The Prawn nebula, or IC 4628, is an interesting emission nebula at a distance of around 6000 light years away. It lies in the the tail of Scorpius. The young, hot, massive stars irradiate the nebula with UV light, exciting the hydrogen gas.
Furthermore there are some very interesting dark clouds visible in this area.
Left and right from the ‘dark bridge’ are some areas with dark red structure combined with yellow glow from some stars.
Unfortunately there was quite some high cirrus in the air so didn’t have real nice transparent clear skies when imaging the Prawn nebula. It’s still amazing how much detail you can pick up in these circumstances, but you’ll notice it in the halos around the stars.
