Hi and welcome Eddie. Very nice image with loads of detail.
Just read your camera settings and was a little surprised at the offset setting. I have played a lot with Neb2 and qhy8 and found the offset of about 60 to 70 gives me a nice histogram towards the left hand side which allows the full dynamic range of the camera to be used.
Lowering this may go somewhere to reduce the very black background you have. The black point seems quite clipped.

Hi Doug thank you for the kind comments.
Your right with the offset setting of 60 to 70 moving the histogram towards the left for a more dynamic range - I notice that during my experimentation, I'm using the TVDM drivers which defaults to offset 110 (QHY drivers defaults to 130) under Neb2, because this is my first attempt I decided to use the default setting. I did notice that the image is predominately green when streched the brightness, not sure if the filters are causing this green cast, will attempt Orion again without filters to see if the green persist - just waiting for the clouds to clear.
Cheers
Eddie
