Hi Rob,
They were stretched but there were two main issues. Firstly it was not the darkest of summer nights and I only did 48 seconds (L) and about twice that for RGB data. I know I need to up the colour ones substantially. I also had a slightly dewed up secondary. So disregard the poor contrast, it was just to demonstrate I could get colour. It was first time ever using filters and Pixinsight.
