The Tulip Nebula
This beautiful little emission nebula is 6000 light years removed from us.
One of the fascinating things about this region is the objext Cygnus X-1 that is lurking close by.
Cygnus X-1 is a galactic X-ray source discovered in 1971 and one of the first confirmed black holes. It orbits one of the stars in this picture which I highlighted below. It’s actually possible to image the bow shock caused by this interaction, but this would require some monochrome sensor.

Star HDE 226868 is a blue supergiant feeding Cygnus X-1 with stellar winds.
