I'm starting to go cross-eyed processing this one so I'm throwing it out for comment
I have collected about 25 hours of Ha and 50 hours of OIII on this little gem. The faint OIII shell is now a little brighter and showing some nice details.
Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon 3nm Ha and OII
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Processing: PixInsight
A full res version is available on Astrobin:

Constructive criticism is always appreciated... just don't tell me I need more data
Edit: new version has RGB stars and minor tweaks. I think it is a nice improvement.
Cheers,
Rick.
