Thanks Dave and John. I've redone this image using a similar LRGB workflow to that in the vid below, but substituted NoiseX, BlurX and StarX for some of PI's native deconv, noise reduction and enhancement tools. I reckon I've ended up with a nicer, more natural looking colour right across the frame - I'll post it in the Big Boys/Gals forum. Still experimenting but that is what it's all about
