Decided to try out my new narrowband filters on one of my old favorites.

This is a false-colour composite created using Pixinsight with Hα(Red), SII(Green) and OIII(Blue).

Reasonably happy with it, but I seemed to have picked up some background processing noise along the way. If anyone can suggest how best to remove it in Pixinisight please let me know.
