The Flying Dutchman is a legendary ghost ship that can never make port and is doomed to sail the oceans forever. Sightings in the 19th and 20th centuries reported the ship to be glowing with ghostly light. If hailed by another ship, the crew of the Flying Dutchman will try to send messages to land, or to people long dead. In ocean lore, the sight of this phantom ship is a portent of doom.
South of Antares, in the tail of the nebula-rich constellation Scorpius, lies emission nebula IC 4628. Nearby hot, massive stars, millions of years young, irradiate the nebula with invisible ultraviolet light, stripping electrons from atoms. The electrons eventually recombine with the atoms to produce the visible nebular glow, dominated by the red emission of hydrogen. At an estimated distance of 6,000 light-years, the region shown is about 250 light-years across, spanning an area equivalent to four full Moons on the sky. The nebula is also cataloged asGum 56 for Australian astronomer Colin Stanley Gum, but seafood-loving astronomers might know this cosmic cloud as the Prawn Nebula. (text from APOD)

I re-collimated the 'scope, (again) - makes a huge difference to overall sharpness & contrast - big difference in learning too - compared to
my version from 4 years ago!
but not too crunchy and broad in the processing, so it still looks like a gaseous nebula, nice job 
A wealth of detail in there and definitely a step up from your previous attempt. A 10"F/4 certainly helps with sucking in the photons and increasing that detail however
