Very impressive that you've got such a good dynamic range here. I've also imaged this object and the stars in the middle can overwhelm the nebulous material. No doubt the Halpha helped.

Thanks David. It's a very clear night here in Bournemouth, so I'm taking advantage of it. I'm currently doing both narrow band Halpha, OIII and SII as well as LRGB for the Bubble Nebula. I just had to post that initial image because I was surprised that in just one exposure I could see so much detail. Narrow band filters definitely  help in a sub-urban location. Thankfully, as I'm to the North edge of the town I have dark skies to the North so I try to concentrate on objects near the pole.
