With the overexposed core, 5 seconds with a filter seems low (or the post processing did that)

But in a bortle 9 sky, i can't imagine 5 minutes exposure at f/5.6 giving anything else than overexposed sky.

They used the l-enhance filter and shot at ISO 400, even in bortle 8/9 with that filter on my Astrotech AT65EDQ and a D5300 I had to 10 minute exposures at ISO 400 to really see much.
