Working on the outer regions of M27 for under 3 hours at f/5 from the city... But how, Holmes?

I didn't expect such a result myself. I shoot in the suburbs, about 4km from the city. There was no moon at all. And processing the outer regions, oddly enough, was the easiest part here. I struggled with refining the main area.
