Looks good, wonder if you lower the black point a notch it might bring up a little more fine detail.

Ok thanks I will give that a try.  I struggle a bit with the processing.  It looks ok on my laptop but then too dark on my phone etc? Do you think this is any better?

Experiment is the key. Maybe try dropping the black point even more to see if more becomes visible, then even further till the background looks bad and then decide on a point somewhere where you are happy.

Here's another attempt at processing my M51 image.  I haven't manage to get any more data but I have tried to further lighten and sharpen the image...

Very good indeed. You've got some great detail in there for a relatively short integration. Your sky quality must be good.

Thank you.  My sky quality is 21.49 bortle 4 according to clear outside for my postcode.  But I am surrounded by 3 LED street lights. There was no moon however which i think made the greatest difference.
