!

happy for now but no doubt more experimenting to come.
Cheers
