LDN 865

Constellation: Cygnus

LDN 865 is a dark cloud in the constellation of Cygnus. It shows a lot of Ha structures and seems to hide a region of ionized oxygen, of which a “lightning bolt”-like structure seems to emerge towards the south. At the northeastern corner of the image is NGC 6888. Link to interactive sky chart.

Prodtruding from “under” LDN 865 is an Oiii lightning bolt nebula, as if an SNR would hide behind the dark cloud. 

To the southwest is the small planetary nebula NeVe 2 depicted in center of the image on the left.
