I took a stab at bringing out the dust surrounding the Pleiades in my December 2018 capture. I had no idea the dust was so bright—this is just 10 minutes at f/2.8 (whereas it took 4 hours at f/2.8 to bring out the same amount around the Blue Horsehead):
Canon 200mm f/2.8L II
Canon 600D/T3i @ ISO 800
