A good start Andy but perhaps you have your RGB files mislabelled. At a guess you have blue and red swapped. I did not see any yellow in the reflection nebs unless that is the Ha?

I sometimes swap my red and blue in CCDsoft as it labels the files red or blue but in reality I swap them to help with blue extinction (I want blue to be exposed before red usually whilst the scope is higher in the sky). My first LRGB looked like yours until I realised I had blue and red swapped.

Or is it simply the Ha component?

Greg.
