  IC1311 is an open star cluster located within a very large interstellar emission complex in the constellation Cygnus near the Gamma Cygni Nebula complex named IC1318.
IC1311 was discovered in 1893 by British astronomer Thomas Espin and is estimated to be 1.6 billion years old and containes over 800 stars.
The dark nebula to the right of IC1311 is LDN885 and seen above LDN885 is the very small and faint planetary nebula Patchick 6.

2 hour exposure taken with a 5nm Hydrogen-alpha (Ha) filter showing the nebula structure the open star cluster is located in.
This was used as the luminance channel.
The same 2 hour exposure with the star removed to show the complex structure of hydrogen and dust.
The dark nebula at the 3 o'clock position is LDN 885 and above that  you can see the small round planetary nebula Patchick 6.
