Thank you so much guys
It was very interesting to re-process this image. I was not very happy with the 2005 processing and that's why i waited to improve my processing technics. And 5 years later........
Mike : Thanks
. Yes, i think the heart of this nebula will be interesting to take with the ASA Astrograph to have got more resolution on this part. I keep you posted about this project.
Thanks once again.
