While waiting for the clouds to part again, I thought I would process the OIII and Ha data I had so far into a bi colour image. Not sure about how it looks as the OIII did not seem to have much impact but still worth showing the development so far.
Edit I have done a reprocess of this data. David's comments prompted me to take another look at this and I am quite happy with this now. What do others think?

I like the detail of this data but the elongated stars at the top due to tilt and mis-collimation is annoying. Now that I have the flattener and the adapters should be on the way today I can start to think about sorting that problem out in the near future.
Looks really good Paul; some nice detail in there! .. and more improvements to come with the flattener on its way.
One question, if this is a bicolour image only (Ha -> red and OIII -> blue?) how come your star cores appear white (neutral)? Have you used the Ha/OIII as luminance or something else?

No I did not use the Ha/OIII combine as luminance and wondered the same things myself. I like you was puzzled about the star colours. However, a previous image (Helix) done in bi colour had the same effect on the stars. The only thing I think that might explain this is that I have use the Ha/OIII combine as the green and that would produce a white star perhaps.

Yes clear skies have been rare this year so far. Although there is some word that another drought is approaching with the el nino conditions in the pacific, so that might mean clear skies again next year. I think I remember 2007 being this cloudy before the drought started in ernest.
looking great paul, the curvature can be eliminated in PS with the lens correction filter, under the custom tab, remove distortion -12 worked pretty well for me!
Thanks guys for the comments, I really appreciate everyone taking the time to make a comment.

The mind boggles!
Yep set up and go to bed at a normal hour, in the mean time the system works away gathering data. That is how it should be for everyone.

Well I have done just that and learnt a new trick today. Thanks Pete. I used a lesser setting but it worked.

Thanks Fred. Yes I am planning on picking up some SII as soon as the skies clear for me. I need about 7-10 hours and that will give me enough data then to do another rendition. Did you find the OIII on this object was a bit thin?
