Erik yeah could be the light pollution. If the light is white (moon) then the increased sensitivity to green of the camera may cause it to be picked up this way. I'm not confident in my guiding to get 600s frames.
My next investment is either a proper guidescope rather than a finderguider, or an OAG module.
DBE does remove the green just fine. It removes any "background" and in this case it picks up the background as green. I was more wondering if it's normal for them to be green to begin with.

Yes I noticed that, though I thought it was the result of not knowing the software and inadvertently focusing on a star that was no where near the centre of the frame. My field is anything but flat, something that I still need to solve. I've got the camera directly threaded into an adapter and directly to the back of the scope so any lack of flatness is either my mirror or the QHY10 itself. Either way the QHY10 came with a tilt adjusting ring so I may make use of that.
