Difference between L and Ha and ZWO1600 and QSI cameras

I was interested to see what difference there was between Luminance and Ha filters when imaging an object with low nebulosity as seen in NGC2237 (rosette nebula).
Quite plainly the Ha gets it for detail and small stars but interestingly the Ha also has better dynamic range (QSI camera) than the ZWO camera
This is not an extensive comparison as I only managed 7x5min Ha images with no darks etc as I was dodging clouds all night long.
