Thanks all, yes mapped Ha to Red, OIII to Blue. I think overall my subs turned out to be too long. (600 seconds) - the autostretch was way too aggressive and brought the background up to much in both Ha and OIII. My area is around Bortel 3.5 and the was no or almost no moon. I ended up with manual histogram transformations until I was satisfied. Oh well, this was only second light for this combo. I guess more time out with it will improve things.
