Yes that is ,my favourite as well. You've got some distracting yellow/red haloing going on there though. Haloing can be a problem with narrowband imaging when you combine them all together. O111 being close to blue often has quite soft stars. I find a star mask on the Ha and O111 often reduces or prevents these. They are easy to have happen.
