This double nebula has a very interesting design, different than any others I've seen from Sean. Two nebulas appear to be either about to collide, or they have recently (on a cosmic time scale) finished colliding, although it's hard to tell which it is, since we only have this frozen snap shot in nebulaic time. There are stars scattered everywhere, and some other interesting inclusions which you'll have to travel to and study in hand in order to determine exactly what they are. Have fun!! Signed SC 2014.
