...We need some advice from an experienced QHY8 user... Anyone?

I think this was the problem. I debayered in Iris using the 40D settings. It is suppose to have the same arrangement of colour. This is obviously not correct. I have debayered it in Deep Sky stacker which has a channel for the QHY8. This gave much better colours- red nebula without red stars. Then a "asinh" stretch in Iris and some noise reduction resulted with the attached image. Much better and amazing for a single 5 min exposure with no dark or flat.
