Really good result Peter, you have all the halo as far as I can see and some good detail in the main PN. I think your scope benefits well from using NB filters.
Purely from an aesthetic point of view, I agree with Rick about the stars but looks like you only gathered Ha and OIII so coloured stars were out of the question. Looks like the stretching has upped the noise but overall I'd rather see the faint bits at the expense of a bit more noise anyway
Nice job...Astrofest just keeps on delivering
