NGC7293 - Helix Nebula
The Sii seemed to contain a lot more noise than the Ha and Oiii integrations. I was trying to focus on lifting out the red sweeping arm and the detail in the background, without introducing too much noise.
I also like green. Not many do, but it adds a nice contrast alongside the surrounding blues, yellows and oranges.
I'm going to try and find time to have another go, and work more on the Sii data
