Like the Dumbbell nebula in Vulpecular, it's amazing how many images are going super deep on the Helix these days too  , not so long ago, if you picked up the main "eyebrow" well, you were bloomin well cheerin! 
Well done indeed 
Question, was that done with the lens wide open at F2.8?

Many thanks Mike! That’s a good suggestion, I’ll have another look and see if I can boost the star saturation
I use a small 3D printed aperture mask on the lens so it is operating at f/3, which I found tightened the stars a little and with the 5nm filters I wasn’t really losing any significant speed
