[AstroFest] The tale of two nebulae

Folks, I know I said I was scraping the bottom of the barrel before, and I really didn't think this one would give much but this one positively surprised me In my efforts from suburban Sydney before I hadn't knowingly caught the colours of the star clouds that are starting to show in this shot, and the detail in the nebulae also really starts to be coming out now with a few photons on the sensor. I'm pretty happy with this, but always happy to improve and learn

This is with my little WO Zenithstar 71 (+reducer/flattener) on EQ6 and an unmodded Canon 1100D recording the photons...ISO1600 60x 1m exposures (I'd tripped over my tripod and couldn't get my drift alignment very good ), with biases and 20 darks.

There's a few Mr Blobbies in there...any tips how to de-blob them, or give them diffraction spikes or something else to make them less offensive? I've already used a star mask to keep most of the stars under control while I stretched the nebulosity out. But that skill terminates here Can I just go through the motions with that process again and just select the biggies?

Suggestions/tips always appreciated
