I also extended the OIII much further into the image and added contrast the central features of the image.
So, RGB stars will come when this weather passes, and I did reintroduce the mottled green, but didnt like it.

The 'odd star' someone emailed me about is very intriguing. I looked at the raw (Ha) data and this star has a great halo around it. The halo is not present in either the OIII or SII. It is in the lower right of the image.

Well, enough blabber, hope you like this version better: I certainly do!
and thanks for the feedback - a better result has come of it.

cheers
Martin

Very very nice Martin, incidentaly I am working on a rendition of ETA somehow very similar to this with data I collect over the last year and half, I still have to find the sweet spot in blending Ha, OIII and RGB due to the extremely high dinamic of Eta Carinae. I hope to have something done within the next two weeks..

Clear skies
